This shows how a bow is worked back by removing wood and pulling it to the same draw weight, each time it comes back a bit further...
If you are not heartily sick of putting it up on the tiller, exercising it but pulling it up to draw weight a few times and studying it,. Then you aren't doing it often enough!
Dunno if you can see but I've drawn a straight pencil line on each limb to help me see the overall curve of the limbs without the knots and dips distracting my eye.
It looks pretty good if you hold a CD up to the pic. If you compare with the previous pic you'll see the differences are pretty subtle, the right limb has a slightly fuller curve and the tips are more level Mind I can't guarantee the bow started in the same position for both shots, and the brace height has been increased a little.
I'm still a bit nervy as the bow is very knotty and it's getting to the point where it can easilly go bang. Just for info, they usually go bang just when you breathe a sigh of relief and thing Ah, nearly there! At about 26" draw!
My visitors came over and we had a fun morning, I was showing how to reduce sapwood and layout billets. We had a go with a load of my bows including the Chinese Repeater. I shot one of his bows, a Boo backed Lemonwood bow, it was a nice bow and had been drawn to a full 32" which was pretty impressive for a relatively short bow. It was a sensible cross section a shallow D, I suggested the 'boo could have been a tad thinner and the nocks a bit slimmer. Loosing weight from the tips would give a more Warbow shape and would boost the speed a whisker. The 'boo backing was particularly handsome as the surface of it was slightly concave in places giving a really interesting look. He brought some knives he'd made too, one looked really handy as working knife.
He was more into laminates and backed bows and his dad had a decent woodworking workshop which must be really handy.
It was great to talk to people who understood wood and were into bows.
I gave him 3 pairs of billets, one really skinny and scruffy, one pair matched but rather short and skinny, the final pair had much more wood, but each had a slight waggle which could maybe be ignored and laid out straight at a pinch or laid out following the waggle giving a symmetrical bow with some character, the tips and centre lining up nicely. There should be a bow in there and it will certainly give some practise splicing billets and working with Yew.
A couple of bottles of wine were a very welcomed swap!
Sunday lunch and I've just tried my Wilko's "Hoppy Copper Bitter" to go with it.
It's only taken about 3 weeks to be ready.
It's excellent, much lighter than the stout, nicely bitter, just right for Summer drinking... result!
