What you have would work as is David. There's no need to clamp the torch. I incorperated a thumb screw to fix it but have never used it. Gravity is your friend. You do need to hold the cable up above the table so the cnc doesn't need to drag it. I use the overhead crane, the torch can swing in the mount as it moves around.

Thanks Greg, the torch is a snug fit in the block so I might just give it a go as-is.

Had a rethink on how to attach it to the table. Some 1X tube with openings cut for a C clamp.

Thanks very much!
It's a steep curve. Feel like I made it out of basecamp tonight.
Next I need to build an enclosure for the electronics and fab up the actual table bit.

Big progress today.
Built the removable table.
1” square receiver tubes under the table.
3/4” arms with 1” cross supports.

Made a water tray out of 22ga sheet metal and MIG welded the corners. Watertight (shocking no one more than me)

Built the electronics enclosure today.
Looked at various readymade enclosures but couldn’t find one in the size I wanted.
So I ventured into my lumber rack and got some sanded 1/2” plywood.
Had a suitably size aluminum sheet in the scrap bin to mount the various bits. Cut some nylon spacers to raise the mounting plate off the bottom.
Cut a piece of aluminum for the front to mount the aircraft connectors and the 24v power supply.
I’ll paint it black and henceforth will be known as “The Black Box” :D

I also sorted the v-wheel tensioning screw problem.
