I am going to build the backgauge next once I get my ball screws from A4L.

Nice job you have going there !! What are you going to use for ram leveling ?

What do you mean by ram leveling?

left side vs right side during the stroke

Look closer at the pics. There are 35mm Hiwin linear rails guiding the ram so it will always stay parallel.

ok sorry i missed that thank-you

Today I got the backgage started. I machined up the ball screws and made the end supports. I also started machining up the frame for the backgauge.

Want to follow this, make sure I don't miss anything!

Today I got the manifold all done and also the Y block.

[Bigtoy302]

I made some spacers to hold the beams parallel. Then started to tack the cross braces into place. I also cut out all the parts for the hydraulic tank on the plas, then welded the tank all up.

looking good nice job

[Bigtoy302]

Today I mounted the tank, made the motor and pump mount and also mounted the manifold.

All I can say is wow!! Keep posting, the work is outstanding and it's fun to see something of this scale come together! What is the max thickness you'll be able to bend?

I am impressed. I've been following since you started this thread.
Some of us (including me) wish we had your talent.

48" of 3/16" mild steel or about 40" of 1/4" mild steel. 3/16" is about 12 tons per foot of bend with a 1.5" lower die and 1/4" is 15 tons per foot with a 2" wide lower die.

Yesterday I got the tank all pressure tested and finished, the backgauge all done and finished all the plumbing. I still need to finish making some support brackets for the hard lines.

[Bigtoy302]

Today I got the electronics started. I mounted the control box, Wired the power supplies and the motor starter. I also cut out a front plate for a small fan and a db25 connector for the MPG. I also cut out a rear plate for the motor power wires, encoders, limits/homes switches and for the valve.

your project looks awesome! ive been kicking around the idea of making something similar. one question for you. how did you make sure your linear rails are parallel? i can understand them being correct looking at the machine from the front being that all that stuff was milled. but what about looking at it from the side? maybe im missing something but didnt notice anything that would keep the sides from pivoting independent of each other in a sense making the rails not parallel.

bigtoy - what's with the shallow-depth of green liquid in the plasma table? I'm used to seeing a water trap which is quite a few feet deep; yours looks to be a few inches...
