[TheForge] Forge Welding Chainsaw Chain

[gblacksmith]

I have gotten my best results using anhydrous borax.  My shop is right on 
the ocean and I have not noticed significant water contamination of  my 
supply of anhydrous, i.e.; no foaming at all.  Baking regular borax seems to 
be a hassle, given the availability of anhydrous.  The foaming of regular 
borax has also been a huge pain in the ass because of its unpredictability 
in adhering to my work.  Grant
