I have taken some courses in bronze casting at Red Deer college. I have talked them into adding a extra week focusing strictly on the wax sculpting part. Now I need to ensure that enough people sign up to be sure it proceeds.
Also followed by a 2 week course on the rest of the bronze casting process.
Wish Red Deer, AB., was a little closer. The investment casting process is very interesting, versatile and useful. It can produce parts very close to "net shape". I think turbine blades for jet engines are made that way, and an example most of us have seen close up; the pliers part of
multi-tools, like "Leatherman", are usually made this way, only in steel, not bronze. Go for a class in steel too, and your skills could be very useful.
The skills are totally transferable to steel. I know a foundry that will pour 4340 etc into a lost wax "investment"
Hello Les: When I started working in the early 60's at Union Carbide Canada in Toronto, my step-father was a foreman in the "jet-turbine blade" department,where the girls assembled wax turbine blades to form branches of a "tree", that was then coated with a liquid porcelain,-to produce the mould- that once cured, permitted the wax to be melted out, leaving a perfectly solid mould.In the vacuum induction furnaces, molten Stelite and/or Hastelloy alloys were poured into these moulds.When the metal had cooled,the porcelain covering was shattered away and about 20 beautiful turbine blades could be sawn off at their root. Another team of girls polished the blades to the high sheen of the finished product. Tolerances were always kept within a few thousandths of an inch! Obviously there is much automation involved in this process today.
The lost wax or investment casting procedure is an excellent process used in many fields- (gold and silver jewellery comes to mind).I am about to use this process to cast some "brass rear deck rack legs" for a 1904 Curved Dash Oldsmobile. Great fun indeed. WTF
F.M.C. used investment casting to produce the parts on the 100th anniversary T's such as front axles and spindles, that were formerly produced by the drop-forging process .
What does that tell you about investment casting?!?!
LOL William your signature at the end is hilarious. I know those are your initials but generally WTF is associated with "what the _uck". Whether intentional or not on your part this is still hilarious.
River firearms uses lost wax casting, read about it here.
Retired folk just have too much fun!
