Had this saw since 2002 and was cutting a large ingot (50 lbs) of mystery metal when it suddenly stopped working. Replaced toggle switch but still didn't work. Capacitor ok and motor checked out ok. Sitting there scratching my head when I noticed the power cord looked like some critter had been chewing on it. New plug and cord, plugged it in and darned if it didn't run. Cleaned it up with a wire brush and one of the maroon 3M pads. oiled it up. Last week was looking at a section of 40mm bofors gun barrel. Barrel had been demilled by torch cuts and had to be cut back to get to good metal. Had spare blades but teeth facing the wrong way. Took the replacement blade and turned it inside out, now teeth facing the right way. Barrel weighs north of 100lbs so used an old workmate to support it while being cut. 1'st cut took about 3 hours and plenty of oil. Second cut about 4 hours and also plenty of oil to lubricate the blade. Now have a section of barrel about 3' long. Npw have to see if I can somehow lift it onto my lathe and face both ends. My steady rest will only go 2 3/4" so just might call a machine shop in town. To face the ends off. And just maybey I'll actually make a cannon out of it. Lifting heavy stuff out of the picture for this old guy. And have to get my old pressure washer up and running. Frank

You need better bandsaw blades.

Threading for the breech plug might be a challenge best left to the machine shop too, will need high horsepower and carbide inserts to deal with that tough steel.

Ian, as far as better band saw blades your right. Was looking at the Lennox bi-metallic ones. And your absolutely right about the barrel being made out of some tough steel. Cannot weld on it as due to the nature of the steel, your supposed to do a pre heating, then welding and then a post heating. Got some pics from one of the members on the graybeard outdoors black powder forum. And he basically screwed the whole thing together. Probably end up with sort of a mini napoleon type when done. 44mm translates to slightly over 1.5 inches. Don't know how long it will take. Plenty of honey do's keep getting in the way. Frank

I had a couple of lengths of seamless one inch pipe that has a 2" OD.
we threaded it externally and used a solid end cap that got tack welded in place.
I worked up a load of clays which I won't publish anywhere even if asked because it shouldn't have worked, and would only serve to show that sometimes even stupid comes out on top.

anyway... LOL I made up a mold out of wood and poured some 1 and 1-1/2 ounce slugs that flew pretty straight only end over end after about 100yds. or so.
but you could spot your hits on the other side of the black canyon pretty easily when they made that splash against those black rocks.
