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. Also available is a range of worm and wheel gear sets and spur gears suitable for all scales.
We can also offer a bespoke gear cutting service, to produce gears outside the current range offered on the web site. We have also developed a number of mobile apps to help in the setup, production and checking of gears.
All items are produced to order, using manual production processes, which means that lead times can be long. (see 'Current Production Status' below)
It is with sadness that we announce the passing of Brian Rogers the founder of Gear Services (Letchworth) Ltd. and 'Ultrascale Products'. His contribution to the 4mm scale model railway world over the last 50 years, along with his vast engineering knowledge and railway modeling skills will be greatly missed.
We would also ask customers at this time to take into account the possibility that lead times could be longer than is currently stated.
Delivery Time
Due to the current 'Covid-19' lockdown situation that we have in the UK at this time. I'am not able give any accurate lead times for the production and supply of any products. Orders that I currently have will be supplied as and when the situation allows.
Our current delivery on production items can be up to
5 months
from receipt of order.
The following list shows products that are available to purchase from stock. Please note that this list will change, depending of the products that are available at the time.
New RTR Replacement Gears
We have now added a number of new gears for some of the Heljan 'O' gauge diesel range of models. These gears are a direct replacement for the original gears that have been found to split sometimes.
New gear for a Oxford Rail Janus
Customer commission to replace damaged nylon drive gear for an Oxford Rail Janus.
c1906 Private Owners Wagon, RCH Standard wagon with body and wood underframe.
The wagon has been produced using various materials and production processes. drawings, photos and other data to produce the wagon are sourced from a very useful publication 'Private Owner Wagons from the Ince Waggon & Ironworks Co' by A. J. Watts and published by The Historical Model Railway Society.
Prototype Gearbox Design & Construction System
Is a proposal for a modular gearbox design/construction system. The system uses 3D printed modules (blocs), which can be simply glued together to create a fully functional gearbox.
The current prototype has been developed for use with 'O' Gauge (7mm Scale) models. However, a 4mm scale version is currently being looked into.
The current system is divided in to three main sections, the Primary drive module, the Intermediate drive module and the Final drive module. (these are explained in greater detail below)
Dapol Streamlined Railcar
This was a customer commissioned job to convert the model to EM gauge. An 18.83 gauge set has also been done for this model.
Just a quick update to show the lastest of our prototype gearboxes with 3D printed case. This is a 38:1 worm and wheel box, the one with the fly wheel can have both input and output shafts remove with out having to dis-assemble the gear box.
