YouTuber “This Stuff I Do” was inspired by a project which made a screwdriver from rebar and decided to make .22 barrel from rebar.
The barrel is made from one inch rebar about 18 inches long from a scrap yard. Here is his description of the work:
First I center-drilled the end and went about 3″ in with a standard-length 5/16 drill bit. Then I deep-drilled it about 10″ using a Dewalt branded installer bit from the local home center. I expected this bit to burn out pretty quickly through so much solid steel but it actually performed very well and is still sharp. Good for Dewalt for choosing a high quality OEM. After the bar was drilled through, I ground off a few of the ribs and milled a nice flat. A chunk of steel was then measured and cut to fit into the hinge of the gun. These two parts were TIG welded together and the barrel liner was chambered and epoxied in place.
He finishes the project in two other videos:
