No. 7. Machine "Bed Heads" Pillars to Length

All "Bed Heads" pillars for M-70 Winchester are longer than necessary, to allow custom fitting for each rifle.

   Note, this same process also applies when it is necessary to shorten the Remington M-700 ADL front pillar to fit a custom stock, or a custom front guard screw escutcheon.  Just remember, this time it is the Lower end of the pillar that gets trimmed.

 Picture #1

   If you have a lathe, you will of course, use it to trim these pillars to length.
   Picture #1 shows a dial indicator being used to measure the length being trimmed from a pillar.

 Picture #2

   If you do not have a lathe however, you can still do a very nice job of machining these pillars to length, and square, to match the flat bottom of the M-70 receiver.  This set-up requires a drill press with some type of adjustable quill stop, a drill press vise with 1 "prismatic"  jaw to locate the pillar vertically and a 1/2" counterbore with a 5/16" pilot.

 Picture #3

   The "Bed Heads" pillar ID is reamed to .312 (5/16") this reamed hole provides an accurate fit for the Teflon sleeves during the pillar installation process.  It also provides an accurate fit for the 5/16" (.312") pilot on the end of the counterbore. These counterbores and pilots are available from MSC and other industrial tool suppliers.

   The counterbore pilot has been lowered into the pillars ID.
   Turn the drill press on and continue to lower the quill until the stop has been reached.

 Picture #5

   In picture #5, The pillar has been cut to length.  The accurate fit between the pillar ID and the counterbore pilot has made it possible to achieve a nice smooth finish on the end of this pillar.
   All that is necessary now, is to de-burr the outside edge.
