String length
« on: July 21, 2018, 05:48:46 pm »
For a 66-68" bow how much do you have to change the string length to change the brace height by an inch? I think it will be easier on my hands to move the nock rather than make another string. :)

Twist it up 10 times and check. An inch is a pretty good bit to make up by twisting though. Is this a Flemish twist string?

Yes it's Flemish. The string is too short so I was going to move the nocks in. But you're right. If I twist it up 10 turns and measure the change in string length and then measure the change in brace height it will give me the info I need to sort it out.
Thanks

Yup, but I think it will be one of those gradually changing things where every little thing changes it some.

If you twist it up 10 times it will get even shorter, make another string. Cutting new nocks will up the poundage and may throw the tiller off.

I would make another but it's three hours since I made it and my hands still hurt. Take my advice, don't get old :D :D

I am 70, I don't like making strings but sometimes you have to.

I have arthritic hands and bad carpal tunnel problems in my hands from 20 years of working down osage staves with drawknives. I worked a lot in my shop this afternoon and will have to wear my wrist braces when I go to bed tonight or my hands will go painfully numb and keep me awake.

Make continuous loop strings, relatively quick and easy, served loops, right length every time if you use and long string and Del's patent ;) adjuster first to get the right length.

70 here too, DC. Thank God. Are you twisting the whole string or just the loops and down to just beyond the tag ends which is what I do? Jawge

You can make strings with a timber hitch on one end.

You win Eric. I'm just a wuss. I could have it way worse ;D ;D
You know, it might be time to convert to continuous. Way easier on the hands :) I just like the look of Flemish.
Just twisting the ends as little as I can :)
I've never had good luck with timber hitches. Even with all the fixes they still seem to slip on FF

I use 9 strands made into 3 bundles to make a rope ,spliced in a loop.this is a old b55 string that I didn't bother to serve.all the twisting is done with a cordless drill,something I came up with.

Not well. Whether the string is still settling in or what but I would add 10 twists and the BH would go up and then over 15 min go back to where it was. I started at almost 0 twists so maybe not much happens in the first 20 twists. I'll let it soak for a while and see.
