Gear driven drill presses are true to their name. These machines use a gear box to transmit horsepower from the motor to the spindle. With an allgear drive transmission, there is only a 2% loss of torque between the motor and the tip of the cutting tool. This means that the system delivers 98% of the available motor torque to the cutting tool.

A Mazak QT20 lathe runs 120mm ID bearings on the spindle and has a spindle bore of ″. That works out to a wall thickness of about ″ or about 29mm. Now let's say we want to build a lathe spindle with a spindle bore of 2″. Let's give it a 1″ wall thickness, so we need bearings with 4″ ID which is 101mm.

Mount the electronics cabinet on the side or back of the column and connect your power supply. The head is fully wired and ready to go. The back geared heads are most popular because they deliver much more torque at low rpm. Top speed is 6,000 RPM. Use CATV40, BT40 or NMTBA40 tools on a Bridgeport format head with increased spindle rigidity.

The flat belt SB is the least subject to this problem. One of the great advantages of a flat belt is the fact that you can replace the belt without having to pull the spindle out of the headstock, as is required with the V belt Logan. These segmented Vbelts will remedy that problem, though, making them just as easy to replace as the flat belt.
