Alaska, if you are looking for a less expensive habit... you might want to consider crack cocaine or crystal meth. Sailing is the most expensive addiction on the planet!

You are so too late with that warning George . I think it would take an intervention at this point to get me and my wife away from sailing.

So, while picking up the grinder I show the little block with these on it to the salesperson. He had never seen such a thing and we hear a guy laughing behind us hearing us talk of drilling them out. He was a Navy machinist. He said he had ground off tons of these fittings before. They are a rivet of sorts but a custom make with a special press that puts them together. He said to grind the conclave side of the stud until the washer came off. Then tap out the head with a punch. He was right. Took about 30 seconds each.

The shafts on these are solid stainless and heavy. You would have a heck of a time drilling the "head" side of these as you will go through about a 1/4'' of material before you can do any good. The other side on the other hand is about a 16th and done.

Maybe you can drill these out, but after doing them I would recommend a grinder. These are definitely not pop rivets and are not going to drill out like one.

Now onto finding the sheaves to replace it. Thanks for all the help on this everyone.
I just got back to this....
I should have been more clear. When I wrote "drill it out" I used an oversized bit to take off the mushroomed end and then knock the pin out. Safer than a grinder for the surrounding material...sorry

That is good advice on the clevis pin...it would be a real PIA if it dropped out
