Its good the wire and mylar bond instantly when the glue has dried for a while BUT!, - sounds a bit scary, - having to have it lined up so well, - What happens if you miss the grove? do you just leave it and hope it won't make any difference and move onto the next wire?!
I might use the 30 stuff as well, - will have to get more opinions first though as I've read conflicting stuff on whether its needed or not.
Cheers,
Colin

If you miss where you want it you just clean up the area again with acetone and redo it, not real hard just a pain in the Arse !

  Thanks for the tips.
  Yes of course, - just use the acetone again, - stupid me.
  As for the sock, it just seems such a pain to take the wooden sides off , - undo all the staples , remove sock, do the repair and then put the sock (or a new one if the present one is compromised) then re do the staples. I can clearly see on the rear side of my speaker under the black sock the areas that need to be addressed at the top and bottom of the speaker where the banana peel is. Can't I just get a small pair of scissors and cut a flap in the sock to access the area?. Not sure how I would put the flap back, - cou;d use some glue or perhpas even better just sow it back with some black cottom. = seems simple enough?. I know you might see something was a bit weird at the back of the speaker but you would not see anything at the front.
  
  Cheers,
  Colin

    Uh, no. You are going to have to strip her down. Otherwise you'll never be sure of what you might have missed.
    
    I'm sorry, but all this is part of the "fun" of owning vintage Maggies.
    
    Physically they are a very simple system, but even so there are nuances to the failure modes. But these are all known and for the most part easily repairable.
    
    Don't despair. as long as the Mylar isn't seriously ripped and your ribbons are good, you're not looking at major expenses. Just a certain amount of application of principles.
    
    Good luck!

      Cheers Guys,
      My issue with stripping it all down was the risk of ripping the front of the sockwhen taking th sock off. I am in the UK, - shipping from the USA for new stuff from Magnepan is not cheap and slow.
      If I managed to get the sock off and on without problems then fine, - but I might rip it!
      I am tempted to just cut out the whole of the back of the sock off so I can check everything (mylar and wires) on the back and then sow the back sock on afterwards, - then at least the front is untouched, and I won't have to undo the staples. The back might not look perfect, but it won't be seen from the front. Is this still a bad idea?!!!
      Andy your bolts look like a good idea. The glue as well, - what sort of glue did you use for that?
      Cheers,
      Colin

        Hi Colin! Two time Maggie sock remover here! Those socks are a bit tougher than you think. I hadn't planned on saving the socks on my MMG's or MG2.5's so I wasn't real gentle about removing them. Guess what? Nothing ripped. Removing those staples and socks, consider it a right of passage ;^) . It elevates you to a higher level among us here in the Asylum, LOL.
        
        If you are still finding it hard to acetone, get some fingernail polish remover. Guess what it's made of, acetone. Doesn't matter what brand, just get "fragrence-free". One or two bottles should do the trick. Less left over than a big can from the hardare store.

        Thanks again Rickey,
        Thats some comfort, - the stapes are a bit daunting though, - how many are there? like about 100?! Its good to know the socks are quite tough.
        Did you buy a stapler to staple the sock back on afterwards?
        Cheers,
        Colin

        Didn't use socks on my Quasi-Gunned MMG's, don't plan on having socks on the 2.5's when they're done. But jeeze-loueeze, I don't understand why Magnepan uses so many. The term OVERKILL comes to mind.

        You could cut the sock off of the back, but I think that it would be harder then you imagine to sew a cover over the hole. If you are going to go this route, I suggest that you apply velcro strips to the sock and the covering fabric. This will make it easier for you, and provide easy access to the panel for any future repairs. I still think that removing the sock and keeping it intact is the better option. It will keep them original, and not hurt the resale value of the speakers. I have removed the socks from dozens of maggies, and never ripped a single sock. The trick is to be patient and be sure that you have all the staples out before pulling. It may seem like a daunting task to remove the socks and make the repairs, but I assure you that it is not. But the choice is ultimately yours to make. Good luck on the repairs.
        -Greg

        Thanks Greg,
        Gonna have to have a long think. thanks for your tips on removing the sock in tact, - will bear that in mind. The thing with these speakers is that I they haven't got have the external passive crossover boxes (the shop I bought them from had lost them) so the resale possibilities are quite limited without these obviously,- I knew this when I bought the speakers, - I don't intend to sell them on - which tempts me to just cut the back and use velcro like you say (velcro is a good idea, - thanks for that, - much better idea than sewing!). This way I do avoid all the staples, taking the sock off, and its a 10 second job to get back to naked panel if I need to in the future by just taking the velcro off.
        Will have a think, - I going to email Magnepan and ask for the cost of the socks with shipping ot the UK (in case I rip the sock if I go that route) so I can weigh up which way to go.
        All the best,
        Colin

  - Colin, if it's worth doing ... it's worth doing properly - right? :-)) ... - andyr 20:27:08 08/23/10 (0)
    You don't want to have to do some more glueing down somewhere else in 6 months time, do ya! :-)) You really need to examine the whole of the mylar for green or red or corrosion spots ... or simply for any short lengths of wire that are coming unstuck.
    
    And once you get Maggie naked, you'll understand more about how she "works". :-))
    
    Anyway, here's an old pic of my naked IIIas. They weren't stock at that stage but they were in their original MDF frames - which had been stiffened by glueing aluminium U-channel along the 4 sides. All the bolt heads you can see were from the clamps I used to fix the bass/mid driver panel to the frame (replacing the crappy staples) and replace the ribbon cage screws (as they tend not to hold in MDF).
    
    And my panels were reversed when I bought them (to get the mylar at the front).
    
    Regards,
    
    Andy
