HI I have a newly acquired Coronado 550 that has a nice cabinet but was stored in a damp place and is de-laminating in the past I've tried white glue and liquid hide to reconnect the panels.
I would like some feed back of how you may have done .
Thanks Rich :P

I would apply the correct white glue let dry overnight, then press down the veneer with a hot iron. Lots of expert descriptions here.
It may need to be dampened and clamped flat, let dry, before going to the glue stage.

HI John, thanks for the input, I was thinking the same thing. I glued the base up with hot hide glue but I don't think I will do that to the sides. I acquired some glue from Joe's veneer supply that is intended to be Ironed on, it looks like yellow glue. not sure how that will work I've never tried that stuff. what do you think?

Tite-Bond #1 I think is good, simple white glue, dries clear.

Correction- it is actually a yellow glue type. Have glued curved veneer with is successfully.

To me that looks beyond just squirting in glue, iron or not. Must be loads of accumulated dirt in there. You could try folded sandpaper and an air line first.

White glue on a Zenith, done like that, didn't work for me. It came back up again some moths later.

HI, I used the Heat-Lock adhesive and injected into the gaps then worked it to the center with a veneer hammer. I weighted it with a granite stone but that wasn't enough ( should have used clamps).
on the next day I tried to Iron the panel together but it didn't work very well because of the thickness of the wood so I clamped angle aluminum on it and heated with a propane torch to about 160 degrees F and let cool.
this worked extremely well.
Rich :D

HI just tested the chassis, the antenna coil and the IF transformers are all open. I guess it got struck by lighting. :cry:

Its looking good with some toner on it. But will it last in a central heated house? I was suspect on just gluing the remains of the top back down and an extra veneer layer could make it more likely to lift.

Please let us know how it is in a years time.

Merry Christmas Gary

hi Gary I now have 3 radios that have been repaired the same as my 550 that are about 3 years old and show no signs of de lamination.

Well thanks for the reply and sharing the success you have had. When I tried it about 15 years ago maybe the adhesives were not so good?

I think "fred" did one 'over the top' as well so he must be confident that it will be ok. He didn't get back to me on it !

A pretty phenomenal restoration of that cabinet. Good work!

What is this process of stripping with wood chips? I haven't heard of it. How's it done?

Yes, I'd like to know too, what is the process for stripping using wood chips? Cheers, Russie

Hi the chips are used after the stripper has softened the finish, (I Use the toxic stuff). the planer chips or hamster bedding from the pet store is needed. with chemical gloves on spread the chips on the surface and just rub until you get most of the material off your project. don't use wire brushes to remove any residue. anything that is left is taken off with a soft cloth and lacquer thinner. some times I will use a natural wisk broom to get in the crevices but most of the material is picked up by the wood chips.

Ah, now I get it. I use Zip Strip and clean it off with Lacquer Thinner soaked fine steel wool. I think using wood chips is a better idea for cleaning it off, I have lots of sawdust and planer chips. I'm going to give it a try on my next project. Cheers, Russie
