I had forgotten this stuff.

Where I worked before going back to school we used pieces of Phenolic about 
16" square and 1 1/2 thick for relay mounts (they were pretty good size 
relays with 500 MCM cables to each contact.<G>) They wondered why I wanted 
some of the old scrap pieces, but I could generally get a piece 2  to 4 
inches wide and sometimes full length.  It's no wonder I don't have any 
left. I went back to school in 87 so it's been 19 years.

It makes good insulators that are strong. I'm not sure arbout the fabric 
impregnated stuff and moisture.  Keep the drill speed down when makeing 
holes in it as that stuff STINKS when it gets hot. <:-))
