Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Hi Gil, welcome.  I have gotten many hours so far out of my original rubber O rings on my Microcosm M90 hit and miss...wonderful unit for the money.  Sorry to hear you had a loose bearing, hopefully the threadlocker will fix that.  For what it's worth, Jin of Microcosm is also a member of this forum and many of us are awaiting a vertical engine of his creation...it should be ready to ship soon to a pre-paid 20 or so folks who ponied up $350 in advance.  After it is fully available, it will sell for more than that.  It is kind of cool having a radiator and water pump setup.

cheers and again, glad you could join us.

Roger
