    Them Old Jokes

  2. At scale, using a median that expands and contracts with humidity and age, who has the tools to measure such small differences? Be difficult at full scale using the materials at hand and the measuring tools of the day. With computers it is handy to have precise mathematical data so that not accounting for minor details does not slowly accumulate and distort the whole. When Surveying, I did my Comps. to ten thousands, drawings were shown to hundredths and to be truthful on the ground be lucky to hold tenths, when monuments were set, time and natural movement moves things around, so discovering later measurements does not match the record is normal and seldom caused by mistake or sloppy work. If you have the time, tools and ability to take such things into account as the tapering of framing, great, just don't then forget that the outside of each frame is on a curve and not account for that also, most have little need for such detail to build dimensionally acceptable models at scale. The refinement of the data can get very detailed or it can be limited to actual useful data to accomplish the task at hand.
  3. Made one that used the whole firecracker for the propelling charge, Small threaded pipe, a couplier with a bored out grease zirk to run the fuse through. Hand held pistol like grip, worked fine except lighting that fuse and waiting for it, was impractical, after firing, most of the firecracker remained in the chamber and needed to be removed, accessed by unscrewing the zirk, scrape out and reload. Don't know where it ended up. Those things were always made so the projectial had little resistance, didn't take much to get it out the bore, even those that fired 22 ammo, I started the bullet from the case before loading. Never damaged or hurt anyone doing this stuff. I knew what I was playing with, had heard all the stories about kids being injured or killed, Loaded firearms were available to me all my life, so was aware of the energy involved. Loaded rifles were next to the doors to grab and go with, considered tools and were no mystery or conditioned fear of them, just part of the household.
  4. Should not be much of a problem with ring bolts. As a kid, I made at least 6 out of various stock and used black powder in them without excessive recoil except for 2 instances, one was a little over a 30 cal and loaded it with ample powder packed well, used wading around a 30 cal bullet and rammed it, it was a boat tail or I couldn't have started it, I stapled it to a 2 X 4 and buried the 2 X 4 into a hole in the dirt and packed the ground around it, the gun was up about a 1/4 inch, block stayed where I put it but was loose after the stapling failed and the barrel moved about half it's length rearward. The other was a 8" brass napoleon that I bought, shot ball bearings and BB's in it. Wondered what it would do if I filled the bore clear up with black powder, so I did, leaving room for wading. that time it flipped over on it's back, no harm done to the gun. Normal loading of any of my guns never produced any destructive recoil, Force, Mass and Distance tamed it well. This one only shot full rolls of caps and made ample noise and some smoke. Was 13 when I put i together. Pulled the combine in wheat harvest the same year, that is Dad on the machine, plenty of work for a kid on a ranch in the 50s.
  5. Chock, the kind you can buy for a Blackboard are good fillers for files. With a clean file just rub the chock over the teeth, knock the loose chock off and it will help prevent plugging. I use in on files and rasps, transferring chock to your work should not be a problem, wiping a rag over the teeth before use should prevent that. Use diamond hones for edges, never had a diamond file in my hand.

    Cannon Maintenance

    When fast torpedo boats and aircraft came into their own, going to Action Stations or General Quarters in a war Zone for Sunrise and Sunset became the norm, because attacking from out of the sun just coming over the horizon or dipping into it was advantageous, with the Radars and Gun Control Systems of today, not so much. Although ready service ammunition was at the gun or very close to it, it was not normal to load it, in the days of sail there was plenty of time for that and as Breach Loaders became the norm, it did not take long to load the guns. Muzzle loaders had, as part of their equipment a large screw device with a pointed end to the screw all mounted to a ramrod. It was used to work the projectial loose so it could be withdrawn or rolled out on it own and the powder bag also was hooked and withdrawn with that tool. Fixed ammo for a breach loader all is contained and held together by the cartridge case that is manufactured with a way to control head space and to extract the cartridge with or without it being fired. With rifled guns the lands and groves do not start abruptly, there is a forcing cone built into the barrel that allows for transition for the rotating band or brass bullet jacket to fit itself. On Semi Fixed or Bag type guns, all that is there but the rammer does not ram the projectial far enough into the forcing cone that it can't be backed out with a ramrod through the muzzle if it does not follow the cartridge out with a raised muzzle for Semi Fixed Ammo, Bag Guns require the ramrod after the powder bags have been withdrawn. and are a pain in the butt unloading in any manner but through the muzzle, in other words, shooting the dam thing. Never had to unload a Bag gun, we did not load them unless we intended to shoot and the loading was done on command, not an automatic part of manning the guns. Have unloaded many times misfires from 3"50s and a few 40MM Bofers, but always attempted to get them to fire by rigging a firing circuit or in the case of the 40 MM Bofers re-cocking the firing pin. Re-cocking the firing pin on a Bofers is not taught, because it involves unlocking the breach, but by marking the side of the housing at the point the cocking lever can be moved to, too re-cock without moving the breach can safely be done. The first thing I did when going aboard a ship with Bofers was to determine that spot, and mark it with red paint.

  8. Congratulations on a job well done. Need to copy this log onto a couple of Thumb Drives, one to go with the model and one to keep. jud

    MSW plastic invasion?

    Problem with exclusive sites, they grow more exclusive every day, appears that the lesson that an exclusive site usually starts with a bang and dies as a lake with the dam breached has been in mind. This site has avoided that so far but it is always in danger of becoming an elate group. Today there is enough variety to discourage that from happening. Exceptional leadership and wisdom has been shown in this site's development, we are lucky bunch to have such a site. Embracing all model building techniques, materials and all levels of modelers will assure it's longevity. Jud

    Coiling Lines Option

    If and when that glue breaks down, those coils should be well trained and stay as they are.
  11. Don't think those numbers and arrows are intended to be used as Bench Marks. 10.6 is a very in-precise measurement, a tenth of a foot is approximately 1.2 inches if Imperial, reduced to decimal units, then there is the decision where to round off that last digit, several different rules and standards were and are used today. Elevations are typically given as hundredths and sometime thousands of a foot depending on the intended use, obtaining such precision is and was not that difficult, which in my mind, makes those numbers doubtful that they represent any Surveying standards for marking Bench Marks. A tenth of a foot would represent a lower standard of measurement than was needed to construct the Battery position and its buildings in the first place. It was noted above that the physical vertical positions would be closer to 10.6 meters above Sea level, rather than 10.6 feet, a tenth of a meter would be 100 MM, converted to feet, 3.94 inches or .328 feet. Suspect the experienced Artillery Gentleman had limited experience with fixed gun positions such as a coastal battery and was making a guess, perhaps tainted by the way the question was asked. So, the numbers not matching the physical elevation and the way the numbers were written, makes me question there use as Bench Marks, I will continue to wonder what they are, what they are intended to represent and how they were used. Hope someone has something in a reference library or knows offhand that would reveal what they are.
  12. Was a discussion on this subject several years ago, venting the case using cotton waist as a dust filter was one of the solutions.
  13. Survey marks would normally not be vertical arrows. Indicators of magnetic North are temporary, magnetic North moves constantly and mass will pull a needle, so I doubt that is what they represent. Suspect it is a reference mark related to the pivot point of the gun, and used in orientating a indicator ring around the pivot point of each gun. Probably originally marked from astronomic observations taken from the pivot point of each gun, the numbers were probably file index numbers, close positions could use the same data but would need adjusting as distance increased between gun positions. Using rings indexed to the marks, fire could be concentrated to one close point by adjusting the paralex when using the marked rings, ' adjustments required from the dispersal points of the guns', when laying the gun using the preset rings, one gun was probably fired to obtain direction and range, all guns in the battery could then be brought onto the target using the indexing rings that had been orientated to the index marks. Sounds like a bunch of BS to me, but having been a Gunner and a Land Surveyor in my working years, is my non-researched best guess.
  14. Built that model in 72. Only rigged the standing rigging and my painting was with a brush. Would have been a big help and had a nicer outcome if this site had existed, my experience with modeling was with the Ships, automobiles and airplanes available in the late 50's up to about 66, so the results were rough, but she looked good up on the shelf, dust was a problem and after some top-hamper was damaged, I gave it away. Will be watching, makes an attractive model and worth the effort to build.
  15. Bruce, have one similar hanging in it's box on the peg board, $16.95 in 1994 on the tag glued to the box., 'C2E Bavarian' 6 1/2".
