Waiting after tempering, how long?
« on: December 10, 2013, 11:36:28 am »
 I know its been posted before by a few people, but I would like to get more peoples opinion.

After a good heat tempering of the belly, how long before you take the bow out of the reflexed position? whether it be a form or strung backwards with a piece of wood raising the string. Relative humidity is the main factor for leaving it in position, after cooling of course, but are there any other factors in play?

At the moment I am working a shagbark hickory recurve, but any info on any wood in this regard would be appreciated.

I usually just leave them on the form until they are good and cool,sometimes over night,but after that I give them several days/ 3 or 4 at least before I start bending them again. :)

Dang... I hate waiting. Especially after working like a mad man for hours in a row then it all just stops. good thing I have more bows started!

I'm with Pappy. I let tempered bows stay on the form over night then give them 3 or 4 days to rehydrate before stressing them. It pays to have 2 or 3 bows going at once to prevent impatience from calling in Murphy's law.  ;)

It might not be necessary, but if it is a piece of whitewood, and I temper it pretty thoroughly, then I let it rest for 2-3 weeks.   This results in lots of bows in the works at any given time.   :)
I think 3-4 days is plenty for osage.  It likes heat!

It may just be that I'm ignorant of what better results I might have with more patience, ...but I've always just figured cool to touch was kewl to work on and kuul to remove from the caul.  Maybe I drank too much koolaide... 

If the metered MC is back to what it was prior to tempering, is more moisture change still going on?

After a simple heat and move scenario, Im sure cool to the touch is fine. But a full blown temper may warrant a bit more wait time than just cool to the touch.

I even give my heat to bend/straighten over night to insure that the internal temp of the wood is cool too. The surface temp might feel cool but internally it could still be hot(warm).

NeoLithicDude - Please listen to these guys with years of experience and NOT me.  It would be little surprize that I need to be more patient in all things bowering.

This is the bow I am working on now. I treated it yesterday morning and I was planning on leaving it like this for another day but now I am thinking a day or two on top of that from your guys' advise.
Is there benefit from removing the string and dowel? I had figured leaving it would not hurt if not help the bow... now that I have typed it I realize I have no evidence or reason to think that

When you're waiting for a bow like this to re-hydrate, would it be counter productive to give it a little spritz of water?
