Egge Machine & Speed Shop - Since 1915

In the foreground are ingots of pure aluminum alloy that are heated until molten and then poured into a permanent mold (like the one Ernie Silvers demonstrates here) to form a raw casting.

Here's molten aluminum in a ladle with a capacity equal to that of the permanent mold it is being poured into.

After the aluminum has cooled the permanent mold is cracked open and the raw casting is removed.

This is Bob Egge next to a Sundstrand Model 8 Automatic stub lathe that his father bought in 1947.

Although the Sundstrand Model 8 is still used occasionally, this Cincinnati 500 with five-axis performs five different operations and does it with much greater precision than primitive single-operation machines.

High-performance piston designs that require reliefs (valve pockets) for the intake and exhaust valves are cut on this Lagun mill.

Here's a shot of an Egge piston being precision ground to an exacting tolerance.

This machine drills two holes at once in the ring land grooves at opposite ends.

Quality checks are performed after every operation to ensure perfection. Pistons that fail inspection are melted down (recycled) and have to start all over.
