i have quite a bit of experience at fabricating in metal, but not wax
question for anyone, making a round wax bezel for 4mm stone.
-
how much larger must bezel be to compensate for shrinkage
-
what wax do you use and how do you get the outside
properly, evenly round
thanks in advance bill g.
Hi Bill - I’ve created a hand held mini lathe that works great for
small bezels. Shrinkage is about 3% for metal as my experience goes,
unless it’s platinum, then allow for more shrinkage. If you want to
see pics of my tool that I created let me know.

You put a wax rod (I use hard green wax for everything) in a lathe &
carve it down to the desired width- both inside & out. If You don’t
have a wax rod then file down a piece of wax until You have a rod
shape and then mount it in the lathe…or… You can make Your own rods
by pouring melted wax into lubricated copper tubing and copper pipes
I never buy premade wax shapes of anything I always make my own. Its
much less expensive and I am not limited to what the manufacturers
offer. If You don’t have a lathe then mount Your flexi shaft in a
vise and use that as a mini lathe.
