Great! Thanks so much Bob! I will order 3/4" Silicon Bronze for the new pivot pin. Appreciate all the help from you and Jerry waving me off of the Brass! Robbin On 9/7/2010 2:16 PM, Bob From California wrote:
I wouldn't worry about an eighth of an inch on each side at all. When you were pounding out the frozen pin and elongating the hole it only makes sense to redrill a CLEAN FRESH higher diameter hole. You want something tight. A new half inch pin in an elongatated hole might move or be too loose in some areas.

Thanks Bob, did not mean to exclude you from the conversation! So there is no worries about removing too much of the existing fiberglass area that the rod is going through in each side of the keel?

Robbin.....the reason I think you should go a bit higher in diameter is to clean up the hole after you mentioned your saga removing the frozen pin. I think going to 3/4 inch would be best.

Jerry, hope you might be able to offer advice on one more point. At one point on the phone with Bob Eeg he had mentioned making the pivot pin diameter bigger. Since I am ordering new material what do you think about the benefit for something like a 3/4" rod vs. the current 1/2". I would have the enlarge the hole in the fiberglass and board but the board is trivial. Would it be worth it? Would I mess up the integrity of the section through the keel by drilling out to 3/4 diam?

Robbin- I wouldn't use brass rod in salt water because it will break down. The zinc will break down. Brass is m,ade of copper and zinc.
Bronze or monel is fine.

Sean, yes it is gratifying to walk part of the road that you paved with Dauntless. Thanks so much for the advice. I have some brass rod that I bought to replace the current "pins". Maybe that will work better. The current pins seem to be some sort of steel. I verified that during my drill the pin out phase. What does bronze look like in a pivot pin? In your photos your pins kinda look like steel. I don't think it appropriate to go into too much detail on this family oriented forum but I nearly took out my shoulder during the 'hit it harder' phase of pounding out (or more appropriately pounding on) the pivot pin. With a steel rod 'firmly' wedged into the shallow hole and my new ten pound long handled sledge I gave it a John Henry like blow that sent the steel rod ricocheting like shrapnel from a grenade. Right into my shoulder. Left a serious gouge that had it been a foot over toward my head would have been harder to laugh off! So I am very interested in avoiding steel rods shattering. Very interested. Thanks again.
