I know that this is an oldish thread but it seems there is quite a bit of experience here.
Our mast has mast head
fittings for three halyards going forward. But only the center one is use for the furling
. So I want to add one halyard
on each side.
I have the exit gates, but have not yet screwed up the courage to hole the mast.
I also have two Spinlock clutches I want to install above the wInches. Now these clutches are to take 5/16" by 18 thread screws. OK, no problem. But the clutch
base is flat, not curved. The clutches are 69mm wide, a little under three inches so there is some noticeable wobble due to the curve of the mast.
My first thought was to make up a mast pad out of some (cut down) channel and flat plate bent to the shape of the mast. I will weld the cut down channel to the curved plate.
I will use Klik Rivet threaded inserts and 5/16 -18 screws to hold the base to the mast and tap the clutches to the pad (top of channel.) This will spread the load out and should make a nice installation
Am I over thinking this? Should I just screw the clutches to the mast and not worry about the curve?
Alternatively I could cut the channel down so that the center is almost touching the mast and use some longer screws to go into the mast.
I kinda think the klik rivits will be stronger than taping the mast, but they will likely not be completely in-line with the holes in the clutch
making it very difficlut to thread.
Your thoughts please.
