Re: Hobby or Obsession?

Banning mechanical defect all engine starts. If they do not is too much air or not enough, too much gas or not enough and not enough spark.
Have been playing with model airplane engine since I was 11.

Re: Hobby or Obsession?

Up to 100 chainsaws is an hobby, beyond that is an obsession but if makes him happy is all that counts. Beside a shrink would cost more.

Unless one has uncontrollable tremor in the hands it can be done without a rest and even a if one can trust himself with a steady hand one can resort to a rest. After the main shape is obtained, removing most of the metal, putting on the...
