I know its an old thread, but I am curious as to the success
rate of Vac versus Cent…
I have, and continue to try centrifugal… I believe I have tried
everything known to man and even smart apes( if they have an idea
as to how to improve my casting success.)
‘IN THE HOLE’ casting isn’t a problem !!! But sometimes I don’t
want to do but one/two etc., rings at a time… THEREFORE, I try
to do 'ON TOP . . THROUGH THE LITTLE 3/8 INCH HOLE(PLUS OR MINUS)
with a small cylinder… AND IT JUST DOESN’T WORK BUT about 50 %
of the time!!!
I pour at 900 degrees, with a vacuum, quickly, and sometimes it
just provides small or large pieces of the item . . .( Boy, have
I learned to weld!!! next note … found a good product).
So you Centrifugal out there… and other vac’er… what
percentage do u return… I have just bout had it … on to
Centrifugal??? … lost 3 or 4 nice slides which were a heck
of a lot of work!
