Face/Back plate of Marshall JCM glue-down...
« on: September 26, 2011, 02:10:37 pm »
I have a Marshall JCM 2000 DSL (please...I know...) that needs to have the rearplate glued down.

What is good to use when re-tacking down faceplates/rearplates on the marshalls (and please, no suggestions to use railroad spikes!).

What I have is a part of the rearplate is comming off - I just want to use some type of cement that is typical for a faceplate that can take heat & stress.

Thanks,
-mike

I have tried all kinds of glue and have found nothing that will over time keep the rear plate in place. Heat is probably the main factor. I used tiny bronze screws on a 1974 MKII. Pictured was my glue attempt. Sat 2 days and i thought i was done with it. I had used 3M spray adhesive. There may be a glue out there some one else can say has worked for them. I may try marine 5200 on my next repair. Marine 5200 is really great stuff. It needs about 2-3 days to cure good though if you have that much time /

3M adhesive spray is useless IMHO. I've tried it for tweed and tolex and it wouldn't hold either for more than a couple of days without lifting.
 Good old contact cement,the smelly kind,works fine.Tolex is another story.

I am not much of a glue-ologist: what is the brand of contact cement to use, and is it similar to what Marshall uses?

Also: Plexi I love the high-tech use of that laptop battery for a glueing straight-edge! That will be my next problem to solve - clamping.

I thought that was an old VCR camcorder battery!    :icon_biggrin:
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Have you considered sponge adhesive tape ?

there are type with a very very thin sponge <adesivetape-sponge-adesivetape> that are very strong, also if exposed to U.V. ray

those tapes are used to attach mirrors in a quick and strong way

I tried some LePage's carpenter's glue. That didn't work, doesn't adhere to metal very well.

I use double sided sticky tape . They have all kinds, some of it is almost impossible to get apart . Most I have  found  get harder with age. I have some back plates going on 3 yrs. still stuck strong . that was with stuff made for carpets.

forget the glue.  Use a screw or screws
Guides on your quest for tone.
 Oh yeah, and I'm usually just kidding so don't take me too seriously.

This. That stuff is amazing.

Some of the most amazing music in history was made with equipment that's not as good as what you own right now.

Try a thin layer of 2-part epoxy - should work fine!

Or, Loctite AA H8610 - I use this stuff at work to glue plastic to stainless, and have used it on metal-to-metal surfaces and it's pretty much indestructible. $$ though   http://na.henkel-adhesives.com/product-search-1554.htm?nodeid=8797944414209
