Smooth, rough or toothed? It s always a good idea to read the directions on the glue. :) Jawge

Not picking on you, BJ, as this is a common belief. There is no way that the thin lams can bend once glued into a block. As long as the glue is as stiff and strong as the wood (EA-40 certainly is) that laminated block will behave exactly the same under load as a solid block of wood of the same dimensions.

I suspect this is the reason people have more success with laminated handles. It is definitely easier to get good glue lines with thinner laminations that can conform to the other side of the joint. Laminated handles also look great when contrasting woods are used.

Smooth On's technical info says to prep lams by planing or sanding with 120 grit sandpaper, which I don't think anyone does. I use 50-60 grit on my thickness sander just because 120 would go far too slowly and would clog and wear out continuously. It might be worth block sanding the lams with 120 grit after the thickness sander but I haven't tried that yet.
Here is a link to the EA-40 Technical bulletin that specifies 120 grit for prep: http://www.smooth-on.com/tb/files/EA40.pdf
On page 2 of the bulletin it has specific bow making instructions. It says to plane or lightly sand the lams with 120 grit paper.

Her are some pics of the handle before the glued on piece.

Close to enough wood for the handle not to bend I think?
