Broken Zenith 10S690 Flywheel Tuning Shaft

[vortalexfan]

Hello everyone, the other day I was trying to replace the belt on my Zenith 10S690 tuning drive mechanism and when I went to put the new belt on the knurled bakelite shaft broke off of the flywheel assembly where the belt would attach, and I tried gluing it back together but no luck.

Does anyone here have any experience with repairing this issue, or have a way to fix this?

I tried looking on everyone's favorite auction site but nothing came up.

any help with this issue would be appreciated.
