Most of the parts for this build is from Lowe's so far. Next i use 1/4" x 20 threaded rod and screw of the fender washers. I applied some JB weld to the threads first to insure the disc will not move.
Next i cut some 1/4" x 3/4" strips of aluminum to form the lower frame.
And attached to the disc.
Thats it for now since i have to build 6 more sets of disc.
