No Kidding!
   You mean I don't have to put up with stiff legs?

  As I remember, Gray said something like, "If you use alcohol, your legs will get all rubbery."  Or maybe he was talking about the epoxy.  Hmmmm.  Something fishy here.

      Didn't the master say that is not good idea to use alcohol to thin epoxy?  I could be wrong since my memory is bad.  Anyone remember?

        Well folks,

        Here is a preliminary finding...Considering the fact that I probably skewed the results by stirring the mixture to keep it incorporated, and the 5 minute epoxy mixture I used has only been curing for about 60 minutes, I found no detectable loss of weight on a Pelouze PS20DL digital postal scale.  I will try to attach a pic of the weight of the cup, stir stick and mixture.  
        The cup and stick weigh .5 oz, with the remainder being the mixture.  One thing you will see is that stirring the mixture makes a gelatinous mess...

          OK,  I'll take a stab.  After the alcohol evaporates you would have the same mass or weight of epoxy that you started with.  AND to reiterate what I learned from the Master Fowler, thinning epoxy, if I remember right, changes the molecular structure weakening the mixture.  It will also cause the epoxy to shrink over time. BTDT.

            Breaking news.  Here's something from Mike Harrison that will be of interest to the list.

            Ok, think about this, take 1 oz epoxy and thin with 1 oz alcohol (91%).?  After curing how much do you think it weighs and tell me why.

            Mike
