great job!

Very good job; I like it, very much.

Wonderful job !

When I see this genre of masterpieces, I think  I don't will arrive ever, to this level.

Congratulations

What is selinic acid?  I must try with vinegar, before other method

Consider that using  30% hydrochloric acid and ammonia is fast and safe, if you use it outdoor, and protected by a mask.

You don't have to put your face over and it is not explosive.

The most interesting thing is that if you make a mistake or do not like, you can always go back the cotton swab with the acid and start over.

I protect my eyes and my face with a mask, and try it outdoor 

Hi shipmates,
I finished today to coppering my Connie with copper-tape. I used a poncewheel in the rear face of the tape, to relief the heads of the rivets.
Now the problem is to make old the copper.

I tried with 30% hydrochloric acid only, with ammonia only, hydrogen peroxide, and sodium hypochlorite

Best results is using first a cotton swab with 30% hydrochloric acid, followed by a second swab with ammonia.

The contact time of the acid -swab must be short, otherwise it corrodes the copper. (first test upward)

Immediately after you have to put ammonia with another cotton swab.

I did several tests (as in the photo) and it can get a nice blue-green shades....

During tests, I've seen smoke after the contact between acid and ammonia. Don't breathe it, because it is toxic.

I used it like a scraper, just like said by david b. 

You must use the lathe with low speed, and the "scraper " must be very sharp.

hello richard,
I've done it this way
I took a used cutter-spare- blade. I shaped it with a diamond wheel mounted on the drill, so as to give a profile equal to that of the cannon.Then I used it for turning, so the guns are equal.

I totally agree with  maggsl 01.

I have DB 250 too, and I'm very satisfied.  I worked on cannons, cabestan, masts, with great accuracy. 

I didn't work on metal, I believe it is not suitable for it.

I thought about this tool, to facilitate the winding ropes:

it is a simple tool. Just a wood strip in advance, with two holes where I glue two pins, and a notch at the tip.

it work very simply:

Ropes in advance must be wrapped around the two pins crossing

when the coil of rope is ready, it can be wrapped around the pins

Just a little mistake, Joachim.

In Italy, we use as nickname "Il Vespucci", not "Amerigo".

Only for clarification.

Bye

very nice work.

Much compliments, Ricardo.

Very very nice carving.

I don't know the right way. If you have made your model without any type of painting, I think it is better to leave your carving as it is. This is only my simple opinion. 

I prefer the natural color of boxwood, but your carving is simply beautiful in any way you let it.

I don't know the reason.

But I think..... If we assume that water can pass between deck's wood, but also between hull's planking, it's obvious that caulking must be done also on the hull.

If so, caulking the hull is the only possibility.

Maybe that cauking is invisible, because the hull is varnished and/or plated with copper ?

Hi Giorgio,

I'm always astonished by your job.

Much compliments and happy new year

What I meant is that there are types of haemostats very delicate, without serrations, flat. We need to work on delicate blood vessels, imagine if they are not sensitive to our hobby.
Let's say that it is a bit expensive surgical instruments, but in my case for example, I can use old devices from the operating room where I work (I am a surgeon), they are old and used, but they are perfect for my uses

there are hundreds types of clamps, strong or delicate, as you want. You have to try in a medical shop, but also in a flea market, expecially russian or east european ones

You guys are right - it is somewhat satisfying to spend forever on a detail that may eventually be totally hidden.  At least I know it was done with care, if a little inefficiently.  No matter, at least it got done.  

 

It helps me a lot to set realistic goals for the day.  Sunday was good - I achieved installing the deck supports and the mast framing.

 

Next goal - cut and and properly the 4 support stanchions for the lower deck.  This will be tricky (for me) as the neither end is square since both the bottom and top are curved surfaces, yet I want the stanchions to be perfectly vertical.  If anyone has tips on ensuring a vertical stanchion, I'm all ears.  Much less making 4 line up with each other in the vertices of a rectangle.

Probably the problem can be solved by plywood-profile, cutted on the ship drawings . If you see the drawing plans, you have the right inclination of the inner side of the ship. You can cut a plywood-profile, with one side on the middle vertical line of the ship, the base on the floor of the ship, the external profile on the stanchions, and the ceiling such as upper side. When you have this profile, you can adjust it in the center line, and support the stanchions on the external side of the profile.

Good job Andy!  I like it very much

Both !      You can make the hardest work with bandsaw, and finish with scroll saw.

If I had  to choose, I buy a bandsaw. You can always finish with handscrollsaw., IMHO

Anyway, many tools can be self-built. 

If you have a drill, you have the engine and you can easily build others tools.

In my little experience, i believe that a drill is very important, and a tablesaw too.

If I have to do a ranking:

1) tablesaw

2) drill

3) scroll saw

4) sander

Then, if you have to spend a little money:

A bench drill machine, (that you can also adapt to drum sander or like a milling machine)

A lathe

I phoned to Ufficio Cerimoniale della Marina Militare di La Spezia. 

The next public open visit of Ship Vespucci, could be November 4, Armed Forces Day, and March 19, San Joseph Day Patron Saint of La Spezia.

(it must be confirmed, because cost containment.)

Another possibility can be to organize a group visit, by a group of international ship modellers, for example, and ask for authorization to Navy.

Meanwhile, I will telephone monday in the morning, and I will try to know the trip of Vespucci. It may be possible that you could meet during your sail trip. I will post the notice in the evening of monday.

Buon vento. (Have a good wind!)
