G10 risers

[Buemaker]

Looking good.

[Shredd]

Looks Great...  A lot better than it looked being glued up...

[Bvas]

Now you need some Big Jim Dark Timber arrows for it. It looks really nice.

I plan on it!!!

Gotta figure out what spine it likes first.  Probably gonna be 340s with a 250gr VPA up front.

Sweet bow.

[Bvas]

Finally starting to get some time to do a little shooting. Got some arrows tuned in. The dark timber bow likes the new dark timber arrows

And that's 20yds, not 2ft........Roy

Nice Bvas

[Flem]

Nice shooting
That  thing has some mass to it. Do you know how much it weighs?

[Bvas]

Flem, its 58" with 18"riser. Total weight, string and all is 1.77#.

Doesn't have quite the mass I was hopin for. I may have to build another.  If I do, I'll probably go to 60" and use more Osage in place of some of the walnut.

Yes G10 is heavy, but even if you have used a riser made entirely of G10, it just won't add up to "Heavy" in a longbow.


G10 - 110 lbs per cubic foot
phenolic - about 85 lbs per cubic foot (slight fluctuation depending on substrate)
Macassar or gabon ebony - about 72-75 lbs per cubic foot.
walnut - 38 lbs per cubic foot
osage  - 54 lbs per cubic foot

Imagine a longbow riser block that is 1.5" x 1.75" x 18" = 2.7% of a cubic foot... or :
G10 - 2.97 lbs
osage - 1.49 lbs

but the above block is whole and an actual longbow riser block is about 60% waste or more depending on design.
That now makes the weight of the finished longbow riser:
G10 - 1.2 lbs
osage - .58 lbs 
So, after all that math, there is only about .62 lbs or 10 oz difference between a solid G10 and a solid osage "completed" riser. That is less then a quiver and about 3 arrows.
Saying all that, it is still desirable added weight.
