Hi
I am sorry it will never be sold.
I have made a statement of intent and I have to stick to it.
There are to be 25 hulls only.
These are numbered.
19 to go.

Regards
Philip

Phill goes on the say :-
At this stage mark out the position of the Bilge keels
Image
Image
Touchdown point is were the brass and the hull touch before parting.
Image
Cut to length
Image
Bending the brass to fit the hull
Image
Image
A perfect fit . Note the keel is dead straight.
Image
More to come

what about black powder guns that good BOOM!!!!!

Reid Thumbs Up
By the way, your picture cause a big discussion in a german forum HOW TO build such a function.
http://forum-marinearchiv.de/smf/index. ... w.html#new

Latest thougt: Take 2mm Berloque-Amunition to ignite smokepowder and cause that effect. Blackpowder is far too dirty!

Problem in germany are the strict laws concerning everything that has to do with weapons and explosives. Therefor even such a small plaything has to be approved by authority

Phil,
I congratulate you on your neat installation of the motors etc. Mine look like I threw a load of spaghetti inside and hoped for the best, but I'm gradually learning otherwise.

I'm following your build with interest as whenfinished your 'Bismarck' will be a very impressive piece of art.

More power to your elbow!

Curious why an ESC for each motor, is it due to load or to provide individual control?

Bismarck 1:72 Why 3 ESC's

Posted: Tue Mar 06, 2007 8:58 pm
by Kiwimedic
The three ESC's are purely for control.
If you have a computerised Radio Set you will be able to manouvre the vessel on the Right hand stick. This will give you proportional engine steer.Bismarck will have the ability to rotate in it's own length.
(Once you have had it with a multi prop you will never do without it again.)
You will stilll have normal rudder control on the Left hand stick. You can use all of it(Rudder and engines) together and realy make it turn.
The power plants are Buhlers and I am running 24Volts through them and at dead stall (Use a spanner to hold the shaft.) they draw about 3 amps.
Hope this helps!

Notch out keel for bolt. Do not flush solder or weld as it will not be strong enough.
Image
All mounted up
Image
Easy Flow them into place.
Image
Once that is done file them down to the shape of the keel. Now invisible
Image
Mark out position on hull and drill holes in hull for mounting.
Image
Just sitting there not bolted up
Image
Tightened up. Ready for bonding into position.
Image
Looking good. Note: Keels or all brass work to be painted must be etch primed. If not the paint will not stick well.

Cool! What do you mean by etch primed. What is etch primer?

Bismarck Build. Etch Primer

Posted: Thu Mar 08, 2007 11:50 am
by Kiwimedic
Hi
(To Etch, is a chemical reaction that microscopically marks the surface to make it rough for painting)
It makes a key in the metal surface so that paint has something to stick to It is used mainly with Aluminium and Brass.
The yellow undercoat you see on the fusilages and frames of aircraft is etch primer.
It comes in many colours.
Hope it helps
Philip.

VERY nice details. Maybe you publish also image details e.g. the grill and the anodes.

Although I have concentrated my interest on the imperial era (also for political reasons, as I have problems in identifying with the DKM) I must admit everytime that Bismarck/Tirpitz are real beauties!

Stanchions from James Lane. Note offset of lower chain holes.
Image
Two intakes with mesh. The frames are angled in as they are supposed to be.
Image
Progress.
Image
Primer added. They are just sitting in the holes as they need tapping home to a tight fit.

Are you doing it RC? If yes, WHY? Make a seat and a periscope in a main gun director, and you'll be fine!

Bismarck Build. Sea Chest Intakes/Exhausts.

Posted: Mon May 07, 2007 1:17 pm
by Kiwimedic
Dear All
I have been a bit quiet lately.
I have been to Dortmund, to the Model Show. Thanks to Guido and Dave Wooley for their help.
I made an alarming discovery. The intake/Exhausts in the Sea Chests are wrong! I was lucky enough to View an extensive set of albums on Bismarck. (The last few photos showing the intakes should be dis-regarded.)
When I arrived home the first thing I did was rip the old ones out. It has taken me a long time to construct new intakes etc. They are very fiddley and on a few occasions I ruined 6 hours work in 2 seconds. Once they were made they were installed and the damage from the old ones was repaired at the same time.
At the moment I am installing the Brass Casting Fairleads and the Anchor Clusses, also in Brass. These are exact copies of the originals.

I have also decided to add the detailing of the rivets on Bismarck, along with the lighter armour belting not usually seen on models.
(Yes folks Bismarck does have some rivets.)

There is a saying: You have not made anything until you have made it at least twice.
Dave will down load some photos when he can.
Regards
Phil
