How to proceed?
« on: August 14, 2018, 07:11:47 am »
I was just about ready to brace this bow when the backing on one limb de-lamed to about 6" from the fade. I know why this happened... I ran out of epoxy and the limb in question got less than it's fair share.

Nothing broke, so I'm thinking I can just glue up that limb again. However, here's my question... Do I glue in the original amount of reflex or do I match it to the amount that's currently in the intact limb?

What kind of epoxy did you use. You may be able to heat the belly enough to make the glue release, clean up the glue surfaces and re-glue.
 I'd say either you didn't add enough glue to that area or you clamped it too tight and starved the joint of glue.

I used Smooth On. I'm almost 100% sure it was lack of glue.

I really like the looks of that bow. 

That's a tricky one to answer.  At initial glue up, the glue is holding shear forces with the original thickness of the wood.  As wood is removed, there's less resistance from the wood but the forces in the glue remain the same, and the limbs "gain" more reflex.  So reflexing to the original amount won't hold the same glue forces since the wood is now thinner.  If you can't re-glue both limbs at once like Pat is suggesting, I would try and match the other limb with a little more added in for spring back.  It's probably your best bet.

I like that Ben and if DC does too that's good enough for me. I'll let you know what I decide to do.  :OK

Well I decided not to remove the whole backing cause the joint is very good right up to where I ran out of epoxy. I cut a new single-limb caul identical to the opposite limb w/ a bit more reflex to account for springback and glued her up once again.

Fingers crossed...

Always mix too much glue :), it's a little late for that advice isn't it. ;D

Hilarious Don  ::)  lol

Sure hope so Ed. I've screwed up attempting this style more times than I care to admit.  O:)

Don't worry!  I can probably find a way to screw up a sapling full round, braced without any scraping, planing, Sanding, or bark  removal, or finish!  Good luck with the re-glue process!
