Not trying to be a dick, but your seam welds look like they didn't penetrate the metal.



I wasn't going to say it in the hopes of maintaining an ego, but you're totally right; about 60% of them didn't penetrate. I knew lap welds to be one of my weaknesses, which is why I tried to design my pieces around plug welds...

Edit: I'm thinking I need more heat, nerves, better gun angle, and some real technique.

We're finally working back at my place. Super In Law finished repairing the suspension section itself. So on to creating the patterns.

Still plan on making 4-5 sets when we get there. One for Mark. Send one to Pete at RD to set on his desk as a reminder. LOL.
Doing it by hand we will have a seam weld down the backbone.

Very cool, Cary. I'll buy a set or pattern from you or whoever on this thread is able to provide or share. Good idea on sending to RD - I don't know if I can wait that long though!

The heavier the gauge the larger the hole needs to be for the rosette weld, otherwise what little penetration was had will rip right out.

On too small of a hole on heavy gauge metal, the MIG wire will often start on the edge of the hole and barely touch the base metal.

Getting back to work. Super In Law is back to work on the ties. He just finished up the longer piece.

Patterns become 12 gauge steel pieces.

Fitted and seam welded.

Best we can tell we'll be able flip the patterns over and use them on the other side.
We'll probably have to create these in two steps. Have the steel cut out on a CNC. Then have Super In Law fit, shape and weld them. Until RD makes them for use.
