I've been doing some post Christmas tinkering in the garage/workshop.<br />I've taken off about 4mm of chrysalled belly wood and glued on slats of heat treated Yew heart wood. I've used a slat of Yew (~5mm thick) to construct the levers, making them a T section.<br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEgasp1eoL9Aym86dAk0x8wrve1AdjIQTBE4hhKxn-J7jYHzQD5YIfPvUs4X4pGeq6UpOcTfHRl5Yr1jmJp4yau-4tu-1stbHTraeS38XA9lGsbb63LRHkYD7-r6W9J6l4gEsqfVSR1ND4PTvw2Z6eGKs9lrhVUKvzKqBHPvjGjt3vFAU-_BVv2CMV5wEhfv" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img alt="" data-original-height="2169" data-original-width="4108" height="169" src="https://blogger.googleusercontent.com/img/a/AVvXsEgasp1eoL9Aym86dAk0x8wrve1AdjIQTBE4hhKxn-J7jYHzQD5YIfPvUs4X4pGeq6UpOcTfHRl5Yr1jmJp4yau-4tu-1stbHTraeS38XA9lGsbb63LRHkYD7-r6W9J6l4gEsqfVSR1ND4PTvw2Z6eGKs9lrhVUKvzKqBHPvjGjt3vFAU-_BVv2CMV5wEhfv" width="320" /></a></div><br /><br />It's been up on the tiller for a quick shufti and I can see the levers are flexing.(mostly at the inner end) They are bound to flex a bit but I was expecting them to be stiffer. I can experiment by gluing on an additional strip to make them I section, which should help.<br />I used hide glue which can be released with gentle heat, so if necessary I can rebuild the levers a tad thicker and deeper maybe even V section.<br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEgqit2Aeuw-aAurkQRZqwKB_QcvsVMMa4tdY5cAQmbcO2cXEwOxfO9BuTP2_viug4F2ZgE-ACj7_PmKTRyrTglyvupztEvKnYhladLMVTJLOpzbBjLzxAV6ISGO4niKnHqES-pJDlvdNVDmpwsg0Th9uSI2MFkZPreubDyTXfVaWIVU1Fs92w1sM79xtfH0" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img alt="" data-original-height="2042" data-original-width="3450" height="189" src="https://blogger.googleusercontent.com/img/a/AVvXsEgqit2Aeuw-aAurkQRZqwKB_QcvsVMMa4tdY5cAQmbcO2cXEwOxfO9BuTP2_viug4F2ZgE-ACj7_PmKTRyrTglyvupztEvKnYhladLMVTJLOpzbBjLzxAV6ISGO4niKnHqES-pJDlvdNVDmpwsg0Th9uSI2MFkZPreubDyTXfVaWIVU1Fs92w1sM79xtfH0" width="320" /></a></div><br /><br /><p></p>Derekhttp://www.blogger.com/profile/07654835987876553254noreply@blogger.com0tag:blogger.com,1999:blog-5493681473159888383.post-51285444350116772302023-12-06T14:43:00.006+00:002023-12-06T15:12:33.888+00:00Reworking a Flight Bow<p> I've got an old <a href="https://bowyersdiary.blogspot.com/2016/07/quick-test-of-flight-bow.html" target="_blank">Hickory shoot-through flight bow</a> with a chrysalled belly. It was a bit lethal, as I was trying to shoot it, finger loosing it, this set the arrows flexing and they tended to smash. Since then I've made a release aid, and that is probably the key to getting the shoot-through to work.<br />I'm going to rasp/machine off the belly (the chrysals go about 4mm deep) and add a new belly of heat treated Yew heart wood.<br />I'm aiming for 50# at 24" draw with a very light arrow.<br />Most of my stuff is on my <a href="https://www.youtube.com/watch?v=ST-U-eJQXPk" target="_blank">Youtube channel</a> now, but this post is really a log of what I'm aiming for with this bow.The bow is a Mollegabet style and I think the levers are a bit long and heavy, so they may get reduced during test/development.One dilemma is how do I terminate the new belly at each end where the thickness of the original bow increases at the grip and the levers? I'm favouring a simple butt joint, which, being in compression should hold. I'm concerned that if I try and fade it out at each end it may lift or splinter.</p><p></p><div class="separator" style="clear: both; text-align: center;"><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEhpmSUH6YXBybSvN7gd-lfWaWumloVhZAjQeKHlYEci4gPlCVkGfv_mx6UyCyYVRu9snjdirFUf0wTKdaYGYF2M5m8gq08Hio7efBGBL5hd-fJFatAH9ydE1NEtXAlc3C6e83CYW1zkGC8OGk1tseLEBP4h7TmHntSK_4sP2bwX9zk0ujiL_cNMvhUA5cH7" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img alt="" data-original-height="2415" data-original-width="3481" height="222" src="https://blogger.googleusercontent.com/img/a/AVvXsEhpmSUH6YXBybSvN7gd-lfWaWumloVhZAjQeKHlYEci4gPlCVkGfv_mx6UyCyYVRu9snjdirFUf0wTKdaYGYF2M5m8gq08Hio7efBGBL5hd-fJFatAH9ydE1NEtXAlc3C6e83CYW1zkGC8OGk1tseLEBP4h7TmHntSK_4sP2bwX9zk0ujiL_cNMvhUA5cH7" width="320" /></a></div><br /><a href="https://blogger.googleusercontent.com/img/a/AVvXsEhdp0ggI119KlvNUkoBGSX7IHMGu4fWYK1SfqGju07QZyDDtP1dKJerFYPxjDc6Tvud9c3BbYOQW4cG-0XuTFHx_P778soKH4kbIGK_uMjcOJf9se2Qw0aXvNFiS1mtTEymGyx7IERpl8Qo9p_kiYiSNtBR3IuwTRyXKkSNHpM7Sh3pC8338-81i5Eo4HZW" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img alt="" data-original-height="1736" data-original-width="4363" height="127" src="https://blogger.googleusercontent.com/img/a/AVvXsEhdp0ggI119KlvNUkoBGSX7IHMGu4fWYK1SfqGju07QZyDDtP1dKJerFYPxjDc6Tvud9c3BbYOQW4cG-0XuTFHx_P778soKH4kbIGK_uMjcOJf9se2Qw0aXvNFiS1mtTEymGyx7IERpl8Qo9p_kiYiSNtBR3IuwTRyXKkSNHpM7Sh3pC8338-81i5Eo4HZW" width="320" /></a></div><br /><p></p>Derekhttp://www.blogger.com/profile/07654835987876553254noreply@blogger.com0tag:blogger.com,1999:blog-5493681473159888383.post-9135774491752861582023-10-17T11:09:00.004+01:002023-10-17T12:04:08.014+01:00Mkii Archer Automaton<p> </p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEgjtTiMsUw-2in_U_VQTEat02CdiByBhwohxYADz2Ao4je7gtR8RPByi2bMq7Y03T_bfx2VQMmd304P66TLfWlkTAqjdIRY_UGWozoc-Bd7kqUsclF6DHXADlU1GEYMTABzOPlHqGPg3KP8gwlKcHTZmtVxmH6wsQl-R9naIrCaSFVget-_mrzR9NV1c3AI" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img alt="" data-original-height="3487" data-original-width="2026" height="320" src="https://blogger.googleusercontent.com/img/a/AVvXsEgjtTiMsUw-2in_U_VQTEat02CdiByBhwohxYADz2Ao4je7gtR8RPByi2bMq7Y03T_bfx2VQMmd304P66TLfWlkTAqjdIRY_UGWozoc-Bd7kqUsclF6DHXADlU1GEYMTABzOPlHqGPg3KP8gwlKcHTZmtVxmH6wsQl-R9naIrCaSFVget-_mrzR9NV1c3AI=w185-h320" width="185" /></a></div><br />I've got it working pretty reliably now.

The linkages, pivot points, and movements all interact, and the timing between the various motions need to be precise.<br />I've built it up slowly, getting one aspect to work and then progressing to the next. Of course once the next action works nicely, the first one may no longer function! But by then the understanding of the motion has been enhanced.<br />Originally the motor/gearbox mas mounted between the feet, but I've built a plinth such that the motor/gearbox will now be below 'ground level'.<br />The biggest challenge has been to get him to collect the arrow on the string. The next big challenge is the loosing mechanism.<p></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEgUtn2ZI0zKZkYStZK36aAJaZvD6lwBl5GXQn70P6FBHtfkZi9HuMCaiftAtaBtXANn_hcHumJxzHHBwhxxwZdc7Fx3JdQmqh_w25MD7x3Aqmmitu9fOY9-GFhUM8rt8XTCfxUuEfIVP5EE919rjrJtqUTX1uqcjgSOXaUL3bNFbUSTfHZuqvkPC56IZNHD" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img alt="" data-original-height="3204" data-original-width="3803" height="240" src="https://blogger.googleusercontent.com/img/a/AVvXsEgUtn2ZI0zKZkYStZK36aAJaZvD6lwBl5GXQn70P6FBHtfkZi9HuMCaiftAtaBtXANn_hcHumJxzHHBwhxxwZdc7Fx3JdQmqh_w25MD7x3Aqmmitu9fOY9-GFhUM8rt8XTCfxUuEfIVP5EE919rjrJtqUTX1uqcjgSOXaUL3bNFbUSTfHZuqvkPC56IZNHD" width="285" /></a></div><br /><br />Over the development I've had to try 3 different motor/gearboxes, unfortunately the best one stripped an internal tooth. I found some great ones on E-bay, with the requisite very low gearing and hopefully enough output torque to draw the bow. (I'm waiting for it to be delivered).<br />Originally the 2 main movements were on cranks, one of these has been changed to a cam as it can be adjusted to give an asymmetric motion. I'll probably retain the right arm motion as a simple crank otherwise I'll end up with too many variables to adjust.<p></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEg46WTtmohwJYkJWZl_B2MBoWqR9eP-eGo9eKTJVOG0880IyvvjMB1g_wpVbEQ2ykzbwKW_S8snX6vkNlRV66ePBKMa6RHch5Nk2M5ZaB0es9Ufu85S_sGxiinQr0oAuqA-DiaNLY7CBilpIHJu4xV-vv2qO_x9Ivt44MKiDVJQ9GKbGPceOZCwnm1U7ddy" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img alt="" data-original-height="3648" data-original-width="5472" height="213" src="https://blogger.googleusercontent.com/img/a/AVvXsEg46WTtmohwJYkJWZl_B2MBoWqR9eP-eGo9eKTJVOG0880IyvvjMB1g_wpVbEQ2ykzbwKW_S8snX6vkNlRV66ePBKMa6RHch5Nk2M5ZaB0es9Ufu85S_sGxiinQr0oAuqA-DiaNLY7CBilpIHJu4xV-vv2qO_x9Ivt44MKiDVJQ9GKbGPceOZCwnm1U7ddy" width="320" /></a></div><br /><br /><p></p>Derekhttp://www.blogger.com/profile/07654835987876553254noreply@blogger.com0tag:blogger.com,1999:blog-5493681473159888383.post-62334644000925021702023-07-16T13:08:00.006+01:002023-07-16T17:51:18.343+01:00The Lever Bow Lives<p> I'd been showing some people my bows and realised that I hadn't really used the <a href="https://bowyersdiary.blogspot.com/2021/04/lever-bow-test-lessons-learned.html" target="_blank">Lever Bow</a><a href="https://bowyersdiary.blogspot.com/2021/04/lever-bow-test-lessons-learned.html" target="_blank"><br /></a> for fear of it turning itself inside out and exploding if the string missed the string catchers. Ah, but since then I'd made a mechanical release aid for the H bow. Maybe the release aid would suit the lever bow?<br />So, when I went roving this morning I took the lever bow to test the theory.<a href="https://blogger.googleusercontent.com/img/a/AVvXsEgLsZFrg_JIGgiLYyWwD4T6_NLfr79mwFDHSiTnJgwf5jY-m9pEgchV9ca_SnYM3Yfmi7wo3XSGc7AnZXacURzf_WsVcF7jN2vdPL2FZRGdqbJ3h9nX1TSmAdRI0SmsB3ffyTdFLpat24A_QME6RSHKNp7uSbWwVfKKLKQVoOkNPWRgwmaJaChZFUeM6d0I" style="clear: left; display: inline; margin-bottom: 1em; margin-right: 1em; text-align: center;"><img alt="" data-original-height="303" data-original-width="400" height="303" src="https://blogger.googleusercontent.com/img/a/AVvXsEgLsZFrg_JIGgiLYyWwD4T6_NLfr79mwFDHSiTnJgwf5jY-m9pEgchV9ca_SnYM3Yfmi7wo3XSGc7AnZXacURzf_WsVcF7jN2vdPL2FZRGdqbJ3h9nX1TSmAdRI0SmsB3ffyTdFLpat24A_QME6RSHKNp7uSbWwVfKKLKQVoOkNPWRgwmaJaChZFUeM6d0I=w400-h303" width="400" /></a></p><p>Of course, nothing goes to plan and the arrows were loose on the string and were falling off, we tired some wax which almost worked, then someone suggested wrapping a leaf over the string! Brilliant, that's my top-tip it worked a treat. It was hard work drawing the bow, but as the string lifted off the levers, it became more manageable. It was a slightly short draw, but the arrow went off cleanly and must have gone a good 220 yards. maybe I'll try it with a flight arrow some time.Video of the test shot:-<br /><a href="https://www.youtube.com/watch?v=oLkPpS_XQV0">https://www.youtube.com/watch?v=oLkPpS_XQV0</a></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEgz46fuDAs1BD3eXhkLobl8-JlBIX5aV3AV1b8zc6S5sWT86ZecF1xwS8zTCp3ie4rBhLb8XV5xfKCjivIliV-yRgp3Alg6LzELvAUtrDt10hP9F5w5mCW4n7hPf-MDRzzA3vND9zI1xFr-an3CqeNZR6V4xRaV0l8-0J7oEnNDQ-8OwYmdZKOns36wxY0Z" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img alt="" data-original-height="1162" data-original-width="1600" height="232" src="https://blogger.googleusercontent.com/img/a/AVvXsEgz46fuDAs1BD3eXhkLobl8-JlBIX5aV3AV1b8zc6S5sWT86ZecF1xwS8zTCp3ie4rBhLb8XV5xfKCjivIliV-yRgp3Alg6LzELvAUtrDt10hP9F5w5mCW4n7hPf-MDRzzA3vND9zI1xFr-an3CqeNZR6V4xRaV0l8-0J7oEnNDQ-8OwYmdZKOns36wxY0Z" width="320" /></a></div><br />There were only 4 of us roving, but it was lovely weather and there were a good few butterflies in the hedgerow which was nice to see, as I haven't seen many this year.<p></p>Derekhttp://www.blogger.com/profile/07654835987876553254noreply@blogger.com1tag:blogger.com,1999:blog-5493681473159888383.post-14768193606763326272023-06-26T17:20:00.002+01:002023-06-26T17:20:17.333+01:00Ridgeback ii?<p> The Yew primitive I'm working on has a strange feature where the heartwood seems to swell up through the sapwood in a ridge. Pictures in books tend to show perfectly symmetrical logs with the heart sap boundary concentric with the growth rings... but real life isn't like that. I've met it before on an English Longbow, I just ignored it on that one, see this post:- <br /><a href="https://bowyersdiary.blogspot.com/2012/04/weird-heartsap-boundary-emails.html" target="_blank">https://bowyersdiary.blogspot.com/2012/04/weird-heartsap-boundary-emails.html</a>But with this primitive, the ridge is making the limb too stiff. I could scoop out the belly side, but I've decided to scoop out the back instead. This approach seems to be working so far!</p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEhqtuFe3ybyDXRQXiVswlKRnmSJBrUFQCTlvfR70n8Vrwkl3Af6Y_lfALfTzigFxCirm8BgsKhqRraUp_2Qeguqs59zdiiUPNqyMQTbQ-Ycvf5yK6FXjtTCPGGSGZjKaCb77bUz4mjCHRrG_RljEQipr1txS--XKuOTZVQVjQCJ6PTpc7RFcqEcp04vpQMZ" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img alt="" data-original-height="3648" data-original-width="2899" height="400" src="https://blogger.googleusercontent.com/img/a/AVvXsEhqtuFe3ybyDXRQXiVswlKRnmSJBrUFQCTlvfR70n8Vrwkl3Af6Y_lfALfTzigFxCirm8BgsKhqRraUp_2Qeguqs59zdiiUPNqyMQTbQ-Ycvf5yK6FXjtTCPGGSGZjKaCb77bUz4mjCHRrG_RljEQipr1txS--XKuOTZVQVjQCJ6PTpc7RFcqEcp04vpQMZ=w319-h400" width="319" /></a></div><br /><p></p><p><br /></p>Derekhttp://www.blogger.com/profile/07654835987876553254noreply@blogger.com0tag:blogger.com,1999:blog-5493681473159888383.post-54067559002210799122023-06-17T13:26:00.020+01:002023-06-17T13:42:17.451+01:00Camera Weirdness<p></p><div class="separator" style="clear: both; text-align: center;"><div class="separator" style="clear: both; text-align: center;"><br /></div></div> The slo-mo that I took the other day was fine, but I'd taken another video that seemed to have disappeared.

The waist pivots and I've mad two shoulder blades which are split to house the shoulder bearings/joints. It's relatively easy to build up the framework, the animation will be the tricky bit. I'll probably power it with an electric motor this time, or at least with a gearbox from a motor/gearbox assembly salvaged from my last employment.<br />The real challenge is to see if I can make it load the arrow, but that is probably too tricky... we'll see :-)<br /><p></p>Derekhttp://www.blogger.com/profile/07654835987876553254noreply@blogger.com0tag:blogger.com,1999:blog-5493681473159888383.post-17295544224000026402023-04-17T09:20:00.004+01:002024-01-28T08:12:08.350+00:00H Bow smashed and a new camera<p> I bought a new camera off E-Bay, a Sony RX100 iv, it has much better performance and 1000fps slo-mo ( but only for 4 seconds).. the HFR (high frame rate) slo-mo has an interesting feature. You can trigger it before the event you want to film, or after (post trigger)! (It must run a continuous 4 second buffer)<br />I was setting up to try some more slo mo of the H-bow when it exploded, unfortunately I didn't even capture it on video! That's because when it went bang, I didn't have the presence of mind to post trigger the camera as I was too busy swearing.<br />I did some test filming with a bow on the tiller and the quality is vastly better, mind I'm not sure how it will look on youtube as their processing sometimes reduces the quality.</p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEh8UhzgEzNewqgGoa_zvIx0-VSVS50DgiexqQdIvCXjQpRPhKyWr_SLslMJSY5AruUmAV7bmJm0hvwgJ3cBMbHtI0e49Ds8xkKRuaOv0I4MylvvwR0Q-1C4MkubzA_GGy4bZ6OqEJ9K-zK1BeazqwSjhUur32jLrMGoW5LmtSUEczmxCsOn-IVmR8UJOQ" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img alt="" data-original-height="3151" data-original-width="2562" height="320" src="https://blogger.googleusercontent.com/img/a/AVvXsEh8UhzgEzNewqgGoa_zvIx0-VSVS50DgiexqQdIvCXjQpRPhKyWr_SLslMJSY5AruUmAV7bmJm0hvwgJ3cBMbHtI0e49Ds8xkKRuaOv0I4MylvvwR0Q-1C4MkubzA_GGy4bZ6OqEJ9K-zK1BeazqwSjhUur32jLrMGoW5LmtSUEczmxCsOn-IVmR8UJOQ=w260-h320" width="260" /></a></div><br /><p></p>Derekhttp://www.blogger.com/profile/07654835987876553254noreply@blogger.com0tag:blogger.com,1999:blog-5493681473159888383.post-76808503342820002152023-04-12T10:24:00.001+01:002023-04-12T10:24:07.682+01:00Automaton Musings<p> I've been toying with the idea of a bigger improved archer automaton.<br />Maybe steam powered , 8' tall self propelling, sentient and able to take over the world (cackles wildly). Sorry, getting carried away in steam punk fantasy for a moment. But seriously, something more modest, but made of steel with a greater range of movement and maybe 2' tall.<br />My gasless mig welder has proved to be very handy and capable of doing fairly fine work, and the mechanical release aid for the H bow, could well be the basis for the archers hand and loosing mechanism.<br />I have a few other projects to get on with first, but it's good to have ideas bubbling away in the background.<br />I've just bought a new camera off E-bay that should have a much better slo-mo capability (well slightly faster frame rate, but at full screen and decent resolution). I'm also looking at improved lighting, which is needed for high speed photography.<br />The next actual bow I'll be making will be a Rowan primitive.<br />Meanwhile I'm doing a bit of practice shooting into the garage as I've booked into a field shhot at the end of the month... I only do one or two these days and Cloth of Gold is always a good shoot and a chance to meet up with some mates.</p>Derekhttp://www.blogger.com/profile/07654835987876553254noreply@blogger.com0tag:blogger.com,1999:blog-5493681473159888383.post-8080562509720401242023-04-01T08:40:00.010+01:002023-04-01T08:41:33.449+01:00High Tech addition to the H Bow<p> Low tech-high tech!</p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEiIwqgOLawvVjGl4O2MDcYeXdYNNTRJBXVxuBVVMEzj3iK6-hbxBCf1m-q2Bm76Km1fbr5tnLuNETotvrj4G8TanXXgml0HikDao8LmobwRCzgyS_mbWYpUol9-d3BuQ287eOrs2HkedeGO97ba4Q3l-RhcKj1r_9bfTK3_FlKG25_qPjhGDbQv0r-JqA" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img alt="" data-original-height="4771" data-original-width="2926" height="400" src="https://blogger.googleusercontent.com/img/a/AVvXsEiIwqgOLawvVjGl4O2MDcYeXdYNNTRJBXVxuBVVMEzj3iK6-hbxBCf1m-q2Bm76Km1fbr5tnLuNETotvrj4G8TanXXgml0HikDao8LmobwRCzgyS_mbWYpUol9-d3BuQ287eOrs2HkedeGO97ba4Q3l-RhcKj1r_9bfTK3_FlKG25_qPjhGDbQv0r-JqA=w245-h400" width="245" /></a></div>I've made this flight bow ~50# @ 19" draw.<p></p><p></p>The bow itself is made from a single piece of Yew (38" long), slotted down the middle, steamed and then spread apart to allow the arrow to shoot through the centre. <p></p><p>The extended grip allows the short draw to be shot from my usual anchor point. </p><p>A brass weight adds stability, helping to avoid the bow tipping forward until the arrow has left the bow.</p><p>Elevation is shown by a plywood pendulum with a brass weight.

The owner has had some shoulder trouble and asked it I could take it down from 40# to 30#.<br />I like to keep a bow shooting if possible so he's sent it back for me to work on.<br />Seeing a bow after 5 years is great as it's like seeing it for the first time... a very handsome bow.<br />I strung it and had a test shot, it felt very brisk. It's a bit too cold in the garage to work at the mo' but should warm up in a day or too. I'll be sure to take some 'before' and 'after' pics'.<br />We've had block paving done out the front of the house, they did a good job and luckilly finished before the bad weather kicked in. We had it done the same as next door (who had theirs done a week or so back), it makes it all look bigger and 'of a piece'. I'll have to repaing the garage door now, as the arrow holes spoil the look of it!<br />It took a lot of work clean out the garage as it was full of concrete dust where they had to cut across the slab across the garage door. I've finally got the dust all out, and it was a good excuse for a bit of a sort out and tidy.</p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEjI_ZYv7t5pWCpwHNTE6-D4PYM5N57QPpvyT6dhIPM5cgG3v8dWRVSfqr87aw-w1OK2kIb5n5CyJjK0i11UNCrqpUmZtV9jjTlGfc0wHvZwZdQHhei3Gj_1qAQ3vUJGgoo5URqwoeKhNPjqWshdO7q0uoH3IvU3LhuNMpUeXaQ-6wP6pjwGVJ3ndndh9g" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img alt="" data-original-height="3864" data-original-width="5152" height="300" src="https://blogger.googleusercontent.com/img/a/AVvXsEjI_ZYv7t5pWCpwHNTE6-D4PYM5N57QPpvyT6dhIPM5cgG3v8dWRVSfqr87aw-w1OK2kIb5n5CyJjK0i11UNCrqpUmZtV9jjTlGfc0wHvZwZdQHhei3Gj_1qAQ3vUJGgoo5URqwoeKhNPjqWshdO7q0uoH3IvU3LhuNMpUeXaQ-6wP6pjwGVJ3ndndh9g=w400-h300" width="400" /></a></div><br /><p></p>Derekhttp://www.blogger.com/profile/07654835987876553254noreply@blogger.com0tag:blogger.com,1999:blog-5493681473159888383.post-74620549481344430622023-02-26T17:00:00.003+00:002023-02-26T19:36:58.651+00:00H Bow Update<p> I've done plenty of fiddling and fettling to get the H bow shooting but there is still plenty of tuning to do.</p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEjd8IH8mrsYJiDdRYYD_UqAE_y656k-L700_ogkYYrexZ_lqZ2AJc-yItCH3d8GRyZAT6p9M-8teROkTQSHmsUHBx0DO4LboFTgMjXZVI2eYDAR4cMLrPvwAVSVOYqgBQuzlE2mSFmyVT3qx1sAObGiHn6Nvfs6W7dtnVQbKSBFzEhwK2Ee6yuAJxDYcQ" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img alt="" data-original-height="399" data-original-width="231" height="320" src="https://blogger.googleusercontent.com/img/a/AVvXsEjd8IH8mrsYJiDdRYYD_UqAE_y656k-L700_ogkYYrexZ_lqZ2AJc-yItCH3d8GRyZAT6p9M-8teROkTQSHmsUHBx0DO4LboFTgMjXZVI2eYDAR4cMLrPvwAVSVOYqgBQuzlE2mSFmyVT3qx1sAObGiHn6Nvfs6W7dtnVQbKSBFzEhwK2Ee6yuAJxDYcQ=w185-h320" width="185" /></a></div>I went up the club and the first test shot was dissapointing, I hadn't seen the arrow go, so assumed it had gone a prodigious distance!

Now that may seem a convoluted arrangement... but then I'd never pay that sort of money for a stave myself. Anyhow the stave wasn't as clean as I'd have expected... but then you all know I like a challenge. It had a big knot near the middle and a couple of inches of deflex (.eg with tips on the floor, the belly is 2" off the floor) and some twist over its length. It had been roughed out by degrees over the previous year or two and now my mate JT wanted a 120# bow I decided that now was a good time to have a go.</p><p></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEibsqJbSHI8Cl-HIzwWEJ81g47JoJqb_YTxYZYrmL4VToFp8yWi6UscfDuD_iE69tWBKehkUsdp2B3buzGcMw6X3a0pspeVeiS4ot3FHEKNPYedZc1kOWN7bBayydMBe6HPBqR_fgbqeRkohfFFlnVSfp5d3X_nm3fhKEQSyKRKvSpBT2OZn9nemzG78w" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img alt="" data-original-height="777" data-original-width="4808" height="65" src="https://blogger.googleusercontent.com/img/a/AVvXsEibsqJbSHI8Cl-HIzwWEJ81g47JoJqb_YTxYZYrmL4VToFp8yWi6UscfDuD_iE69tWBKehkUsdp2B3buzGcMw6X3a0pspeVeiS4ot3FHEKNPYedZc1kOWN7bBayydMBe6HPBqR_fgbqeRkohfFFlnVSfp5d3X_nm3fhKEQSyKRKvSpBT2OZn9nemzG78w=w400-h65" width="400" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEiVccpgVbI4a-ctHbaSVBt5aNuFhRHgd_-N47WO2RaKRMjUrIBryQ1UzOOPrwKgRPPFwIVGWePOdAPmDo7cBD8_U6p0XGo0B34k7tWi0He4_QCdRljqvE27_tZalyqlr9IbSZcM9G1A3-ssirxC83RgiaFxc5jZJcDyHZ7Q2aU9gzVDYBZSqxXfvRyf1A" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img alt="" data-original-height="3154" data-original-width="4807" height="263" src="https://blogger.googleusercontent.com/img/a/AVvXsEiVccpgVbI4a-ctHbaSVBt5aNuFhRHgd_-N47WO2RaKRMjUrIBryQ1UzOOPrwKgRPPFwIVGWePOdAPmDo7cBD8_U6p0XGo0B34k7tWi0He4_QCdRljqvE27_tZalyqlr9IbSZcM9G1A3-ssirxC83RgiaFxc5jZJcDyHZ7Q2aU9gzVDYBZSqxXfvRyf1A=w400-h263" width="400" /></a></div><br />I'd had the stave for 2 or 3 years and it had shifted a bit over that time.<br />With some careful roughing out and tentatively working in the area of the knot I finally got it to exactly the target draw weight and length (120# @ 32").

The lull after Christmas, so I've been looking back over the year.<br />It's been relatively quiet with ony about 6 bows, a variety of odd projects and a good few repairs.<br />This has all happened with the backdrop of the war in Ukraine and a totally incompetent government lurching from one fiasco to another as energy prices sky rocket. To counter this I've been doing some home improvements to reduce energy bills and I've been getting payment for bow repairs donated to charity rather than given to me... it's not much, but I felt it was something I could contribute from my own effort. This came about when a guy from the Netherlands wanted a <a href="https://bowyersdiary.blogspot.com/2022/06/yew-prod-finished.html" target="_blank">Yew crossbow prod</a>, but import duty would have made it too expensive for him. I'd already started it, so I sent it as a gift on condition that he donated to a local suitable charity.<br />The <a href="https://bowyersdiary.blogspot.com/2022/04/hinged-bow.html" target="_blank">hinged carriage bow</a> was my first interesting project which had been on my to-do list for some time. I reworked a tired old heavy laminate with plenty of thickness at the grip. It worked remarkably well and shot as smoothly as any other ELB.</p><p>Another project from the list was to modify my <a href="https://bowyersdiary.blogspot.com/2022/03/archers-sallet.html" target="_blank">Archer's Sallet</a> to a more authentic shape, that improved my meagre welding skills using the gassless MIG welder I'd been given last Christmas.<br />There were 3 English longbows, Yew, a boo/hickory/Yew and a Yew one with a nice protruding character knot near one tip.<br />The Year wound down with two Yew primitives, the first having a lovely feature knot hole through the upper limb (another thing from my to-do list) </p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEg3hUm2FWLMW12bN7-UALZVSrgu_BPUr2f4nYEAavg8x-WqNPpwYeJbKu3Um73S7-NfpFORfUZJsQKSRIlgnHt68F08hCyhHmC6hCny7FZXTwm-v2zsKPRDfNumhUdxfSyAPH8y2JHSd21Z2m9EWd1zDpZpTI5WLFSYYPb7BuW2p6gR7rDSJfF2QLjlGA" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img alt="" data-original-height="1600" data-original-width="1062" height="240" src="https://blogger.googleusercontent.com/img/a/AVvXsEg3hUm2FWLMW12bN7-UALZVSrgu_BPUr2f4nYEAavg8x-WqNPpwYeJbKu3Um73S7-NfpFORfUZJsQKSRIlgnHt68F08hCyhHmC6hCny7FZXTwm-v2zsKPRDfNumhUdxfSyAPH8y2JHSd21Z2m9EWd1zDpZpTI5WLFSYYPb7BuW2p6gR7rDSJfF2QLjlGA" width="159" /></a></div>That is probably my most accomplished bow, clean and simple and elegant with no fancy leather grip, decoration or bells and whistles.<p></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEjoczR4Ys_4k5a9Hc90hVPOZiXLzvy05NLYKgJDXkTO5I3hYbXvbbZRCq4_m2CYrIQrgP4EowfTUGe1mjpkky-eN9UOJjwfQyDR3x7TeR8d3clKjM0Dtdg7RA8iL6CtMjMCjCq2fjUf87wKrznieJjwODBSG4oyoB3D9QJO6iWgMl-St4jFlohsWbGyTA" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img alt="" data-original-height="1054" data-original-width="1600" height="211" src="https://blogger.googleusercontent.com/img/a/AVvXsEjoczR4Ys_4k5a9Hc90hVPOZiXLzvy05NLYKgJDXkTO5I3hYbXvbbZRCq4_m2CYrIQrgP4EowfTUGe1mjpkky-eN9UOJjwfQyDR3x7TeR8d3clKjM0Dtdg7RA8iL6CtMjMCjCq2fjUf87wKrznieJjwODBSG4oyoB3D9QJO6iWgMl-St4jFlohsWbGyTA" width="320" /></a></div><br />My final Yew primitive was cut from the Yew in our back garden and is by comparison an ugly agricultural thing, but it was a challenge and it shoots well enough. <br /><div><br />This blog will still be ticking over, but most of my work will be on my Youtube chanel (Del Cat), where the first project for next year will be a 120# self Yew warbow for my mate JT for roving.</div><div><br />That's about it for the year. I wish you all a happy New Year, and lets hope 2023 brings change for the better in the world.<br />There are some rays of hope on the horizon, the tantalising promise of nuclear fusion... mind those of you who are as old as me will remember the promises of the 1950's ... Nuclear energy that will be so cheap, it won't be worth charging for it!<br />May all you arrows fly true and may your to-do list grow shorter!</div><div><br /><br /><p></p></div>Derekhttp://www.blogger.com/profile/07654835987876553254noreply@blogger.com0tag:blogger.com,1999:blog-5493681473159888383.post-82032447337592506712022-12-13T15:23:00.003+00:002022-12-13T15:23:56.656+00:00Snow<p></p><div class="separator" style="clear: both; text-align: center;"><br /><a href="https://blogger.googleusercontent.com/img/a/AVvXsEgj_mcMPi0XxN9Xw5V8oz8FKbffpRGEksvAivGg_44lMPKrHKjR_Kf99LTuWzXoJ2Dl23bl8ryidcErQuk5-saeGQSphHln5QbgCFnGG_LsO9PlE0D7six1gXuxrhUDGdQWWlkOW2fiVrJqaSfOI-t_yP96OmkHf8HlMiMmx_D7S_NSEL37yZ2jajxWRw" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img alt="" data-original-height="3864" data-original-width="5152" height="240" src="https://blogger.googleusercontent.com/img/a/AVvXsEgj_mcMPi0XxN9Xw5V8oz8FKbffpRGEksvAivGg_44lMPKrHKjR_Kf99LTuWzXoJ2Dl23bl8ryidcErQuk5-saeGQSphHln5QbgCFnGG_LsO9PlE0D7six1gXuxrhUDGdQWWlkOW2fiVrJqaSfOI-t_yP96OmkHf8HlMiMmx_D7S_NSEL37yZ2jajxWRw" width="320" /></a></div> We had about 4" of snow and it's been B cold. I was going a bit stir crazy stuck indoors... well not really stuck, I did go out to clear the path and make a snow man (My missus added eyes and a smile out of raisins). Anyhow, I had a bit of a tidy in the garage, which wasn't too cold as it gets some heat from the central heating pipes that run through it. Some of my staves had been taken down from the shelf to allow be to drill a big hole into the kitchen to vent the cooker hood to the outside world (via the garage). Two staves were large halves of a log about 4 1/2" diameter. I decided to tidy one half up, but was dissapointed with the results... it seemed to be full of checks and splits and streaks of black... maybe it'll look better as it's gradually reduced to bow dimensions. the other half looked better, but by the the bandsaw blade had snapped and I was ready for a cuppa.
