Title: backed wrong side!!
Post by: chasing crow on January 09, 2021, 01:53:29 pm
Has anyone been stupid enough to back the wrong side of a limb? I used Gorilla Wood Glue and burlap. Any removal suggestions?

Heat might work. Contact Gorilla Glue tech support. They will give you the answer. That's how I found out about TBIII breaking down at 150 degrees.

Good advice Pat. Making my daughter's boyfriend a hunting bow after a 4-5 year lay-off from building. I even told myself to watch what side I backed the day before I actually screwed it up! Getting old I guess.

Sand it off with coarse paper.  What sort of belly does this bow have that no hints were detected that it was the wrong side?

4" grider with a sanding disc on it. Wood/power planner, 6ft belt sander.

Since nobody is giving you grief, I will. 

I want some of what you were smoking! 

That is all I can muster, as I haven't been doing this long enough to make that mistake yet.  I don't think I will make that mistake, but I also know that I've never made a mistake that I thought I would make.

How is it possible to back wrong side :)? And if its done then why is it wrong side. I have made good shooters with every direction of belly wood grain. I would like to see pic.

BJ, that just makes areal nice bow for a person who shoots from that side!  Send me in, Coach :BB (SH) (lol)!  It is possible to correct that slight error, as I did (with help) on "Transdex" the bow I was gifted by Badger.  Still shoots pretty good!

I removed a backing of cotton fabric and TBIII by carefully using my belt sander to get the bulk of it, then a block and coarse paper to finish. It certainly will provide penance for your mistake as it is a tedious job that requires care lest you wreck a bow in the making.

Don't feel bad, Chasing Crow, we have all done things like this even if some don't want to admit it. On my first recurve I realized afterwards that one recurve turned up, one turned down. I think it is that as new builders we get in a hurry and are not concentrating or are distracted. As long as we learn from our mistakes we are ahead of the game.  :OK

Imagine that? Good deal. Always a fix out there somewhere.

I just read me your kind replies. Yes, not too swift. But it is the first bow I've built blindfolded! Cheers!

Just put a backing on back and retiller.

I cut the string nocks on the wrong side once. You are not alone. On the plus side, it will be easy to remove with a little heat, the glue will weaken and the burlap will pull right off.

Ya don't feel bad, I have made some pretty big boo boos myself, ??? if fact more time than I care to mention, once cut the nocks in backwards, or maybe twice. :-\ You can probably sand it off or maybe a scrapper. :) Heck you could leave it on and back the other side also. :)

They say "Gorilla Wood Glue is very heat resistant. Once cured, it is safe to heat up to 150°F." That is much lower than my normal heat treating temperature of 150°C (302°F) for 30 minutes. But we need to be careful with fumes or smoke.

I haven't backed the wrong side......yet, but I have twice cut the nock grooves angled the wrong way by mixing up the belly and the back while the bow was in the vice.... (lol)

not sure how that happens ,but yes a heat gun will break down gorilla glue . I have used heat to break down gorilla glue before... works like a charm.... gut

Don't feel badly.

I strung a board bow backwards. It was a piece of red oak I inherited. It was a bow for my Kumbaro's (:)) son. I've cut nocks backwards. I forgot to compensate for knot on an osage stave and broke it. I've probably done lots of other things.
