    Can you give me your step by step processes for making a multiple material step handle? I have tried gluing up the parts prior to attaching them to the handle and I keep having issues with G2 epoxy coming undone.

    Latest was a handle made of zircote, g10 and white ebony. I expect my problem was the ebony being oily and I wiped it down with acetone before gluing but it still came apart when sanding (not due to heat).

    I had asked before about gluing to a liner before and the answer was no but it sure seems like having that support would help. What am I missing?
    Thanks

    Ebony, wipe down with acetone then alcohol before gluing.

    All epoxies need a minimum grit surface finish to bond properly, 80 grit is a suitable degree of sanding.

    The joints will be weak until bonded to the steel but you can help keep it all together with very small pins. Toothpicks will work like a charm

    Thanks. I didn't mention it but yes I am sanding all surfaces with 80 grit as well.

    Sorry to ask the obvious, but why not try putting them together with a liner anyway? Just because others don't do it, doesn't mean it won't work better for you.

    No reason. Also thought about doing it in thin pine or some rigid cardboard that can be sanded away.

    I also thought about making them bigger for more glue area, cut them in half to make a scale and then sand down the cut sides after they are glued to the handle. Just not getting enough support or bonding the way I'm doing it now.

    [​IMG] [​IMG] I build them both ways with liner and with out. First make your two front pieces the same and finish the front. Then you work back from there . Get a real flat surface and put a piece of wax paper down and build out that. Clamp all pieces down good and a clamp from front to back.When the glue is dry you should just clamp it to your knife handle and drill your pin holes in one piece first then line everything up and drill the other piece. Go easy . You shouldn't have to work at them till after you glue them to your knife. I cut all joins on a 45 it gives more to glue to . You can drill a pin hole through all your pieces and put a pin through them as you glue them up to to make the join stronger.
    With a liner it's much easier to do . Just make sure both piece of each is the same thickness .Just do the same but glue them on a liner. Just make sure both sides are lined up before you drillthe holes . It's very painful if you forget lol to line things up before you drill the holes . Been there. This is two of what I have done.
    Lock the door turn of your phone before you start lol
    Next time I do some I'll take more pictures .
