I've just posted yet another LFMC saga at

http://www.theworkshop.ca/casting/Fo...ry5/Fndry5.htm

What I really need is some sort of industrial engineer to take me by
the hand, wipe away my tears and set me straight on the facts about
LFMC... 3 years ago when I started LF Casting it seemed too good to be
true... by my experience I think that it has been over hyped...

What metal are you casting? If it's aluminum, and if you're getting lots
of bubbles, have you tried degassing the melt? - GWE

I think his problem is bubbles under the plaster, and being too picky about
them. (

I've seen bubbles in plaster removed in a vacuum chamber (on a This Old
House episode where they do a factory tour of an investment casting
place). I've only poured one casting ever in my life, though, so I'm no
expert.
