Uher 4000 repair - Start key - UK Vintage Radio Repair and Restoration Discussion Forum

Has anyone had experience repairing a loose key on a Uher 4000-series recorder? It is the Start key, which means considerable leverage is exerted between the plastic key and the metal piece to which it originally was glued.

I tried a " steel epoxy " adhesive and it was fine for a short while. But after the epoxy set, it did not adhere to the metal. I am considering drilling through the two pieces and attaching them with two small machine screws.

Thanks in advance for any advice you can offer.

Follow-up to my own question:

Needing to get the unit in service, I drilled two holes in the plastic part of the Start key and through the metal tab. I tapped the metal for #6 machine screws and then added a nut under the back screw to make sure it holds.

Hello,

I noticed you have a few UHER machines as you have three separate posts on this site. The noisy one would possibly be as easy as a dry joint, it wouldn't hurt to go over the first main circuit board with a soldering iron however it should be the DC-DC circuit. The normal component failed would be a capacitor gone either open or short circuit, if you could give me some more information I can help further. I do have many UHER machines if your looking for one to dismantle for bits.
