Manning Wardle Wheels

[david bigcheeseplant]

I am building a RT Models K class Manning Wardle, and decided the Gibson wheel were too chunky, so I drew up and designed my own new wheel centres had Modelu 3D print them for me. The wheels are fitted to Exactoscale tyres. My whhels have the correct ten spokes and a 2mm axle. The attached photo shows my wheel (right) compared to a Gibson wheel (left) The wheel is very small and the camera is cruel.

4mm scale?

Jim.

 

[david bigcheeseplant]

Yes 4mm scale 3 foot diameter so just over 12mm

 

[JimG]

Very nice work. Do you get a good push fit on the axles?

Jim.

 

[david bigcheeseplant]

The axle holes are printed 1.9mm so will be opened up to fit the 2mm axle using a reamer.

David,

I would be interested to see how you get on with the push fits. There has been some discussion about using 3D printing to produce driving wheel centres for the S Scale Society parts shelves but I haven't ventured forther down that road so far. We have our own limited range of finished loco wheel tyres and we could make others to different diameters, so there would be no problem with that part of the process. Which 3D printing company did you use - the quality does look good?

Jim,

Modelu. That's Alan Buttler who did the Heyside chimneys, milk crates, and milk bottles. He also has scanned and printed some figures, all of excellent quality, with less printing lines than I have seen on comparable prints.

I will use a taper reamer which is what I use on Gibson wheels anyway.

Modelu printed the wheels for me I think the printer prints to 3 microns and is better than Shapeways

David, Richard,

Thanks for the information. I might try and get the brain in gear and draw up a 3D file of a wheel centre to try out. I've got some 4' 6" steel tyres on the SSMRS parts shelf and the information on a Caledonian 4' 6" wheel which I've been using for the 1:32 scale driving wheels I'm making, so that might be a good subject to try.
