I needed to true the drive wheel of a 175 x 300mm (7" x 12") bandsaw that I restored a year ago. My lathe has a 250mm= 10" swing but the wheel is 300mm = 12" in diameter, so the lathe is not large enough.
But I realised that I could do this on my FP2 vertical head. It was even convenient, because the wheel shaft is 25mm, which meant I could just hold it in a 25mm collet.

Turning it worked well. Tool-holding was certainly rigid! On the last pass I reproduced the crown (about 0.2mm = 0.008" in diameter) on the wheel.
Here is a short "action video" of this process.
Cheers,
Bruce
