KLF Posted October 10, 2018 Share Posted October 10, 2018 I'm doing the brakes on my 31 Chrysler CM6 right now and would like to find better drums. Mine have been turned quite a bit and some have heavy pitting that's too deep to get out. If I can't find better drums what are my options? Can the drums be built up and machined to size? Is anyone making repro drums?? Ken Link to comment Share on other sites More sharing options...
edinmass Posted October 10, 2018 Share Posted October 10, 2018 Use thicker friction material. You won’t find new drums. Pitts won’t affect its stopping ability. 1 Link to comment Share on other sites More sharing options...
Ivan Saxton Posted October 10, 2018 Share Posted October 10, 2018 If you look among my past posts, I have given fairly comprehensive instructions on how to do this with a Metco wire-feed thermospray coating. Metco Spraysteel LS is a machineable or grindable work-hardening coating which has similar braking characteristics to SG cast iron. You will find people in USA who use arc-spraying equipment which uses twin wire feeds. This is much quicker and more economical than the single feed oxy/acetylene equipment which I have to use. You machine on the slowest speed possible , preferably with the outside fitted with tight heavy strap of leather so you do not work- harden your job. The big old Lang Lathe which I use for this has a slowest speed in back-gear of 12 rpm. Regards, Ivan Saxton 1 Link to comment Share on other sites More sharing options...
