Replacing sheave on old Lewmar fiddle block

[LifesBetterWhenYoureBeating]

Hi there,

I have this old Lewmar fiddle block with a broken sheave and Lewmar has told me they no longer support this line. I've seen in another thread that there's a store online that makes custom sheaves but even if I was able to get one from there I couldn't figure out how I'd replace the sheave on this block. Does anybody know how?

Thanks in advance

You would have to drill those pins out and replace them with a bolt or clevis pin.

Not worth it, IMO, for prehistoric Lewmar gear. Better to invest in some current Ronstan, or hit the consignment shops for a match.

I repair old Ronstan blocks by drilling one end of the rivet out and fitting new sheaves and using bolts with the heads and nuts machined thinner. I punch the end of the bolt in three places to stop the nuts from coming off. I do it because I hate wasting a block just because a new sheave is required and I don't like the new style blocks because they have plastic cheek plates.
