I am building the Panther Pup, a 4 cylinder 4 stroke IC Engine which was designed by the late Bill Reichart. The original engine was built in bronze and it was intended for display as opposed to the engine powering a craft. My build is based on Aluminium Castings as you can see in the attached picture .
My intent is to run this engine at exhibitions. But I am concerned that there are no provisions for crankshaft bearings in the plans. I could use R-8 ball bearings, which have an od of 1.125 and a thickness of 5/16" which maybe a little tricky to accommodate. Or I could use a much smaller bearing machined in bronze. The roller bearings can be sealed bearings where as the bronze bearings have no sealing provisions and would leak.
Do you guys and/or gals have any thoughts?
