Press brake update

Tested the system without the leaky main cylinders.   Did a bit of bending with the ram on the side.



Took the cylinders to Dalhart Bearing to have the internals ordered.    Waiting on their call.   The good news is that the cast iron rings are about $18 each as are the gland seals IIRC.  Should come in under $200 if I am lucky.   Keeping my fingers crossed and hoping that it all works when I put it back together.

Learned that thickness of what one bends determines the width of the die.   This does not account for the hydraulics.

    material_thickness X 8 = die_width

The die on this machine is between 3/4 and 1" depending on how you measure it.
So it should easily handle material between 3/32" and 1/8" or 11 ga and 13 ga.  This is way more then I should need bending sheet metal.    Maybe even bend up some light frames.

The side ram has a lower die of 1 3/4"  or 7/4" which results in a material thickness of 7/32.   The 5/16" in the video was a bit of a stretch in more than one way.  Pun intended.
