mikekeswick:
It is useful to brace these biggies early to see the true shape.
Use a 20 strand tillering string. Use a lighter string once it is tillered to full draw.

DC:
When you make a new string even with supposed non-stretching string it has to settle in(for lack of a better term). I think what happens is the twists tighten up and the wax gets squeezed out. This takes maybe an hour or so(your results may vary). If you can pre-stretch do so. Also the longer you make the tails and the farther down the string you twist the more it will "stretch". I always thought my loops were slipping so I kept making the tails longer and longer. The problem got worse and worse. Finally someone on here convinced me that I only need about 7" to make a loop. Now they only "stretch" a little. Takes about a half hour to settle right down. All this is for a Flemish twist string. I've never used 452x but I think it's the same stuff as FF.

Badger:
JN, you can measure the current draw weight of your bow while it is still on the long string. It will read just about the same poundage with a long string as it would read if it were braced. So if it says 120#@24" with your string hanging down loose 6" it will still read about 120#@24" when you brace it. I know that sounds counter intuitive but it is pretty accurate.

JNystrom:
Thanks for the advice's again!
I was just thinking what was the ratio for long string vs short string. I remember Del talked about it in his videos, just couldn't remember how was it exactly.
Anyway, now i got it braced, 20 strand, little bit stretching and little bit scraping did the job. When i first time tried to brace it, it must have been somewhere around 120#@20", so maybe 180#@30?? No wonder the strings stretch...

Here it is 100#@20". I feel the tiller is close to spot on. 5" brace height. My earlier attempt was to get as much poundage of the stave as i could and i can feel the hunger growing... The profile is quite nice for a white wood bow (still 40x31mm in the handle) and with heat treating, i could bring the poundage up another 10lb. What do you think of achievable goal?

ps. It weights 33 oz atm.

JNystrom:
Well... It broke. 1" higher brace height and 105#@21".
Apparently it had extreme spiraling growth. It's quite common for rowan, but not this much. That spot left next to handle wasn't bending way too much anymore, but that is where it broke.
No worries, i got very nice stash of wych elm staves... Already got one coming.
