I have a previously bedded rifle with the adjustable length pillars. Now they seem kind of “Mickey mouse”. Should I remove them an put solid ones in or just leave them in place?
Does it shoot?
Careful, you might hurt my feelings. Keep in mind you are tightening a screw to inch pounds. I assume they are something like this?Now they seem kind of “Mickey mouse”
If it is always going to be an area of concern to you put in solid pillars like you are familiar with.Right now it is in the process of being re bedded. I want it to shoot well.

Once you know the height you need, put a little Devcon on the threads if you are mixing some up, and they will be SOLID.

As an experiment I have necked the action screws down like a connecting rod bolts for additional clearance, 1/4"radius at the ends of the relief and polish with 400 paper. Take the necked area down to around .225. Still plenty strong for 30-60 inch pounds of torque."You only want one recoil bearing surface in a bolt-in gun. And it better not be the action screw(s)!"
Good shootin'. -Al
An easier solution is to make the pillar I.D. 5/16" and glue a 5/16" O.D./1/4" I.D. sleeve in the pillar. That way, the action screws are perfectly centered and you have .031 clearance all around the action screws when you remove the sleeve after the bedding cures. -AlAs an experiment I have necked the action screws down like a connecting rod bolts for additional clearance, 1/4"radius at the ends of the relief and polish with 400 paper.

I don't ever allow hard contact between the top of the pillar and the action. A good amount of bedding material should be on top of the pillar. -AlToying with the idea of using 1/4 IDx3/8 OD "o" rings between the pillars and action when bedding so the action can be bedded in one step and avoid contact between the action and pillars.
I have done it by gluing in the pillars separately and spacing them 3/16-1/4" below the action with spacers and then removing the spacers and bedding the action. Have also just counter-bored the top of the pillar with an end mill after bedding but don't like the void that leaves. Thinking of ways to bed them in one step with the action and have compound between the pillars and action. Making the pillars from the bedding material may be the easiest way to accomplish this.I don't ever allow hard contact between the top of the pillar and the action.
