So I have this awesome bow that has about 1" of reflex. After I shoot the bow for an hour or so, it goes to about 1.5" of string follow. When I check it the next day, the reflex is back at 1". Is this normal? What's going on here?
-
wood is probably too wet still.
-
It is very common but it doesn't matter if it comes back in 1 minute it is still set. I have a bow right now that I am very frustrated with. Still a very good shooter but the bow took almost no set, about 1.2" but when I draw it to full draw the first time it will read 58# second draw and all draws after that it will read 53#. Let it sit for a few hours it does the same thing.

It has been seasoned for 2.5yrs and it had one heat-treating session.

How much reflex did it have before tillering?

It had around 1.5" of reflex before tillering

Have you heat treated it yet steve?

Maybe I should heat-treat again...just to get some more moisture out of it?

Yep, I thought it might still have some moisture so let it sit for a couple of months. The poundage went up a little but still has the weight loss. The bow is overbuilt and plenty wide and tiller looks good. Holds about 1 3/4" reflex and settles in at about 2". It is a very good shooter but I think it would be better without the weight loss. No reversing it now.

Some wood bows do just behave like a sinewed bow. The combination of the back pulling the belly back and the belly cells slowly expanding slightly over time.
And that happens even if the wood is dry enough. I find some Elm is frequently like this. Kind of a hard but rubbery texture to it.
Composite bows actually do this to a large degree. I wouldn't worry about it. Materials that were once living behave like living things. They get tired and they recover.

Lots of bows behave that way, some of mine do, it is just wood doing what wood does. My wood is seasoned 10 or more years, kept in a moisture controlled environment. All of my bows are osage, on long shooting sessions I can tell a few lose a little punch with the first shots being much faster than the last. I have other bows that never slow down or gain and lose set overnight, wood is wood.

Eric I tend to agree with ya. The great ones come 1or2 in a hundred. The rest are just really good bows. Except for the occasional failure . Yes 230 latter there is still a failure on occasion . :BB

Hi Badger, out of curiosity is the bow you speak of sinew backed?
-
That's 3 total inches of set. That's a lot. Sounds too wet to me also. 2.5 years of unaided drying/seasoning may not be enough.
But then again heat treating a wet stave would cause drying cracks.
Is the design (too short, too narrow for draw length) the culprit?
