I'm getting ready to do my first bedding job on my Sako 75 and I'm in a bit of a quandry trying to figure out how to place the front pillar.
Here's what it looks like:
From the center of the action screw hole to the rear edge of the recoil lug is approximately 0.154 (I don't have the best measuring tools, but it should be within a couple thousandths.
My plan has been to file a flat on the front pillar so that the recoil lug would clear.
Here's my question: The ID of the pillars I bought is ~0.300, which tells me that since half that is 0.150 I would have to file completely through the outside portion of it to get enough clearance to fit it. The pillar holes are not completely concentric, so I think i could find the fatter portion to place to the front and end up with some material remaining, but probably not enough to hold up.
There are other pillars available through Brownells that have 0.280 and 0.260 ID's, which by my numbers would leave me with 0.010 and 0.020 clearance. The action screw's thickness is something in the area of 0.220 (I misplaced my notes).
If I could have a few thousandths of clearance, would it be better to file right to the edge of the hole, so that I would have more thickness of bedding compound, or would it be better to try to get the pillar to sit right up against the lug?
Should I try to find a pillar with a smaller ID than what Brownells sells? How much clearance do I need between the ID of the pillar and the action screw? I have thought that it would be possible to have a pillar made that the threads of the action screw will barely clear, then grind off the threads that don't engage the action so that the screw would not touch the inside of the pillar.
I would appreciate any words of wisdom, or even of mediocre insight (beggars can't be choosers, right?).
