    glueing mdf rings?

    im making new speaker baffels since the last ones i made, did not allow the plastic to meet the metal b/c the mdf was too think. I tried cutting but i could not get it low enough and water has since then gotten in the mdf has absorbed it well.

    So having said this, i am now attempiting to use 1/2" (as opposed to 3/4") and then in order to get the clearance i need going to put the MDF rings on top of the speaker braket that is also made from 1/2" MDF.

    My question is How should i put togeter the 2 pieces of mdf to ensure a secure and rattle free mounting. I bought screws and elmers wood glue... is that enough, or should i use something stronger?

    Second question is, what can i put on the mdf to prevent it from absorbing moisture?

    Below is a picture of what im trying to do.

    The begining of it


    thanks in advance for the help... i will post pics... just ordered some second skin damplifier... hoping to do that as well

    I use construction adhesive. comes in a tube like caulking bonds better than glue IMHO

    as for moisture I put a layer of fiberglass resin on the MDF of my current box it seals it and doesnt let anything in.

    resin to seal would be fine, or you can go to homedepot and pick up some laminating resin. Or you can put some primer and paint over it.

    Why not just put Damplifier or Dynamat over the baffle, being careful not to shrink the size of the speaker mounting holes? No way is the mdf going to get moist that way, and you are also providing more resonance reduction.

    resin would work perfectly. and wood-glue is fine.

    sounds like a good idea to me

    Re: glueing mdf rings?

    Here are some more pics,

    The drop on the second to last pic, is Elmers wood glue.. i put a layer of it on top on the sealer to ensure that no water gets to the MDF... Apologies if it looks nasty... NOT!

    I think it looks great! 10 x better than the first attempt. Does it sound as good as it looks?
