isn't the usual squish around .015-.017 on the 026 non pro's?just wondering. it had been a while since i measured one.i was building my buddy steves saw with a tecomec piston kit and only got .005-.007 without the gasket the other night.with the .5mm gasket i should get .025-.027.still wanted to lap the base but was running out of time before being able to flog it on some trees on the job before he gets back.he's been down and out lately since his 028 aveq and ms270 was stolen a while back.it should still be a pretty good runner.this will be the test mule with a single ring and muffler mod.

It's around .017 in an MS260 gasket delete. 026's are tighter, like .007-.008 from what I've seen myself.

Oh I'll check. But I'll use 0.010 brass shim stock and measure after that LOL

Is thin brass shim stock pretty easy to cut ? What do you guys use to cut the holes in shim stock?

Thanks drf.it may have been a ms260 i checked last.this one seemed pretty tight didn't know if it was just the aftermarket piston or not.still may tear it back down in the near future and work on the squish some more.i have sheets of .010 shim stock but haven't found an easy way to cut it yet.

If you find a right size diameter roll pin it can be used in a drill press to punch the holes. There is a tool made to make the larger hole. Find center of the larger hole. It has a sharp point to sit on the center dab. Then adjust the razor to whatever radius you want and keep spinning the tool around until it cuts through.

I'll post a picture in the next day or two

I should add it helps to sharpen the outside edge of the roll pin. This will prevent it from having a lip on the bottom edge of the shim stock

A paper hole punch can work on the thinner stuff. A razor repeatedly for the straight cuts.
I might think scissors would work to cut it out too. For the holes, I've heard one member used a spent rifle cartridge and hammer to punch holes

A lead hammer works, just taps not the swing from the heels approach. Once dented, cut it out with scissors.
