Model T Ford Forum: Forum 2017: Rebuilding clutch driven plate

I have a new brake drum riveted to an excellent shaft and it runs absolutely true. However, I cannot fund a used clutch driven plate anywhere near the same diameter is the brake drum. Has any one of you ever rebuilt the outside diameter with weld/something and machined it to suit a brake drum?

Allan are you sure you don't have a `15 brake drum and a 26 clutch plate?

If the register diameters are not a tight fit, you will never get the tail shaft to run true when its assembled. In cases like this, I bolt the driven plate on the brake drum using 3 bolts just snug, and with the brake drum running true in a lathe and then tap the driven plate around until it runs true. I then tighten he bolts, check it again, and then move the assembly over to the mill and then drill and ream the assembly for 3 1/16 dowel pins in the area of the spot face for the other three bolts. A bit of work, but sometimes its the only solution. I would not start welding or brazing things.

Dan, we usually set up the two components as you suggest and dial in the runout to get the best fit. Often it takes a light skim in the lathe to get the best result. The problem here is the difference in the diameter of the two, the used driven plate being worn down.

Get Dave Huson to send you a good one. I don't think they are rare in the USA.
