The steering carriage was added because of difficulties in steering.
Its not actually part of the original design but became a necessity
and was carried over to the Mk 1 design.

It was hydraulic operated and probably worked more like
a rudder, digging into the ground.

I did not intend on including it, but I have thought about creating
the add-on at a later date.

Almost a hundred years ago 1915, according to the Tank Museum video.
Interesting choice as well as the scale. 1:18th.

Are you going to put a turret as the original design prototype envisioned?
The tracks are always a test in patience. Have fun doing all those rivets too!

No Turret...I think I am just going to design it like the configuration
in the attached photo.
The Tank is obviously well tested in this photo, so the intended Turret
and steering carriage are not integral parts of the early design.

And this is how Willie is on display at the Bovington Tank Museum

"Farm Equipment." Uh - HUH.

Trivia quiz: anybody know the original reasoning behind the curvature of the track bottom?

Less ground contact (on level ground anyway) means less swiveling resistance.
In other words, easier to turn the vehicle.

So, where does the ice cream dispenser go?

Cheers!

Nice, but there's more:

Some guy was looking at how to get across enemy trenches in a hurry. He factored in the usual trench width & worked out what size of carriage it'd take to roll a certain usable mass across that gap at so-&-so speed...worked out to something like 54 feet diameter, if I recall.

The guys developing these vehicles (they called 'em "tanks" as a little deceptive camouflage) looked at those numbers, & thought: Hmm, it matters less if the center of mass isn't at the center of that wheel's roatation, the physics still apply - and a lower center of mass even works the numbers better!

Thus, you got the roly-poly rocker based on that 27' radius, rather than a simple short-flat center area. Pretty kinky, huh?

Little Willie was officially first called 'The Lincoln No.1 Machine' and had modified Bullock track, because it used off the shelf parts in the design it only took something like 30 days to build. The track performed badly over rough ground and a new track was developed.

The photo shows the building of the machine at Fosters factory. Note that the mock turret is being fitted, the hand drill, and the portholes are not yet cut in the hull, why the Naval terms? This was a Naval project, a Landship. The Army liked their horses.

The photo is from Richard Pullen's book Landships of Lincoln.
