I honestly think you'll be quite disappointed with any of the cheapo ones you can buy. For the same price or even cheaper than buying your own tool, you can send it to a reputable shop and get it professionally done. The variables aer just too great with the home-job type ones. Unless of course you're wanting to just try it out on a cheap engine for kicks and giggles. Check this guy out: http://www.rayaracing.com/
 
So where do u get an expensive one, or a good one i guess u would say?I have acces to an amazing machine shop with a bunch of different style presses.

That's just a special made collar/collet what ever you want to call it. Do you have a lathe? And I bet it may have worked for a couple of tanks but I doubt it's a permanent solution. You'd also need a 3 jaw independent chuck or 4 jaw, also the chance for a screw up on that is high. I'd just send it away to get done, it seems a whole whack easier.

That's a good way to fubar an engine. I seriously doubt that he got it right in one try. There was absolutely no way to control the amount of pinch by squeezing the collar with lathe jaws and from what I saw it looked like it was way out of round when he showed the "finished" pinch. Not to mention,it looked fairly normal and still usable before he did anything to it. A worn out sleeve will usually allow the piston to come out of the top of the sleeve.

I have a good idea of how the ray-a-racing tooling is made. I have seen vague pictures of some of it and I have made similar tooling to precision re-size battery cans(missile batteries). For the price,you can't beat just sending it to them and getting it back ready to roll.

There is another home-brew method that some "say" will work but I'm not going to try it. Get a small tubing cutter(looks similar to a c-clamp). Buff the cutting wheel so it is dull and has a blunt edge. Then use it to pinch the sleeve by gently tightening it while rotating around the top of the sleeve. You're on your own here,don't complain to me if you screw up your engine.

Again though,if the engine is worth saving you should just spend the $25 or so to have it done right. If you can't afford to fix it right,how will you afford to replace it after you screw it up?
 
what not too do......

IMHO both the above videos are showing a downright hillbilly method of doing it. May as well get a channel lock and have a go yourself, it would be just about as accurate... And I get a kick out of the first vid - that thing looked like it had lots of life left in it.
 
i looked for resizing with vis-grips but that 1 was all i could find.lol/// whats $25 bucks?send it too a pro. a few weeks later like new with warrty.
