Hi all, am back in the u.k. On the wild Wirral for a few weeks and picked up my beocenter 8500 which looks and sounds amazing
the top glass panel is loose and I wondered which double sided tape available here that I might purchase to effect the necessary repair
any recommendations please, thanks for any replies
Congrats with your Beocenter 😊
When i repaired my BC 9500 And Beosystem 4500 I didn't use doublesided tape -but super glue (Loctite) for the glass panels. I guess they will never fall off Again 😉
Imo the problem with doublesided tape is that it often is too thick for the purpose. (and you never know if it will disintegrate after another 10-20 years) 😄
You can use carpet tape although I usually used a two pack epoxy personally! The two pack allows some positioning before setting.

If tape is used there is very important to get the right thickness. If too thin the rubber pegs below the glass panel will press to hard against the glass and eventually make it come loose again. If too thick you will get bad contact and bad functioning. Right thickness is 0.5mm-0.7mm. Its also important to use a very high quality tape and clean the surfaces very good. With wrong tape and/or bad cleaning it will come loos again, for the same reason as when using too thin tape.
//Bo.A long list...
As Bo mentions correct: glueing directly the frames on the panels or using thin tape, will cause to panels to loose again. It's a temporarily solution.
I've had several master/centers which had the easy "problem solved" solution, but I had to redo these. The rubber pegs presses to hard against the panels. If you're having problems with the rubber pegs touching the panels after using the right tape, then you can lift these a little. It's just a time issue that they feel like they are glued on the metal pins.
Thanks all, I will look for a good quality tape of the right dimensions. And try that, appreciate the replies

Hmm - I don't see Bo writing anything about glueing - only different thickness of tape... ;-)
I can tell you, that with the right glue the glass will never seperate from the frames again.
I have been successful re-gluing the panels on a Beomaster 9500 and 9300 using silicone glue. The 9300 was for me and the 9500 belonged to a friend. Both units are still functioning well after several months.

The silicone glue will slip after a couple of years (or 5) but will slip. 7 years ago I glued my look back mirror to the windshield of my cargo wan, with a special glue, available at car spare parts suppliers, I cleaned the to glue area with acetone before gluing. The base of the mirror is plastic, and has an area of about 2 cm2, I can pull on it, adjust it, bang it and it will not come off.

Hi Paul,
You already have some BS4500 items which were repaired with industrial superglue, how are they holding up?
Superglue has been my system of choice for many years and many BC8500/9500/9300/9000's and BS3500/4500's.
While I don't actively follow up on the sales, I have never had a complaint..........
Regards Graham
Søren Mexico:I cleaned the to glue area with acetone before gluing.
Beware with the cleaning part: the plastic frames of the BC panels will probably dissolve if you introduce them to anything like acetone.
Of course the areas to be glued need to be grease free, but start with something less dramatic, like dishwasher detergent. It actually softens the old tape & glue quite nicely, just let it soak long enough.

Hi graham, all three pieces I received from you are great with no problems, very pleased with them.
Sorry, double post
Oops

So good you just had to say so three times!!!
I would go with Graham's advice.
I think that's the right course of action, many thanks everybody
I tend more to go for the orignal way it's done.
Double sided tape with a width of approxmately 0,6mm thickness. This way the glasspanel is a bit higher located than the frame parts and the black paint on the panels isn't affected.
I've fixed three BC9500s with super glue - all done several years ago and no problems since. Great advantage is that there's no need to clean off any of the original tape from either the glass or plastic. Make sure you use super glue gel, as it is much easier to work with.
