That's something I'd like to try, but have not seen one.

Me too, it will give much more room to widen the ports. I did a comparison between the 288 piston and BB Piston, much wider skirts!

I need another BB kit to try it on though, I've already machined the base on mine, and with the 288 piston, you can't drop the jug, you'd just machine the piston for a popup.

We've got the 288 piston and yet unmodded 7900BB cylinder. Just need the bushings

Nice, bushings are easy to make. Took me a while my first time. But could do it quicker this time. Nik should be able to make a set on his coffee break!! LOL, with all that fancy CNC stuff. I've got to do it all manually, I bet I spent 3hrs doing that set.

Al is playing around with the 460BB piston in a 7900BB kit for one of my saws. Not sure how he's progressing Regardless it is exciting me somewhat as the word "weapon" comes to mind. I hope he ports it drunk for an extra 20% power...

Ya, I'm looking forward to seeing that one!

with some of the pictures posted on AS over the years... have always wondered if some folks even use their chainsaws???

or at least keep brand new bars laying round, just for pics

Yeah you can keep the saw body tidy by looking after it but you're right with the bars. I put one tank on a new bar and it looks worse than some of the 2 year old ones you see in the odd photo here

got a new MS362 just laying around... never had fuel in it... almost too pretty to use.

Nope we just take a bunch of pics when the saws are new.

Pic was taken 9/29/09

How to adapt a different piston with different pin sizes!

What a coincidence!! I was working with bushings too!


Mine were a tad bigger...



The bushing(a bearing sleeve actually), is the silver ring in the small diameter. Small is relative though. The bushing OD is 11.500", and the ID is 10.621" Nailed the ID size at .0005" over the minimum.. Didn't want to kill it as there was better than 10 hours worth of work in it before I finish bored it. Monster 16oz. added for scale.

The bushing is on the input side of a gearcase used to drive a longwall conveyor. A 700HP electric motor plugs into this end. The project also involved truing all the critical surfaces on the input side. Cast Iron.

As you can see, the case isn't small. The setup is tough as all four bore centerlines must be lined up to within .002". Just another day of running a Horizontal Boring Mill...

A short clip of a longwall shear in operation. The coal it is cutting is falling onto the conveyor.

Couple Maple pics from today. Light was low and I'm not pleased with the new Fuji beater cam.

Base I drug home for a future GTG. Think the trailer was at its limit.

Here is a picture of a large yellow birch that I am about to cut for firewood.

My Jonsered 2171 sitting on the stump afterwards. As you can see by the shavings, it also doubles as a log splitter.

Transportation to my wood pile, my trusty Honda 4x4 quad.

The next big yellow birch that I plan to cut next week.

Same tree.

My two saws, a 021 Stilh and a Jonsered 2171 sporting a brand new 22" bar and chain.

I dont have many good shots of saws at work, but here's a couple.

My buddy runnin his 290

The Ryobi after a little noodling

Here is the 660 on a white oak stump.

Same saw, same oak.
