Another idea for forward support on a spinner that I have seen in years past depending on your spinner is to place a tennis ball in the forward end of the spinner. The ball presses against the front of the prop and pushes against the spinner, this keeps the spinner centered on the ball. This idea has been used by guys who did not have a forward bulkhead. I have seen other types of balls plus other things in front of the prop putting pressure against the nose of the spinner, but I thought the tennis ball thing was pretty smart. Larry H.
Unless your spinner is one balanced piece of workmanship, you are allowing the forward part of the spinner to wobble a little with no support. Dana Overall 1999 & 2000 National KR Gathering host Richmond, KY i39
