It’s ok Chuck. Without getting into a long discussion, this is what I do for a living, for most of my working life, so I do know what I am doing.
You don’t want to heat SS to form it, or any other reason, because then it is soft and rusts. SS is generally cold formed. You can bend a piece back and forth 180 degrees several times before it will break. We do that for weld tests. Don’t worry, I am not going to put Matt in jeopardy.

Really?? Bending it back into shape? Finding replacement pins for 30 year old blocks that are twisted and falling apart? You need to consider metal fatigue and once stainless steel is bent without applying heat, it is severely compromised. I’m as cheap as the next sailor (well maybe not the Canadian ones…) but once a piece of critical hardware gives up and gets bent out of shape, it finds its way into the scrap heap and gets replaced because I don’t depend on damaged hardware to get me home safely.. Maybe because I love my children and my wife and want to see them again. Just for the record, if the snatch block lets go under load and kills someone or severely injures a crew member, I hope you have enough liability insurance because it will not be something you can pin on a company that has been out of business since 1989. If you have a single piece of electronic gadgetry or cookware on your boat that costs more than a snatch block and have limited financial resources, I suggest you sell them and buy the new hardware that you need. And yes, I am well aware that new snatch blocks are expensive..it’s for good reason!

I can probably beat it back into shape. Might cost you a beer or two, tho. I used to repair Merle’s Merrimans, and now of course I own them.

Wolford via CnC-List Sent: Tuesday, April 09, 2019 1:15 PM To: cnc-list@cnc-list.com Cc: Matthew L. Wolford Subject: Stus-List Merriman snatch block question Listers: I have an old Merriman snatch block in need of repair. It was under load last season and not properly closed, which caused it to open and bend the stainless straps (on the sides) and the pin holding it together. I believe I can bend the stainless straps back more or less into alignment. However, the pin is bent and in need of replacement. The pin used by Merriman for this block is stainless, 2 1/2 inches long (I’m guessing 5/16 diameter) with a head on one end and internal threads on the other. It is held together by a machine screw that screws into the threaded end. I suppose I could use a stainless bolt, but that would not be very elegant. Any ideas?
