I used aluminium tube from B&Q, woodies stock it now. I bedded the trigger guard and pillors first.

The action screws were 6mm, so I used tube that had an internal size of 6mm. From memory I drilled the action holes in the stock out to 10mm. That way I got some epoxy down the hole as well.

I don't know, it was whatever it was. About 1mm..

Have a look at the photo's of bedding my Sako 75 in the "hunting tips" section.

Yes I did use a cut down gas fitting on the many 10/22's I bedded. But pipe was use on my .22lr CZ 455, 452 and Sako 75 , 308.

Good luck with that, IMO ur only putting a lot of work on yourself.

Did you even look at the tips in the hunting section? Plenty of photos there.

How do I find the hunting tips, with your sako 75??

Why aliexpress?????

You can get 6mm inside diameter tube at woodies and B&Q

Remember your compressing the tube between the action and the trigger guard. It will take a lot of pressure before you'll damage that tube.

You only need the same tube inside diameter as the action screws

No need, the Devcon will stick like sh!t to a blanket. Rough the tube up with sand paper if you like.

I just put the Ali tubes in, never roughed them up. Still there after 13 years and winning a UK championship with the Sako 75.

IMO your totally over thinking this bedding.

Clive is right you are overthinking, The second epoxy bedding will in most cases be better than your first. Just get going. We bed a few hundred stocks every year even so it is fairly labour intensive and results might have very small flaws, we are still learning.

My take. Brass Pillars are slightly better than alu just due to the heat expansion being closer to steel screws. Saying that we also use alu pillars in some cases. Hole inside the pillars we use 2mm larger than the action screw. After the bedding the action screw should be centre pillar and not touch any part of the stock in use. (centre the screw via tape etc in the pillars while bedding.) Outside diameter of our pillars are between 12 & 15mm. Carbon tube is another good pillar material. Our stocks have internal carbon pillars. Size of the pillars should be relativ to the hardness of the stock material.

The rifle action is the heart and soul of the rifle, this should be positioned and bedded perfectly in the stock first, then floor plate or mag system at a second stage. We prefer doing it this way.

Mix epoxy really well, after mixing remove most of the mix onto a second bowl or surface and mix again. You will see after curing there are soft spots in the first mixing bowl...

Fully cure before release. 24hr is better than 12hr. Slightly warmer helps curing.

Kiwi clear is mostly a good release agent however the are better professional release agents.

Any binding between the pillars and the screws would lead to inconsistent stress.
