I have some 1/8 and 1/4 g10 sheets does anyone see a problem with laminating pieces together to get a thickness I want. For example, will glue show through during the shaping process ect. Or just go buy some thicker stuff.
Thanks Jerry
 
Nope, do it all the time for aesthetic reasons. I generally use a quality CA glue when laminating. The chance of a seam is less likely than a thicker epoxy but epoxy works too.
 
I've only used epoxy to laminate G10. I laminated some sheets together in the past, once. This was 4 layers;

I haven't laminated sheets since then, just handle sized pieces. If and when I do it again I'll avoid the screwups I made last time. This knife and a couple others I made from the material had a few air pockets open up between layers, super tiny and not a structural issue but annoying and time consuming to take care of. Also, my sheets slid apart a bit so I didn't get as much material as I could have.

1. coat every surface that will touch another with a very thin layer and make sure there are no voids
2. wiggle the pieces against each other to make sure the epoxy is consistent between layers
3. tape or otherwise hold the pieces in place so they don't slide around

I put my granite slab on top to distribute the weight equally across the sheets. Waxed paper top and bottom to keep the epoxy from getting all over the place. I put a few more things atop the granite slab, I think maybe put a bench grinder on there too- maybe 65-70 pounds of weight. It was all done on a finished concrete floor, but I think I should have put down something else first that I knew would be flatter than the floor
 
Glueing two of rhe same pieces on top of eachother will show a a line.
But different colours/textures will look good
 
Too much pressure or clamping can create a glue starved joint, especially on very smooth surfaces. Avoid too much weight or screwing down C-clamps as hard as you can. Light weight spring clamps are best for most handle tasks.

Sanding mating surfaces dead flat to 220 grit creates just the right surface for a good joint.

Thin film resins like CA are excellent for laminating things like G-10.

Even clamping pressure is much more important than high pressure clamping.
Make a simple book press style clamp from some thick plywood or 1/2" thick metal plates.
See the below image to get an idea of how it goes together.

I love the wat that Lantayd hole looks Kinda trick from my straight hole through the blank . Would you have any issue with me using this idea on one of mine?
Thanks Jerry
 
Do it all the time. I use epoxy coloring agent in a similar color normally to hide any ‘seam’.

I didn't invent it, so I got no claim to it
 
but, y'know...don't copy it exaaactly...
it's cool to see things done a different way by someone else and then modify that idea to suit your own thing. I'm convinced we're all doing that most of the time generally speaking. Insert meme here;
 
Yep. This was for an auction piece done to benefit a Veterans charity.
