Hi Zak,
They will be very impressive once completed.
I know they will be an extremely focal diorama.
Well done,
Cheers,
Bigkev

Life has been getting in the way of modelling.
I have had a disaster with spraying the V2, after masking I am afraid the paint lifted in areas. I tries to rectify this but am most unhappy with the result.
At present the rocket is in a black sealed plastic bag covered in Mr Muscle Oven Cleaner.
I will remove the paint and try again.

Meanwhile, I am making a start on the Opel Blitz T-Stoff Tankwagen. This is the Italeri Opel Blitz truck with resin additions. I purchased the whole thing from Azimut models. They send the resin additions and the bits of the Italeri kit that are needed.
Here are all the bits.

The Opel Blitz Ausf S Kessel-Kw. 3t tanker carried the highly-volatile T-Stoff (85% hydrogen peroxide 560 gallons & 15% water 80 gallons) that, along with permanganate, powered the rockets steam turbo fuel pumps.
There was also the alcohol B-Stoff tanker version, which could carry 770 gallons. The vehicle was equipped with a rear pump, capacity 66 gallons per minute, and a hand pump 21 gallons per minute. Weight loaded 13,000 lb. It would require at least 2 tanker trucks to fill the large alcohol tank on each V2. Three trucks could fill 2 rockets.

Often wondered how they were powered, a very potent cocktail of chemicals there.  Fascinating build zak

Meanwhile, back in the paint shop - well the other corner of the room, I have painted the V2 with dunkelgalb.
We are away for the weekend so I shall leave it until Tuesday before masking and painting further colours.

Especially for Mr Ward, here is a summary of Stoff.

STOFF
A -Stoff liquid oxygen (teargas was called this in WW1)
B-Stoff ethanol and water mixture
C-Stoff-
Methanol CH3OH   ~57% by Weight
Hydrazine hydrate N2H4 H2O   ~30% by Weight
Water H2O   ~13% by Weight
Catalyst 431   K3[Cu(CN)4]     potassium-cuprous cyanide coordination complex


F-Stoff Titanium tetrachloride
K-Stoff- methylchromoformate
M-Stoff- methanol
N-Stoff chlorine trifluoride
R-Stoff or Tonka: 57% monoxylidene oxide / 43% triethylamine
S-Stoff: 90% nitric acid / 10% sulphuric acid or 96% nitric acid / 4% ferric chloride (The ferric chloride acted as a catalyst.)
T-Stoff- hydrogen peroxide mixture
U-Stoff-dinitrogen tetroxide
X-Stoff-tetranitromethane
Z-Stoff-calcium permanganate / sodium permanganate / water

Now that you are fully Stoffed, its back to modelling. Sorry as an ex-chemistry teacher I still like to spell sulfur as sulphur (or is it my Britishness?)

Hi Zak,

An ex-chemistry teacher has come up trumps.

I'm going to save that post as a reference point, for anything of German origin dealing with experimental rocket engines.
You are the Stoffer of Stof's!!
Cheers,
Bigkev

Sorry Kevin I have missed out some Stoff - those with double letters.

Some of those I have given you were used earlier for other Stoff, as well as the tear gas one.

Keep tuned for other Stoff.

Hi Zak,
That looks like it will be a nice vehicle, once complete.
Will it be 'stoffed' with detail.

Thinking about the size of the 2 bases added together -- could this be BIG STOFF  ????
