Reflex/Deflex Bamboo backed Osage Tri-Lam build-a-long

[wytetale]

I have my Birds eye Maple block ready. I laid some maskingtape over it and and drew my centerline on it. Now I am ready to trace the profile of the bow on it and cut it out.

Now it is cut out so I am going to sand it in so I get a really good fit to the riser, I have a pretty good fit now.

Now I am going to trace the same arc again about a 1/2" down and cut it out agian so I can  put an accent strip of osage in the riser

Here is a pic of the riser now all ready to be glued up.

Here it is all glued up till tomorrow. We will cut in the fades and make the lamination for the belly and get that all glued up then.
We also glued up another bow like this today but not a tri-lam. It is a 60" and it has a Bacote riser. Post some pics of that one tomorrow,

This is a very good build-a-long. I am learning much by following it. Thank you.

[adb]

Thanks very much for this build along! There is much to be learned here.

Thanks for doing this wytetale.  What wood are you using for the power strip?

[radius]

why is that piece called "power strip" or "power lam"?  It seems mainly to be a handle thickener...i could use some advice here, thanks.

[wytetale]

The power strip is made of maple also, I usually try to match it to the riser wood. The Power lam or strip acts as a stiffener for the riser. It extends 2" past each end of the riser. It strengthen the limb so when you draw back it helps to eliminate some of the stress on the riser. On this type of design the riser has a deflex built in to it so there ain't much stress.Thats why I make them a 1/4". On the other type of form that I use where you glue up a square block for a riser I make my power strips 3/8".They seem to work I have never had a riser pop off or come loose.

awesome, that makes perfect sense.

Thanks

Had to do my honey do's today. Thurseday we will cut the fades and glue the belly lams on.

This is good info... I'm watching closely and hope to try one of these.  Jim

[wytetale]

Monday and Tuesady will be putting on the belly lams and hopefully tillering it out.

Wytetale, where are you?  We want to see how this goes!

[radius]

is that little jointer a good tool?  i was thinking of picking one up, to make pre-tapering easier...

[wytetale]

Radius, that little jointer is great, does a really good job.
