Kenyon K-1374 Hinged Mastplate Assembly

This is a question for Scott or anyone who has installed the hinged Kenyon mastplate on a C22. How does the new plate attach to the bottom of the mast? The RigRite site mentions two 5/16 inch bolts and special compression spacer nuts. How do those hold the plate onto the mast? Sorry to be dense!

Thanks,
Carl

I predrilled holes and used coarse threaded screws. Very carefully screwed in one turn and back 1/2 turn then in one more turn and back 1/2 turn until the screws were all the way in.

For some reason I thought the old part of the mast base that is pop riveted onto the bottom of the mast had to come off first. If I understand right you leave the old part on and screw the new upper part of the masthead assembly onto it.

Thanks,

I would use four 2" x 1/4 to 3/8 SS machine screws tapped into the original base. Be sure to use something to prevent electrolysis between the dissimilar metals. I will being doing this in the near future myself when i get the time and money :)

You are correct, I do not remove the base of the mast prior to install.
All I did was to very carefully align the hinge, predrill new holes through the hinge and the base of the mast, and slowly tap the screw in. Use caution when putting the screws in. If you get over zellas and do not back the screw out regularly, you make break the screw off at the head!

Bet you can't guess how I know that! :)
