Fooling Around with Kiwi Trains: Adventures in 3D Modeling & Printing (1:120 - 1:8 Scale) - N, HO, O, G, 5inch, 7.25inch & 15inch Gauges! No Ads, Just Some Nutty Tales from Peter Bryant @ Portland Railroad, Northland NZ
Now the printer's up & running I've decided I'd print out the DQ in 1:24 scale why not.
Most of the long hood printed.
The main sections finished
Most of the body printed, undergoing putty & sanding
Most of the body printed, undergoing putty & sanding
Dq after a paint job, dunno why but the masking was a bit of a miss, lots of tidying up to do. The cab needs another going over with the sand paper, eventually we'll get there.
Chassis fitted & wired up ready for a run in
Midway through detailing the 1:24 DQ Class, handrails are the thinnest my printer can handle. Nice straight lines, still much to do.
Over the past week I had been drawing up & printing out a Usl Log wagon, after the first few failed attempts at printing the flat sections I changed the print orientation to vertical & found better results.
Since I'm going to want a few of them I've managed to get the print time down to 3 nights for the main body.
Bogies are standard bachman freight trucks.
Drawn up in Tinkercad
Main body & cradles & minor detailing printed, cradles sitting in position with a friction grip.
Decalling finished although the cradles still unattached, still to paint the body & bogies red oxide colour.
3 Wagons completed, 48 individual decals for the cradles alone.
With a relatively smaller load but still looking the part
3d printed body sections printed, glued together & sanded. Everything fitted well, slight warpinig issues experienced a couple weeks ago during the cold snap but nice clean prints since.
1:24 Ew sections underway, sitting on bogies loaned from the De
Almost..
After a first coat of matt black, putty & sanding next.
Still in the process of printing the middle bogie adapter., another thing to consider is how sharp of a radius does it need to go around, 2ft would be the answer. Thus the implications are an exaggerated distance between to the two bodies.
The tidy up continues, Now is able to run. Been experimenting with printing pantographs, the pantograph base needs correcting so it can lower correctly. Just sitting in place atm.
Pantograph after a few tweaks, now completely lowers.
1:24 Ew making its first run
1:24 Ew, still far from perfect, join lines still visible but looking more like the prototype.
The next locomotive, 1951 NZR DF, English Electric.
Going to use 2x powered chassis & should be able to negotiate very small radius curves. Since the cowcatchers & couplers swing with the front bogie it will be an ideal heavy hauler for smaller curves.

7/8 sections, not far to go.
Body sections printed, Chassis next.
Sideframes just laying against their respective lgb power blocks. Pony trucks finished with plastic wheels, will need to add lots of weight until the steel wheels arrive
Pony truck & cow catchers not quite connected together yet, but main power bogies with frames finished. The body is too high by 18mm to allow the bogie swing, thus in theory allowing it to run around 3ft radius track.. Re printing the cow catchers slightly taller to make it look ok from the front.
A wee video of it running around 2ft track
Still with only 1 coat of paint, but looking much tidier with black sideframes.
