It's cast from silicon bronze (6% Si, the rest ...

copper and trace elements) which the art class uses because its fluidity allows it to flow into fine detail typical of art castings. It is a mixture of virgin and recast metal, probably more than 50% virgin. It is very abrasive to machine; eats up HSS faster than you can say "Oh sh*t!" C-2 carbide w...

finished of the four barrels I have cast. This one has virtually all of the external machining finished and is partially bored. The material in front of the muzzle ring is for the steady rest and will not be there when the tube is completely finished. http://lassengunsmithing.com/images/mtnhwzr2.jpg...

I can't pass up a question like that even though..

this is probably a little bigger than you're interested in. :-) For scale, the target is an SR-1 (6.33" dia. black) and the projectile diameter is 1.18" and weighs about 10 oz.

"accelerated rust blue" but if you don't have to immerse the barrel in the boiling solution for an extended period of time, then tightly fitted hardwood plugs will probably be OK. But if the process requires soaking in boiling solution for multiple minutes, the pressure built up inside the barrel is...

wrap a chain around the shrub and wrap the other end around a frame member of your 4x4 and idle away. Works great if the ground is damp.

the shop but I'll bet the well water is warm enough to extract some "free" heat from. Try running your "air conditioner" for a day or two and see what the result is.

You could always resort to a waste oil burning heater. Used motor oil should be easy to find.

With the lathe turned OFF, engage the half nut ...

and crank the carriage back and forth; look to see if the lead screw is moving with the carriage and how much it moves. I expect the lead screw will not be moving much, which implies most of the wear is in the half nut/lead screw relationship. Usually the half nut wears a lot faster than the lead sc...
