Your Sign of Quality for 4mm Scale Wheels and Gears

Welcome to the Ultrascale Products web site

On this web site you will find information about Ultrascale products. Ultrascale is the name under which a range of 4mm scale items for modelling British outline steam and diesel locomotives is produced. This range includes the most common locomotive and rolling stock wheels and conversion packs for proprietary, ready to run locomotives. Most of these items can be supplied for either ‘OO’ Fine scale, E.M. or 18.83 gauges.

Here you will find the most recent conversions done at the request of customers. Using either a locomotive supplied by us or by the customer.

Accurascale
‘Pannier’ tank
Converted to 18.83 gauge.

The above model has been converted to 18.83. Using new scale wheels, a new brass final drive gear and axle bearings and balance weights have also been added to finish the model off.

The conversion need two other things doing. the first is that the brake pull rods on the outside need to be moved out otherwise they will rub on the front face of the tyre and second the rear sanding boxes behind the cab steps need the corner nearest the wheel filing down slightly so that the front face of the trailing driving wheels do not rub on the sanding boxes.

The above video is another customer commissioned conversion of an Accurascale 57xx to 18.83 gauge. But this time I have fitted the coupling rods from a Bachmann model (which the customer supplied) as these are jointed, unlike the Accurascale rods which are one solid rod.
