Need some help/ideas in securing bamboo or sugar cane stocks for knife testing

Deer leg bone is more dense than our arm long bones are due to weight on them as they grow. Pig leg bones, same same per a slaughter house, and the bones aren't long enough measuring just 4-6" in length.

There are four types of bone in the human face and the length of treatment for placing
and restoring implants with a "tooth" and crown depends on which type of bone
the
implant is placed in. Implants have to integrate with the surrounding bone bef
ore a
tooth and crown is placed on it.
Type I bone is comparable to oak wood, which is very hard and dense. This type
of
bone has less blood supply than all of the rest of the types of bone. The bloo
d supply is
required for the bone to harden or calcify the bone next to the implant. There
fore, it
takes approximately 5 months
for this type to integrate with an implant as opposed to 4 months for type II
bone.
Type II bone is comparable to pine wood, which isn't as hard as type I. This
type of
bone usually takes 4 months to integrate with an implant.
Type III bone is like balsa wood, which isn't as dense as type II. Since the
density isn't
as great as type II, it takes more time to "fill in" and integrate with an imp
lant. 6 months
time is suggested before loading an implant placed in this type of bone. Exten
ded
gradual loading of the implant can, however, improve the bone density.
Type IV bone is comparable to styrofoam, which is the least dense of all of t
he bone
types. This type takes the longest length of time to integrate with the implan
t after
placement, which is usually 8 months. Additional implants should be placed to
improve
implant/bone loading distribution. Incremental loading of the implants over ti
me will
improve bone density. Bone grafting or augmentation of bone are often required
. Bone
expansion and or bone manipulation can improve initial implant fixation.

The ulna and radius bones are type two bone. I think 1.75" between two pine dowels may just work to duplicate the bones in the forearm.
