Pls recommend glue for phenolic resin plywood

[cdwitmer]

I recently found a source of excellent wood for building speaker cabinets, shelves, etc., but I'm wondering what type of glue would be best to use in joining pieces.

The wood is 15-ply mahogany plywood that has been impregnated with phenolic resin. This particular wood is surplus from the manufacturing of school desks. It is extremely dense and stiff.

I know I could use epoxy, but I'm wondering if there isn't another type of glue that is cheaper, easier to work with, and able to give equally satisfactory results.

I not only need to make right-angle abutments, but I also want to join some boards face-to-face, to double and triple their thickness.

Any suggestions on adhesives worth considering would be greatly appreciated!

Thanks

Probably the most common glue used in hobby woodworking is "yellow carpenter's glue". It is relatively inexpensive, easy to clean up (water soluble before drying), and if worked correctly strength is excellent on wood/wood joints. It sounds exactly like what you are looking for. It is essentially white glue with a crosslinking agent.

I'm also a big fan of polyurethane adhesives, but their use is more controversial among speaker builders.

Thanks, leadbelly. You mean something like Titebond II should work just fine?

I have no problems with poly glues, you just need to work fast, because the open time is limited, and make sure every thing is tightly clamped/screwed, as the glue foams when setting and can push the work apart.

However they do tend to be used for the wrong reasons, i.e. because they are gap filling, they are often used to join parts that don't quite fit...😉

Yup, or even just regular Titebond.

I made a sub using poly glue, am now making a TQWT using yellow glue, and next time, I would really like to find something with even MORE sandability than either of those. It would make finishing the MDF so much easier!

With yellow glue, wipe off the excess with a damp rag before it dries, or with both glues, use a cabinetry scraper, (about £5 here, so probably the same in $!🙂) when they are dry.

I use the discarded glass from electric welding shields as a cabinet scraper. WHERE LEATHER GLOVES THOUGH & SAFETY GLASSES they will break if you apply to much pressure but make excellent cheap scrapers for flat & convex shapes & last well too.

Off Topic, I know....

but shouldn't it be : WEAR leather gloves though & wear safety glasses ?

Seems to be mixed up a lot by native english speakers !?!? Same with "they're" and "their".

Yes it should Jean-Paul, I guess I'll have to school wear I can get myself more lesens.

Hi Tim, the reason why I ask is that I always doubt if I learnt it correct at school when I read things like that. Call it perfectionism but I prefer to do it right when I write in a foreign language 😉

It was not meant as criticism but it wonders me that so many native english speakers write it wrong while it is very easy in fact. I learnt it so it must be easy 😀
