Can I unglue this with heat?

[BABAR]

This is 1/32 ply glued to 1/8 balsa.

Problem with watching football while building (at least Air Force won, games don’t get much closer or crazier than that!)

I don’t have a heat gun, can I bake this in the oven at 100 degrees centigrade to weaken the glue?

Do Over.... Gorilla Wood Glue = Indestructible

Agree with lakerroadster, do over.
If it was just a surface spill, one of these methods might've worked: https://gluethings.com/what-dissolves-gorilla-glue/
But since the two surfaces are now bonded tightly together, you're pretty much "stuck" with the result.

No, the heat required to destroy polyurethane glue would almost certainly destroy the wood also. Plus the chemicals released by the decomposition of the glue might contaminate your oven. You might be able to salvage one wood piece by cutting the other piece away but at least one of the wood pieces will almost certainly be lost.

Thanks gentlemen. Saved me from futile time wasting.

I think I may brush up on my surgical skills.

Will follow this up on scratch build post.

Guys, it’s Gorilla *wood* glue. It’s PVA, not polyurethane.

Nonetheless, I would also call it a do-over. Although you could try baking it and see what happens, if you’re planning to redo it anyway.

You could try "Dremeling" away the least valuable part.

You might be able to soften the glue with water, but that likely would screw up the parts.

My advice is try and cut the small piece off the larger piece. I'd try using a small block plane set to take a very thin cut. You may want to try sanding carefully to get the last few mils (.001 in) if you try this approach and need a smooth surface on the surviving part.

It's 20 cents worth of material, chuck it and remake... have another $12 beer to wash down your chips...

Completely agree with you on material cost. It was also however at least an hour or two of time.

I think my surgical “brakoplasty” was inelegant but effective solution. With added benefit it is exactly where I need to drill a retention band hole anyway, so should be super strong now.

I kind of feel like an old 7 Up commercial,

The “UnGlue Thread”!
