Which Compound for building up?

aluminum and steel think Areonatical.

6061 is the low end of the scale in Aluminum
versus
2024. 7050, 7075 aluminum
The reason it gets a bad reputation is that it is soft and gummy compared to high-end alloys. If you try to machine it with the wrong speeds, feeds, or tools, it will instantly clog your cutters and leave a terrible surface fiinish.
One does what they have to, however look into 3m, Henkel Loctite Hysol Series, or Metalset A4.
Thank you.

Will look at these products. My gut thinks it is aluminum and I suspect these are not off the shelf (will need to be ordered) but that is precisely why I am asking (would hate to need the perfect product and it is days out).

This is fairly easy to get and it should have good adhesion but is it mechanically strong when cured or is it on the softer side?
 
Surely you know how to determine Make, Model and Caliber, and I'm guessing you know how to pass that info along...even a pic would go a long way in determining at least something.

Building up the surface of metal is not done often, at least in the manner you are inquiring about.
 
3M, Loctite, and several other companies make a two part epoxy putty that cures in a reasonable time, is super strong and in some cases can even be used under water.
Basically , it's like a roll of dough with an inner core that reacts when the amount needed is cut off the roll, ad the inner and outer layers kneaded together for several minutes.
It is strong enough to be machined afterwards.
Uses can be for cracks in pumps, sealing a leak in a boat, building of shafts, or in my case, being used as bedding coupnds or to build up gunstocks when fitting different actions to stocks that were not intended for them.
Here is an example of extreme modifications, a Mauser 98 action being fitted to a C.I.L. 950T stock ( Savage 110) using this epoxy putty that s widely used in heavy industry on pumps, etc.
The finished product was painted , of course, and turned out very well. This rifle is extremely accurate out to 1,000 meters.

Yes, I certainly do but my mechanically less inclined friend isn't so hot at it. Getting a picture would be like sending a rocket to the moon for them so I didn't even ask (reminds me of my father in law - not sure if he even owns a cell).

I know it is a 12 gauge (they seemed sure of that part) and it sounds like a semi. Beyond that I need to see it.

Hoping it is an easy fix and dreading it if it isn't.

Nice job. I have heard of "Bedding actions" before so guessing that looks like this too (I understand that in this instance you are using it to adapt a stock that isn't really for the action to be installed)?

How did you get the imprint so precise? Tape up the action and press it into wet not-yet-set epoxy?

I have used Steel Stick before for some obscure thing on a vehicle and it worked well so am somewhat familiar with this style of product.

All metal and screws are coated with a release agent before being set into the stock.
Shoe polish, paste wax, or grease are just a couple of examples of release agent, and there are commercially available ones as well.
This particular job was not a " one and done deal", several steps in the whole process were taken to ensure the job came out proper as far as fit and finish go.
