TBIII on the glue up. Not sure there in anything to do but saw of as much of the hickory as possable then sand down to the ipe.

I have steamed off a hickory back before that was glued withTBIII, it came off easy. Ipe needs some serious wiping with lots of acetone, untill the yellow/brown oil stops coming off on the rag, then glue immediately.before it oozes back out....,its oily stuff...

 Use your heat gun, Tightbond will let go pretty easy with heat. Especially with Ipe.

I will give it a go with the heat gun tomorrow night. My boss is coming over & using my shop for a project so I can be in the corner trying to get the hickory off.

Great suggestions fellas. Really appreciate all the help.

Had some second thought about the heat gun. I am thinking about steam. Less chance of fire and I need to build a steam setup for the Hackberry project I have going.

bevan, just use your heat gun
just make sure there is no wood shavings/saw dust in the direct area your working
once you get that backing heted upto about 150* (internal temp)
that suckker will come right off no problems

I'll try Tim, but if I torch my NEW shop, I will never hear the end of it.   :P
I assume I need to apply the heat to backing side?

Tim,
Since it is a hickory backing I am heating, should I put a piece of meat on it and handle supper at the same time  ;D

I'm surprised at that.  I've done several and haven't seen that happen.  Was that backing strip sanded smooth on both sides before the glue up?  I always sand the things out smoothly and lightly sand off the sides of the strip before I do any tillering.  Good luck, hope it works out for you.

I had run the backing through my planner then gave it a good sanding then cleaned both the backing and ipe being used for the belly. Then glued with TBIII. I think the original thought I had is the correct one. This is heartwood hickory and is much more 'brittle' than the hickory I am used to using. When I questioned it to the supplier I got it from, I was given the 'we have been using this for years and never had an issue' song and dance. Well lesson learned, not using ANY of their products again.

Hmm.  I don't know.  I've made several bows with half sap/half heart wood and didn't have that happen.  It's odd, I think.
