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

I assembled the new engines "bone stock" just so I could start planning the wood board layout, they will get tune upgrades soon.
  This morning I had a thought....what "IF" someone buys a QX-6 after reading my "flowery" thread....but has no access to a lathe or desire to tinker with the engine...So I fueled a bone stock and bone dry (no lube) engine to see what folks might experience...not real pretty!...at first the engine did not want to run and then as it warmed up it was trying a little...I just loosened one of the set screws and gave it what I would call "excessive" end play between the bearings and the engine took right off and ran "ok". It was much louder than the mod unit and the flywheel wobbles more with all the end play but it Runs.
  Hope that was full disclosure!...I am enjoying these immensely but I get a kick out of tuning them and they respond nicely to a little love. I realize most people don't have a lathe....I suppose a very thin washer special diameter washer might be the fix for a person without a lathe to prevent bearing/flywheel rub issue.
  Ok, now I have my full disclosure out of the way it's back to the engine room!
