Full lenght tapered laminations?

[Buemaker]

I have been thinking about giving this a try.
On a straight platen glueing two 36" tapered
laminations with the thin ends butting in the
middle, then placing a parallel lamination on
top of this and then run it through a lam grinder. Does anyone know if this will bring
out a satisfactory result?
Thank you.  Bue--.

Bue I've done something similar by placing the thick ends in the middle so when a parallel is placed on it and sanded the ends are thicker then the middle. This allows the mid-section of the limb to work more and stiffens the tip and fade area. Never tried it the other way.

Bue...not certain what you are trying to achieve.
In other words..why ?

Might be a great idea but I don't really follow.

Most bowlimbs are tapering towards the tips so instead of using two separate tapered lams one could have one continuous strip that tapers towards the tips.Does this make sense? In a take down bows this is of course not an issue.

Makes sense to me if you have a drum sander with a nice sized bed and pressure rollers to hold everything down should work OK. If you do it let us know how it works.

So you are making one piece (72" or so) laminations ?  I see.  I am barely good enough to make 36" single plane laminations.  You are already way over my abilities.

A concern I see is..typically (at least in my longbows) I am using a fairly thick taper(.150 or better, mainly better).  How are you gonna get that stock piece to bend and stay bent as you feed it thru the grinder if the platen slopes in toward the center ?  

Please show us results if this works for you.  I would love to learn another way.

Hello again.In order to make it work with such a platen I beleive BenBow is right, You will need a lam grinder with spring loaded pressure rollers. Most store bought lam grinders have that I think. Here is one I posted that I had made, it has no motorized feed system though.

You are killing me! You call that home made?

That is awsome!
I've used one of those fabric and foam adhesives in a spray can to attach sandpaper woodblocks,etc. I wonder if it would work on high speed setup?
