Ipe is a pretty oily wood. I would use acetone to degrease it. Others might have a better solution(Pun intended)

Use acetone or naptha. Do it right before you glue. The oils return to the surface fairly quickly. if you degrease it like the day before it will have no effect. If you dont clean it good you can pull the pieces apart easily if you use tite bond3.

Should the back be sanded with fine sandpaper after the the acetone dries? And would Lacquer thinner from a body shop work?( I work in a body shop)

If using tb3 I would sand it dead flat with 50 or 80 grit then use the acetone. You dont have to wait more than 2 minutes for the acetone to flash off. no fine sandpaper and no sanding after you clean it.

I've had a couple of problems with glueing ipe, I read on the internet (can't remember which site) that cellulose thinner works for degreasing it but my bamboo backing just popped off straight out of the form.

The glue I'm using is called Resintite (like the cascamite that bowyers apparently used to use), I've ordered some Urac and I've seen bows made with this glue that haven't been degreased at all that seem to work fine but should I be safe and do it anyway? And does the cellulose thinner actually work?

Thanks for your help

I glued on 2 staves without degreasing, and both are doing fine, seems to hold very firmly. one if them is the bbi pyramid I posted here.

but degreasing is really smart, acetone will do the job perfectly.

I think it depends on the board. Some is really oily and you can peal the glue right off if you dont clean it.

Thanks, does anyone know where to find acetone in England? It's nail polish remover right? Would they have it in B&Q?

Again, thanks for the help

Muina, acetone is also used for paint thinning and cleanup. Try any local hardware store and you should find some on the shelf right next to the mineral spirits and other paint thinner.

I tried in all the hardware stores near me, none of them had it and only one of them had heard of it. I'll see if I can get some off the net unless anyone can advise me? I'm in the North of England (Hull) so if anyone knows of anywhere nearby that sells it.

Thanks

P.S. Could anyone tell me anywhere to buy Urac 185 in England? I've had to order some from MissouriTrading and I'm still waiting for their e-mail about a different delivery price.
