Magnetic Circle Cutter

I had an old canera tripod that I modified for a traming tool about 25 years ago. Like many people I don't throw any thing away unless it is totaly shot. So I modified the old tool for a new one. Old Junk into new junk!!

Parts list

1) Old camera trypod
2) HF Magnetic ground block 30754
3) 2" dia x 3/4 long al stock
4) 3/8 - 16 bolt 1/2 long
5) 3/8 flat washer Q 2
6) 1/4 20 x 1 bolt & lock washer
7) Nut from a 3/4" diaelectric union (Plasma torch holder)

The tool will adjust from 4 in to 127 in. Much more than I will EVER use!
The legs from the trypod screw together to get to the max length

I added the roller assembly as a after thought. When the leg(s) is extended it tends to sag. the roller maintaines the correct plasma to work distance.

The 1/4 bolt is for non magnetic material. Drill a 1/4 in hole for center

Sorry, only two welds for the entire project. Some lath work on the swing nuckle, and trypod legs.

Kieth,

Cool idea. What a great range of size possibilities! I knew there was a reason that I bought that magnet base at HF when it was on sale. A new gadget to build . . .

Thanks for sharing the idea and pictures.

What a great idea Keith. I am sure there will be many copies of this floating around now.

That's really neat!! - how do you tighten the 3/4" union nut onto the plasma torch body?

I had to remove the threads on the nut. After removing the threads the nut is like a cup. Then the union nut just fits the plasma torch. The torch will rotate 360 deg in the nut.

I wonder how long it will be before the wife notices her camera tripod missing a leg.

Cool tool, dude!

I was thinking of something like that but for straight lines. Since my first chore is cutting some 4x6 sheets of diamond plate.

Keith, great idea, will keep it in mind, I have an extra tripod my Boss was kind enough to break for me, now I have a use for it.
just have to make swapable ends so I can use on AL.
