Jerry's Original "Howell" 2-Jet Throttle

"It is small in physical size, very adjustable and not nearly as difficult to build as it looks. The configuration and size of mounting flange (or a spigot) at the base of the unit is easily modified to suit your engine requirements. The two threaded holes at the top are for mounting an air filter (included in the plans) if desired. Otherwise, a trumpet shape velocity stack may be used instead - or your own special treatment." - Jerry Howell

Jerry's Original "Howell" Magnetic Drive Engine Water Pump

"This is the high performance water pump I designed for my 'Howell V-Four' engine. Ordinary pumps have a shaft that enters the case to drive the impeller. This requires a lubricated shaft seal to prevent leakage. In miniature sizes it can be a challenge to have a seal that prevents leaks, not create excessive friction on the shaft and be reliable over long periods of time. I designed this pump to satisfy all these requirements. There is no shaft that enters the pump case, so no seal is needed at all. It takes very little power  to turn even at high water delivery rates. The pump housing internal has an easy to produce simulated involute spiral shape with a cutwater for efficient operation and high delivery. The pump is made almost entirely of brass. I nickel plated mine for looks, but that has nothing at all to do with operation or anything else." - Jerry Howell

Jerry's Original "Vintage"

" 'Vintage' is a 90 degree engine with a horizontal displacer cylinder and a vertical power cylinder. Connecting rods for both cylinders us a single crank pin. This makes for easy construction and interesting rod motion. The engine frame (blue) is made from aluminum plate, most of the rest of the engine is machined from brass or stainless steel bar stock. Most of the brass parts were nickel plated, but that is not needed in any way - just cosmetics to suit me!

Vintage makes a perfect power source for the Miser engine. As such, it is water cooled and a belt powered water pump circulates the warm water through a ring that Miser sits on and back through the engine again. This powers the Miser while the Miser becomes the cooling 'radiator' for Vintage! Just about any other simple radiator can be used such as a 10 foot loop of vinyl aquarium air line tubing, etc!" - Jerry
