Out of Africa! (Or Letters from Uncle Dick)

For discussion of the issues faced when building a model or layout - how to replicate wood, what glues to use, exactly how much weathering can a Gnat take, a good source of detailing accessories - you get the picture, I'm sure.

Yes I Gnow that but I sure wouldn't want to drive one on a slippery slope. When I was on my Scorpion light tank drivers course we stopped for a brew of tea. We stopped in the middle of an open clay area so we could fire up the chuffer. As we were standing beside the vehicles waiting for the water to boil we suddenly realised one was slowly sliding away with the tracks completely locked. The vehicle in question had a set of tracks that were worn almost smooth and were due to be replaced a few days later. The clay pan was damp and had a very slight slope - gravity took over :shock:

G,day....I was travelling a Cat. D6 across a side slope of about 30deg. one day. Came upon some trees that had been felled down the slope, well without thinking I started to cross the still green trees. What a ride sideways down that slope :shock:. I was definitely in need of a change of jocks :oops:

Well, made it "home" ok, so between the showers managed to get some paint on the machine :D

Now I am absolutely envious,

You have done a superb job,details character everything just fantastic.If I did not have 3 locos in the works I might be tempted to start one like yours.

“Uncle Dicks” Letters keep coming ( slowly) though in deference to the “Political Correctness Police” I have had to edit (Censor) them far more severely than in the past. I must also apologise to the nitpickers that I am working in 1:24 scale on 18.2 gauge track representing 18inch & 500mm prototypes. Where really I should be using 19.2 mm & 20.833mm gauges. Or I suppose I could scour the globe for 436.8 mm/ 17.1968 inch gauge prototype? Any way enough of this ****. [tongue very firmly in cheek :lol: ]
On to the latest missive;. ……………..one of the original JV partners in this project where ***** [from a North European Country] They had imported some compressed air equipment from the ***** [ a Scandinavian Country] One of the locomotives was never very successful being only a single axle drive. By a dint of ***lish ingenuity re-bar , air motors from a rock drill & some chain we converted it to a chain drive four coupled loco. Bit of snag now, the compressors gone and broke!..................


Back in August 2008 Henrik Laurel posted the drawing & some links to the prototype for this loco. (I must stop building locos!) see:
http://forum.gn15.info/viewtopic.php?t= ... =atlas+air
(Gerry you did ask!)
Well I have made a bit of a start. The bulk of the loco is built from Evergreen styrene, the hard part was finding some thing to make the domed ends from. Eventually I found that the cap off a can of aerosol deodorant was about the right profile. Now you can guess what, its taken nearly 18 months to find a second can with the same shape cap! Having now found both it’s a mater of sanding the moulded makers marks off the cap and lining the inside of the “boiler” (air receiver) so that the ends are a tight push fit. (Seems to be made from some type of plastic that resists all sorts of adhesive I have had to put some stops inside the barrel to stop the ends being pushed to far in.

Nice Job Trevor, I remember that loco the Henrik posted, it is one of the locos on my list of to do's. You are doing a sharp job of following the prototype. The whole glueing foreign plastic components is a real pain sometimes. I have found that roughing up the surface really well and using 5 minute epoxy seems to be as good as anything.

Looks good Trevor, I have a soft spot for air locos :)

Its certainly got to concentrate the drivers mind sitting alongside that size of Air Cylinder :wink:

On a more serious note, I am going to check out your maths re gauge /scale combinations, I should warn you if I do find errors I will report you :lol:

With my very limited range of paint I decided to put some colour on before I start to add the control details. (Lots pipe, valves & other bits-n-bobs.)

That's looking great Trevor.

I can't think why I have not been more impressed/interested by compressed air locos before now. I certainly hugely enjoyed this loco

Image

in 16mm scale at Telford the other day. (note link for pic is an unshamed snatch from Bobblackcloud's pics in this thread http://forum.gn15.info/viewtopic.php?t= ... ht=telford

- he took far more and better pics than I did :twisted: )


Apart from the difficulty, as you have found, of getting the right shape for the ends, they have a delightful simplicity to them.

As a further aside the chap who built the Telford model said the real thing only had the ability to do around 250 yds per compressed air load, but that this was fine for a bit of shunting, apart from which it could be 'refueled' in next to no time.

OH NO, not another 'Kettle' :lol:
Many moons ago I came across a drawing by Jim Fainges of a three (3) ton Decauville 0-4-0T. At just under 9 foot long, and 4 foot wide it doesnt seem impossibly large for an 18" gauge loco. An in 1:24 scale just over 4 inches (110mm) long. There where lot of French influence in West Africa,
So whose to say an 18" gauge one didnt find it was to where my layout is supposed to be based? I have made a start. Here it is as a "kit" of parts. I have to make it this way (in the vien of flat pack furniture.) so it can be carried home in my Laptop bag. (I travel light...............) The parts plug together using a simple plug-n-socket arrangement. The real challenge for this will be finding some thing to make the smoke box door from.

Image

Then put together (with the aid of some scotch tape :shock: )

Boiler, cab etc to come.
No running gear, that will have to wait until I am back in the UK .

Ooohh, so very nice pictures! Candy for my eyes !!

Someone who actually made something out of those atlas photos I took, great Trevor !!

Wish I could follow your example soon, but a lot on my wishlist before I reach that.

Next project the little Decauville loco, looks great to!

good luck with that, I tend to feel that 'interesting' or unusual items in hand baggage should be avoided in West Africa unless you have a suitable supply of small-denomination Euro banknotes available to hand... I have had some quite trying experiences transporting the sort of small electronic items surveyors tend to be involved with, at the behest of happy souls at Head Office who think Brazzaville or Pointe Noire is like Schiphol, except without Murphy's bar and the body scanners!

nice model, though. I've lately been in Russia and there is a small, pocket-size mossie repellent sold there which would be just the size for a smokebox door...what about those small snuff tins Scandinavians often have?

As there were 50cm gauge versions (one now on the CF Tarn in France), as well as 60cm gauge, then it seems possible that 18inch could have been built.

Your ref to Jim Fainges made me look him up on Google. I assume that you got the drawing from http://www.zelmeroz.com/albumquery/FaingesJ.htm.

What a collection of drawings. All I can say is WOW :!: :D

Well there was a bit more modelling time over the last few days (and the will to get on! :shock: )

Well a couple more more pics.


The rivets are made by embossing the plastic from the back.

The chimney (rolled from 0.015" sheet) is not fixed which makes it look a little lop sided.....
