Steve needed to decide which engine to use on his build, the 2 speed Sachs or the Villiars. We are in agreement that the looks of the Villiars is special and would fit in nicely with his tribute to the first model of Indian, the Camelback.
In the end, he too chose the Sachs. It is a much simpler installation when you consider that all he needs to make it go is a driven hub of the right size on the rear wheel... in this case he is choosing to use a MM hub adapter with a 32 tooth sprocket on a Bendix coaster brake hub. The Sachs originally used a 28 tooth sprocket, but Steve felt that he wanted lower gearing since his bike will be strictly a tri-car. Mine will be a convertible from two wheeled bike to sidecar and only occasionally (such as a fourth of July parade) be used as a tri-car. Mine will want to have faster gearing so I have gone with a 30 tooth for better top end. I should still have good start off and hill climbing power even with the sidecar. Dave, the seller of the Sachs engines said that typically the Sachs was set up to run with a top speed of 40 or thereabouts. I figure a top speed of 32 to 35 should be plenty as I will more likely be under thirty in two wheeled mode and under 25 in sidecar mode. As a tri-car I doubt I would try running it at even 20.
The Villiars will get set aside for a tricycle build Steve is planning. Had he chosen the Villiars there would have been a much different drive setup involving a belt drive, rear wheel sheave, jack shaft and automatic clutch. As a power source for the trike he will be able to place the engine in back of the seat as he sees fit and can use the kick start assembly which is not shown in the photos.
Beyond this point there will be some splitting off in threads in order to keep the focus of this one on what it is supposed to be about... an Indian tri-car. Since that his what Steve is building from the get go it makes sense for him to continue here.
My build is becoming something different that what it started out to be in large part due to the fenders and fender ornament I'll be using from a 1939 Hiawatha. So although I will refer to it as an Indian Hiawatha it will make no attempt to look like the second model Indian came out with. It will be an "Indian" never made, but will have a definite early motorcycle look. I'll start a separate thread of that name "Indian Hiawatha" soon. When my build involves the tri-car front end it will reappear in this thread.
There will also be a separate thread for Steve's sidecar frame he is making for my second sidecar made from a Grumman Canoe. Separate threads should make it easier to follow for anyone interested in making the sidecar, the frame, the first Indian tribute, etc.
