Wow, Chet, did not realize  that price increase . No wonder paint prices are through roof  . I went and looked at last can i bought . It was $4.49 for 16ozes. .
  There guy at bottom Pa. Chalmer's I believe

Looks good ,Chet .  You may want to put hub back in and soak/ wipe  with RAW linseed oil to swell back .

Where they cut to match diameter of inside of brake drums . Most do not have tool to do and can be sanded  also . Arching gives more surface area contact to drums and would prevent vibration .

Goo . Did you arch them or have done with your measurement ?

Chet , hard to see from this angle . But do not notice much arch in linings edges . Where they checked and done .

Yes , how it is tighten down can twist back plate . You may be able to bend back to round shape in place . First check outer diameter for ovaling .

Do not think you can turn those drums if not cast iron . The steels flex . Can be mis- shapen by prior turning or hard braking . look into rounding with re-torquing to wood spokes more evenly .

Was there Thursday . Great weather , overcast and 70's . Lots of vendors , Smaller crowds . Meet with mopar parts dealers .  Stayed mostly green and orange . Glad I am on  diet , Ouch food price as bad as stadiums .

Who's going this year ?   Weather looks so-so . Guess I'll try Wednesday or Thursday .

Hope you got some drive time in this weekend . Did not on my end but will this week and next weekend .

He is looking for bottom /crank pulley .

Try size reduction .

Elevator bolt , Tee slot bolt or modified carriage bolt . 

Could not get at an edge of alum to mic . But ss is .030 to .034 or 21 gauge on corner of side where flat . I believe you have ss .

if you have both side by side it is easy to tell difference . The ss is thinner and harder . maybe a file to the edge . Your dark spots if alum. can be ware through of anodizing . I can mic both for you tomorrow unless you need tonight .
