This will require GREAT care to precisely drill out the 5/8” holes that the Pillars will rest in

bullet

Check action for binding!  Make sure the action will easily go into the milled/drilled stock

Attach Pillars to the Rifle action

bullet

Check for fit

bullet

Attach barrel to vise with the action upside down

bullet

Make sure all will fit easily when epoxied

Epoxy the pillars to the stock

bullet

Use the 5 minute epoxy to hold the pillars in place.

bullet

Insure that the Pillars are epoxied solid before proceeding

bullet

Wait the amount time necessary for the epoxy to cure before proceeding

bullet

Wait at least 30 minutes or more

bullet

When complete check for uniformity of epoxy completely around the Pillars

 

 Bed the Pillar in place

bullet

Unscrew action from the pillars and make stock in upright position

bullet

Clamp the stock upright in the vise for this job

bullet

Mix Liquid Steel as prescribed

bullet

Apply Release Agent to the lug/action area

bullet

Keeping the stock upright for this entire process

bullet

Pour the Liquid Steel in the lug and tang area of the stock

bullet

Leave 1/8” from the top for the final Bedding material

bullet

Reattach the action to the Pillars with screws from bottom

bullet

Wrap surgical rubber to keep the barrel in place

bullet

Wait 12 hours for Liquid Steel to cure

bullet

This part of bedding the Pillars should be done with care and it will have not have a mess left behind

 

Inspection

bullet

Remove action from stock gently

bullet

Action should remove fairly easily

bullet

Remove the release agent from the lug area

bullet

Check the bedded pillars to insure adhesion and uniformity

bullet

If done correctly, this part of the job is fairly clean

 

 Mill out the lug area again

bullet

This time mill only ½” rear of the lug and 1/8” on the sides

bullet

Rough the surface of the Liquid Steel so that the final bedding compound has something to adhere to

 

 Bed Action in place

bullet

Apply release agent to entire working area of action

bullet

Apply release agent to pillar screws

bullet

Apply “10 mil” pipe tape to barrel (forward of lug to barrel contour, approximately 2 wraps)

bullet

Apply electrical or masking tape around the lug.  Trim with razor so that the front and back of the lug is not covered, only the sides of the lug.  (approximately 3 wraps)

To a complete check to make sure that all of the above has been done and ready to go!  This is a critical moment and you want to get this right!  TAKE YOUR TIME!!! 

bullet

Clamp the stock to the vise, upright, make sure that both pillar screw holes are accessible

bullet

Mix Putty Steel (Devcon), Marine Tex or equivalent

bullet

Stir it well

bullet

Apply bedding material to lug area, agitate mix, insure NO air bubbles

bullet

Apply bedding material to all areas of stock contact

bullet

Apply bedding material to tang area

bullet

Apply bedding material to the receiver action and smooth (Very Important)

bullet

Insure all surfaces where there will be contact has bedding material

bullet

Insure that the bedding material was applied as not to create air bubbles

bullet

When satisfied or if bedding material starts to harden…

 

bullet

Run the pillar screw (tang) from the bottom, start screwing the tang area in first but support the barrel from sinking into the bedding.

bullet

Screw the lug area next and slow tighten, letting any trapped air bubbles evacuate the bedded area.

 

bullet

Bedding material will ooze out in great quantity!  Do not be alarmed or panicked!

bullet

Clean up the bedding material with Q-tips

bullet

Make sure there are NO MECHANICAL locks created with material going over the action or tang area!
