Crossbow Prod Details

One of my online friends asked me about the poundage obtainable from some 20mm wide glass laminated crossbow prod of say 36" long
Of course it depends on plenty of factors... is it a one piece prod or individual limbs which have several advantages but some disadvantages.
Individual limbs can be adjusted to angle back or forward with tapered shims and will allow a centre shot, the downside however is that you sacrifice some working limb length in the mounting clamps.

Anyway I said I'd provide some pics and dimensions which should allow him to do some back of an envelope calculations to get some sort of ball part figure.
One thing to note is the nock which has a substantial horn overlay and is bound with carbon fibre soaked in epoxy, this is needed to stop the string cutting into the limb tip and splitting down it.
Dimensions:-
Overall nock to nock 37.5"
width x thickness at root of limb 44 x 8.3mm
    "              "        "       mid limb 37.5 x 6.8mm
    "              "        "       tip            25.6 x 5.6mm
Brace height 3" power stroke 12" draw weight ~90#

20mm wide glass seems a bit narrow, sow maybe two pieces could be used side by side to give 40mm , obviously that's easier to say than to do as glue ups are notoriously slippery, but maybe two bits could be joined edge to edge with a few tiny spots of epoxy to hold them together?

All this sharing of info seems to have increased during the Covid19 lockdown as people are communicating more. I did a You tube video for one bloke giving hime more details of my belt drive conversion on my mini mill.
Any how keep busy one and all and try to stay safe and sane!
