Reprofile of Heljan diesel railbus wheels to finescale profile

Step by step, Richard, you are moving towards S7...

I was going to write, you cannot polish a tu*d, but ......

..... you can roll it in glitter - although quite how this might affect electrical pickup I couldn't really say.....

Careful Nick, just remember how you were gently nudged over the edge and look where you are now (operating S7 layout at a show)

And what a delight that was!

Not unlike Tesla which are polished but owned by a turd

I think the railbus is worth a photo. The newly-thinned wheels don't look so bad, but the misalignment of the axleboxes might be here forever.

After I made my last post, I realised I would not let myself be defeated. I had read somewhere the wheels are brass so they will turn easily. So I mounted them up in the 4-jaw chuck with a brass shim around the treads to discourage marking, and skimmed about 0.2 mm off the backs.

This has taken the B2B up to around 29.2 to 29.4 mm.

F/S standards state 29.00 mm btb but depending on the flange width this should be increased to get an o/a flange dimension of 30.75 mm.
As for the Slaters wagon wheel sets don't always assume they are correct, I've known S7 and F/S sets come out of the packet with varying dimensions so they should always be checked with a gauge.
