Summer of 2005 I acquired a large bucket of round to-its and finished four of Elmer Verburg's engines that appealed to me.

Because amateurs are attracted to the ease of construction of wobblers, these engines have gotten a reputation for simplicity. This design overcomes that by including such refinements as:

double acting - piston powered on both sides of stroke
reversing gear - note the small reversing lever at the top of the engine

Also included is a crosshead which significantly reduces the wear on the cylinder.

Both cylinder and standard are aluminum and I had some galling problems early on. In retrospect, the standard should have been made of steel. Nevertheless, with some moly anti-seize, the engine now runs just fine.

Marv nice work!! I took a peek at all four engine threads. I have heard of Elmers Engines but Not real familiar with them. They look like they combine the simple with inovation to make them more interesting thanks for sharing.
