That technology is fascinating!All that purging seems to have allowed you some room to work on out NEW skills in sheet metal and forming. Maybe a hydra-former is in your future !!
What is the capacity ?

What is the capacity ?
How wide is your press ?That technology is fascinating!
12" exactlyHow wide is your press ?
What size are the columns at the corners ?12" exactly
They are 5/8” rod.What size are the columns at the corners ?
(Those supports define a lot of the capacity of the press)
I did something similar. I imagine with much smaller holes repeated you can simulate the knurling but for all intents and purposes I found what you did more than adequate for the drawings.I have an Incra box joint jig that is missing some 1/4-20 knobs.
Drew this in Alibre but was stumped on how to draw the knurling.
The knob is 19mm across the largest diameter so I made a circular pattern of 1mm holes centered on the edge and trimmed off the excess.

The challenge is printer resolution. After I printed the first one with 1mm holes I found the 'knurl' is not aggressive enough to adequately grip.I did something similar. I imagine with much smaller holes repeated you can simulate the knurling but for all intents and purposes I found what you did more than adequate for the drawings.
Thanks Len!Looks good David !!
Did you insert a ‘threaded‘ sleeve into the printed knob ?
That's not really possible because there's no clearance above the print bed for the nut. My print nozzle runs above the bead about the thickness of a sheet of printer paper.I don’t know much about 3d printers, but couldn’t you print the knob around a rivet nut to get your 1/4-20 insert?
This is the drive assembly that has a sprocket on the RHS and couples to the lead screw on the LHS. The two sprockets will be connected with a chain and a stepper motor that drives the chain. The lead screw pulls the the other two brackets and the fence. The fence has an upper and lower part for the shear or the bender.Hard to believe these drawings for the computer controlled back fence for my 3:1 tool are dated 2007. Not yet completed because the project for the bench for the tool to sit on is incomplete. I was going to write some new software for my ELS to control the back fence position so I could jog through a series of positions. Bend. Jog to the next one. Bend. (or shear).
The bench was to hold the corner notcher, 3:1 tool and the 3 Ton press with XY positioning for CNC controlled hole punching or nibbling.

So many things to do...
..... looks to be good to half a thou of a second ... Be careful, if you tell the wife that you will be back in half a second, she's going to know that you are bs'ing....My new, precision shop clock.

Be careful David.
