Technical Been searching out info on shrinking discs

And came across some older (3+ years or so) threads, and a few folks mentioned they "made their own discs" out of 14 and 16 ga SS.

Question for those that have made their own discs, would you post a pic of them, and also the process used to make them?

I ***ume these were serrated ones?

Next question, what is used as a backing pad for them?

Thanks

 

Can you still buy them? If not I was thinking you could cut one out of diamond plate or checker plate steel?

 

10" circular saw blade. Grind off the teeth, cut notches in from the outside cir***ference with your chop saw...about 1.5" apart, and 2" deep. Works GREAT. (zero $$, pick 'em up anywhere)

 

Good info, what do you use for a backing plate/pad and what diameter should it be?

 

Good to know,thank you.
