Decided to make some grab handles for my welding cart (see http://weldingweb.com/vbb/showthread.php?t=38570). Didnt really need them but I wanted to try my hand at TIG on stainless.Handles: 1 304 square tubingEnd brackets: 1 x .125 304 flat barFiller: 1/16 308Electrode: 1/16 2% thoriated tapered pointMachine: Miller Dynasty 200DX @ 90 amps DCGas: 20 scfh argonPic 1: Made a fixture out of ½ angle to hold/align the pieces.Pic 2: Pieces cut and fit (less the brackets). I used a belt sander to clean up the mill marks from each piece before welding. Came out with a nice brushed finish. Experimented with 220 then 400 sandpaper followed with a buffing wheel and red rouge. Came out really mirror bright and smooth but I liked the brushed finish better.Pic 3:When practicing on some scrap stainless tubing, I noticed that the back side of the weld was all black and grainy. Sometimes the front looked just as bad. I understand (from this forum) that this is accelerated carbide precipitation and will reduce the stainless properties and strength of stainless steel. Decided to try some Solar-B flux as I heard this was as good as back purging. I tried mixing it up thin and dipping the ends of the tube. Then I wiped the flux off of the outside and the edge leaving flux on only the inside surface. Pic 4:Flux on the inside only.

Reply:Pic 5: Heres all the pieces (except the end brackets) welded up. I think the color looks nice and no black stuff. I guess the flux worked. Pic 6: Heres the finished handles. I cleaned them up with a scotchbrite wheel and used ¼-20 SST socket head cap screws, washers and nyloc nuts to attach to the cart. Got to go back to the hardware store as I only bought 4 each and I needed 8 but the handles feel really solid. Pic 7: A close-up of one of the handles.Next project
cable hangers.Thanks for looking! Attached ImagesMiller 211 w/ spool gunMiller Dynasty 200DXLongevity 60i IGBT plasmaO/A w/ crappy chinese torch/gaugesSouth Bend 10K latheGrizzly 4029 10x54 millGrizzly 7x12 hor bandsawangle grnders, bench grnder, bench belt sndr7.5 hp 80gal cmprsor
Reply:Those are SWEET! I would have just bent some rebar and welded it on, I have to start taking the time to not just "do it", but to do it really nice like you did here. I always just over build everything and forget about the "design" factor."Where's Stick man????????" - 7A749"SHHHHHH!!
