I'd like to pillar bed a stock, cutting and fitting my own pillars. Anyone have a source for the aluminum tubing needed and perhaps recommend the size and or hardness? The stock is a Win
Mod 670.

I believe the last one I did was with 3/4" round steel cold rolled this allowed me to fit into stock flush and counter sink the action screw into it. I drill a couple thousandths over screw size, bed and then open up the screw holes a little. Makes alignment easier. I also cut a shallow thread down the out side around 20 tpi or a little finer. Not super deep but .015 - .025 on a side to help carry epoxy thru and give a bond area.
I have made my own Pillars out of 1/2" , 5/8" or 3/4" Brass or Aluminum Round Stock from the local Hardware store or Scrap yard.
I just drilled out the center to make the Sleeve, then turn the outside to whatever shape or Size I needed.
I would Contoured the top edge to fit any round receivers, and countersink the bottom to fit the action screws.
I didn't find that Hardness of the material did not matter that much.
The action screws will not exert enough force to Crush the material, and being all one unit, ( if tight ) will not batter under recoil.
I made a couple from 1” aluminum scrap turned down to 9/16” for a Remington 700 plastic stock.
Put some 1/8” grooves in so the epoxy had a good grip on them.
Brownell's is a good source for most gunsmithing supplies, including pillar bedding. james
I used a brass coupling meant for air hose. It was the right size for a savage .22.
I used an X-acto handle. They made some fat ones, 1/2" diameter, perfect for pillar bedding. Can't remember if it was already drilled through or if I had to finish drilling the inside, but I chucked it in my drill press and cut grooves around it 1/4" apart.
Got a .22 .30 .32 .357 .38 .40 .41 .44 .45 .480 or .500 S&W cylinder that needs throats honed? 9mm, 10mm/40S&W, 45 ACP pistol barrel that won't "plunk" your handloads? 480 Ruger or 475 Linebaugh cylinder that needs the "step" reamed to 6° 30min chamfer?

Yesterday I cut this 4 pound Bartlein barrel down to 2 pounds 4 ounces. It is going to be a lightweight 260.
Making a pillar with 1/2" Aluminum alloy round stock.
Side cut with 1.25" end mill for a pre compressed V block like fit the 1.3" Remington 700 receiver.
Drill a hole for action screw.
This is a used stock. You can barely see I have drilled out the previous owner's 1/2" Aluminum pillars. What you can't see is how I also chiseled out where he bedded around the recoil lug.
I roughed up the outside of the pillars to grip the epoxy better.
I globbed Devcon Plastic Steel Putty on the pillars and behind the recoil lug.
The correct aluminum rod or bar stock for machined parts is 6061-T6. This is the most common heat treated aircraft and military specification aluminum used in industry.

You can cut them from Threaded Lamp Rod, and they work just as well as anything else. https://www.lightbulbs.com/product/w...hoCi_UQAvD_BwE
Brass bushing's from Lowes, Rural King etc. Come in different size's .

You can buy actual pillars from Brownells for less than $15.00. Time is valuable so unless your time is very cheap, that's probably the easiest route.
A bedding pillar is not a complex part, so if you have the time and want to make your own, that's certainly a possibility too.
Some aluminum or brass bar stock, a lathe or even a drill press and you could make your own.
Online Metals is one place you can order different sized pieces of aluminum and don't forget the neighborhood junk yard. Frank
Ive made several from 1/4” steel brake line from the auto parts. No machining, cut to length with a tubing cutter, hit the outside with a grinder or file and epoxy in.
