Over the last two weeks I bedded one, and this is how I did it.
I cut pillars on the lathe from 1/2" aluminum alloy round stock and then mill the ends with a boring head to get a radius that matches the round receiver.
I put the barrelled action upside down in the barrel vise and level it.
I put the pillars on and pre compress them with the action screws.
I set the space between the barrel and stock and between the action and stock with layers of tape.
I put Devcon on the pillars.
I put the stock over the pillared action and wrap surgical cord around them to bind them together.
I level the stock.
After the pillars have cured, I measure the volume of the recoil lug well and the volume of the recoil lug. I calculate how full to fill the recoil lug well with Devcon.
I get the rifle right side up, up in the air, with the recoil lug well filled with the right amount of Devcon, and then I tighten the the action screws.
When done the barreled action only touches the stock at the two pillars and the back of the recoil lug.
The action screws should be such a low compliance connection that they go from first resistance to maximum torque in 10 degrees of rotation.
The barrel should sound like a tuning fork when smacked with an open hand when the rifle is supported at the wrist.
A $109 Boyd's tacticool stock, a $114 Lothar Walther 223 barrel blank, and a $240 Sav action made in 1988 shoots it's first 5 shot group at 100 yards.
