Thank you to all for the compliments and likes, it makes the work go a lot easier.
I went down a few rabbit holes trying to determine what the canister in question is, in searching I came across the following from Gunnery Catechism by J.D. Brandt published 1864..........PG 97 regarding riffled ammunition, "The base of every rifle projectile shall be greased before putting it into the gun".

All the guns on the Tennessee's main deck are rifled, I think this is a grease canister for projectiles and carriage. One would think that grease would be made available at every firing station, not in a bucket to be stepped in or fouled with sand but something like the canister in question with a narrow neck with the opening being above deck so as not to be contaminated.
This is my best guess and unless someone has a better one, I moving on.
This is "what is it" prototype at .20 wide and .45 high. There needs to be a little tweaking before going into a nine piece run.
Thank you again to each of you.

Hi Keith, it is possible that the rounds were passed up to the upper deck through a hatch/trunk/hoist from the shell room.  It would make sense then that only a single greasing station would be required as the crew would grab the round from the hoist, grease it and pass it to the required gun station.  Could the device be a combined hoist/greasing station?  Not trying to complicate the matter, just a suggestion.

Nice metal work Pat, I wish I had the skill sets to do likewise.

Brilliant! simply Brilliant!

Even more amazing!

I like that 'divide et impera'-method for the chain sprocket. When I was doing it for my current project, I messed around with a tiny spherical burr. Sometimes one just needs to think of a strategy at the right moment ...
 
Sherline doesn't do a compound vice. They only do a tilting table, on which their vice can be mounted.
 
As I don't have enough space under the head of my mill for a commercial compound vice, I made a simple tilting fixture for a 25 mm toolmaker's vice from some 25 mm x 25 mm aluminium bar. The crucial dimensions were milled in situ:
 


 
The angle is set using angle-templates between the surface of the vice and the spindle nose. I have a set in 5° steps. For other angles, one will need to mess around with a protractor.

Kieth,
 
Your metal work is almost supernatural kudos. I read somewhere about human osmosis. From what I read we need to meet do a fist bump and your skills will be transferred to me by human altering osmosis.
 
Bad thing is my ineptitude in certain aspects of modeling may be transferred to you.
 
Good thought bad idea.

Lovely work, Pat. I'm very hamfisted with soldering. Your work leaves me awestruck.

Some small updates as I have been somewhat delayed/distracted rebuilding a new computer.
 
WRT to the Contract calling for 'Cranes" (see post #513), I decided to go with a gooseneck davit, as nothing more complicate would have been need.   The photo shows one in situ with a temporary ash bucket.  I will replace that with a metal one  (wood or canvas I think will have been burnt when removing ash with possible hot embers still in it).
 

 
I have also made a start on the bowsprit.  I have shaped it (and the combined jibbooms - but the latter broke ) and I now am in the process of adding fittings (heel stop etc) which is not shown, and starting on the ironwork.  The photos show the Bowsprit Cap in two stages of its manufacture.  I used a jig (two dowels appropriately spaced in some scrap wood to hold the brass tube while I soldered them together and added the sides, then filed them.   The first photo sows the assembly after it has been parted off with a dental cutting (separation) disk  (much stronger and better than the standard Dremel disks)). 
 
I have soldered on the base lug with two hole for the Bobstay (after hole) and for the martingale (forward hoe), and two of the side lugs for guys etc.  Two more lugs to be added, plus two 'horns' at the top for the man ropes.  The side lugs are copper wire which I am filing flat after soldering to give the impression of flat forged lugs.  Very fiddly at this scale but getting there without blowing the lot apart as I solder the lugs into drilled holes (fingers crossed  and touching wood as I say that).  I still need to work out how I will add the Jackstaff bracket; then a LOT of cleaning up before blackening.
 
The form and structure of the Cap is based on drawings by Underhill.

Good detective work.  The beauty of it is... who's going to argue with you about it?

As good a 'solution' as any could determine, and it makes some sense Keith.

Thank you Eberhard, Pat, Keith, Michael, Gary and Richard. 
Strange times in which we live - today I had a conversation with a neighbour when we were both on opposite sides of the road, people pass in the park while maintaining a significant distance. Apparently dog food is in short supply - even the dogs seem to have caught the hoarding bug.
 
Anyway - on with the winches:-
The chain sprockets were made in two halves. The outer diameter was calculated based on measurements of the chain. Six scallops were cut out on the mill using the hex collet block. 

The halves were then parted off.

I then made sure the sprocket sizing was correct by fitting the chain.

The cable drum was then turned and a spigot was made on which to mount the components.

The winch was glued together with CA.

Small pins were then turned and glued in the holes of the break lugs. You can just about see the treads on the .040" rod passing through the lugs. The right hand one is fitted in the next photo.

The break hand wheel bracket was made having done a rudimentary sketch.

The compound vice came in handy for cutting the angles. 

The brackets were formed in tandem.

Before being slit off.

Hello Keith,  Good to see an update on the Tennessee - it’s a nice looking model.  Sorry I can’t offer anything on the mystery object.  It makes me think of a tank for compressed air.  Hopefully someone will come up with an answer for you.  Keep at it and keep healthy.
 
Gary

Sweet work on the deckhouse and the brake portion of the anchor winches.  Beautiful work Keith.
 
Gary

Isn’t it great when machining comes an art, lovely job you are doing 👍👌
 
Where does someone buy these small buttons?

Pat, I'm working at 1:120 and while it can be very tedious, a lot of items less than 6 inches even 12 inches, depending on how intricate an item is, gets left off with the "sometimes less is more" thinking. Do you find at 1:72 you're compelled to replicate more so than not? 

"But try to understand, try to understand
Try, try, try to understand, I'm a magic lathe man"

Pat, I don't think that'll be an issue, just remember, I'm like Target, he's like Harrods. As far as the object in question being a crane, I don't think so for two reasons. One, location. That would make for a very awkward position between the two rifles plus it's awfully small for a crane. Second, see the photo below (you've got to be able to enlarge the heck out of it). There are only six lifeboats in every picture of the Tennessee that I've come across. But forward of the main there appears to be a set of davits on either side for another possible set of lifeboats or that's what I thought for a long time till I saw your comments somewhere herein on the subject of cranes and ash hauling. I now believe those are not supposed to be davits but are in fact used as cranes for offloading ash. The position makes sense because it's forward of both Dahlgren and Parrot rifle stations yet far enough to the rear of the bow Dahlgren so as to minimize wayward ash getting into the rifle mechanisms. I'm going to make two of the little buggers so stay tuned, we'll revisit the crane possibility afterward. I tried searching NMM Collections>Ship Plans>Equipment for drawings ZAZ6825 and ZAZ6824 without success? Thank you for the complement! 

My dear wife and I went into self imposed isolation last Thursday evening at 6 PM. It's a different world than it was a month ago for all of us. Keith, to you, yours, and to everyone here at MSW, I wish you all the very best in these difficult times. 

One of the deck elements that remains to be done is an Item that I have no idea what it is? It's stationed at the bulkhead between the two Dahlgren rifles. This is the starboard side view and I assume there is one on the port side as well. I think I can make it to a level of acceptability but I'd dearly love to know what it is I'm trying to replicate. Because of where it's stationed it must have to do with the rifles but then that's a guess. Anyone with any ideas please sing out. Thank you in advance. 

It's been awhile since I posted. I've been working on the Tennessee, it's just slow going these days.   In my last entry I was planning to make the yards next but I decided I first needed to complete all the deck elements, rigging lays many leagues ahead. I started by ripping out the pin rails, I wasn't happy with my first attempt. I'm in the process of correcting those along with adding ladders, deck cleats, fairleads, bollards, lifeboat davits and scores of eyebolts to the deck and bulkhead.    Bob found a permanent home on the starboard side of the flying bridge, he's studying a chart of the Pearl River, noting the corals to starboard of the entrance. (that's my story and I'm sticking to it)   Oh, bad news regarding the crew, Yellow Fever found it's way onboard and the crew has been quarantined to ship. The laughter of nut brown maidens will not be enjoyed during the Tennessee's time in Hawaiian waters.
