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.

If you have a lathe, you will of course, use it to trim these pillars to length.

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.
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.

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.
