Title: Addison A3 class steam landship : Group Photo
Post by: Camthalion on January 02, 2020, 07:13:39 PM
Our local club started a group build with the same base kit.  After much changing of ideas and such, came up with a simple one, I hope.  Make a steam driven vehicle of some type, yet to be finalised.  Probably changing scales to 1/35 as well.  The driver in these pics is 1/35.  Still a fair bit to go, but need it finished for our local show in February

That’s a good idea! Make sure the front wheels are steerable... and maybe think of the poor driver - not only will he have to contend with speeds of 40 mph or more (which many scientists believe will cause death by asphyxiation due to lathe speed) the lack of any sort of suspension will make for a bumpy ride. The side wings are a good place for the water ( or coal). Are you going to add a stoker?

That change of wheels really redirects the entire look of the vehicle. Great choice!

Oil-fired steamer to eliminate the need for a stoker?  Is it going to be a straight steam engine or will you be using a steam-turbine engine?

Thanks fellas.  Certainly some ideas to consider.  Very slack today after mowing the lawn, so thge only thing that has happened is I changed the wheels so the drive wheels are at the back

Yes was thinking oil fired.  currently fitting some pieces of my spares box together in my head, once thats finished, next time at the bench i'll mock it up. if it works that should give me a couple of cylinders for a reciprocating engine

So, cylinders driving the shaft or driving the wheels?  If the later, you might want to take a look at late-model steam locomotives and how their cylinders attach to their driving wheels.  Too, some of what the late-models ones have in regard to firebox and boiler design might be useful when scaled down.

If you wanted to keep it simple, chain drives seem pretty common on RW, old-timey steam cars.

That's what has slowed me down today and the fact I'm being lazy after mowing.  .  Trying to figure the positioning of the pieces and then to attach them add counterbalance weights etc. And while writing this I think I just came up with a solution to my steering problem,  but that is for tomorrow almost time to head to the club and my favourite bar stool.

A Possibility, particularly if my cylinders fail.

Some used chain drive, direct drive and shaft drive was also used, chain drive lasted longer
on IC engine vehicles.

Horizontally oriented engines were common, drawing looking down on a direct drive Stanley installation:

The Gardner-Serpollet was unusual in that it was a four-cylinder poppet-valve engine that used
superheated steam:

Carriages and wagons commonly had suspensions, the leaf-spring goes back to the 18th century,
the common elliptical type being patented to the very early 19th century (1804 in GB).
Steerable front axles are also old, the Ackerman system going back to the early 19th Century.

That's a fantastic concept. Kinda like Chitty-Chitty-Bang-Bang meets Le Mans.

Your imagination is just off the charts Cam and you seem to top yourself with each new model!

The prototype Addison landship  has under gone a major redesign into the A2 freighter.  From this the A3 Landship was developed to provide escort for military versions of the A2 in supply convoys. 
The A3 is still under production with much work to be done, gaps to  filled and fitting out etc.   Front axles are undergoing a redesign. 

so real life work has been getting in the way pf building, but got this bit done on my pajama day.  Smoke box and stack are from a 1/24?  Stephenson's Rocket, boiler is a HO scale railway bomb, forward superstructure is a hobbyboss T18 tank.  Still looks a complete mess, but getting there.

No pictures of the A2 cargo version as the only place that exists is in my head

I like how you've made all those different shapes work so well together.

The gas company logo on the tank is a nice touch!

Wasn't planning any more WIP shots, but the weather has put paid to any painting this morning.  Hopefully get the base coat on this afternoon. 
She is now turbine powered as the cylinders didn't work out.  Armed with an anti-tank rifle and a lewis gun.

Well, the Soviet MS-1/T-18 was based on the Renault FT  ;)

Keep getting flashes of Addison A3 in a movie.  Being its own character.  :smiley:

The pointy front is like the cherry on top for me.

Amazing how you got all these bits that shouldn't go together to work.

Thanks Fellas
And she is finished in time for tomorrow, I truly hated it after undercoat and first colour coat.  She's still a bit rough, but got there in the end

Best use of a Formula 1 kit I have ever seen.

Some inspired builds by the rest of the group as well.

Well done!
