Where do you get it ( pre war brake drums )
« on: 18 Sep 2005 at 01:47 »
I Have been playing with Douglas motorcycles for 24 years and still don't have enough brake drums to fit all my bikes I have spare wheels but no drums. Has anyone had them made or repaired them any suggestions would not go astray. Is this shortage only in Australia or world wide. Does any engineer have an opinion on how to make them Regards Daren

Daren,

I have welded new rims on the pressed steel brake drums (1925-1930ish), using the original backs.  Use 8" heavy wall tube, then turn true in a lathe after welding.  Of course to do this repair one needs a decent back/center of an original drum to start with.  One can leave the outer diameter a little larger than original to add some much needed stiffness. 

The later cast iron drums (starting in 1930 on some models till 1938) are in short supply and there is usually someone at any given time desperately seeking the same.  Eventually someone is going to have to take on the project and have them re-cast.
