Please post your results with the Wiggytronics smoker when you get that far. I am very interested in how it performs. It might turn out that there are both cheaper and more effective solutions than mine.
Cheers,

For sure Chris I keep you informed.
Hopefuly I´l be ready with the reposition
off electronic´s in the weekend.

Smoke 'em out of their holes!
Gentlemen!
You are a most demanding group of skilled craftsmen who are very difficult to satisfy completely. When you say "nice smoke, Chris", nice means "barely acceptable" and there is no doubt that between the lines - WE WANT MORE SMOKE!
To meet up with these requirements, I have designed the eight cylinder Nuke smokem Hochleistungsrauchgerät HL210, which, just as the prototype, will wick upp any amount of fuel in no time and turn it into smoke.
Here are some photos from a session in the lab.
Burning down the house
This is the lab where the experiments were just conducted. The smoke never stops!
The blues
Here is a spy photo from inside the nuclear reactor, where you can see the four forward cylinders rising from the pool of fuel. There is an additional row behind them. The blue tint is typical for images taken inside a nuclear device such as this:
Here is what it looks like up close when in preheat mode:
Clouds up pretty quickly now.
Smoke gets in your eyes
Here, you can see the device from a distance, starting to "leak" smoke everywhere:
Panzer starten!
Some preheat time and it's finally time to start the engine:
The real thing
The engine has now been hoisted into the engine compartment and is ready for a start under prototypical conditions. However innocent looking, it is now advisable to wear a smoke mask when you trigger this video:
Smoke lingers long after, due to the size of the fan that takes half a minute to spin down.
Don't watch these clips repeatedly - it may be hazardous to your health - and be sure to go outside for a breath of fresh air!
Hopefully this will be enough smoke for outdoors - field testing is next.
If you can still read this, I wish to thank you for diving in.

The great outdoors!
Long time - no see (!)
The weekend was beautiful and I took the tiger out to see how the smoke would look outdoors. Here is the result:
It's still not as much as I had hoped due to the wind. Maybe twelve cylinders/smokers is ideal? Hmm...
Once there is less wind, it looks much better. - like here in the Antitank ditch:
I think this will have to do, so that I can move on to other things. The smoker has kept me busy for very long, but now everything is working reliably; no leaks, hoses stay in place, there is plenty of smoke every time, reliably, and the supply of oil will last quite a bit longer than the original 20 minutes.
The model smokes considerably more than the prototype, as you can see in this video, but this is one of those very rare occasions where fidelity has to yield for coolness

The only thing I would like to improve (besides more smoke...) is the fact that I can't see the fluid level. Fuel meter anyone?

Hi Chris
Great job
I think you nailed it really good .
Thats what I call a good smoke
Time to move on

Some work has been done on the commander's cupola. What you see here is Mike Stannard's upgrade kit:
Not perfect, but a considerable facelift. Too bad I managed to get it out of focus - you can't see how nicely I polished the details...
Inside:
The hatch now feels somewhat like the door of a bank vault. A hydraulic dampener would not be out of place...
Thanks for looking down the hatch,
/Chris

Urgent indeed!
The front sprockets have been without proper lubrication for long enough. It's jetzt time to install proper grease fittings like the ones seen on the Bovington tiger:
http://vincesgallery.smugmug.com/Histor ... 2176_uAXsY
I ordered some brass hex rod from Knupfer and turned in the lathe. It felt like a long lost return to my old 1/87 hobby. Only I could not quite see what I was doing. But the result came out good enough. I think. I can't quite see:
Pressing the part in place:
The grease fitting in place:
Installed on the tank:
Close up using the macro setting and squeezing the lens against the part (these tanks sure are small, arent't they?):
Thanks Per for the measurements!
The next fielding will be a lot less nervous!
Thanks for slip-sliding along!

Hi cahlfors
I like very much the work of detail you have done on the commander's cupola and the sprockets.
A thought about the smoke.
Are we sure our tanks need it?
How much?
I discussed this question here ( http://freeforumzone.leonardo.it/discus ... dd=9764548 ) . The title means " Is the smoke healthy … for our tanks?"
(I am sorry but I am not able to poste the videos).
As you can see there the tanks run in different way. Today they smoke a lot but yesterday they did not do the same.
I would like knowing your opinion.

Hi Pierluigi!
Good to see you back on the forum!
I elaborated on the topic a few posts up, where I also posted a sequence from the Bovington tiger for comparison. If I understand correctly, diesel engines smoke more than gasoline engines and the Maybachs used gasoline. I do think my model smokes more than the Bovington tiger, but mine is an early version with the HL210 engine. In the beginning, they consumed about 5L of oil per 10km. This was considered a bearable compromise to get the Tigers to the front subito. But I imagine that this oil would be consumed in smoke, so maybe my model produces a proper amount of smoke after all?
If not, it appears that a little too much smoke is better than too little? Or, at least, that seems to be what the audience wants and what would you not do for them!
But it is also difficult to make the smoke behave like on the prototype, where revving and changing gears will produce a puff of smoke and then it clears. The model smokes continuously. The tiger seems to be particularly difficult in that respect because of the deflectors that prevent the smoke from rising high. I have an extremely powerful fan in my model, but it still lacks the power to push the smoke very high.
Cheers,
/Chris
