Just stepped newly painted mast with all new rigging wire and noticed to my surprise that the deck chainplates all have 5/8" holes but the rigging has all 1/2"! Do not know why I didn't notice this at disassembly. The cap schrouds at the top have 5/8 pins, the lowers are all 1/2". Good engineering would dictate a reducing bushing to accommodate the smaller pins. Anybody know what it is supposed to be? Also, how much should the support rods be tightened, mine all had a stack of lock washers above the nut, I think to take up extra space?
Thanks

Thanks for that link. My 85 only showed one place where the screw holes on top had been compromised. It has been in the water its whole life. The new design is I believe a little overkill just to stop a leak. Properly applied Butyl tape should do this and allow movement. Did find some info on Rod tightening.
Still need info on clevis sizes.

I have 1474 and they are all like that. When I re rigged boat I had a machine shop make me leaves that insert into the chain plates thus creating a tight fit. Chic
I don't claim that I am the author Tom S suggested this to me sometime ago but if you get 1/2" copper tubing the outside diameter is 5/8" it worked for me fwiw

Thanks everyone. I found some 316 SS tubing that would also work and would be more elc. compatible. Fastenal also has cast bronze bushing 1/2 x 5/8. Interesting that none of the riggers I spoke to knew about this issue.
