chronometers Posted June 17, 2023 Share Posted June 17, 2023 Hi All -- I am in the process of restoring the subject speakers and one of them has some separation of the side wall and top inside corner. IA woodworking friend suggested I use long clamps to press them into place with glue. Does anyone know what type of glue would have been used during the original manufacture? 1 Quote Link to comment Share on other sites More sharing options...

Like your friends idea about the clamps. Maybe light rubber hammer treatment. Someone should be along soon about the glue they prefer. 1 Quote Link to comment Share on other sites More sharing options...

Gorilla glue is a strong glue , you must clean any residues right away , Lepage is the most commonly used wood glue / easier to remove , 1 Quote Link to comment Share on other sites More sharing options...

hanksjim1 Posted June 19, 2023 Share Posted June 19, 2023 not sure with what they used, but, I have had good luck with Titebond II...widely available just about everywhere...yes, also use the long clamps. 1 Quote Link to comment Share on other sites More sharing options...

Dave MacKay Posted June 20, 2023 Share Posted June 20, 2023 My recommendation would be to knock the panels apart, not to just re-glue and clamp. You can use a rubber hammer and a block of wood (to protect the panels) when knocking off the sides, top, and bottom. Hopefully the doghouse (the peaked element in the bass bin) is in good shape so that you won’t have to disassemble it. After you have the sides apart, scrape off as much of the existing glue as you can. New glue doesn’t adhere well to old glue; it wants to adhere to wood. Roughen the seams with 120 grit sandpaper and than apply new glue. Any good PVA glue (Titebond, Lepages, etc.) should be fine. Clamp the sides in place and use an air nailer with brads to nail them as well. The glue will do the holding; the brads provide reinforcement while the glue cures. Building a few jigs to help with alignment can only help. Good luck! 1 Quote Link to comment Share on other sites More sharing options...
