Curious about what the fellow thought when he seen the rifle.
Drill + tap failure. Backwoods Outdoors Corbeil Ontario.

My reply wasn't to the OP, just comparing methods of drill&tap blind holes
It's a job I really don't like doing. It's not bad on larger jobs, like machinery bases etc but it's really easy to make holes in a barrel to deep and if you've got one wrong size drill bit in a drawer full of bits, guess which one you will pick up first. Number drills are the worst.
Before I became reasonably comfortable with drilling and tapping blind holes I took a length of cold rolled off the wall rack to practice on. That was years ago and an old hand at such things, in our shop showed me the system I wrote about. It's not infallible, but it works for me.
Nice!

If you haven't seen this before, check it out.
I will try this on a scrap barrel in the bin and see how well it holds
I will of course rough up the surfaces first. Might only work with plastic.
Hoping it will give such a super strong bond between two metals, such as aluminum/steel or brass/steel or even steel to steel.

That's super interesting. Gonna have to try that! I dunno on what yet mind you...
Turns out you can do similar things with Super Glue and cigarette ash, cotton balls etc.
It makes sense. I'm going to play with a few things just for curiosity's sake. Should be interesting at the very least.
The baking soda just acts as an accelerant for the super glue, it doesn't increase the strength of the bond. If you just waited for the glue to dry and stacked up layers, it would have similar strength. Adding extra junk to the mix also won't increase the strength of the bond, super glue is still just super glue.
That video is a very typical clickbait garbage video you see everywhere.

Thanks for this. much appreciated.
I'm going to try the iron filings one though, just because.
I don't disagree with your opinion of the video, but the Baking soda does not act as an accelerant, it just provides a lot of closely spaced surface area for the super glue to wick through and bond together, in places where the fit-up is poor.
Baking soda was cheaper and more easily available than say, glass micro-balloons, back when I was flying balsa RC Gliders and the like.
Clean dry sand works pretty well too, just harder to smooth off afterwards! LOL!
But hey, lots of guys think JB Weld is actually welding, and not just chitty epoxy with metal powder in it, too!

It is not welding, but I will, and have, put JB up against any other cold cure epoxy that you care to name.
Devcon, Marinetex, Acraglas, etc.

There’s no way you watched the video and really came to that conclusion. Make me a wrench mould with just glue then if it truly does nothing!
No. I refused to bring the rifle back to him.
Horsefeathers. Sh!t happens even in the best establishments.
I've seen some very nasty mistakes from some very good smiths, with a lot of skill. I've never had one try to duck out on the fubar though.
I know a smith in Sask building faux No4 T rifles that look beautiful on the outside but I wouldn't order one from him. They aren't meant to be shot, just for display. That doesn't mean they aren't safe to shoot but many of the parts are refinished scrap bits.
Most smiths will inform their customers of such a screw up and either go good for it, fix it etc. Jimbobob08 ran into some misfortune that would likely be unpredictable.
Smiths are in short supply right now across Canada. Often, depending on where you live, give a smith your firearm to repair and it will be months or even up to a year before it's repaired. If the smith is a parts replacer and hasn't got the skillset, equipment or time to make the part, it could even take longer, especially if they're waiting for an obsolete part.
^^ this is true. I'm not a gun Smith by any stretch of the word but I've done a few things for a few people.
One time I was send 3 Lee Enfield barrels to have their Knox form turned into a barrel nut/thread adaptor ( similar to the cooey carcano rifles Knox) but the tail stock was off a few mm from someone else cutting a taper
so I tapped these barrel nuts using the tail stock. Guess what, the threads were way off on one side. The only way I saw to fix it was to tell the guy what happened and then proceed to make him 4 new barrel nuts out of 1045. ( One of those barrel nuts happen to be used in my "building a classic sporting rifle" thread)
