Uher Cassette mechanism repair... - UK Vintage Radio Repair and Restoration Discussion Forum

Very straightforward to those in the know, but can turn a machine from a total loss scrapper back to normal.

I've had two Uher CG series decks with this problem, but the mechanism is exactly the same as in the CR series I have had experience with (CR 210 and CR240) so I guess it's similar to their other offerings in this format. The cassette is received by this plastic bracket, which is pushed back and past an over-centre spring to register the cassette in the machine. On ejection, the over-centre spring forces the cassette out again. It seems the plastic bracket that forms the 'stop' of the cassette is fragile enough to snap under repeated impulses.

My fix is simple, and consists of drilling three holes with a hand-held collet drill in both broken pieces; preparing three brass rods by scuffing their surface with sandpaper, then applying a reasonable amount of epoxy (Araldite in this case, in honour of my grandfather for whom it was rather a touchstone).

By the end, the part seems rather stronger than it was originally, and has so far resisted some pretty energetic tape unloads.

Assembled into the tape holder mechanism.

Simple, but effective and rather stronger than the original!

I'll have to check my CR240 and see if it needs "the treatment" !! Excellent solution.

A nice repair! I’ve used a similar technique of inserting wire support rods when repairing plastic parts. Well done!
