    I would use CA glue gel as well.

    Later,

    Thanks for advising on CA glue. As far as SS goes, it is what it is so I have to make do.

    Any thoughts about this stuff?

    A "straight" CA glue might be too thin and grabs instantly- you won't have time to position the ring. Perhaps a gel type that is slower setting. Use sparingly.

    AFA removal of old glue, I would block the gap and try to scrape away most of it, then q-tip with acetone.

    LOL on SS's response. I can understand that a company would want to protect proprietary manufacturing techniques, but a failed joint seems to be their fault in application.

    Lol.. yeah I know. I was planning to have the shim in there, apply epoxy/whatever, press ring down, move shim clockwise while pulling it out slightly so it pulls off the excess (if any).

    That I have not and for whatever reason, overlooked this. :o

    One more thing, some construction adhesives have pretty nasty fumes. I would leave the dustcap off until the stuff has fully set. Strong fumes could cause something else to let go in the speaker.

    Any quick setting epoxy would probably work ok. I think construction adhesive is tackier and would work better.

    I'm not going to sell them - I refunded the guy and I am just going to make them into a pair of MT speakers

    JB weld work or would someone advise something different?

    I'll bite. Epoxy doesn't really stick well to metal in my experience. I would use construction adhesive that sets fairly hard. Clean the ring and pole piece carefully with alcohol or some type of degreaser. Carefully with a Q-tip. I would also scotch brite that copper ring. Use a small paint brush to apply the construction adhesive over the ring as it sits in its proper place. Use a piece of paper as Ed suggested to keep the glue off the cone assembly. Use just enough adhesive to hold the ring down to the pole piece securely.

    That's how I would do it. Be sure to let the buyer know of your repair.

    Ok so it won't be any issue. Anyone know any decent epoxy for this? CA glue maybe?
