Darkmeat Finally Gets His Big Fat Head Around Offset.

[Darkmeat]

Fnkced up with the mental concept of offset?

So was I. Then, like a nail gun to the back of the head, inspiration struck!

 

Offset is indicated by the use of the initials ET.

ET is short for Einpresstiefe - a German word meaning 'Insertion Depth'.

Let's use it in a sentence:

In November 1941, the 4th Panzer Army's maximum Einpresstiefe was 30 km west of Moscow.

 

Now, to visualise offset, it helps to imagine Russia as a giant wheel arch, and the German 4th Panzer Army as a wheel (no, not a tank track).

At ET 0, the mounting face of the wheel hub is level with the half-way point between the inner and outer lips of the rim (say, near Minsk).

The further IN to the arch the wheel goes, the GREATER the Insertion Depth i.e +30 (Mocbah!)

The further OUT of the arch the wheel sits, the LESSER the Insertion Depth i.e -20 (Only as far as East Poland.) 

 

Adding a spacer moves the whole wheel further OUT, DECREASING the Insertion Depth (ET) ie. +35 to +25

Machining metal off the wheel hub mounting face moves the whole wheel further IN, INCREASING the Insertion Depth (ET) ie. -10 to -5

 

Next week, Darkmeat will explain the workings of the float valve, using Nelson's series of consecutive victories at

Copenhagen
Ushant
Nile &
Trafalgar

to illustrate.
