I really wished I'd had the money to buy and transport, and a place to install
and use this 8,000 pound iron surface plate that Gorton made and used in their
factory.

Unfortunately the guy who bought it suffered a heart attack and a shop fire not
long after. Whereabouts of the plate still unknown.

I have a surface plate but its triple the weight of this mill. 4" thick,
12" x 18" Feels like around 80 lbs to me, but I could just be getting
old. :(

I'll have to locate a granite peddler for the light weight version, and
get the 123 blocks. Good idea though. Thanks TomP.

After today, I'm not so sure he is blessing us. We'll see that happens in
the next 14 days.
