[TheForge] 15Ton Press

[Ed Fasula]

Hi Chuck,

enough advantages to my design over the cylinder on top that I

Oops.  Brain fart.  32" is the one for splitting wood.  The press cylinder 
is 6"x24"

Here is a link http://www.geocities.com/edfasula/smithing.html
to a sketch of the current thought I have for a structure.  I think I can 
keep it under 8' without too much worry.  Please criticize now, not after I 
build it!  What disadvantages do you see with the cylinder on top?  While 
you're at it, let me know if you have any input on my plan with the pilot 
valve (there also).  [Also not how I try to pass of images from my scanner 
as digital camera pictures.]

 >I'm not clear
 >on why you need to vary the motor speed in a hydraulic system.

Because I'll probably split wood with the pump (run out the forge door with 
hoses with quick connects) and I want it to go fast enough.  But I hear 
(here) that the pumps scream at 3600 rpm.  I'm not sure what speed I want 
the ram to travel at.  Some in the book went 2"/sec.  That would take 3600 
rpm with the pump I'm looking at.  So if I decided if I really wanted to 
run the press at that, I could, but sill turn it down for delicate work or 
if I was sick of the racket.

Do you know what ram speed full volume gives you?

Hope you health is coming back well for you.
