After many years of planning to build this it is finally a reality. Just a simple steam plant with a slow turning walking beam engine, direct connected to the sidewheels. Have enjoyed many outings this past year, along the Delaware River, various Lakes on the east coast, etc. Some videos on youtube under "Sidewheel Steamboat"

You've done a fine job! Did you use the West System (Gougeon) adhesive system for the hull? If so, I hope to see you in their Epoxyworks Mag. They love intersting projects like yours. www.epoxyworks.comthumbs up

A short video of the steamer in the workshop, running with about 20 PSI steam pressure will be posted on youtube soon. Look for "Marshall-Bremme Valve Gear" . The operation of the Marshall-Bremme Valve Gear is shown, with the engine initially in short cutoff, loping along at low speed. The gear is then shifted into reverse, full gear, and the engine reverses and accelerates to a higher RPM. Then the valve gear is returned to forward running, full gear, and finally to forward running and short cutoff.

I have a computer model of this valve gear, and there are 9 "link up" notches forward, and 9 notches in reverse, giving cutoff ranging from about 15% to 85% of stroke. The cutoffs on both the head end and crank end of the cylinder are very very close for cutoffs from 30% to 85%.
