Type of builds on this site

I found it interesting to note that the wheels on the full sized one in Michaels link has the strakes running the same way, could this be something to do with the way the gun recoils?

Or could be that it did not have anyone riding on it to get shaken to bits, the angled strakes ensure that one is always in contact with the ground so you get a smoother ride.

Interesting how the gun has traction engine type wheels, I guess in those days if large wheels were needed for heavy equipment that was the way to go.

Large wheels were essential on the mostly unmetalled and potholed roads of the day. Only towns were likely to have paved surfaces. Off road it was vital to have wheels that resisted sinking into soft ground as well as being able to move over rough ground. Traction engine wheels were the best option before technology produced big pneumatic tyres and caterpillar tracks. Traction wheels were far from ideal and they became deeply unpopular as soon as roads improved. They rip good road surfaces into shreds.

During WW2 the US Army suffered mass casualties due to a condition called 'Jeep Bottom'. Travelling long distances on hard badly vibrating jeep seats caused sores serious enough to require hospitalisation. Ouch!

Not all used large wheels, but maybe that's why they lost?

"Jeep Bottom"……. the things you learn about on a Model Engineering Forum

[I.M. OUTAHEREParticipant @i-m-outahere]

I reckon the guys in this video came away with "Jeep Bottom " and probably a few other serious injuries !

Thanks Jason ,Michael for the links, very helpful and interesting reading in more ways than one, that model is very nice and well made and gives me some thing to work to and may be improve on in some places, Jason that fowler and colours would suite the howitzer down to a T , i have already started this build so will see it out now till the finish when ever that may be ,think i'll start a build thread on this and see how i get on with what i have to work from

Tanks Mal.

XD 351, the Jeeps in the video were taking part in the acceptance trials(can't remember the name of the place), there was a whole lot more than driving over what looks like giant roofing iron, and no seat belts there, but maybe the drivers and crews came from the cavalry. Designed by the Bantam Car Co, the company who made the Austen 7 in USA.

The guy in the back hanging onto the spare wheel cracked me up ! I have seen a few of these videos where the look of terror on the faces of some of the passengers is priceless !

One thing for certain Mal is you arein for a riveting experience !
