Weed Killer Wagon

One of the things that I really like about narrow gauge  industrial railways
is the variety of unusual pieces of rolling stock.

During a visit to the Penrhyn Castle railway museum I saw a wagon that had been built
for spraying weedkiller onto the track when the operating handle was pushed forward.

An unusual prototype that I thought would be ideal for modeling in 16mm scale, so here's the result.

Made from a one piece CNC machined oak chassis with a 3mm ply planked bed, the wheels are Slaters
and the axle boxes are IP Engineering. Some of the detail including the pump is 3D printed with the rest
being made from bits of brass and copper wire. And yes the drive belt is an elastic band :D

I assume this isn't a working model??

Seriously though folks, I have seen genuine weed killer wagons with a large tank and a gravity-fed "dribble bar" to keep the trackbed weed-free - somebody also built a wagon with a Strimmer unit on it, to cut back lineside vegitation (though I think that's a BIT OTT!

Nice model, anyway!

I want to make a flame gun to melt snow and ice..and see how many 3d plastic models I can wreck JOKING! :lol:

The pump drive works but I think the tank's a bit too small to be of much use.

I like the way you have added new technology to add to the more traditional materials I can see in use. It clearly doesn't have to be either/or with new techniques.

EDIT: Having looked at your other post on Fullersite wagons I suspect I am actually looking at a CNC machine oak chassis and not quite the stripwood a glue I thought it was! Still looks good!

Sorry I seemed to have missed that bit out of the description, corrected now. I find the one piece chassis is a
bit more stable than one made from strip wood, also easier (for me) to make and it doesn't disintegrate when you
apply the wire brush wheel to simulate the wear and tear.

Still really like it :)

Shows newer approaches can be just as convincing

I do like the oak for its grain and aged effect but would look better as seperate sole bars and head stocks as in real practice.

I can't see why, you can't see this on the prototype as its covered by the corner angles,
which I've just realized that I haven't put on my model, a job for tomorrow I think now ,
should I use brass strip and a centre punch or CAD and a bit of plastic :?:

Your gonna stick with your CAD and plastic! Shame sticking plastic on oak though. Rivet punch from metalsmith ltd which is a hand tool and some brass strip
