Apex looks like you beat me on some of them. I was not sure on a couple. Kenny I sure like that Bacote I may have to talk to you about some more lams if you have some with a lot of figure. I am also going to build a bow with some red elm cores that I may need to get from you.

Kevin L. · « **Reply #4 on:** March 20, 2009, 01:57:00 PM »

I'm no bowyer by any stretch of the imagination, but I'll give it a go.

OK heres the scoop:

Bocote,cherry,osage,maple

A-boo,hickory,walnut,red cedar, red elm

Now then,I weighed a .060 parallel,1.5" x 36" >>>---------------->

Name the heaviest and lightest in mass weight ??

And the stiffest and most limber?

Lewis Brookshire III · « **Reply #9 on:** March 20, 2009, 08:57:00 PM »

Heaviest= Osage
Lightest= Red Cedar

Stiffest= Boo
Limber= Cedar

Just a guess, I havent worked with some of those

I need a new monitor BAD!

monterey · « **Reply #11 on:** March 21, 2009, 12:11:00 AM »

Heaviest: Bocote
Lightest: Red Cedar

Stiffest: Hickory
Limberest: red elm

Total SWAG. Only ones I've ever worked with is maple and elm

Heres the scoop on the wood tests:

I weighed a half a lam cause my grain scale goes to 500 gr.,then doubled it to show what is in 1 limb,less what is cut off in shaping....

Then clamped each one to my bench with 12" hanging out in midair. Then measured to the floor,clamped a 1" spring clamp on the end of it and remeasured to the floor. The difference is the amount of deflection for each wood.The clamp weighs 2.6 oz. on my postal scale.

Wood type...Weight/grains...Deflection/"

Hickory-----665.8-----------2 1/8"

Walnut------640.6-----------2 3/16"

R. Cedar----478.0-----------3 3/4"

Maple-------758.2-----------1 1/2"

R.Elm(edge)500.2------------2 1/8"

Bocote------875.6-----------1 7/8"

Cherry------630.4-----------3"

Osage-------678.0-----------3 1/16"

Natural
Actionboo---636.2-----------3"

Some of these rated about where I thought,some were a surprise. Figured A-boo would be lighter in weight and osage would be stiffer.

What do y'all say?

monterey · « **Reply #13 on:** March 21, 2009, 07:58:00 PM »

Not surprised at the weights, but very surprised to find maple to be the stiffest.

defiant · « **Reply #14 on:** March 21, 2009, 10:40:00 PM »

Kenny, were they all measured with the same grain orientation? I am also surprised to see maple on top.

kennym · « **Reply #15 on:** March 21, 2009, 11:01:00 PM »

I tried to find scrap stuff that was qtr grain,the red elm is edge,the hickory and red cedar fairly flat grain,the rest is pretty much quartering grain.

That does seem stiff,I'll recheck it tomorrow. Already rechecked the red elm and a-boo cause it didn't seem right.

I didn't expect the elm to be that light in weight, or the osage to be as limber as that! Good stuff Kenny!

bretto · « **Reply #17 on:** March 22, 2009, 08:24:00 AM »

Now the real question: does the stiffer or more limber lam make a better limb?

I only ask this because I hope to build a bow this year.

kennym · « **Reply #18 on:** March 22, 2009, 09:05:00 AM »

Marty, I was surprised by several of these. May have to cut a new batch of test strips when I have time....

Brett, I would think the wood with the lightest/stiffest properties would be best. I'd like to build 2 identical bows,1 with all red elm edge grain and 1 with actionboo just to see which is best.

I am bettin on the red elm. Bob
