Rogers, Thor, Synchro, Buzz, and one with no name!

Anyone ever run one? They look kinda crude!

  I have had a few real odd engines pass through my hands, but never any of those. Some guys have run them though. Maybe after some rework.

Just like you wouldn't catch me dead owning a "bonnet," and the only thing that is supposed to go in a "boot" is your foot....

Even the guys in the north end of Boston are just pretending to speak the King's English nowadays.

Back to slag engines...what I've read is that they typically had a bare aluminum piston running in a bare aluminum bore. Seizure or short life is almost assured. Easy machining may have been the reason? Those guys were largely pretty young and had lots of enthusiasm but not a lot of engineering or machining education. I seem to recall reading that the Rogers was designed and made by a barber, but I certainly wouldn't swear to that as fact. A lot of early gas FF designs were structural nightmares, so that's about par.  D>K Steve

I've only recently become interested in older engines.  And after looking at those, I can safely say I've had water-cooled engines with more cooling fin area !!  "Run Hot, Run Once" should have been their sales pitch.

I have a Rogers 29 slag engine.  It looks like never ran (understandable).  Compression so poor that I never tried to run it.

Some may think that the Dennymite .56 engine was also a "slag".  Not so.

Although having a cast iron cylinder and cast iron piston, it runs very well, despite its being very heavy.

My Dennymite is near-new.  It has a few minutes run time on my test bench, but no more than that.
