Best $5 change to CFX (adjustable cheek rest)
« on: May 02, 2008, 01:22:55 PM »
I have always liked the look of the adjustable cheek rests. So I decided to try and put on my CFX stock. I did the following

- mill top of existing CFX stock flat
- mill one side of 1 1/8" dowel to have a simlar sided flat
    I really used a table saw and a clamp to hold the dowel and prevent it from twisting. The clamp was flat against the fence for the cut.
- drill two 1/2" holes (3rd hole was a mistake) thought both the dowel and stock at the same time.
    I drilled one hole then put the riser in the hole while I drilled the other hole to assure that they lined us when I was done.
- glue 1/2" wood dowel half deep in the 2 holes in the 1 1/8" dowel (fill the mistake hole completely)
- sand the dowels to the level of the big dowel surface.
- glue 1/2" OD stainless steel tube into the big dowel
    I let it dry sitting in the holes in the stock to assure proper alignment
- cut a slit (3/32" wide) between the holes in the stock and about 3/4 to 1 inch past each end.
    I put a 3/16" hole at the outer ends of the slit to relieve stress when clamping on the risers
- drill a cross hole to allow bolt and thumb wheel to clamp between two holes in stock
- counter sink for head of bolt
- counter sink for face of thumb wheel (to prevent side load on bolt and snapping bolt)
- assemble as seen below.
- adjust as needed WITHOUT needing any tools.
- enjoy shooting with a perfect weld each and every time.

pieces after first being milled and drilled. Note the big opening to the inner air space. I am not sure what to do about this? any ideas?



Test fitting (note the mistake hole)...easily filled in later...


Finished and test fired. It is AWESOME. this is an AMAZING improvement. Well worth the 2 hours and $5.....really worth much more!!!

You might be able to use some kind of putty-like epoxy on that hole, then sand it down to a smooth finish.

Dang Martin...:) What have you done to  your beautiful CFX...?  Just kidding.. Hey that is a great idea but I did not remember you having a problem shouldering your CFX when you were over for the shoot.  I have an idea for your stock to cover up the milled area if you have not already devised something. Let me know.

Nice and great idea , maby thin sheet of alumunum cut to spec's for the flat area on top. Drill your riser holes and epoxy to the top. It will seal the top and keep the stock seam from splitting with a finished look. Or a sheet of black plastic with the same spec's but if the alumunum was used you could shoot it flat or matt black. Again nice work and thank's for sharing. :) Ed

I did not have trouble shooting it because I had practiced enough to use the cheek rest as a chin rest. It is much better to have a cheek rest...

If I had it to do again I would not mill down the stock, but instead use a jig to hold the pieces together. I milled it down this time to allow me to hold them together while drilling the riser holes.

I need a way yo cover the hole that still allows the opening to flex so it can still clamp onto the riser posts. I was thinking last night that I could make a spacer piece that when between the stock and dowel that was the correct height and covered that holes....but then I lose the adjustably....that would be not good....maybe I just need to try again on another stock without milling flat spot on it.

I could put 12 inside the 8 ring consistently from 20 yards before. sitting in FT position.

Today I have been putting 8 of 12 inside the 10 and the rest of the 12 inside the 9 ring. This cheek rest is a definite improvement. It might not look the best but it work wonderful.
