Looks to be a good 'redesign' of this engine I await the first trials
Just wondering, how many ball races have you got on the main bearings, it looks like two on each side. It's often suggested that the shields on the bearings are removed, the grease washed out and replaced with a low viscosity oil, although I'll admit that I leave the bearings intact.Things look as though they are getting back together.Ian S C
A small boring bar if you have one. If not a 2 flute endmill (6 or 8mm) in a suitable holder used as a boring bar. Drills or reamers will follow the existing bore.
, but may not be as efficient as a conventional conrod and bearing, but it's good to try all types of action as it is pleasing to see the different motions of each. Ian S C
I have never really bothered much about hot air engines This well made example is wonderful I may be converted!Regards Terry
