The Jet 4224B lathe is manufactured using heavy gauge cast iron, this helps to minimise vibration and at 395kg this lathe stays rock solid even when turning very large diameter projects. The heavy duty headstock is designed to travel up and down the entire length of the lathe, which allows the turning of very large diameter work at the tailstock end of the lathe. Both headstock and tailstock have positive cam action locking and a safety spindle lock makes it easy to remove faceplates and chucks. Built-in indexing offers 48, 36 and 14 hole positions on the spindle. The 3 stage 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. The pivoting motor mount allows easy lifting of the motor for fast speed range changes. Three speed ranges are available 40-910, 80-2,000 and 140-3,500rpm the lower range enabling high torque at very low rpm. With electronic speed control via an inverter, you can fine tune the speed of the lathe by the turn of a knob. Comparator centres for copy work are a very useful feature as is the neat storage compartment in the tailstock. The tailstock quill thread has been upgraded from the previous model and it now features an acme style thread which adds extra support when drilling with a tailstock chuck in place. A vacuum chucking facility is a real bonus on this lathe and it operates using a compressor (not supplied) to generate the vacuum via a venturi connection. A 1,600mm bed extension with a leg stand and a 500mm bed extension are available as optional extras and the shorter unit can be used in two positions, the lower position giving a massive 48" (1,220mm) capacity (24" centre height above the extension). If you want to buy an industrial quality lathe that will not need upgrading at a later date, then this lathe would make a sound investment.
Supplied with four pronged drive centre, revolving tailstock centre, knockout bar with brass tip, 75mm faceplate, faceplate spanner and a 350mm tool rest.
Optional accessories: 1,600mm extension bed with leg stand, 500mm bed extension, riser block for tailstock assembly, heavy duty outboard turning stand and a 150mm tool rest.

long term experience not so good.3 years on I have now removed this lathe from my workshop. My biggest issue was that I could not keep the toolrest tight. No matter how I adjusted the clamp it would easily move unless I placed excessive pressure when locking it up. I was told that I had not adjusted it properly but having demonstrated on many of these around the world they all have the same issue. The banjo is bulky and not easily moved and it is hard to avoid contact with the rim of the bowl with it's sharp corners.

Jet 4224B lathePowerful, versatile, smooth and rock solid are words I would use to describe the Jet 4224B. I have put this lathe to the test and it is here to stay.
