Re: First time cutting flutes in a barrel

No, I clamped from underneath and cut on the top with the spindle vertical. I didn't see any issue with the center of the end mill cutting. I have heard to tilt the spindle so the center isn't cutting but that was after I had done the barrel. That would give a little different exit shape but no matt...

Re: Does lapping in the locking lugs on bolt increase head s

While the standard headspace for belted cases is measured between the breech face and the front of the belt, most accuracy wonks will eventually headspace off the shoulder as with normal bottleneck cases. Part of the problem is the belt is pretty narrow and the brass doesn't always fit it well. Anot...

Re: cannon

My experience with stainless for black powder cannon barrels has been good and they seem to clean up much faster and more thoroughly than steels like 1018.

Re: Does lapping in the locking lugs on bolt increase head s

Yes, you will get an increase in headspace because you are removing metal from the locking surfaces. How much an increase depends on how good the contact is when you start. The first thing to establish is how well the lugs seat before you start. If there is a lot of contact, then you may decide not ...

Re: cannon

If you can keep the temperature of the barrel below 500°F, you are probably OK, but I am more or less guessing about that. I think even 500°F will start the lessening of hardness and therefore, strength. Although you may have been successful with silver soldered trunnions, it may be because the pres...

Re: cannon

The downside of a fabricated brass barrel is attaching the trunnions. You don't want to heat it excessively or you will anneal the brass to its softest state which is not desirable. While I would have no concern silver soldering trunnions to a steel barrel, I would not do so with a brass one.

Re: Pronunciation

I should've bought half-a-dozen when they were $12.95.

Yeah, but $12.95 was a lot harder to come by in those days. And ammo would be a problem.

Re: Pronunciation

I think the correct spelling is Webley and I have always pronounced it the obvious way, webly. However, that is no guarantee it is what the original designer said.

Re: First time cutting flutes in a barrel

I used a carbide ball nose end mill so it would stay sharp throughout the process. My barrel was cylindrical so it wasn't too hard to set up. As I recall, it was held in an indexer and footstock and I clamped it to an angle plate in the middle for more uniform support.

Re: cannon

Shot should not be patched for use with a cannon. Nominal windage is bore is 2.5% larger than the shot. Measure a number of shot and use the largest since sticking a shot when loading is to be avoided. Cannon should not be loaded with loads for muzzle loading rifles or pistols of the same caliber; t...

Re: making a mount to attach on a pic rail

I use a double 45 to make the ones I have made but the cutters are usually too thick and I end up with clearance above the rail. It hasn't caused any problems but I don't get a close fit there. I suppose I could grind off the top of the cutter for more clearance.
