Welding Tips and Tricks

By all means thanks!

Start with gas. 30 cfph. I use 1/8th cerriated tungsten. I sharpen to a point then ball by switching to max cleaning (ep).
Set your ac balance to 70 percent (en).

This takes some practice.

Pick a starting point and run your heat up. I have had others watch for me and I usually go up to about 180 amps. You will see your anodizing start to break down. The arc usually favors one side. Reduce amps until you see the arc wander to the other side and break down that anodizing. I know it sounds crazy but it works. Once both sides are melting add filler and hold the heat for another second, until you see it flatten out. Reduce the heat until the puddle freezes. Not completely off like some videos show. Advance about 3/4 of the last puddle, start increasing the heat and add filler. Hold the heat and let the filler flatten out again.
Repeat this process for each step. You will use less heat as you go. Let the puddle be your indicator.

Let me know how it works for you and if you have any questions.

Here's the simple fine adjust gadget I fabricated from hardware store parts. Worked perfectly!





Fit was flat and true.

I showed my boss your notcher and he ordered one. Should be here any day.

Upgraded the Beast Tube Notcher with a steel machine stand I found on craigslist for cheap. That's a 24x30 5/8 thick ground steel fixture plate. I put my 24 inch Starrett rule across it, its still flat.

It had 50 plus years of grime, quite the chore sanding it down.



Here's the base and chip tray painted, I added some stem casters.



Drilled the 3 5/8 inch holes for the tube notcher on the new mill/drill.



Picked this up from the previous owner Friday afternoon, finished and ready for service Sunday afternoon. I'm going to let the paint bake in my hot garage for a few days.

Nice. I have a Beast as well, and yea setting the height can sometimes be a pain without an extra hand.



It is significantly dirtier now a days, since it sits outside, but I give it a good oiling every now and then when I use it.

I used mine the other day to cope some carbon fiber tubing with a diamond hole saw.

how you gonna weld up that carbon fibre tube?

TIG with carbon fiber filler rod

But seriously this Buildpro welding table and JD Squared tube notcher are coming in handy.

Nice. How much does it cost per pound?

My leg guy at one point told me the prosthetic main body was aluminum. As I found out, it is not. Not only will carbon fiber conduct amperage after a certain threshold, the resin is typically shellfish based (the ones I've used at least) and it emits a nasty puff of smoke...
