I'm new to the orchid forums and i just wanted to begin by thanking
the creators and also the members for this wonderful community. I'm
a beggining jeweler and i'm just attempting to begin casting.
Right now i' just installed my casting machine on a 250 concrete
base set in wood. When put the flask into the cradle, melt the
charge and trip the spring the silver always shoots out of the
either the sides of the casting crucible or the actual flask pops up
out of place and the silver shoots through the bottom of the
First off the area the casting machine is bolted into is level and
very stable it does not move at all. Its set into a 250 pound
concrete base and with the pot its in it weighs close to 300 easily.
The casting machine is one i bought from santa fe jewelers (basic
buffalo dental casting machine).
When the actual silver does go in it forms incomplete castings.
(some of it shoots off the rest actualy goes in when i tie flask
down with binding wire).
I can't figure out what the problem is. I'm doing everything by the
book: 2.5 turns, sprues are the correct size, silver is molten to
where it begins to swirl...etc. I honestly don't have a clue why
this is happening and i'm losing a lot of silver through this
Any help would be appreciated:)
