I think Lieste has found some authority for the "screening" explanation. Good research work!

Concealment of the exact location of the embrasure. Also hides the the movement of the crew and the running out of the gun.

jud got a reaction from mtaylor in Swivel guns
I suspect there was no hard and fast rule on mounting height of swivel guns that was not related to location and intended target. If mounted aloft and sighting down the gun to a neighboring ship, close enough to justify shooting, knee high would be about right, If mounted on the bulwarks and the intended target was the upper works of you enemy then head high would work, allowing the gunner to squat to aim. If intended for a horizontal slugfest, then mount a Quaker and ambush your foe while their attention is on the dummy. Swivel guns are intended to be pointed and aimed quickly so mounting height is considered when placing them. An adjustable mounting for height would be nice, the 20MM Oerlikon was basically a Swivel gun and the mount permited the height of the gun trunnions to be varied easily and rapidly for any sight angle, to suit the convenience of the gunner. This is done by the column raising handwheel mounted on the pedestal head.

jud got a reaction from Bob Cleek in Mini spot welder to weld railing
Put the arc welder away and use a gas torch to weld with if you must weld, be better to braze the joints. From the net; A brazed joint is made in a completely different manner from a welded joint. The first big difference is in temperature – brazing does not melt the base metals.

Wood clad in sheet metal would encourage rot, so I suspect it was not the practice. Cast Iron or bronze gratings would withstand the heat, steam and greasy smoke they would be subject to and also be reasonably easy to remove for cleaning.

jud reacted to mtaylor in Rattlesnake Quarterdeck Bulkhead Design
Many times, those bulkheads under the quarterdeck/poop and under forecastle were removable. Maybe even most of the time. Removing them to below deck would do several things.... it allowed a bit better ventilation to get the smoke from the guns to clear out, it also removed extras sources of splinters (glass and wood) and lastly, it gave better access for the gunners to work and also hear commands.

jud got a reaction from mtaylor in Rattlesnake Quarterdeck Bulkhead Design
Rattlesnake was built as a Privateer, 'civilian warship', ornate carvings are not fragile and were relative cheap at the time, can become splinter hazards if hit with a round cannon shot. There was no safety glass in those days and broken glass cuts today, just as it did then, we go to great effort to prevent it from flying around in large chunks when broken. Small ships with large crews needed to fight and provide for Prize Crews, could not stay at sea long before provisions were used up, those provisions would have filled every available space, leaving no free space to strike glass below or carry safety covers for it, heck the crews probably slept in every corner around the weather decks and in every cranny below. I don't believe glass was used at all in these ships, except for perhaps to pass light into a magazine, because of its danger and the cost in a vessel built strictly for going into harms way for profit. Often showing a light at night was dangerous for small vessels. We live in a well lit word, in Rattlesnake's day, they had learned to do well with little artificial light or windows.

jud reacted to iMustBeCrazy in Rattlesnake Quarterdeck Bulkhead Design
I don't think anybody is going to prove you wrong whichever way you do it.
Two points to consider however:
Glass in America at the time wasn't cheap.
Glass in doors would be far more likely to break.
That said, perhaps small panes in heavy frames would be the way to go.

jud reacted to druxey in dead eye twist
Further to Phil's (Dr.PR) post: The direction the laniard is reeved through the deadeyes can either increase or reduce the tendency to twist. This is important if you are modeling a ship in the pre-sheerpole era!

jud got a reaction from Mexspur in Thinking things throu, carronade carriages
Little more than the weight of the rear of the gun on the screw, before, during and after firing. The initial beginning load on the screw will vary a bit at different elevations of the gun tube and roll of the ship. Don't forget that a recoil system is intended to spread the force of recoil over time and distance, the carrage with it's slide is a recoil system and the line running through the block and tackels is another part of that system. The breaching is a safety device to keep the gun in the area it is intended to be and seldom even has the slack taken out of it by the forces of recoil. The block and tackle at the side of a gun are used as dampers on the recoil as well as used to pull the gun back into battery and also used as an aiming device. The screw only controls the elevation of the vertical part of aiming the gun and supports the static weight of the gun. That screw being ridigly secured to the breach end of the gun by a threaded hole is free to move with the threads, the bottom end, unless provisions are made, just drags back and forth on whatever it is resting on when the gun elevation is changed. Gun tube rotates and everything secured to it moves with it around the trunnion. This is a good discussion about a small but important part of those historical guns.

jud got a reaction from mtaylor in Ratline distance
Not a ratline, but spacing is wrong, it stayed wrong, never wore it out because of a collision at sea 19 July 1960. Me, 1960 when still on Deck Force leaving the Whale Boat after a run. I, being a newbie was the Bow Hook.
