    Ah, Neuschwanstein, as copied by Walt Disney! Ludwig was unquestionably as cracked as the Liberty Bell, but probably not certifiably insane by modern standards. He built castles from his own fortune and irresponsible borrowing, not tax revenue. The...

    Sliding down fairly easily works well with medium-hard, heavy-bullet and heavily-charged .450 long-range rifles. That bullet might be a little longer, which I think is what controls upsetting (weight of lead compared with cross-section), but I am...

    I think there is a pretty good chance that a land diameter bullet would expand if it wasn't too hard. But a grooveless bullet would probably be better. Imagine the opposite, stretching a piece of rubber rod with grooves in it. Most of the stretching...

    Lawns are overrated. I like them best when they are long enough to see gusts of wind moving across them. I think it would give less than 120psi pressure until there was more resistance than a bullet would give. The usual mechanism was a hammer...

    File steel is some of the best for making knives, wood chisels etc. But the file-making process can leave cracks or some other form of weakness deeper than the teeth look to go. Belt-sanding that little bit deeper is a good idea. I have refreshed...

    It is puzzling to know why there are so many bad files around. 1095 steel isn't an expensive material for the bulk buyer - probably cheaper than the quick and easy forms of case-hardening - and about as good as anything for straight razors, which...

    I know how it is. I think the sphere reservoirs were often of copper, and I would guess that they were thick, made of two hemispheres with an interlocking flange, and silver soldered together. I believe they had a valve so that they could be...

    Yes, gasoline and various common solvents, or their vapour, are liable to come sneaking out looking for trouble, while powder stays where it is put. Gasoline combines with the oxygen from about nine times its weight in air too, so a pound of it...

    I think the difference with cans lies in the metal being intensely but momentarily heated by stress. Think of the heat generated by bending a pieceof wire to and fro till it breaks, being concentrated in a single millisecond with no chance to be...

    I don't claim to know much about electricity. I've never seen any, but it can be in there, invisible, waiting to leap out and zap you. I have, however, tried at great length to ignite individual powder grains, with the piezo-electric unit from a...

    Hammer lift is indeed progressive, but it shouldn't require replacement anything like every ten shots with any kind of nipple. Admittedly it will erode a lot faster than the bore, and yet black powder rifle bores wouldn't last anything like as well...

    That sight on the bayonet (solid I think, rather than dovetailed) was Austro-Hungarian. I don't remember which rifle in a time when Europe was so full of empires that couldn't afford to turn their backs on each other, that successive rearmaments...

    It should be very strong and resilient, but there is a quality that is hard to assess when you simply have a piece of it. There is a very good article on unconventional stock woods in "The NRA Gunsmithing Guide Updated". (It is an excellent...

    Yes, and the military Martini is unnecessarily wide, to accommodate its large cartridge, which is both difficult to load well with smokeless powders, and is very expensive in components and dies. I wish someone had made a Martini action a little...

    I'm sure the .222 Rimmed is one of the best for this rifle, but so is the German 5.6x50R, with cases available from RWS or Sellier and Bellot. The economics may be different outside Australia. In the UK Bertram .222 Rimmed costs 2.03 a time.

    There are a couple of sources for Cadet Martinis which might be of interest. I have bought several firearms over the years from this Australian auction house, whose online catalogue for their 29th April sale is now available. They have numerous...

    A while ago I mentioned http://www.peterdyson.co.uk/, who supplied my pair of Hollis hammers, ML16, with a 35mm.throw. But if they don't suit, I have found but not dealt with another firm, who look promising, and can make components (at a price...

    I made two firing-pin retaining collars for my Pieper 24ga breech-loader from a 7/32in. hex wrench, which I have a nut driver (like a screwdriver for nuts) to fit. I am surprise nobody seems to have got around to making hexagonal nipples.

    I'd be quite cautious with this. The salts of lead are far more dangerous than the metal, which old soldiers have been known to carry about inside them for many decades. The smaller an object is, the higher the ratio of the outside to the inside, so...

    It is only the nipple itself that it needs to pick. The angled path beyond the nipple is of much larger diameter, and what you need there is water, preferably hot enough to dry out the barrel before oiling. Back in the days when the muzzle-loader...

    That fits what General Hatcher says about the M1917 bore. He rejects the frequent suggestion that the M1917 had a loose bore because they simply continued using the .303 P14 dimensions. The standard bore, which he illustrates, was .300 and the...

    I've always been curious to know if anybody has seen an Eddystone P14 with an inspector's stamp for some part of John Charles Walsham Reith. John Reith, later Lord Reith of the BBC, was later the originator of the concept that broadcasting...
