How much stroke do you need on that cylinder? I have several new Festo air cylinders in stores. May be a little larger in diameter, but looks about right on the stroke. Might be able to help you out on it.

That check valve/flow control combo.....that from Parker also? I need to repair or replace something like it on an old 9 x 12 I have.

I used the cylinder from Roy's write up. It was something like $20 from Zoro. I used an 1/8" flow contol valve I originally bought to make a clutch controller for my drag car. Think is was $9 surplus of Ebay.
 
I have had a saw like that for 20 years. I use it unmodified and love it. It works great even after having fallen off of my pickup truck.
 
Yeah, this was a great buy. Been using it almost everytime I've been in the shop. I notived there's a little slop in the main pivot but cutting not enough to make a differance in 1 3/4" steel bar. If I was cutting 3 to 4 steel it would not be 90 degree's
