Materials: 5/16” 4130 plate, 1/4” template plywood
Tools: bandsaw, 4.5 grinder, 1” drum sander, drill press, tig welder, large tap wrench, 3/4-16 tap
Tig welding for 3 hours in a tanktop: check
UV burns on my chest and arms: check
Should I fucking know better? Yes
Temperature in my uninsulated shop: 96F
Beers? Oh hell yes.
Finished the upper arms. When I pounded those ears down to wrap onto the tubes they both cracked at the bend. Fuckin’ weird—especially because it was obviously really hot from welding. I have no idea what material it was—it was a random piece of 3/4x1/8” bar that was sitting around. It welded fine though...
Full closeout above the spindle uniball and below what will be bump strike area. Having a c-section there worries me.
Filled the voids where the hex bungs fit into the square tube. I don’t totally hate it.
Front wrap on the other arm:
You can see where I ground out and welded the cracks in the front wrap:
Only had to run a 3/4-16 tap through one of the bungs:
Speedway Engineering makes some pretty badass rotor hats. They can be flipped front to back and the rotors can be mounted on either side and flipped over resulting in a grand total of 8 different offsets from the hub face. Here are three combos:
Settled on an offset that cleared the inside of the rim, the brake line fitting and the lower control arm at full steer.
Made a lil template out of wood:
Copied that little gem onto 5/16” chromo plate:
Tig tacked them together, drilled 25/64” through and tried to rigid tap on my drill press. It doesn’t get very far in there...
Used a countersink to add a nice chamfer to the holes:
I feel like everybody goes full lobster at least once when learning to weld. After that, it's deciding between cancer and comfort. At least for my dumb ass, comfort wins that argument more often than it should.
