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...

62445

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.

frame stiffness

Doing the math in my head, I'd say the stiffness would about double. Assuming solid joints. That said, I have used real stiff, fabricated wheels and they provide a constant gap between the...

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.

Rocklinizer

I used to use Rocklinizers 35 years ago. I recall paying $1500 or $2000. After I figured out what they were doing, I could make my own with a vibrating engraver and an adjustable power supply. ...

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.

My welding table has plain holes (5/8"), no threads. It is easier to keep a straight hole free from spatter than a threaded hole. There are commercial straight shank clamps available. I just...

Drilling big holes by hand

I have an old hand drill that will drill 1" holes in 1/2" steel with relative ease. Sharp bit of course. With a standard masonry carbide bit a leaf spring can be drilled. The slow speed and high...

Flame sprayed zinc

Has anyone used flame sprayed zinc for corrosion protection on steel sheet? I have a flame spray tool I use to build up warn shafts. I believe zinc powder is available.

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.

Great process, and versatile. I have made dedicated tools with broken broaches. But it was a lot of work and it only did one size.


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.
