Fantastic! I haven't assembled my press because I didnt want to spend the bucks for the jigs yet, this is a great idea. I was figuring out a way to get a chuck adapted for different diameters pins but this is so inexpensive it isn't necessary to do that.
The ram on my press is 1 inch. Checking the specs of schedule 40, 1 inch nominal has an inside diameter of 1.05 inches and should work fine if the ram specs are at 1 inch or less. I haven't un boxed it yet so I am guessing here...
1 1/4 id is 1.38" and although may be a loose fit, will work once the screw is tightened if 1" should be too tight.
I am running to Home Depot to get the piping and screws this AM! I am thinking of a way of magnetizing the endcap to hold the pin while applying pressure. Any ideas?
If I remember to take pics I 'll post.
