Even good suppliers get caught out sometimes, I remember a long time ago I had to replace my rear sprocket/brake, brought from my local British bike shop who always have full Norton stock and got a new sprocket/drum but it wasn't steel but cast iron so ended up on the bike, was all good after about 10 years on the bike when it failed big time while out lucky wasn't far from home and limped home, the circlip mount where it holds the wheel bearings in the outer edge broke all the way around with only about 20mm left and everything that it held in place wasn't in place.
So ordered a new steel one from RGM but while waiting for it to come to Aus I took the old one to work put on the lathe and cut a deeper circlip groove and a 2 size bigger circlip, did the job perfect and after about 14+ years its still on the Norton and the new steel one is still sitting under the bench, took 5 mins to set up on the lathe and using an internal boring bar took two cuts and about 5 mins of work and a 2x $1 oversize circlips ( one 40mm and the other 42mm, the stock size was 38mm, ended up using the 42mm circlip).
The outer casting was very brittle where it broke, I did a thread on this when it happened with pics and how I fixed it.
