I wanted to show off my first attempt at making a Tri-lam bow. The bow is 65" NTN and draws 55# @ 28".
I glued up a combination of a bamboo back, white oak power lam, double tapered maple core, and a slightly tapered osage belly lam. I used a thickness sander and a pair of Kenny's taper sleds to sand the maple and osage laminations. I then spliced the maple and osage laminations together before gluing the bow up. The handle is made up of thin laminated strips of hickory with a few pieces of jatoba on top for a mix of color. The limb tip overlays are Ipe.
The top limb is 1/2" longer then the bottom.
The bow was glued up with a couple inches of reflex and deflex. The finished bow lost around 1/2 of the reflex and ended up holding 1" rested reflex and only takes 1/4" set while shooting.
Tillering was a bit difficult and I really took my time to ensure I did it correctly. Both limbs have an even tiller for my 3 under release. The bow draws smoothly and shoot well.
The bamboo back was stained with leather dye to create a natural camo. I then stained the rest of the bow with black walnut dye to darken up the osage and make the grain stand out more.
The bow is scribed with the phrase " Aim Small, Miss Small"; which was a phrase my grandpa liked to use.
The Cross on the bow reminds me of everything I have to be thankful for.
Two coats of amber shellac were used to seal up the bow before I applied 6 coats of water based spar.
The bow was finished off with a leather grip and arrow rest and a nice little piece of beavertail leather on the shelf.
After shooting the bow 75-100 times I decided to Chrony it. Drawing 55# at 28", I managed to attain 175 fps with 565 grain arrows and 170 fps with a 601 grain arrow; making this the fastest bow I have built so far.
The bow was a fun challenge to build and is a joy to shoot. If anyone has any suggestions on ways I can improve please do not hesitant to tell me! I definitely see more Tri-Lams in my future!
