Just started too I haven't run them yet. Just got it a couple days ago . It does nice work I can tell you that. You cant get crazy with it though. It does a nice cross hatch if you use it right. I can tell you more after I run and compression test a few. 240 or 320 grit I think the cyl should be done with 280 but this is as close as I can get.

The ball hones I have I bought about 8 years ago. My favorite is the 320 grit. It will leave a nice smooth surface on the nikasil and on chrome cylinders and is not aggressive at all.
I have used them on a lot of different saws over that time and have never had any issues with plating flaking off or going through the plating. Slow and easy and do not over do it. I do a forward and reverse with the drill motor also. I want both sides of the ports to have the same smoothness. I also use regular ole 30w motor oil on the hone when I do the cylinders and then ultrasonic them when done with everything.

Let me know what you think when you get a chance to use them.

I use a soft 3m ball on a drill,makes a pretty hatch. I like to ruff the cylinder up some for new rings.

Lots of people don't but I always have,I get a quick and total ring seal.

 

[jmssaws]

This saw has had countless gallons through it,240lb compression. Rings are sealed

The oil on the skirt is beautiful, what I like to see.

what oil, Klotz?

 

[jmssaws]

what oil, Klotz?

Yes at 50:1

 

[Chris Zautner]

Yes at 50:1

That's a lot of oil for 50:1 and that's why I will be going over to Klotz

 

[Mag Craft]

Yep that does look like plenty of oil on there. I too am surprised at 50 to 1. Nice.

OK Jason, I need to know, what saw is that piston from??? Looks just like my 10 mm 044 piston, with the little wings on it. I bought a new piston for it, but the skirts were a touch shorter, and it did not have the wings, and the orig piston looked good (and was a B size), so I left it be.

What function do those wings serve??? I got other questions, but I'll wait!!! I've heard rumor they may move air around in a beneficial manner. Appreciate any comments you have.

Why don't the replacement pistons have them?

Why don't the replacement pistons have them?

Easier to make is my guess.

 

[jmssaws]

That is a oem ks 660 piston that's turned around backwards.

A mahle 066 piston doesn't have them and isn't as wide or long.

You put the drill on low speed?

 

[Mag Craft]

Yes I have it on low speed. When you put a hone in a cylinder at high speed that is when you run the risk of chipping the nikasil around the ports.
