    Did you see Don Dunbar's statement on welding sand castings - can be

difficult because of the silicone (sand) contaminating the surface.

A good heads-up IMOP.

George,

    After reading so many messages, I just gotta tell 'ya:

S-I-L-I-C-O-N-E... is used to make titties bigger.  S-I-L-I-C-O-N is the
sand you refer to, and what they make computer chips outta...

    I believe that the sand (that's used in the mold) gets into surface

of the finished piece and causes both welding and machining problems.

Gee Jack - I know the difference, a bit of a typo, what's an E or two
between friends.

 I tell you this as I'm Just likely to do it again sometime, like the advert
goes - " I don't know how I can live with myself !?'
