Ah yea I remember back in the day when Steve King built the first loaders for himself and Craig Millet.
They were very basic, we didn't even use barrings! Bronze bushings were what we used in the first few attempts. Boy you can just imagine what happened when those let go! Clearances where not even thought to be important, boy were we wrong on that one too! I think it was the Firebird race in '74 when we finally figured out what we were doing wrong and finally designed a set of bearing cups to fit two double roller sets with two way seals, That setup would be envied even today. Built for stout too never had to work on them the entire racing year.
