RE: 3 Cyl 049 radial
BMatthews,
The supercharger has sealed bearings and also has a tap to pressurise the fuel system. I am going to use a carb off of a OS 12CZR that I have for this engine. It should be large enough to supply this engine and has 2 needle valves.
I want to turn a new front and back to eliminate the chance for leakage with the 2 piece front end. There is no need to have that much material there for support. I haveot figure out a way t mount this engine. I may use standoffs that screw into the back plate to a test stand.
For the vane pump I believe you could not get by with a hack saw to cut the slits. You would need a slitting saw on a mill and a rotary table. Also what to use for the vane material? Graphite? Teflon? Sintered brass? Plus the extra weight of the pump. The supercharger looks to be built pretty light. The only weak spot I see is the belt breaking.
