[TheForge] Re: shuttle - High temp glue

[Peter Fels And Phoebe Palmer]

I think the excellent refractories we make our forges 
from are a spinoff from NASA research developing 
reentry heat tolerant materials.
Bet that the economic benefits of the new refractories 
alone more than equal the cost of the space program.
I was looking for a dab of that glue today to repair 
the ceramic pilot light on the Gassaver...4th one failed.
The original version of my homemade belt grinder ( 5 
(HF) HP, 8 X 72" belt) had cobbled together rollers 
made from things like rubber boat bumpers and concrete 
pumper hose and was a perennial pain in the arse for years.
Finally broke down and had a set made at
www.mengesroller.com.
Very nice folks who produce an excellent 
product....those rollers by far and away outclass the 
rest of the machine...even after their splendor shamed 
me into getting new bearings and shafting for it.....Pete F
