The sheave on my masthead has disintegrated. I am pretty sure that given the dimensions of the sheave and a source I could replace it OK. I do not want to go the comptip route. Anyone had experience of this or suggestions. Hobie should be able to give me the specs for the old sheave? Thanks. Rod

You just need to replace the sheave, eh? You'd probably be best off finding someone with a bent mast they're trying to get rid of. Else you might just have one fabricated? :?

It's just aluminu, I don't see why there'd be a problem with heating it.

Mast Head Sheave

The original sheave is nylon or something. Likely it is encrusted with dirt and or corrosion wedging it in there. After removing the axel / pin you should be able to pound it out with something.

We have not had this sheave for many, many years. I don't have the plans available to me to give you the original specs. You can use a CompTip mast head and CompTip Halyard.

So the CT mast head fits in the aluminum mast? That's good information; thanks, Matt! :)

With normal handskills, a router, and a pice of 1/4 delrin (or some other plastic) you probabely could fabricate one. They are pretty simple.
I could try to messure dimensions on mine. Be careful with used stuff... They all seem to be on their last leg. Patrick
