Anatomy of the LIF Hunting Riser

Postby Bobmeister » Fri Feb 24, 2012 10:29 am

I have been asked to build two 14" risers and if I could do a build along at the same time. It sounded fun so here we go.... :)
These will be made from Cocobolo, Bocote, Black Phenolic and Maple
The risers will be 14" overall in length with 18-1/4 degree limb beds. This will give them an approximate 1.8# gain over limbs rated on a 17" riser.

Here are all the materials gathered up
Image

Here the pieces cut on the table saw to make the riser block sammich (wood is the bread and canvas phenolic is the meat)
Image

All glue surfaces are scratched up with a hacksaw blade To help with the mechanical bond
Image

I hate it when you go to clamp your parts together and they start sliding all over the place because of the Bow-Snot,so I put a 1/4" dowel in the corners that will be trimmed off.
Image

Epoxy applied and all clamped together. I then put them in the hot box with two 60 watt light bulbs this will keep them at about 80 degrees to set up over night.

Looking for information on LIF bows is what led me to this site!

I like the dowel idea.. I to hate the wood sliding around and it always seems to do so...

14" seems like a really small handle.. what is the advantage to such a small riser.. or is it just a personal prefrence?
God gave you hands, use them!

The title says it all ( Hunting Riser), a 14" riser will make a 55", 57", or 59" bow.


Got the blocks out of the oven and ran them thru the drum sander and then squared up the belly side.

Next I need to cut all of the accent pieces that will be laid up in the block.This is my lam ripping jig for the bandsaw, 1/4 turn on the red nob = .012" Image

Here are all the laminations ground to there various thickness's

I took my time and got a good fit and then double checked the dry fit.

Going to use the wooden dowel thing again to keep things from sliding around

Man Bob, your work looks so precise compared to mine :oops:

I love the grain pattern in those pieces of Bacote and Cocobolo. These risers are going to be beautiful. The Black Max limbs mediums are on order and a buddy has tied up the Flemish twist strings also! Like waiting on Christmas :D
With God, all things are possible.

Inspecting the blocks after glue up. So far so good....

Now I will grind them to clean off the excess glue and to the desired thickness (1.75")

Next I will layout the profile with my template
