Welding Tips and Tricks

Well, it took a while and a couple revisions, but I finished my circle guide for my Powermax 45. Probably more HD than needed, but I always seem to over build!



Next, is putting it to work!

It works! .... now I just need learn how to use the Hypertherm....

3/8" plate...

I need to design a guide wheel, the drag tip is not ideal for a smooth cut. The two handed approach, with one hand on the end of the rod, works okay. Cleaning the surface helps too!

Like
Overbilt,overkil, NOT

But the swing rod may be a little spindly for rest of it

Pretty slick!

The rod is 1/4" hardened steel... it is quite stiff. I cut a 13" circle and was pleased. It will probably be good to 36" or more...

That's a really nice job, I'm trying to build one with an open center with a pointer.

Very nice design, probably cheaper than buying one, them things are expensive.

Thanks,
Everything was ordered from McMaster-Carr .... probably spent $50 with a couple revisions!

Should be easy enough for the center pin, but I wanted the magnet to help keep the torch vertical that is the main reason for the needle bearing holding the torch.

I like that. I built my own tig torch holder with one of those magnets and some scrap. I literally got done doing a cut out and looked at a couple pieces and thought that would work for a tig torch holder welded them and there it is. I didn't even finish it up. It looks nasty but works great.

Pretty Impressive Glen. Really nicely made, and using the magnet for the pivot is just perfect. Great job.

Could I get a parts list?

This is basically what I got from McMaster-Carr, there is a bolt and nuts I had on hand...
