It is not generally possible to use 00 'scale' wheels to model the
broad gauge, as the over scale treads and flanges will not fit within
the very limited clearances available. This limits the choice of wheels
that can be used, as Ultrascale are only available to order wih a huge
lead time, and Sharman Wheels are no longer available, having
disappeared into the Phoenix Precision Paints 'black hole'. Unless you
can aquire second hand product, Alan Gibson is the only option. The
Broad Gauge Society can supply a very limited range of wheels (2) at a

|Pinpoint axle length
||35.3mm (BGS ones nominal 35mm)
When I first started broad gauge modelling, pinpoint axles were not
available (out of stock with the BGS for years), so I had to make my own.
I turned down some steel rod in the lathe, and the result worked (sort
of), but I had trouble with the rod flexing while machining the ends, and making the pinpoints
off centre, which introduced wheel wobble. More recently I figured out
a much easier method, which does not require the use of a lathe.
In addition to a P4 gauge pinpoint wheelset, you will require some 2mm inside diameter brass tube from KS or similar (available on eBay). Just cut the existing wheelset in half, no need to remove the wheels from the axle - it doesn't need to be precise. Then cut a 27mm length of the brass tube using your back to back gauge as a guide (cut overlength and file back to be the same width as your gauge). Now just superglue the 2 half wheelsets into the ends of the tube.
