Since there are no instructions available for assembly of the 4th axis that I was able to find, I assembled my 4th axis by some logical guessing. Can other owners tell me if I got the assembly right? Here is how I did it:
1. Took the base plate and added the tail stock rail to it with two screws from the bottom into t track nuts. Slid the tail stock rail onto the t track nuts and tightened it down. 3 mm hex for this.
2. Added the motor to the aluminum bracket. Cord facing out. Used 4 screws inserted from the belt side through the aluminum bracket into the motor mount holes. I put nuts on the motor side but not completely tight.
3. Added the large pulley to the chuck almost all the way in.
4. Add the smaller pulley to the motor with the belt across both pulleys. Push on the motor until the belt is straight across both of the pulleys. I used a 2 mm hex to tighten the set screws of the pulleys.
5. Slide the motor over to tighten the belt up, then tightened all the motor screws/nuts down to lock it in place.
6. Screwed the motor/chuck to the base plate. 3 mm hex.
7. Assembled the tail stock (this is where I'm the most unsure if I did it correctly or not).
a. Installed the bearings in the v wheels exactly like the main machine build video shows (hammer in one bearing, add washer in the middle, hammer in the other bearing)
b. Put a v wheel on the shorter of the 4 screws, added the standard spacer, and screwed it into one side of the tail stock plate. The screws didn't extend past the plate and were just right. Repeat for the next one.
c. Put a v wheel on the longer of the 4 screws, added the eccentric spacer, but the screw/wheel/spacer through the plate. Added a washer and nut and tightened it down. Repeat for the other wheel.
8. Screw on the tail center piece to the tail stock plate.
9. The two remaining screws go on the back of the plate in order to lock the tail stock in place.
