You need to get some of those red and black models and do a thread on them. They are much better looking saws.

Well now Randy........Terry has them in stock. All a feller has to do is buy one ya know. :msp_thumbup:
 
PIC's or it didn't happen.



(you tease)

I have to get these off the bench before I can get pics of the little brothers

:waaaht:

Well poke em with a stick, and put em' back together!!!
But don't get any of the red parts mixed up with the orange ones...
:msp_rolleyes:
 
I almost got them both done.........lots of pics. I'm beat though. Tomorrow I'll post more pics and stuff. :cheers:
 
A little extra potassium could go a long way. You know what you need to do next.

Is that some sort of thinly veiled primate profiling slur? :msp_sad:

I got pics uploading to Photobucket.......I might post a few. :msp_thumbup:
 


I'm not a fan of the big ass degree wheel......we have two of these made up at about 7".



Piston stop made from a decomp button for these 10mm plug saws.





If you've not seen a strato piston.....yeah, they're a little weird.

 
Smoothing out all of those casting flaws and port miss matches is where I find alot of my power. But then again I'm just a nut out in the sand with a dremel. I cant wait for more Randy, I know the owner of one of these saws.
 
Now for some machine work.......gotta bump the compression on these pretty good to really make em come alive.

This is what I mount the jug on so I can put it head first in a 4 jaw chuck. Just a 3/8" piece of aluminum plate 4" X 4" square.



Chucked up, but now it has to be dialed in.



Rob (041S) sent me this long reach indicator......I've been looking for other for quite awhile but have yet to find one I can afford.



And we are cutting......



Simple as that, .040 is gone.

 
Once the squish band is cut I check total squish clearance.



Then I know how much to cut the base......



Cutting the base.



Can't forget the cylinder extensions.....they must be cut the amount that is removed for the base, and the amount of the gasket thickness.
