Vance Burns reviewed his London trip and described several historic English steam engines.

Dick Kostelnicek ran his triple expansion marine steam engine. The engine was made entirely from bar and plate stock (no castings) and should generate 5 hp. from 185 lb. of steam. Compressed air was, however, used for the demonstration.

Gary Robinson showed his repair of a lathe milling vice attachment. He replaced a large broken casting with a machined angle bracket.

Charlie Hilton showed a brass cannon he made as a teenager.

Billy Hobbs displayed a cast iron ingot that he poured from a melt in a gas fired crucible furnace. Yes, you can melt cast iron in a brass foundry.

Carbide Tooling

A presentation by Joe Williams

Joe described the manufacturing process that goes into producing sintered carbide inserts.

They are packed into molds as a powder, compressed, and finally fused by sintering at high heat. The carbide cutting chips are either mechanically held onto metal tool shanks or brazed in place with silver solder. A diamond bearing grinding wheel is best for final forming of the carbide cutting edges while green silicon carbide may be used for roughing cuts. Joe distributed some literature detailing the "feed-speed cutting windows" for various grades of carbide inserts.
