Butted tube
I have resorted to butting the tube, to prevent getting too thin or splitting. Since you have a lathe, you can make a butting tool. Basically hammering the end of the tube to make it thicker.

Tig torch length
I have 25 foot on my old transformer machine. It pretty much just sits at the bench. My portable thermal arc has 12 ft. If the machine is easy to move, 12 is best. 25 ft of cable can be a...

My torch has a 1/4" tube. Not sure the previous thread, but as I recall it was not standard. So, I cut it off and silver brazed the adaptor. If you are up for that, I can send an adapter.

bending
No reason that shape can't be formed on a press brake, with the right tooling. I suspect they lack the tooling. If you are using hardened Aluminum, spring back will have to be accounted for.

Weld table
Full disclosure, I did not drill the holes. The table is a kit of laser cut parts. The laser cut holes actually work better than drilled hole. They grab the straight shanks better.

laser filler
You can add filler with a laser. Mold repairs are frequently done with filler. But this gun thing? I have never seen one live.

hand held laser welding
Has anyone been using laser on their metalshaping? It looks like magic in the video. They are no longer priced out of reach. Similar to high end TIG.

Thanks for sharing.

drilling
Dito the lubricant. Aluminum can bond to a drill bit when it gets hot. If the flutes plug up with aluminum chips, it will not cut well.
