These change wheel tables apply to all Mini Lathes with:
- Metric 1.5mm pitch leadscrew
- Imperial 16TPI leadscrew
They also cover some slightly larger lathes with Metric 2mm pitch leadcrews sometimes referred to as 'mini lathes' but fo different design, including the SIEG SC4.
The tables cover most Metric, Imperial and BA threads.
Always do a check before cutting metal, as there is always a possibility of errors.
