Home made 15 x 10 with 5 on 4 1/2 b.c. and dog dish hubcaps.
Decided i wanted to find a 10 inch wide rim and use the dog dish hubcaps.
So i found a 15 inch hoop from speedway motors.
I found and drilled out the spot welds out of the factory rim so i could weld the center into the 15 inch hoop.
The one rim had the welds on the backside so i simply turned out the welds and knocked the center out.
the speedway rim had an inner diameter of 12.625 and the factory rims center was 13.25. So i spun the diameter to the smaller size and placed it into the new hoop.
I built a jig so i could check the run out I used a spindle from a volare and the big bolt pattern rotor. I did not take a picture of the rim on the jig, but the dial indicator was placed to read the runout.
After i tacked the center into the hoop. I went and welded the rim together alternating sides so it would not pull too much.
I found after welding i was out .030 inch. Factory tolerances is 0 - .040 inch. So i was within spec. The hoop had .030 inch runout.
After i took the rim to the wheel balancer to check to see if i welded equally. One rim i needed to add .25 and the second rim i was dead nuts even. I chalk that up to my awesome-ness :roll:
I still had to drill out a valve stem hole. I mounted the rim on the bridgeport table and drilled a 29/64 hole on the 42 degree angle on the hoop.
Mock up on the wheel tub
Now just to weld it all up and then i have a 15 inch rim and 10 inches wide so i can cram some 295/50/15 tires into the new mini tub.
I finally found some tires, but now i will have to wait till i have the rear axle placed back into the car during next mock up.
