Trango Cinch new pin replacement

Love the Cinch for belaying. However, like all mechanical things, they wear. My friend Stan Miller, who probably uses his Cinch as much or more than anyone on this board, has shared his method of replacing the Dowel Pin that is the main wear point. Allowing the Dowel pin to get too low will allow faster wear on the body. As Stan is not just a better climber, but much smarter than me, his replacement went much better. So I'll share Stans routine on this.

 

Here's a newer one, this is the way the dowel pin is supposed to look. ie, new.

You can see that as the pin wears, the metal off to the left of the pin wears as well. Putting a new dowel pin in there reduces the wear on the surrounding base metal.

I figured I'd just grab our little press at work and use the new dowel pin to replace the old without doing anything to the existing jig. This is called laziness. My son had jigged up some PDFE for a job, which I took about 3 seconds to blow out. Dohh. Furthermore, as it wasn't straight, I actually blew a few thousands of the edge of the Cinch where the rope will be running away. You can see that error where the metal isn't flush to the pin in the last pic.

Stan had said that the pin came out with very little pressure.

Tore the jig out and hammered the wood in half with a hammer and a screwdriver, then used the PDFE to support the Cinch.

Out with the old and in with the new.

Gear notes:

 

Cheapo press.

5/16 x 3/4 Dowel pin

Wear reading glasses, not safety glasses so you can see what you are doing.

 

I have extra dowel pins if you want to try this yourself, ask me for one if you see me out and about. You can easily get a 5/16" x 3/4" long dowel pin at any hardware store as well.

Very interesting. I would have had a need to do this maybe next year sometime but my Cinch got "opportunistically repossessed" at the gym last week after I accidentally left it in a cubby overnight.

 

Oh well. Anyone want to sell a used Cinch?

The new Trango Vergo's are coming out. Guy on Mt Project called it the Cinch 2. But it looks pretty darned good on the early independent reviews. Maybe it is, but I like the way it appears to operate. Anyone want to try mine lets get out on rock, it should be here in a week. Here's the Trango vid.

Ha, I thought I was the only one who did this.

 

I used molding pins and they work great.

 

I actually confronted the Trango rep at the Rendezvous before doing this and he was like "We're always looking for harder metals blah blah" which obviously is complete bullshit because I found WAY harder metal just scrounging in my friends dilapidated metal shop.

 

As things are going, my pin will out-last the stainless on my Cinch and I'll probably press it out and put it in a new one before it even starts to wear.
