I need a glue which doesn't shrink! (Also, laser stuff!)

Hey,

I'm preparing to make a model (architectural) and I need a glue which won't warp plywood.

It's a contour model of a part of a city, and we're lasering out 3mm plywood, stacking it and glueing. Problem is, past experience has shown that normal wood glue tends to warp it, regardless of glueing it down on a thick MDF base or anything else solid.

Some layers could be screwed, and the glue could also be dabbed on rather than spread over a whole sheet, but would still like to find out if there's anything out there that's purposefully for laminating sheet material together without shrinkage.

Help!

p.s. I appreciate this is probably the wrong forum to ask but you never know

(Pinter75?!?!)

A few shots of the CAD file I'm preparing for anyone interested...

Section of Istanbul we're making, 2100x550mm in 3 panels. I had to trace round all the buildings

All the panels with each individual contour

Quick sketchup test showing how a portion of the model will come together

I don't know if that's really boring or not... I've been working on it for days and it's all I see...

Clampings not really feasible, there will be so many little bits. The larger areas of ply can be weighted down though and left to dry overnight, rather than glueing the whole model in one go and coming back in the morning to find it's all bent out of shape.

Will do some googling on your glue suggestion

Cool cheers guys, will do some research... Knew there would be a load of glue sniffing nuts in here

Forgot about this, so here's an update for anyone interested!

Got to this stage a couple of weeks ago. Still need to do bridge at bottom left and build up a few of the buildings further.

Pretty pleased with it. Each panel is 700x550mm, they fit together pretty well. I've used 3mm acrylic as the first layer to show the water.

Just PVA

Dabbed it on at 5cm (ish) intervals so any contractions/expansions would be localised and not across the entire layer causing it to warp. There are a few screws too.
