Worked on fuel carrier arm again.
Going through my metal I didn't have long enough piece of 3x2x1/4 or 3x2x3/16 of the necessary thickness but I did find a 48" length of 3x1x3/16. In discussion my my mechanical engineer wife she suggested that doubling-up the 3x1s would be even stronger, and given the extra weight of the fuel (and it being, well, fuel) the extra strength would be a good thing.
So I decided that if I'm sistering the 3x1s, I'd weld one in to the hinge and to the first bar that sticks out rearward so that I could weld what will become the center to the ends, then sister-on the second one.
It unfortunately took a long time to clean the mill-scale off of everything before I could get to welding.
Welding the first one:
I don't have a true flat-table, but I do have a piece of a granite countertop that I've used a couple of times to get close enough.
I then ground-down the welds enough for clearance and clamped the second one in after cutting it into the right shape:
And welded everything up.
I need to grind these welds down, by the time I was done welding it was too late in the day given how hot the part was.
I'll need to weld a second span sticking out, and I'll need to add the latch-open device as well.
