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,


Thank you for the explanation. I always learn something from your posts.

The 4943 should be better than the 4043, so I will give it a try. Looks like I will need to add on to my...

Alum rod

I bought it to try on a trailer fender crack. I heard someone say they donít use 4043 anymore because this is better. The workability issue was the main reason I posted here. Wonder if anyone has...

stiple

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.


I buy...

perserverance

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...

I have used the tablets and sheets. Both worked well.

make it right

I recall a quote from the owner of a 53 Nash Healey when we made a hotrod out of it for him. " If you have the last example on the planet of a given car, you should think twice before cutting it...

MIg tacks

I don't do much MIG welding on sheet. But at times it is easy to use one hand to hold the part in place and tack. I will grind the tack down before I TIG. When I TIg the seam, I hammer the sheet...

urethane bushings

Another option is using urethane die springs. Lots of durometer options and made to be pounded on relentlessly. Since if have a lathe, I just make the mating parts to fit the urethane. However,...

Lead

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...

Mandrel bending

When I have done this, I use 1/4"x12ga steel tube cut into spacers, maybe 1/4 long. I make my insert plates only .01" undersize. I use 1/8" steel cable. With a helper I use the same type bending...

430

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...

I humbly submit some advise to the Master. In past projects with similar, tube/rod edges, I minimized the distortion with a heat dam. A secondary gas purge (top and bottom) can also minimize the...
