DIY CS Dimple Fixture for <$150

pictures of this? i often find myself trying to get more tire clearance on already built frames and this sounds way more rad than trying to wrestle a whole frame into my bench vice

I used a couple of completely solid 3D printed pieces and one of those wood clamps to put dimples in my old SLX road frame to clear 30mm tires!

I once made this out of an old C-clamp to increase tire clearance on an already painted frame… Wrapped the chainstay in thick leather to protect the paint. It worked out quite well…

Are your initials JR? If so we met through Rollo like 20 years ago. I was active in .83 from 2007 to 2012ish, near the start but not at the start. Lots of my everyday friends came from that group!

nah, i’m terry dean! or just dean back then.
still have lots of buddies from those days too, tho we mostly just catch up online once in a while these days.

those crimps are rad, i wouldn’t have thought there’d be enough leverage with regular ol vice grips, but i guess there is!

Ah yeah, I’ve met you once or twice but it’s been a while.

No Seattle thread about Vise Grips should exist without a Val reference, so I’ll just say that I bet he would have done it this way too.

This reminds me of the little Knipex plier wrench I recently bought! That has an insane amount of leverage, I’ll try using that on the frame I’m planning to build.
It’s this tool:


Impressive leverage and you can set the width of the opening, sounds like a perfect recepy for dimpling chainstays.

Made a simpler from a tube cutter.

Needed one for a finished frame, the one for my vise wouldn’t work.

Brazed a piece of curved 22mm tubing in, where the cutting wheel was..

This is fantastic and should be posted on the Show off your shop-made/DIY Tools! thread.

I have a handful of broken pipe cutters at work and I hadn’t thought how useful that threaded mechanism could be. New weekend project coming up.

Needed one today before the frame got picked up.

Was scanning my workshop for something useful, there it was
