Chainplate drilling

Hi Ben, T Y , for your reply as to the current price of Silicon Brnz per pound, from Atlas.

Congrats on your Cape George ownership, I always liked their boats, and hoped that they would acquire the recently available BCC and FC molds.

I will check the width of the brnz C-plates this upcoming weekend and send you the measurements,,, here on the forum.

I too used silicon bronze plate (1/4") for my boomkin and whisker stay chainplates,,, they seem to be holding up fine for the last 8 years.

I was happy to have Pete do castings for me, because he was a sailor first before being a foundry. He knows that our lives depend on his work, unlike general purpose foundrys.

In future I would have specified Aluminum-nickle bronze instead of Manganeese . I don't think Aluminum-nickle brnz comes in sheet or plate, just ingots .

Ahoy Ben, my dbl shroud chainplate is 2 3/4" wide and 24 1/2" from the bottom edge to the toggle hole at the top and then has the needed shoulder width. We used 3/8" carriage head bolts.

I did photograph it so that you could see the staggered hole pattern, but I don't know how to post it as an attachment yet ,,,,,,,,, oh , later I see we can't post attachments here, drats !

Another thing comes to mind, which I heard somewhere, and put to good use, is after form bending the brnz to fit the curve of your hull , then give the lower tip of the plate a little extra bend in, before mounting it. This is suposed to keep the chainplate tip tight against the hull during hull flex and loading.
