The glue up profile looks nice, I think you will like the out come:)

Zradix

Well thank you Roy.

I sure hope so.

You've been a GREAT help man.

Thank you!

..just hoping those glue line are good..no crushed boo..

OH..I did take some time and contoured some of those pressure blocks for the thicker part of the boo where it had more of a curve to it.

Thanks for the tip.

Start saving the scrap pieces of boo and cut them into 2 inch pieces. Or use a piece of boo that's not so bow worthy and make a bunch.

Lookin awesome Zradix can't wait to do mine though...i'm gonna need more clamps...hmm.

Zradix

if you have the $$$ I'd really recommend some decent c-clamps.
There more of a pain to use but I personally felt more secure where I used them.
..but for most of the bow you're only pressing that thin pc of boo down.

The spring clamps were $1 ea at home depot.

i'll be doing a tri lam maple between hickory so probably need the c's for the whole thing

alteredbeast

btw where did you place your power lam in the bow?

Zradix

I plan on using a 9" handle.
I made the PL 3/16" thick and 12" long.
The handle and PL are in the center of the bow..I guess some offset..but that seems way to complicated for my simple mind..lol

It's between the ipe and boo.

LOL mine too. I have seen people on here put a lam between the backing and the bow not sure if thats what they called the pl...Ithought it should be between the handle and bow.

alteredbeast

cool that answers my question. Sorry I'm just tryin to learn as much as i can here.

Zradix

I think you can do it either way.

Basically you're just trying to stiffen the area where the handle goes so it doesn't want to flex so easily...takes some pressure off the handle glue joint so it isn't as prone to pop off.

Other guys don't use one at all..like Roy.

I just wasn't sure enough of my knowledge of how things were going to bend to not add a little extra "cushion" to my design.

here is a little better pic of it's location..
where the boo looks thick is the PL..it's osage

hey..just remembered one reason I figured was the best reason for putting the lam between the back and belly....

it was going to be a hell of a lot easier to bend the boo to the taper than any part of the bow...

dooo...dooo....dooodoo...dooo..doo... dooooo! (to the tune of jeapordy theme)

Echatham

you don't need to wait til 1 AM.... you can take it out now.... i know you want to....    :jumper:

Zradix

took it off the jig this morn.

..not super happy..
Tips are twisted/bent over 1/2"-3/4" from center.
I have no idea how this happened..I had the jig marked on center and then marks where the outside of the wood should lay.

..hell..maybe the wood just wanted to bend a bit after being cut..?

So there's going to be some straightening to do.

My glue lines are fair to good over most of the bow.
There are a couple spots where there glue didn't seem to get out to the edge.  Not sure how that happened either..
I had a LOT of glue all over this bow...not taking any chances type mentality..but that didn't work out..lol

One fade looks really good..the other...eh..I hope it'll be ok.

After I get the glue off and sand down the edges a bit, I'll be able to see how the glue lines really look.
At this point I think I'll be buying a tube of superglue..darnit..didn't want to have to do that.

She had a fair amount of springback.
Here the only pic I have at the moment..
Just gonna keep at it and see what happens.
