Made a torch hand rest for the weld table. Started on a weld positioner kit, and figured the adjustable rest would be nice for the positioner, and using on the table in general. The positioner was meant to be driven by a drill motor, but not wild about that. So working on adapting a motor drive to it. Version one was a failure, not enough low speed torque. Searching for an alternative now.

Good info in this series Aren, thanks. I've got a Spoolmatic 30A on the way. The spool gun made the most sense for me, as I only have one MIG machine ( Millermatic 255 ) and it will allow me to leave the spool gun hooked up and independent of my steel MIG gun. I didn't want to have to dick around changing back and forth between a push pull, and the steel gun. For general repair and fab work, I think it should work great. Look forward to using it. It's coming USPS Ground Advantage, so no telling when that will be. That's life living at the end of the supply chain!

Brad Goodman Got er done. You're right, plenty stable as is, with just the weight of the 1/4". No magnets needed. Fun project that provided much needed practice, and a useful tool organizer. The stock I had was kinda scratched up and had sheared edges, so I scuffed it up with a DA sander, and put a good chamfer on the edges when prepping the parts.

Aren Jenkins Good to know, I'll have to give it a try on a bike! +1 on fitup. Even with filler, the slightest gap can cause a keyhole, and go downhill really fast.

Morning Aren. I have, and it works great and looks awesome. I'm just worried about its long term durability on stuff like a motorcycle exhaust. With the constant heat cycles, vibration, cold water hitting a screaming hot header, etc..... I just feel better having the extra reinforcement of filler material. Just started trying .040" filler, and I like the smaller beads. I need to slow down and/or use a little more heat so the beads flatten out a little more. Never liked the looks of 1/16" as the welds looked huge on thin exhaust, but that was all that's available locally. Finally ordered some .040".

Ran a practice butt joint on some 304SS exhaust tube( 2.25" OD/.065" wall ), to get in some practice time with my new HTP Invertig 251. Could be worse, but a LOT of room for improvement. Maintaining a consistent bead profile with .040" filler is a sonofabitch! Got decent melt through at 50A, but will bump it up a couple of amps next time. The 5 cfh back purge was sufficient to prevent sugaring. Used a sharp 1/16" C-K LaYZr tungsten, and Fupa 12 cup, and 35 cfh.

Nice repair, and some great tips for welding on dirty/contaminated aluminum.

Hi folks, meant to fill this out after first joining the site, but spaced it out. I've always been primarily a " I'll weld when I need to weld something" kind of guy for most of my 60 years. Started stick welding in high school and on the farm. Got into MIG and then TIG later in life. After a hitch in the USAF, I worked in telecommunications all over Alaska for 30+ years. Primarily into doing machinist work on the side, but welding a lot more after selling the mill and lathe ( preparing for our move to the "lower 48" ). With the machine work gone, welding is the new focus, and would like to up my skills. Main interest is motorcycle related welding, saving machined parts from the scrap barrel, general repair work, and just plain "making stuff". Has been a great way to spend time after retiring, and enjoying welding more and more. Also volunteer doing machine and fabrication on a steam locomotive restoration , which has been very rewarding. Sure do appreciate the knowledge shared on here. Thanks!
