A few weeks ago there was a thread and questions on making
casting and lapidary euipment.
At that time I knew a I had abooklet on the main items - a good
HOW TO… -but could not find it.
I found it today ; it provides HOW TO and working plans to make
Vacuum Investment Mixer
Burnour Oven (600W of higher)
Pressure Casting Machine
Simple Wax extruder
Also : How to make Rubber Molds
Invest Wax Pattern
Burn Out and Cast
Rubber Molds and duplicate Patters
Rubber Molds without vulcanizing.
In all instances there are working blue-print type plans,
photographs and a sort bill of materials - For myself I built a
600W Burnout oven because the commercial ones were all 1800W+,
and as a hobbyist I never cast more than 2-3 pieces at a time.
My apologies to the bigtimers on the list - these notes are
basically for the small-time hobbyists like me.
The booklet is:
