prop twist

[bassman]

I quit fighting extreme prop twist. I wack off the straightest part of the stave ,and build the bow.It is the reason I have built so many short bows over the years.Good info on how to straighten prop twist above. I  take the bow down to floor tiller, and put on a form when working with moderate twist. With heat ,and clamps get the stave to conform to the form.Lining the tips with the riser ,and taking the twist out as you go. You may have to repeat the process to get it to were you are satisfied with the end result by making minor adjustments here, and their.

I reduced the stave some over the weekend. I was able to remove some of the twist in one limb. There is a long way to go though. This is going to be an experiment to see just how much a stave can be manipulated with heat.

I think it is going to take a lot of steam and patience. To give you an idea of how bad the twist is, in the pic attached the handle section is in the vise with the belly facing up.

Jim, get it down closer to bow stage. It's easier to manipulate the wood with heat when there is less wood. And, you can make corrections more that once during the building process.

Yeah it was a struggle to get the limb to in twist. It isn't even close to floor tiller yet. It also has a bend right at one fade. I should be able to manipulate the handle and get a lot of it out.

Yep, you are way too thick, I would go to 5/8" or 3/4", plenty of wood to make any poundage you want.

I haven't untwisted many staves with a 90 degree twist like that one. If I remember right I respliced all of them and then did the heat thing.

I have already narrowed the handle section some so splicing is probably out. If they just wont take then I will make two kids bows for some of my grandkids.

Please keep on! Very interesting for my few twisted OO staves.
Pics from steaming would be very helpful, too.
wish you luck

I decided to make two kids bows out of it for Christmas. My twin grandsons will be better served this way than me with my experiment.

This makes me wonder how hard it would be to build a bow with a twist like that.... But instead of try to take the twist out, make the limbs rotate into the correct alignment as they are drawn back.

The grand son's will love that.

I've wondered this also.
