You really need a multimeter instead of throwing parts at it.

I second the multi-meter suggestion. Check for voltage going into the circuit board, then check to see if voltage is coming out of the circuit board to the motor. If no voltage is registering at the power leads to the motor, then backtrack to the separate components like speed control rheostats, etc.
Look for "smoked/burnt" leads, junction connectors, etc.

Do you have the schematic diagram for the mill? If so, please post a pic. The first thing I would check is the safety interlocks, if it has any.
might try moving the variable speed rheostat back and forth several times with power off to see if its not making good contact. sometimes that will help clean it up if it gets burnt in one spot or has dirt in it
Do these have start capacitors? Is it making huming noises or anything? Hopefully it's something simple.
Is this black thing in the center of the picture the fuse or a resettable circuit breaker that you push in to reset? I wish I was closer, I could find your problem easily with my meter.
Looks like the paddle switch in the diagram. Which has a switch disabling key.
Those old brush leads sure look like they got hot. Sometimes new brushes don't seat well.
May want to revisit the brushes. Especially if the commutator got heated up too much.

I just bought a multimeter, don't know how to use it lol... I guess youtube will be my teacher lol.
That looks nothing like my machine. Mine has only a knob where the fuse is housed in.
