Title: Noob Bowyer questions on limb twist and heating
Post by: Jakesnyder on July 24, 2018, 04:59:28 am
Just like the title says I'm wonder if all limb twist needs to be removed when making a bow or if a little bit is acceptable? I know both tips have to align with the center of the handle but should the goal be to get the bow  as flat as possible?
And another question is dry heat or steam? Does it depend on what type of wood I'm using?
Thanks!

A little bit of limb twist is acceptable.

You can use both types of heating, but I'd recommend steaming the wood. Its definitely the safer option, and I've had better results with it.

For a straight long bow you can get away with a considerable amount of twist. If your planning on a static recurve it will need to be removed to keep string aligned.

For a selfbow a bit of twist is OK. With a lam-bow, not so much. I've used dry heat successfully to help remove twist in selfbows but with a glue up the glue would matter whether you can use heat or not.

If you are going to remove some of the twist why not remove it all. I have found removing twist is the easiest of all the other stave corrections. I use dry heat for removing twist.

Simson is someone to take inspiration from but if you try to emulate it it could be really frustrating  ;)

Eric, in that picture, how much of the limb did you heat?

I sight down the limb and only heat correct from where the twist starts. It is usually mid limb and out or less, a few times it would take a double correction as the limb might twist to the right and left in the same limb.
