Replacing halyard sheaves

[rogerthebodger]

Hi Roger.
How did you keep the ball bearings in place in the Delrin /Plastic sheaves?
Locktite or some other product?

A press fit mainly but I used washers on each side of the pully to keep it in the center of the gap in the mast head filling located by the side plates that guide the halyard.

If memory serves I used 2 bearings in each sheave that in my case was the same width of the sheave.

Top pully was aliminium but the bottom was made from vesconite

I'm sure that's a good solution but I don't think I'll be able to do that with the mast up. It was hard enough try get the old sheaves out without losing them down inside the mast.

Well if yo have the existing out modification will no be an issue and you still will have to refit the new ones when done and no more work once done

Finding new sheaves is proving quite tricky, so I've ordered some brass tube and will attempt to make bushes instead. I'll look at a more long term solution when we haul out in a few months.

Hardest bit was finding a delivery address that would actually work for my $6 length of tube.
With a bit of luck these should last a few years.

Nice job - so now you’re free to do mine?
