Heat treating Yew

[BrokenArrow]

I am going to re-curve the tips of a yew flatbow.
How long should I leave the wood in the clamped position?

Thanks

Until it's cool to the touch. more than that is unnecessary, in my opinion. Honestly you could probably take it out while it's still warm (not hot) and it wouldn't matter but you may as well be patient and wait til it's cool.

I like to be sure the wood is completely cooled, inside and out. I usually leave heat treated and heat manipulated wood clamped over night. I'd rather be patient and not risk having the curve pull out.

I like to steam or boil my curves in yew. I'll heat gun it right after and leave it till it's cool to the touch. Overnight is probably better though

      Yew is about the only wood I never heat treat. I use steam for the curves and like to leave them overnight. Anything I do with try heat I take out of the clamps when still slightly warm if I feel like it.

Like others, I steam or boil the tips, then clamp. Leave clamped for a bit, then dry heat temper the belly side of the bend pretty good with a heat gun.  This helps keep the curve from pulling out in yew.

All of this goes much better if you have your limb tips down to a reasonable amount before attempting the bend. Trying to bend too much wood is where I got into trouble early on, and I see a lot of others make that same mistake.
