Title: Acetone on lams. To be or not to be.
Post by: barley40 on May 01, 2011, 06:26:00 PM
Binghams says not. Brush off with a stiff brush. However I've noticed many bowyers do wipe them with it before glue up. What say you?

I don't and never had a problem.  However, I did use cocobola for a longbow riser rencently and I did wipe that well with acetone prior to glue up.  In a wood like cocobola, you can actually feel the oils of the wood on the surface.  If you're working with oily woods, it can't hurt.

I have done it both ways with success.  It seems the opinions kind of swing back and forth.  I still keep the acetone around but only use it on things that are really dirty.  I feel a fresh sanded surface and a good stiff brush is the best.

Grit and oil make adhesion a problem, any oily wood I wipe down for sure and sometimes wipe everything. Acetone has no adverse effects with urac or smooth on don't know about anything else.

Remember, folks. Acetone CAN bring more oil to the surface. Fresh sanded is the best  ;)

I don't apply acetone to any surface to be glued with smooth on.  Just sand prior to glueup.

I agree with the fresh sanding. When doing oily riser or oily veneers I sand close and then I can hit them once taking them to final diminsion immediately before layup. I also believe that acetone will actually bring oil to the surface. I have never had a delamination with the immediate sanding procedure. I did have a bocate veneer delaminate that I had wiped with acetone. Whether or not the acetone was the culprit I don't know. I do know that I do not like to use any of the oily woods as veneers unless I grind them fresh with a fairly rough grit and grind them pretty thin. Like .020 or less.

God bless you all, Steve

I rarely use acetone, instead I use denatured alcohol for most  my cleaning because the fumes are not as toxic,  I used the denatured alcohol on about half the laminated bows I have  built without any problems.  However, I have only built 22 laminated bows, so  my experience is much less then others.

I've always used acetone on every lam.  Haven't had a delam yet! Knock on wood!
