Wheel flanges

[HacksawParticipant @hacksaw]

I think i know the answer really … but i was having some thoughts..

 

 

Would there be enough meat on these roller door wheels to turn into loco wheels ? They're just shy of 75mm dia and 10mm wide .. The flange does appear to be cast a little thicker /deeper on the inner side , so that side would be the tread .

I was only thinking Kerr Stuart 060 diesel type , 12v battery , hand drill bevel gears , something simple anyway … !

Are you sure they are cast & not forged steel. Not sure the difference machining though.

All you ever wanted to know about wheels standards

you don't say what scale loco, but I think you'll struggle at 3.5"g

Yup, i hit it with a hammer and it broke one . only have 15 left ..

Alternatively you could turn up a separate tyre from steel tube and shrink or press it on.

I've often wondered – as 5" gauge models often share tracks with 3.5", and small 5"G wheels are smaller than large 3/.5"G ones, would the smaller 3.5"G flanges work and be more to scale for 5"G?

You might want to try an edge of the wheel with a file, often cast wheels and casters were purposely chilled around the edge for better wear resistance

I bunged one in my lathe this morning , it turns beautifully .. Must be old English cast iron !! Not even a hard skin or blow hole .  Just messy black  mess…

The chart that Duncan linked to , says overall width of a 3 1/2 " gauge wheel is 0.375 " – 9.5 mm . I reckon it's possible ! There isn't any wobble – run out , a think they'll skim up ok and still be wide enough . However… the hand drill bevel gear is a larger diameter than my wheels..?? I hadn't thought about that ..Any way around that ?

LBSC in his write up for Canterbury Lamb, a very small 3½" loco says that he is returning to 'his' standard tread  width of 3/8" instead of using 5/16" like he specified for Rainhill – an earlier and even smaller 3½" loco. Later on he uses 5/16" tread width for the tender wheels. Tich also has wheels 5/16" tread width.

Please don't take this as being authoritative, a standard is a standard after all but there are locos with narrower wheels out there.

But tread width is not overall width of the wheel so the standard is 7/16" overall width with LBSC's slimmed down version 3/8" overall.

I've remembered , i have some smaller gears salvaged from an angle grinder …! They might do

Are those from a travelling ladder?
