Hi, Welcome to factory !
The speed seems about right but I think a slower motor with a bigger motor pulley might give the saw more torque. From contributor R Your assessment of a slower motor with different pulleys would yield more torque is correct.
3. The motor, together with the two pulley disks weighs about 60 pounds and you are going to be in an awkward position as you remove it so be prepared. OK, lets begin. Step 1. It doesnt matter if you have the mill head in HI range or LOW torque range. With the Speed Change Handwheel, run the head down to its slowest speed.

Sep 03, 2015 The display now shows actual spindle speed for my particular belt and pulley configuration. If using multiple belt configurations and you have a chart showing the speed for those at a given motor RPM, changing the display to show percentage of RPM works nicely. This is achieved by changing the value to 1.66.
Apr 22, 2021 Pulley Definition is a Pulley is really a kind of wheel with two raised edges in which a belt or rope can run. It is used for reduction of force and its direction. Pulleys can transfer rotary motion from one shaft to another or can be used to lift hefty loads. Pulley is useful for moving, pulling, and lifting loads to make our heavy work easier.

Quickly set the pulley on the motor shaft and let the epoxy set-up Put the asembly back in the Arbor press and collapse the Spring and collar thread in the two 10-32 screws back on the varipulley so the spring stays collapsed. Put the assembly back on the motor. On the 2HP varipulley there is a small bore for the 10-32 screw that holds in the key.

As load is applied, the speed control will add power to attempt to hold a constant speed. Once the onoff switch is switched to the ON position, a speed control knob is used to vary the speed over the entire range. With the two-position pulley in the normal position on a Sherline headstock, the speed range is about 70 to 2800 RPM.
The pulley ratio of the belt drive kit has been engineered so that you can do all normal milling and drilling operations within the low speed pulley settings 0-1700 RPM, so you should not need to move the belt very often. By moving the belt up to the other set of pulleys you can run the spindle at high speed
Conversely, a small pulley driving a larger pulley will produce more power but lower speed. Variable-speed drill presses can reduce labor and boost productivity. The variable speed drive systems are a bit more complicated, and there are different mechanisms for changing the speeds.

The Tormach also has spindle speed and onoff under software control. Whereas, on my Taig, I have to flip the switch for onoff control, and change pulleys to change speeds. The pulleys give me 6 different speeds, from 1,050 to 10,600 RPM.
Im looking for information on building a band mill. I need to know what the band blade speed in feet per minute should be. Is there an actual set number I need this information to figure the pulley sizes from the output shaft to the input shaft of the band wheel. Im using a 14hp Kohler, 20 inch band wheels, 158 standard 1 14 band blade.
Dec 30, 2019 The 3 step pulley chart would be nice. But my machine has 4 steps spindle pulley 4 steps idler pulley and 3 steps on the motor. Not 4 I am thinking either the top pulley cover was replaced with one from a different machine or it has the wrong chart on it as suggested from the factory. I came up with speed from the tachometer method.
