4943
I did some testing with the 4943 rod. On some 3003 ,.04"(1mm) I ran a butt weld. The 3/32" rod was pretty big for the .04" material and left a large back bead. I filed most of that away and could...

Education
Kent,

Alum rod
I bought it to try on a trailer fender crack. I heard someone say they don’t use 4043 anymore because this is better. The workability issue was the main reason I posted here. Wonder if anyone has...

I had access to a Rocklinizer for years and realized it is not magic. When that access went away, I had to improvise. I bought a cheap vibrating engraver and put a broken 1/8" carbide end mill in...

soft aluminum
I was told, by a mill in the States, that they don't ship annealed aluminum sheet because it is too fragile. It never got to it's destination without damage, so they stopped doing it.

Well done Jaro. You kept after it til you got it. Ditto on the cleaver use of the lathe. As a safety precaution, you may want to cross drill the shank for a temporary pin or bolt to keep the part...

MIg tacks

I have used both old school lead and the leadfree stuff from Eastwood. To be honest, I use plastic now. For these reasons:
The flux used with lead needs to be completely removed or you will have...

430 thermal expansion is only 60% of 304. Should have helped a lot with the weld distortion. Not that you would ever drive this through the salt of a Minnesota winter, but I had 400 series...
