Jaager got a reaction from Mike Y in Inert gas in a completed model's display case for preservation?
I have thought about the same ideas.
For the gas to remain, the container would have to be
air tight. The walls are transparent, so light can enter.
Being totally sealed, there is a possibility of an extreme
greenhouse effect and the container becoming oven-like.
There is a problem with this - even in a not totally air tight situation.
Joel has it correct - vent holes for circulation for both temp and
removal of outgassed compounds. PVA wood glue would probably
release acetic acid.
My thinking is vent openings at the top ( for temp ) and probably
also bottom for circulation. The trick would be to keep dust out.
Too dry - the wood may check and split over time.
.The museum standards for ship models are probably intended to
preserve a model for as long as is practical - by using materials that
last to begin with.

Jaager got a reaction from flying_dutchman2 in Making Rope
The linen supplier twists up the fibers into yarn.
This is sold as LEA - which is essentially an obsolete measurement - it has been replaced -
but I have not mentally absorbed it. Since I have obtained about as much and as wide a
variety of linen yarn as is obtainable now, I don't need to deal with the change.
And yes, with LEA - the larger the number - the smaller the yarn.
From our perspective the hope would be that 70.2 LEA yarn would be 2 lines with a final size of 70,
but alas - what it means is
Two 70 LEA yarns twisted together and sold as a loosely twisted thread..
If unraveled it would be two 70 LEA yarns - not two 140 LEA - which would be nice for us
except - twisting up the 62 LEA is difficult - it breaks easily - so that may be the practical limit.
I finally got why the old guys favored linen - the linen wrapping on Egyptian mummies is still largely intact.
It does not readily oxidize.

Jaager got a reaction from flying_dutchman2 in Making Rope
This I did using a Byrnes rope walk. I will have to play with the setup
to get the warps more acute but that should not affect these data significantly.
100/3 = 100 LEA linen yarn spun up using 3 yarns.
The diameter was measured using a lacquered dowel and counting the
closely packed rotations in an inch.

Jaager got a reaction from thibaultron in Cyanoacrylate (CA) Glue for Rigging
I use a lot of lacquer to coat and stiffen my patterns, but I would not enjoy
using it inside. The solvent gemisch seems kind of unhealthy.
For PVA, I think bookbinders neutral pH - woodworkers PVA is acidic.
No data but isn't CA weak in resisting shear forces? I think shear is a major
factor with rigging.

Jaager got a reaction from mtaylor in Dremel 200 - Any good for a basic ship build?
Your Dremel will get you there. There are external speed controls (solid state) if you find it
burns your work. To be prudent, you may wish to avoid buying another powered rotary tool
until you are far enough in that you know what you need.
Pin vise = hand power- - there is a variety of them. A basic General - 4 size collets - metal
swivel is a good first choice.

Jaager got a reaction from thibaultron in Cannon Breech Rope Length
Mike,
I also see the ambiguity with the breach rope length, but
when thinking about it - do the experiment with the scale
model - if the recoil distance is 24 feet? Is it so far as to
smash gun crews on the opposite side or roll the gun over
a hatch opening ( as much as those guns weighed, there is
a chance that only the sea floor would stop it.)
The tackle - left taut - it would slightly restrain and spread out
the recoil stress. It would also stress the tackle gear and probably
shorten its working life. In the ciaos of battle - I wonder if fingers
could be lost if the gun were fired before crewman loosening the gear
finished.
-
Jaager got a reaction from thibaultron in Cannon Breech Rope Length
I would think that the goal would be to have the recoil be enough for
the gun to be sponged, cleared, loaded, and rammed while inside the
ship. Plus, anyone outside the ship would make a tempting target for
the Marines of the opposition. But, since the gun had to bet returned
to brace the trucks against the spirketting, it would be inefficient to
have the hauling distance be any more than was necessary. Keeping
the work of hauling at a minimum and having the load and fire interval
as short as possible - both important?
It seems likely that there were tables giving breach rope length for
each caliber or barrel length of gun.
