Making larger wheels for larger scale trains. This was produced for some larger South Australian trains like the SAR 620 and 520 class but would look at home on a lot other trains.
Don't scale your trains to the wheels, change your wheels to the scale.
Not just copies of injection molded parts, care has been taken to ensure 3D printed parts function correctly. Flanges are slightly thicker to stop de-lamination. Pin and axle sockets work properly. Will require a 36x1.5mm o-ring for traction.
I print with supports from base plate only and a 1 layer raft helps remove all supports quickly with one snap. The seams are scarf joined to help with roundness but still may need a small touch of a needle file
Post printing will require a 3/16" (4.8mm) drill though the pin socket. Axle socket will be tight and I kinda tap an axle through (back and forth) with a small hammer but afterwards should be usable and firm.
Wheels have 4 options to allow for different configurations:
Flanged with large counterweight
Flanged with small counterweight
Blind with large counterweight
Blind with small counterweight
Can be used with my ‘6 hole’ connecting rods
