I know cutting down an old shotgun is near blasphemous, but, if one was to want to cut one down to 20", what would the finishing on the end of the barrel entail? Is there a spot that needs filling, between the barrels? Weld? JB Weld and sand? Just curious if I went that way... if I found an old shotgun with potential.

Here is a picture of what the end of one I am currently working on
It has been filed down to remove a ding in the end of one barrel.

Hope this helps.

To fill those voids you want copper wool, or a copper scrubber material. Stuff those holes with the material. Then get some annealed iron wire, and wrap a few times tightly around the barrels. Then take large head nails, or aluminum wedges and shove them between the wire and the bottom rib. This makes everything stay in place when you go to the next step.
Flux and solder the ends. The solder will flow into those voids and if you backed the copper in tight enough, it will eventually fill up. Leave a little solder bump where the voids were. When cool, file down the bumps, cut off the wires, polish and blue the barrels and you’re good to go.
PM me if you have any questions. I’ve done that repair several times.

So, you are telling me to take it to the gunsmith and quit thinking JB Weld. LOLOLOLOLOLOLOL.

Not necessarily, I cut one several years ago and stuffed the voids with scotch brite and overfilled the holes with JB Weld Epoxy then faced them flush. It was for a friend and as far as I know it's still in place....
 
There aren't rib supports on most double barrels, it sits flush with the barrels....

There are barrel spacers inside, and you’re not going to know where those are unless you one of the ribs.

Maybe JB Weld will hold, but why not solder it up correctly, if you’re going to the trouble of fixing it up. A propane torch and $20 of supplies is all you need.
 
I am certain the solder is a Better fix..howsomeeva, I've done around 30 of these with just JB Weld. Nary a problem...eva...

Not a fan of JB, but Quick Steel actually works really well in this application in my experience.
I have used it on several, and put hundreds of rounds through one little POS coach gun I shoot squirrels with at the house.
It will even darken up with cold blue due to its iron content.

It is probably a less ideal repair, but as Bubbu methods go, it is one of the better ones.
The stuff is really tough.
I made a tool handle out of the stuff for one of my scrapers like 8 years ago, and its still holding up.
