So I've been brainstorming how to allow a roughed out bow to gain in reflex while drying but not allow it to warp sideways, throwing off the string alignment. Here's what I came up with...
I secured the stave to a thin aluminum bar that bends easily front to back, but not side to side. Think this will work?
-
It may help but I'm thinkin' that as it reflexes it will be free to twist which may throw your alginment out.
-
Twist might be an issue. Why not get a couple 2x6's and make some simple reflex cauls. Clamp some roughed out green bows to it and see how that works.
-
Yeah, I am worried about the twist. I like the reflex caul idea, I just wanted to see what a "natural" reflexing-while-drying scenario would yield.
-
clamping it to a caul seems like a good idea (=)

Probably more reflex on one limb than the other, with a side of twist.

I think upstate if you used C clamps at the places you used duct tape it could'nt laterally warp as bad.Just a thought.Might not be right.
I used to do that drying into a reflex a lot with elm years ago.Was'nt a natural reflex though.It was induced.On a 2" by 4".It still pulled out through tillering.
A person can't get it better with natural reflex.If it pulls out through tillering.I've seen it come back with a heat treatment on it's own.

wanting to leave it natural has some merit. Some staves go into reflex or deflex immediately upon splitting because there is tension or compression wood differences inside the stave itself. Preserving this natural warpage might be useful.
On the other hand, shape changing during drying most likely comes from drying rate differences. Although it happens naturally, it is part of the death process. perhaps slower drying can minimize warpage and cell damage?
-
Adding reflex while a stave is drying works but not as well as adding it later with heat or steam. IMO

This is what I was thinking Ed. After I roughed out the stave, I floor tillered it just enough to get an even bend/thickness taper. At this point, the natural reflex seemed pretty balanced and I was hoping that If I could keep it from warping laterally, and keep the twisting to a minimum, any additional natural reflex the bow gained while drying would be more apt to keep it.
Every time I've clamped reflex into a green roughed out bow it has pulled out eventually.
Pat, I agree that reflex steamed or heated in after a bow's dry works way better than while drying.
Willie, interesting points you've made for sure.
