Measuring Pillars

Getting ready to pillar bed and full action bed a Remington CDL stock for a light varmint barrel, so I thought I would ask the rest of you how you measure the pillars.

I will be measuring the pillars after I remove the wood from the inletting, leaving only a small amount on the rear tang area and using some tape on the barrel on the forearm to center the barrel and give me a good center line running the length of the rifle. I check the depth from the bottom of the stock at the trigger guard action screw holes to the bottom of the receiver 4 to 5 times to get a consistent measurement. That will be the measurement for the pillars plus adding 3 to 5 thousandths to insure good metal to metal contact with the trigger guard and the bottom of the receiver.

What are your techniques?

    I'm pretty easy on this.

    Mount pillars to action with action screws. Insert into inletted stock and make sure they protrude out the bottom at least 1/4". Devcon into place and cut/sand pillars flush with stock. Since I only do this on stocks I am building, I finish them together for zero clearance.

    See? Easy.

    Which tools/machines are you using to cut/sand the pillars flush to the stock?

    I have a set of calipers, drill press, files and the such. No lathe.
    In another member's video (Phil) he did the pillars with a drill press and it is very doable. Chuck the pillar, use a hack saw blade to cut and then sandpaper to fine tune.

    Come on Guys. Am I thinking right or way off base?
    Just want to be sure to do it right the first time.

    Re: Measuring Pillars

    After the pillars are in the stock, I cut them off with a band saw, if necessary, and sand flush with a rotary drum in the drill press, and finally sand by hand with sanding block until satin finish.

    I try not to start with too much extra so I don't have to wrestle with them after.

    I usually start with the pillar pushed through the stock and pencil mark them about 1/4" long. Trim at band saw,

    Next I counterbore for the stock bolt head (1/4 X 28 socket head cap) so it sits just below the surface of the stock once bolted to the action.

    Again, this is when I am building the stock, so I don't mess the finish up as it is not on yet.

    Thanks Larry.
    I have some aluminum tube stock that is 3/8 OD (aircraft grade ) and will have 25 thousands clearance of each side of the action screw once the screw is centered in the pillar. Is that enough?
