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

These were never intended to run with the precision of model engines. Yes, I saw the wobble on the first run but really doesn't bother me. It's a toy that's over 125 years old after all and I won't risk doing any straightening of a very slight irregularity in the crankshaft. The longer I'm in this hobby the more I leave well enough alone, but realize not everyone approaches things the same way.
