What type of glue to use

Been a while since I've been on here. Been a busy summer so far. working a lot, getting some bike riding in here and there, visiting the kids, etc., everything but making sawdust. In fact I haven't been out there since completing the dollhouse 3 months ago.

My current project is finally getting around to building a new router table. The first one I built has served me well but has sagged in the middle of the table from the weight of the router. Can't complain though as it is probably close to ten years old if not older. I don't remember exactly when I built it. Its a small, bench-top style. This one is going to be floor model I think. I doubt if it will be even close to the fancy ones I see on here but if I'm happy with it then that's all that matters, right?

ok… enough rambling… on with the question… well at least leading up to it.
My wife and I were at one of those places where you can get second hand cabinets, doors, and other construction products at a cheap price. A 3'x4' piece of double-sided laminated particle board caught my eye and they only wanted a couple bucks for it. so I bought it. I cut the one to finish size and the other one close to that with the intent of using a flush trim bit to match them up.

now… the question… yes… here at last…
what kind of adhesive can I use that will bond to laminate to glue these pieces together? I realize I will have to scuff up the laminate before applying the adhesive I just don't know the best choice.

Any ideas???

Thanx people :)

I would recommend contact cement. Epoxy would be a pain if used on a large surface area!!! AND liquid nails would be hard to get completely flat without some creative clamping!!!!

Still use sandpaper to scuff the surface first.

It sounds like you're gluing melamine. It's hard to scuff it well enough
to get most glues to stick.

I don't know how well melamine glue works for laminating, but it might
be worth getting a bottle and testing it.

I would probably do something like tilt my table saw to 45 degrees and make
real shallow scoring cuts shooting for 3/64" deep going both ways in
each piece, then scuff and glue. Since you're sandwiching two layers
for structural reasons, the cuts won't be a problem. In veneering over
melamine, you can't get away with those scoring cuts because they'll
show through the veneer.

Why use glue at all? I'm assuming this is planned as the top surface of your router table. So one side (the top) you WANT the melamine, but the underside does not matter. Right? If that's the case I might just screw the two pieces together with a few dozen well-placed screws from the bottom. Just be careful they don't come through the top! I'd probably drill small pilot holes and countersink them too. If the material is 3/4 inch, you have 1 1/2 total, so a 1 inch screw countersunk should be safe.

i think i have chosen the screw method… strategically placed that is. just have to figure out where i DON'T want screws.

thanx

put a screw at each corner, then make your top, when finished put the rest of the screws in, also in the bottom layer you could cut the hole for the router a little smaller than the top layer to provide a ledge to support the router plate, screw driven in this lip would provide leveling adjustment for the plate

sounds like a plan cutmantom. don't need to figure it out your way.

that's what i like about this place…. so many ideas, so little time! lol

thanx!
