Piston/Sleeve Engine Pincher

[brad55102]

Found this on ebay, has anyone used one?
Up for sale is a sleeve resizer/pincher for R/C nitro engine with step-by-step easy-to-follow instruction sheet included. You will also need a hex wrench to get started. This tool will prolong the life of the worn out P/S set that you will otherwise throw away.

I believe that's the split ring type with the allen screw to close it down. Not very accurate, but after ruining several sleeves, you could probably get a satisfactory pinch.

Is there a better kind? I am interested in this topic too.

Does anybody know if there is a way to pinch you're own sleeve? Or if there is a quality sleeve pincher available?

Olds used a good sleeve pincher. I forgot what company though. You should ask him.

Ray A Racing is the one you're thinking of. They sell the die sets to do it. Looks like great quality, but too pricey for personal use.

Rolex nailed the one being sold on ebay.

I've used the one mentioned in this thread (the ebay link). You literally have to have a delicate touch when using it. Literally just BREATHE on the wrench. It doesn't take much.

Racer 1966 is correct. A TRULY accurate one consists of 3 machined dies and a press. You're much better off letting a pro do it. It's an inexpensive and effective fix for a worn engine.

For $25, www.rayaracing.com will get it done and get it done right. I recently had him do a mild pinch on 3 sets. Did a nice job on all 3. Also polished the tops of the pistons when he was working on them.

He does sell his stuff, but as mentioned, it's a bit spendy. If you had a shop/LHS or something, you could definitely get your money back or make many nitro friends by purchasing. But beings I only spend about $50 a year getting it done (if that) for myself or my friends, having him do it works out fine for me.

I wrote up a pretty detailed thread on the before/after of my most recent sets I had done.
