Webmasters note!
Paul demonstrated this engine running at the May 2006 meeting. Remember, the plans were only published in the December 2005 issue of HSM.

The Duclos Gearless Hit N' Miss

The Duclos Gearless Hit N' Miss was feature in HSM beginning in May 1993. The engine is also featured in the Village Press Publication, " Two Shop Masters- Frank McLean & Philip Duclos" . The engine bore is 3/4" and the stroke is 1 1/8". A Push Rod activates the exhaust valve with trip Indexer.

This is my first attempt at building an Internal Combustion Engine. It is also the lengthiest project that I have attempted. The plans were complete and error free. The written directions given by Mr.. Duclos were a pleasure to follow.
