I went into work this moring with a 50 pound packet under my arm, well it was breaking my arms actually. I left tonight with slightly under 32 pounds.
I rough machined the rotors leaving only a slight cleanup cut on them.
The back side is machined to the stock 2 inch wide braking surface, I actually left 2.1 inches to be sure.
The front side or the side the hat is bolted to is 2 1/4 stock to clear the caliper and I left an extra 12 inch for bolting but I can trim that down later.
Each rotor lost about 8.5 pounds. They started at 24.86 pounds each and came out at 15.8. This is the initial machining.
I will try this weekend to drill a pattern on the rotors. I will actually figure out tomorrow what I will weight if I drill about 240 holes at 1/4 inch each.
Anyone know what a hole 1/4 inch by .265 doesn't weight??? :lol: :lol:
Anyway in these pictures the surface facing up is the back side of the rotor, it is .1 inches wider then stock. The side down on the carpet is 1/2 inch wider then stock for bolting the hat to the disc.
I made this hat before seeing the disc and afterwards thought it looked way too small. I am scrapping it and remaking new 10 inch ones.
This hat fell right into the hole I bored in the disc
This is the stock rotor beside the new 14 inch.
This is a machined rotor beside the stock one.
This is the machined rotor with the 8 inch standard size hat sitting in the middle
The hat is way too small for this size of rotor and I will move up to 10 inch
Another closeup of the machined rotor
This is the back side, not the side that the hat bolts to
Once the hat and rotor are bolted together and I plan on 18 screws per rotor along with a slight press fit of the hat into the disc for centering I then put the two piece, hopefully now one and remachine all surfaces on the disc for finish and truing it up with the hat. I left an honest .010 for this purpose.
