Rods "Spaceship" Scratch built Plasma Cutter build

Yes, the photo may have been confusing on first glance. There are a lot of wires but not that many to the Hypersensing/Ohmic circuit. Most of them go to hardware on the rail above.



I still need to tidy it all up again now all of the ohmic sensing experiments are completed. My original cutter did not have the feature so there has been a fair bit of hacking done to get the circuitry there,

Leon, I do have a THCAD board mounted right beside the Mesa 7i76e which might confuse you (There is another THCAD on the door as well for a size reference).

But yes, the 7i76e reeks of being a quality industrial board and it does have a bit of size to it.

The 7i76E is the orange terminal block + the two other rows of terminals each side (5 rows in total).
There are other boards on the same rail, I think.

Yes, there is really only the THCAD mounted at the left hand end.

I did not know what I Was doing back then so I did not use a rail but instead folded up a mount that accepts the 7i76e and the THCAD that is held on by just 2 bolts in keyholes so it was easy to remove the boards. eg. Just loosen the bolts and slide the mount out boards and all. I'll have to take a closeup for Leon.

I changed my mind. I should have done this ages ago.




Once the slats go back in they will be about 85mm above the bottom and the pan might be 3-5mm higher.


The largest sheet we get here is 1500mm x 3000mm and the flat pattern was exactly 1500mm wide. I got my sheetmetal worker who folds parts for me on his press brake to make this out of 0.9mm stainless steel. It was an awful job peeling off the plastic laser film.

Now I just have to get some sikaflex and seal around the drain plug. But my arms are not long enough so I need to recruit a helper.The plug itself is 50mm (2") and the ball valve is reduced down to 32mm (1 1/4").

I grabbed a 4 litre bottle of additive from from Hare and Forbes but I think I need to grab another one. They say to add 5-10% and I think it will hold about 130 litres so 2 bottles will be about 6%.

I thought I might need to support the base but Paul thought it would be alright with an even load and I think it will be fine, now I put some water in it.
