How tight does the fit need to be for a good glue up with Unibond 800? I have my ipe prepped, and the bamboo is shaped, hand planed, and sanded. When I put the two together, they are very close, but there are a couple tiny gaps along the length. Not enough to see through, but the bamboo isn't perfectly flat like the ipe is. Since Unibond is gap filling, how close is good enough? Been working on trying to sand and hand plane, but I'm only getting marginally closer to perfect, and I'm not sure I can get the bamboo much flatter.

Just put plenty of glue on and it should work out.
I don't worry and never dry fit the pieces.
I do occasionally have a small gap after clean up.
I use a mixture of super glue and saw dust to fill and sand smooth.

Cool thanks!

If you can't see light thru it, I'm sure it's close enough for Unibond. I dry fit mine and like to slide the bamboo 1/2" or so past the edge of the belly lam and see how the surfaces match up that way, too. A lot of times a tiny gap that I see along the edge will be gone when I cut the bow to its profile, anyway.
-
Put a good coat of glue on both surfaces and go for it. Clamp it every two inches. Pad the boo side so the clamps don't mar it.
-
Gluing both surfaces is key. As Roybert mentioned.
-
I said I didn't dry fit, a little,explanation. My bamboo is run through my thickness planer after being cut to shape.
So it is flat.
I have a little more problem when fitting the handle like Roy and others shape theirs. So I use flat 1/4 inch or less pieces and stack them when I glue up.
-
Mac, all it takes is time and patience my friend. I can fit a riser up to a bow, perfect in 10 minutes.
-
Try it sometime, just don't worry about time.
-
Roy I have tried. I guess maybe I try to make it too perfect.
I have some wood I'd like to make into a,solid handle.
So will give it a go again.
-
Make it 1/4" wider than the bows width at the riser. Same length as you need it too be. Lay the bow onto the side of the riser block and trace out the profile. Cut it out and fit it up. I know you can do that Mac... Heck if I can, you can. I'll even bet ole Kenny M could do that.

LOL

Bowhunter15. Did You get the glue up finished?
