I recently acquired a beautiful Empire Troubador 398, which looks & sounds great, but at some point in its many years, someone attached a Dust-Bug device onto the turntable's cast-aluminum belt/motor cover. The base of the dust-bug apparatus may have been Krazy-Glued on there. My questions is, what method is best used to remove the dust-bug doohickey, especially in trying to avoid marring the Empire's finish?

Thanks in advance!

Try acetone.

Test it on a small inconspicuous part of the plinth surface first.

It may remove the surface color tone? :eek:
 
CA (Cyanoacrylate) - Super glue gets very brittle when cold. That plus its bonds tend to have low shear strength has helped me on a number of occasions. There are commercial debonders available and as has been said acetone is also a solvent these are some others : Nitromethane, dimethyl sulfoxide, and methylene chloride. Gamma-Butyrolactone can also be used to remove cured cyanoacrylate.
depending on how long it has been cured and sitting there commercial debonders may not work, or depending could take multiple applications which can get messy and goopy.
Personally I'd try freezing it then breaking it off with a small chisel or the like.
 
I frequent some Model building message boards ( another hobby of mine) and the fellas there are well versed in dealing with CA as they use it often. I posted your question to them along with your picture and the response has been that the acetone shouldn't harm the cast aluminum at all, but try some on an unseen location first to be certain. is the aluminum surface tinted? it looks goldish in the pic.
Once you get the thing off it looks like you will be left with a largish disc of cured CA to deal with. The turntable will probably not escape unmarked.
Once removed you can use acetone to soften the remainder of the CA, but once softened not sure how you would go about removing it without spreading it around even more.

Buy a can of compressed air if u turn it upside down it will freeze the dust bug and u should be able to pop it off there

That's how I would do it.
You'll still be left with the circle of CA on the surface though.:(
 
I appreciate all of the advice, and based upon the amount of heat/cold oriented suggestions, maybe I can finally use 'global warming' to my advantage!
But first I'm going to try to freeze it off, like the wart it is, and then go for the 'soften & scrape' technique with a low-level heat gun.
I fully expect the TT to suffer some permanent residual markings, but it will either make for a great story, or give me a reason to purchase one of them new-fangled "Dust-Bugs" to cover up the stain from the old one. ;)

Stay tuned!
 
once u have to bug off soak a paper towel in the de-bonder or acetone just test a spot first and let it sit for like a half hr come back and use a old credit card as a scraper it should come right off
 
is the motor cover aluminum? if so u can bake the whole thing in the oven at 300* for 25 mins and the glue should pop right off... i use this method ungluing RC truck tires and it works great

Was crazy glue even available then? Are you sure it is not held on with double stick tape?

It's hard to say what adhesive was used, or when it was applied. I just want it off. The first step will be taking a long, deep breath and taking action. The outcome remains to be seen!
 
After I am done it will be interesting to see what type of mark is left. if it's bad enough one of my options will be to remove the "gold" finish entirely, and just go for the natural aluminum look. After all, I rather dig silver!
