Atlas MF mill spindle pulley conversion????
The MFA had 3-step pulleys and was a 12 speed machine. The MFB and MFC had two step pulleys and was an 8 speed machine. Unfortunately, the 2 step pulleys are going to be far easier to find. The MFB and MFC together were in procuction for more than 15 years, versus about two years each for the earlier ones.

How to Build a Pulley (with Pictures)
1. Place 2 cardboard boxes across from one another on a raised surface. Use 2 boxes that are the same size and thickness, such as cereal or packing boxes. Set the boxes on a flat surface, like a table, so they're about 5–6 in (13–15 cm) apart. Make sure the edges of the boxes are parallel with one another.

Machining pulleys for toothed belts
It measures 2 1/2" in diameter. The pulley part number is A6A25-040NFO910. The belt is 8mm wide and is Gates part number HTD5M922366SS. I would need a different length of belt, but that width would probably do. Last edited by brian Rupnow; 11-03-2019, 04:17 PM . Brian Rupnow.

Pulley: Definition, Types, Examples and Diagrams
What is a Pulley. A pulley is a simple machine consisting of a wheel rotating about its axle. It is constructed by looping a rope or a cable around the groove of the wheel. Therefore, the three main parts of a pulley are the wheel, axle, and rope. A pulley is used for lifting heavy objects by applying force at one end of the rope.
