wheel size accuracy?

[nigel jones 5Participant @nigeljones5]

im just completing the wheels for my 71/4 Invicta, thing is ive turned one a tad undersize. What sort of size difference will not cause me issues? thanks

Gnat's eyelash 'tad' or loose like a sausage in a rubber boot 'tad'?

A few thou won't matter IF your coupling rod holes are a little sloppy by the same sort of tad.

No coupling rods on an 0-2-2!

I would have thought the biggest problem is it will go round in circles if you try and run it without any rails

I'm sure I have read about full size engines occasionally having significant tyre diameter differences without ill-effects.

You could take the other one down to match maybe?

Once the wheels are n the axle, its best to give a final truing skim. Do both on the one setting
