The Powermatic 3520B lathe is one of the very best large lathes around from a top USA brand.
Equipped with precision ground bedway, the headstock and tailstock are heavy section cast iron with positive cam action locking devices. The heavy duty cast iron headstock is designed to travel up and down the entire length of the bed of the lathe, which allows the turning of very large diameter work at the tailstock end of the lathe. The safety spindle lock makes it easy to remove faceplates and chucks, and built in indexing, offers 36 positions (10°) on the spindle.
The 2-step, 10 groove Poly-V belt transmits full power from the motor to the spindle at all speeds while providing extra long belt life and ultra smooth running. A forward and reverse switch is a useful feature, especially when sanding timbers with interlocking grain and the ergonomic handles allow easy lifting of the motor for fast speed range changes. Two ratios are available enabling high torque at low rpm and with electronic speed control via an inverter; you can fine tune the speed of the lathe to suit the work in hand by the turn of a knob. The magnetic remote STOP switch can be positioned anywhere along the lathe bed for convenient use.
Comparator centres for copy work are a very useful feature, mounted in cast iron brackets secured to the headstock and tailstock castings. The tailstock has a laser etched scale on the barrel, and is self ejecting. The ACME type thread resists loadings and is very smooth in operation.
The 460mm bed extension is available as an optional extra and can be attached in 2 positions, the lower position giving a massive 490mm(19.1/4") centre height above the extension.
If you want to buy a great lathe that will not need upgrading at a later date, then this lathe is a sound investment.
N.B. The distance between centres will vary and be dependent on the type of centres or accessories used.
