when I was dropping the mast I noticed that one of the spreader mounts broke, so now i need to replace a base, or both of the spreaders and bases, I would rather not make swiss cheese out of the mast by drilling more new holes, any suggestions? I am looking ideally for a replacement base (OEM) or to have new bases made, perhaps machined out of aluminum. Does any one have bases they would like to sell? thanks
Both Capt Scott and I used a similar fix, rail support bases screwed to the mast. I then drilled a hole through the base of the spreader and fixed it in place with a screw and nut. Scott has picks on his website.
If it is cast aluminum I bet a small foundry could use the good one you have left to make you a new one. B, okay way back in the day, okay way back in the day in metal shop class we cast stuff like this, daily. We would take the original, make a mold of it in casting sand, melt the aluminum and pore it in the mold. Let it cool, knock the sand out of the frame file off any excess casting material and you were done. Could be worth a try.
Or get a bag of the casting sand. It is ultra fine grained, build a 2x4 frame, set it on a sheet of plywood, pack the frame with the sand, press the good spreader post in the sand, pull it carefully back out and you have your mold. Melt aluminum in a coffee can with a blowtorch, pore the aluminum in the mold and you have a new part.
Very do it yourself but it could work if done safely.
Cast aluminum seems like a poor choice for this application. Somebody long ago changed mine over to a more standard setup of SS brackets. My spreaders can mover forward and back and once stood up they sweep back slightly against a stop. Looks like they were rigid originally. Wonder how this effects, if at all, the sailing characteristics of the boat.
If it is aluminum, cast or not, you can grind the nub down to nothing, bore a hole the size of an aluminum replacement rod and have a shop weld it in. It will be at least as strong as the original.
When I reworked the masthead and spreader brackets on Windward, I purchased two of those. They appeared an exact match for the originals, and fit perfectly.
I used the style E base and the 2550 spreader on my C22. I could not be happier with the fit. Put the money that you would pay someone to glob some weld on there into the dwyer setup, you will not be disappointed. I used heavy stainless rivets to mount them. Just be super aware of the angles involved, try to get them straight in line with the upper shrouds.
