Thanks for the kind comments
Making your own wheels can prove to be a cost saver, to buy the wheels for this engine would be around £300. Ali plate and steel bar around £25
Yes; G3 track is available about £15 per yard
I made the gearbox from items found on e-bay total £20, there are commercial motor/gearbox’s available powerful enough for G3 but at cost around £150
I approach model making as a challenge, so why not take on as much as possible if you have the tools and equipment, plus you can cut the cost to a minimum.
