  1. Jaager, glad to see someone expanded on my chainsaw post, modeling kits certainly have made many power tools overkill. Some start scratch building at the cured log, end product may resemble a kit, but it requires much more effort. Some mighty fine models were produced long ago without power tools as you know. Your list of methods clarifies my statement about goals much better than I did, that is the primary starting point for acquiring and it sets the limits for useful power tools.
  2. A good chainsaw would be a big help in harvesting your raw material, I would ask someone in your area what they use for that job. Opened up a big subject, without a hint about what your goals are, sometimes the tools you are using are the best choice, supplemented by a good rotary tool with a selection of chucks to broaden the usefulness of the thing might be a good start but not much good for cutting out Frames. Adding various fixtures that the rotary can be clamped into is often a step taken to refine cuts. You need to refine your goals to obtain useful information or you will end up with lots of chainsaws and a few axes hanging on your wall. Good luck. Use the right tool for the job.
  3. Parrott's and other rifles were the tools of our Civil War after stronger iron was available and improved casting methods were developed, Used it mainly because of the impossibility or intent of these ships intentionally coming under fire from shore guns or even larger guns afloat in ships. These ships were never intended to be the targets of shore batteries or ship in a slugfest, expect they operated along rivers and within sheltered waters against small craft filled with men armed with cutting weapons, perhaps some muskets, but mainly equipped for boarding. If you notice the design, the pivoting part of the mounts were just dropped into place. A half dozen pivots with guns could just be dropped into the solid fixture, another dozen without the guns for a slower but still quick change. These guns I expect were 1 pound guns, don't think a 3 pounder would allow repeat firing and this vessel was set up for sustained intense fire and that would require more men than could comfortably be carried as Ships Company for extended periods, manpower was probably supplemented from support vessels, they manned the guns while the crew worked the ship or oars.
  4. Trunnions are where they are to act directly into the mass to their rear when firing, Looks like the they are held in place from the front by that block secured in place by bolts. Well designed mounting intended for a specific, but repeatable use.
  5. Swivel guns also had no provisions for recoil movement and I am sure that if an oversized propelling charge, coupled with to much shot were used, damage would be done to these guns as well as Swivel Guns. Because of that, I suspect that complete cartridges containing powder and shot were made up in advance to avoid inadvertent overcharging also with the benefit of faster reloads. Recoil energy is always there, it can be controlled in several ways using mass, time and distance. Mass alone can be used and any residual forces that pass through to the ships hull would cause it to do its thing and flex. Ships hulls are flexible things or they would be quickly destroyed by all the reversing forces acting on them, so residuals remaining from firing these small guns would not cause any excessive stress to the hull. From the drawings, it would appear that the flexibility of the hull was used to do just that. We know that Swivel Guns did their jobs in spite of no recoil system other than the flexibility of the ships hull and the timber it was mounted to, we also know that the people using this equipment had some first hand experience and knew what the upper limits of loading would be to avoid immediate destruction of the mounting. Our Saluting Battery aboard the Helena CA 75 was a 40MM Bofors Breech Housing and all the Breechblock operating system, using a modified sear, originally designed to fire when the breech was latched on closed, (ram a round, the rim on that round released the extractors setting the block free to close and fire the round), needed modification so the firing pin was released using a lanyard so the timing could be controlled with a closed breech. A short section of barrel was screwed and locked into the housing and the whole thing bolted solid, with a bit of elevation to a mount with 4 legs bolted to a ring welded to the deck, all rigid except for the hull it was mounted to, a lot of energy was stored into those 40MM full sized blanks. This gun arrangement looks like a legitimate and useful rig in the hands of trained crews and leaders, will there be failures, yep, to long in service, defects and overcharges would be expected, but even a 10 percent failure would not put this vessel out of the fight it was intended to be in. Now some clown with his 30 pound Parrott Rifle would quickly would quickly ruin their day. .
  6. Like the swivel and elevation system. Trunnions are set so the gun could be aimed down very close to the ships hull and if aimed forward or aft could get closer, would expect some boarding hazards to be part of the rigged for action arrangement, also would expect 3 guns to be assigned one target and move on together to the next, at least that is how I would start the action were I in charge of the battery. Photo; M 79, M 16 and concussion grenades were our anti boarding tools, swimmers did get through once and left 3 mines, comand detonated, one of the 3 had a low order detonation, made us hard to approach unannounced. What do you tell your gun crew, when you and they all heard the SEAL holler up from the water below you, say there was a mine under us and he was going to attempt to disable, then recover it, while we kept the gun manned?
  7. I also questioned the intent was for gunnery training, Mounts, and guns do not appear to represent the norm required for worthwhile training. Suspect it was intended to be used to clear hoards of lightly armed natives, massed on a landing area or afloat in small craft, could be for river use or in a protected Bay against small craft, swimmers or troops on the shore. Expect there were more than one shallow water vesel armed this way for special short term use, crewed by assigned crew, filled out to work the guns using drafts of gunners from acompaining support vessels. The lower structure was probably reinforced with iron bars, bands and fitted with an iron swivel socket for the training pivot of the upper carriage. Pre-manufactured ammo designed for this use would avoid over charging. a cylinder of silk or linen, 'both requiring a wet swab', with a measured powder charge behind a container of balls would be be fast and easy to load by a 2 man crew. The mass of the gun would absorb much of the recoil energy, swivel guns did not seem to be a problem, no reason a heavier gun, properly loaded, would cause problems to a mounting fixture designed for that job. Suspect this represents a solution to a on site Commanders need to clear the way or protecting his main force from masses of enemy engulfing them.
  8. The restoration looks as if it was intended to repair, not replicate. Like it, what is new is not hidden, provides a timeline of shorts. The quality of the repair work is profesional. Suspect it was done as requested. JerseyCity Frankie, Does your friend have some data or know where to look for more history of this model and what it represents?
  9. Looks like a special mission setup, the rest of the model would make one assume that the modeler was knowledgeable about ships and their weapons. Two men per gun, heavy barrel with elevation and swiveling abilities? Swivel Guns come to mind. A ship setup to go close to many would need such a setup firing canister. Light charges with quick reloading, wide range of aiming possibilities with mass heavy enough to absorb the recoil when small propelling charges behind a cloth bag of musket balls was used. Suspect she was intended to go close to shore to break up and push back a mass of people so small boats could land and their troops would have enough time to get into formation, or a trip up river occupied by many with canoes that need emptying so other ships can make the passage without being overwhelmed. This one's a mystery so far, don't think it represents a brain fart, suspect it represents a solution devised on site to overcome mass's of lightly armed people, probably nativies with little technology. River Patrol;
  10. Admire your work, hope you continue posting. I do have a ship in mind that has a long history and still serves in the South China Sea. A bit of self interest because I was a Gunners Mate aboard her when she was the Harnett County LST 821, TF 116, TU 76.8.3, one of four LST's in that role and would puff up like a balloon if you found her worthy of a drawing. Brown Water Navy. http://defensestatecraft.blogspot.com/2014/04/treasure-of-sierra-madre-wwii-lst-in.html
  11. Suspect you are following the right scent, would expect a gang of fairleads and blocks to lead the mooring line to the Capstan. Ever lead the forward line through a chock, around a bit and on to the Capstan? When the ship was in place then using a stopper to hold the tension while taking the turns on the bitts so you could double up without losing the tension, bundling with small line and putting the Rat Guards on. Those openings look to be in the proper place for mooring alongside a pier.
  12. Great progress. You mentioned netting with a photo above, suspect the netting of today is for child and pet safety, there for insurance purposes. The railings and Bullworks should suffice for a working cargo ship and did not exist in her working years. Have admired your progress through one wreck after another with the model and your life, it has made you into a fine modeler with unique skills, patience and empathy for others, proud of you.
  13. I have read somewhere in this Forum that the messenger loop used around the Capstan came about with the increase in size of the Anchor Cable to where it would have been damaged by passing it around the Drum several times. The loop was tight enough to guide itself and pass around a fixture at its forward turnback, under tension only between the Capstan and the most forward tie to the cable. I suspect it was all taken down and stored below unless needed, that being the reason it is seldom seen in drawings and paintings, models followed suit.
  14. Have tormented myself that way without the mesh stick, thanks. The lack of that tool defeated me on every attempt at net making.
  15. HM Bark Endeavour by Dashi - Caldercraft - scale 1:64 - 1768-71 - bashed kit. This is a build log you must study, much thought, research and why asked, with solutions, sometimes outside the accepted, I am impressed with the work but more so with the Gray Matter used and reasons given for deviating from the norm. Some testing done in order to determine if solutions were practical enough to have worked in real life, chock full of questions, research and testing. One item I believe this work has established was the crossover built over the tiller, why? Cook needed a place to set up his Plane Table and Alidade, this was addressed. Others just blindly built a crossover where a Seaman or Officer would normally, just step over the tiller, mucking up the rear deck area. This Log is well worth your time to study closely. Finding a kit true to the original I suspect is imposable, some closer than others, Dashi bashed her kit, rewards in following her guidance, research and adding to it by your research.
