I like your modification and I'm planning on doing a similar slinger using aluminum. The one question I have is why you chose to drill the oil hole to the inside of the rod journal? If you drilled the hole to the outside, its outlet would be the farthest out point of the centrifical system giving it the maximum oil pressure. Putting it to the inside might povide a sort of sump to collect any debris (limiting its movement into the bearing) but it seems that this could be done with a screen or the like. It also makes a kind of cup which will tend to hold the oil rather than sling it out. I don't know if a standard pressure engine is drilled on the inside or the out, but it seems to me that the centifical system works a bit different than a pressure system. I'm not trying to be critical, just planning out a
copy" of your engenious system
