Bob or Jerry Question: (or anyone else who has opened up a keel to see what is inside) What surrounds the pivot pin pathway through the keel? Put another way, if a guy wanted to drill out the hole through the keel to use a larger pivot pin, what is he drilling through? Is there any chance that by doing that, water gets a chance to enter the keel and go to work on the ballast? On Dec 8, 2010, at 6:11 AM, robbin roddewig wrote:
This is great info, you all know your chemistry and materials much better than I. Based on Howard's reply I already scrapped the idea of metal bushings. I don't know why I was going down that path in retrospect it seems so obvious that I could avoid the dis similar metals by not using metal. Duh! Thanks for your suggestion of Micarta. I have been looking at the materials offered by McMaster, they have Nylon, PTFE, Rulon, Ultra High Molecular Weight Polyethylene and others. Most seems to be a variation on PTFE (Teflon). My guess is that for this application anything would be functional as the board is not that heavy mechanically.
Thanks again Jerry and Howard!
