Thread: Techniglue Question

epoxy ply wood! wow that's like super ply!
how thick that the veneers?
That also makes for some very expensive laminations too...

Techni glue actually needs space to be at it's strongest. So it will be very difficult to reduce the glue line.

Why not use Titebond? Do you want no flex what so ever?

Thanks for the quick reply,
Its not just normal ply, the end products are ply drum shells. I was using Titebond (tried, Original, II and Ultimate III) though i wasnt getting the greatest results, the epoxy is actually easier to work with the veneer than titebond, the titebond always made the veneer curl as well. The shells with epoxy actually sound better also once finished.

The veneer is 0.6mm, I have found the techniglue epoxy flexs fine, i pre laminate 2ply sheets and roll them into the moulds and it has not problems even the finished shells will flex a little if you push the sides together, shell thickness ranges from 4.5mm-6.5mm usually.

How do you think the West Systems would compare

I apply techniglue to both surfaces, but as thinly as possible. Also, it needs to have adequate pressure applied - are you using a vacuum bag? It's good if you can.
You can tint the glue with powdered pigment such as brickies' ochre or red. You don't need much, and it will make any glue line less noticeable.

No vacuum press, I am building up the plys in the moulds, once positioned plenty of pressure is applied and maintain from the inside out. I have been using a fair bit of glue to make sure the sheets are well covered on both surfaces ensuring a good bond(once dry and out of the mould i trim off the excess and squeeze out then cut the shell to the desired depth), the colouring is a good idea though at the end of the day a tigher/less visual glue line is what i am after. wether it be with Techniglue or another epoxy hmm.

Thanks for the help so far...keep it coming

That could be the problem. I use as little as possible for laminating.
