I would keep the 9x20.
but for the record, the 7x12 I have is a great little lathe. I have been able to keep my work within .0005" if I pay attention to accuracy. Most of the stuff i do is not critical with measurements, so i dont bother with that. The motor on my Homier is labeled as 400w and 4/5HP. I can stop it with my hand at the lowest possible speed which i think is 30-40RPM. After 50 or so torque jumps up |
