Update on 120# yew warbow - I don't like to complain, but...
Marc St Louis:
It's obviously not stretching but slipping someplace, if you have loops then your loops are slipping
WillS:
Yep you must be right!
Well I've made one more double loop Flemish, keeping everything as tight as possible, so I'll see how that goes and if there's no improvement I'll move onto endless loop.

They say a proper glue joint is stronger than the original wood. Si I wouldnt sweat the split. I would wear a helmet though...

What I have found with the bowyers knots on both ends, is the lower limb one does not slip because it is pushed tight against the nock and is then left alone but the upper limb knot tends to slip and needs regular adjustment. This is because it is constantly tightened and loosened when stringing the bow. I have found that you can lessen this effect by keeping the wrap loops of the knot close together and use five of them, they end up looking like a hangmans noose. This makes the knot easier to loosen when de-stringing because by twisting the knot, this bulky part lifts out of the side nock slot and you can then pull the loop down the limb, opening it up!
I have a theory that perhaps a bowyers knot may not have been used on the upper limb, even though they had side nocks.
Perhaps they used a system that is a self tightening loop instead of self tightening knot (bowyers knot) or a fixed loop.
In one of the Bowyers Bibles it shows a string with a very small loop ( probably formed as you would with an endless string) and then the string is passed through it. I think native Americans may have used it!
This in effect is a self tightening loop and gives the advantages of both loops and bowyers knots!
The small loop which is bulkier sits on the outside of the side nock the same as with bowyers knots. The advantage of this type of loop is it is easier to get on and off (like a fixed loop), it wont slip ( like a bowers knot) and it is self tightening (which is needed to spread the strain of a heavy bow string all around the horn nock)
I shall make one and try it out soon and pass on the results
WillS:
That would be good, always worth trying stuff out I guess.
I just asked Michael Heinz what he uses as he's made plenty of heavy warbows, and he says he uses FF+ 16 strands for bows up to 120# with two Flemish laid in loops, so there shouldn't be any problem with that. I must be making the strings wrong for them to slip constantly the way they seem to be doing.
It probably needs somebody used to using Flemish loops on warbows to see what I'm doing and tell me what's going wrong, but until I can find somebody I'll have to try endless loops I suppose.
