Great job Herb. I bent mine by heating to red hot in charcoal bbq fire then clamped short end to a heavy piece if steel. Thel pulled the long end to the proper angle. Heat prevents possible breakage. I really like your creativity.
External chain plates, Herb, what a wonderful idea..! My wife and I will attempt to refit a 1977 Macgregor Venture 25. Chain plates are through the deck, therefore constant rainwater drip inside. I thought of putting the chain plates on the outside but wasn't sure, and you gave us the inspiration..! Thanks a lot..!
Galvanic corrosion can be mitigated. Select stainless steel alloys with similar electrode potentials to bronze, such as 316L or 317L are less reactive. Glad you got a countersink to give your dental tools a break.
Rise over run. I used that exclusively when building my ten foot scow. All my beveled joints were calculated thst way as well as the slope of the yard.
I'm surprised you're not bedding in your chain plates with butyl tape. Really seems like the best way to do it. Give a nice chamfer with the countersink and you have a wedge of rubber sealing against water.
I was planning on it, but it would have been my first time using it and I wasn’t sure if I wanted to experiment on the chainplate bolts as opposed to going with what I know to work. So I fell back to plain polyurethane sealant.
Nice bend technique…. Curious what kinda torque those bolts need? Those cheap torque wrenches are actually pretty good. The difference in accuracy between expensive torque wrench generally negligible.
Basic problems, basic answers. I have a friend who made his out of Titanium. When he got to Tonga (he was visiting San Diego and had them made m, wouldn't you know the angles of the holes (something like that ) were a little off and he could not find anyone who could drill or work with Titanium, Bronze should be easier to work with than stainless and definitely easier than Titanium . Some of the guys used amazing riggers and owners of the largest rigging companies in the world, and they made so awesome videos. They are all in my sailing rigging ect playlist and this one will be in there also. That said, the stainless bolts will corrode or fail inside where you can't see the problem. It takes quite a while but I think replacement of the bolts should be a , say, 5 year event ? What do you think ?
Looks great and fantastic job , but painting the deck every years doesn’t that cause a real build up and a problem for cracks, chips and some disbanding of the paint ??
Let me get this straight, you went to bronze to avoid corrosion in stainless but then used stainless bolts that may suffer crevice and electrolytic corrosion? Why not silicon bronze bolts?
Stainless steel bolts cost $120 but the bronze bolts would have cost $1400. I will simply have to replace them periodically until I can save up and buy bronze bolts
