Alcohol and CA

>If I remember some of the past posts correctly, there have been some problems with glue blocks held with CA after soaking. I held off using any CA until after the soaking just to be safe.

>Thanks, Barbara. Me and the WC search engine don't get along too well and I couldn't find anything. I had to either use the CA during roughing or trash the piece. Wasn't sure it was going to hold together after the CA, but I did manage to finish the roughing. It's in alcohol now so I guess I will be able to answer my own question on a couple of weeks!

It should be OK

>Hi Carole,

I often use CA glue on lose knots during rough out. I also stiffen tenons on punky wood with CA glue. So far the glue has survived the alcohol soaking. I have heard of only a few times when CA glue seems to have failed during the soaking process and in each case it was on a glue block. If it is Bradford pear then disregard my comments.

>LOL Thanks, Dave. It's not Bradford, but Mulberry which seems to be almost as "cracky." Will let you know if the CA holds up.

>Carole, I've done quite a bit of DNA soaking since I read about on this site. My guess is that you'll be alright. I have noticed a change in texture of the CA when it comes out of the DNA but once the bowl dries it seems to be fine. Oscar

>I use CA on glue blocks for rough turing, then I dunk in DNA. Never had a problem yet. The CA does turn white but turns off.

>There is no simple answer. It depends on whether the CA is cured or not. If the CA has been allowed to a TOTAL cure, it will not be soluble in alcohol. Anything less than that could be a problem whether the wood is soaked in the alcohol or it comes as the solvent for a shellac. Total cure takes 24-hours. This time is reduced by heat generated from sanding, such as when finishing a pen.

Using an accelerator can be a problem because it can arrest the CA in a partial cure on the surface of the wood while trapping liquid CA under the surface.
