The only one I know that makes tools right now is RAY A. aka Rayaracing. I think they are over $500.00 but not sure. You can have alot of sleeves pinched for that much. I use a totally different method but I do not sell them. I would not recommend the cheap clamps I have seen, they do not squeeze evenly and do not keep the sleeve round.

I do not reccomend doing this- I am sure you need good tools to do the job right. You will be much better sending it to Rex, he knows what he is doing and I am very happy with his service, every time I send a piston/sleeve set the engine works as new when it comes back home , ready for racing. You will get a lot more for your money than buying those clamps

This is why most drivers today have no knowledge. "Please don't do it by yourself!"

If he has engines which are ready for a trash can, who not give it a try?


For many thing I also do some investigation before I start with an own idea. I started with a machine clamp



With a small conical shaped ring I give my sleeves a pinch. With a smal scale on the nut I can go to the excac point to which I have done if it is not enough and ad a small step to it to see if it is OK.



And if needed I use a hone tool to finish the sleeve:

Ray A is the one I trust with my engines. Rex maybe good but I have not had one done by him. I would be careful who I trust with my engine.

In the early days I destroyed heaps of liners doing various things, go for it, it's fun.
I look back now and laugh, but now I am a respected engine rebuilder here in Aus.

What are you guys using/making your rings to go around sleeve? Copper aluminum pipe cutting it? Trying to see what works best.

It needs to be something hard.
Because I use an ER32 clamp with the largest size 20mm and sleeves of 15.5mm I used a piece of a metal strap band for heavy boxes. On my mill with the vice under a slight angle I could mill a taper on it and bend it arround a sleeve.

For smaller diameter sleeves I made adapters on my lathe from a bar of steel so I can do 17, 17.5, 18, 19.2 and 19.5mm sleeves.

I also found an oversize ER32 clamp of 22mm so I made a small adapter ring to fit 21 and 21.5mm sleeves from .28-.32 engines.

As a machinist I always thought a collet chuck would be they way to do this. Nice to see that’s how you are repinching sleeves Roelof
