Homebrew PCBs

Brad,

The Denatured Alcohol they sell in the hardware or home improvement 
stores for thinning shellac should do the job.  It is a mixture of ethyl 
and methyl alcohols, and some other stuff that makes you very sick if 
you drink it.

I had little success with the mixture of alcohol and acetone. I tried 
several ratios, with poor results.  I tried pure acetone, and got a very 
good transfer. The only problem was poor control. It was hard to tell 
when to stop the acetone soak before it toner ran all over the place. 
When I get a chance, I will try some ratios with high acetone.

Harvey
