[TheForge] Air Hammer Cylinder and valve combination

[Howell Steve]

It seems most air cylinders have too small ports for the amount of air we
would like to move through them. One garage-tech thing I did on a 2 1/2" x
14" cylinder was to take the 3/8" ports and drill them out to 1/2". No
Lathe, no scientific alignment, just the right size drill and a 1/2" npt
tap. If you have a tie-rod cylinder, disassemble it and take a close look at
the amount of material in the cylinder cap(s) and chances are you can open
things up a little.  It makes a HUGE difference. 
As far as brand names of equipment I used: SMC 5 way valve #4244, clippard
air pilot roller switch, Mead air cylinder.
I actually sold my kinyon awhile back but I miss greatly the 14" stroke that
I had built into the thing (with the bottom die out). It's the red 'hammer'
next to John Newman's in the power hammer page on photoaccess.

>>>>>The ports on my valve are only 5/16 inch in diameter by the
time the hose barbs are screwed into the valve body.  Although the hammer
went up and down, it could not strike a very hard blow.
