Lucky Bob's is the HO emporium most of us UK HO racers use - another is JAGs Hobbies. If there are a few bits you need, there's usually an order pending - so just ask.

However, there's also Barry at Slot Cars Direct in Derby - he is the go-to guy for HO in the UK. In terms of pinions to fit a 1mm shaft, you're looking at:

• Life Like T pinion gear https://slotcarsdirect.com/shop#!/life-l...inion-gear
  
• Viper VSR088 pinion for Tomy Mega-G+ https://slotcarsdirect.com/shop#!/tomy-a...ole-mega-g
  

The new Micro Scalextric chassis also has the FN20 motor which runs great at 9 to 12 volts. No parts are available separately, but a rolling chassis would give you the motor, pinion and crown gear. More about the Micro chassis here: https://slotracer.online/community/showt...php?tid=69

There's also the older HO open cans - which were standard in the old Micro cars. Barry sells superior AFX versions of these. There have been used in a few 1/32 models over the years. The 1.5mm diameter shaft takes a standard HO pinion and the motors are less 'wild' to drive.
