Thought this might be of interest to those of us who find difficulty with Chinese versions of English as applied to tool descriptions/instructions. I noticed a question on another site about fitting a dividing plate to a Vertex rotary table and the writer obviously had the same difficulty. The following is a description of the procedure to follow. In particular, it refers to the Vertex 4"/6" RT and the Vertex set of division plates.
1. Remove allen screw (turning anti-clockwise) and washer securing the hand wheel on the rotary table.
2. Remove hand wheel and micro collar - take care not to loose the woodruff key on the shaft. Be aware that if the wheel and micro collar are separated, the small round brass pad under the hex socket screw can drop out and be lost.
3. Attach a division plate to the spindle mount (vernier collar) using the three screws supplied.
4. Push the sector arms on to the spindle as a unit with the screw and washer facing towards operator and the tapered portions of the arms facing each other to form a ‘V’.
5. Remove (or slacken) the screw and washer on the sector arms.
6. Insert the fingers of the special washer into the groove on the spindle with the bent tag facing the operator.
7. Replace the screw and washer and nip up.
8. Attach the crank handle with detent unit to the spindle using the allen screw and washer so that the pin will freely enter a hole on the selected circle of holes - if the pin will not reach the plate, slacken the retaining allen grub screw in the arm and move the unit forward in its hole until it does - tighten the grub screw. The pin should be between the sector arms.
An example: If we require 25 divisions, the tables state that plate A and the 20 circle of holes is required. Each one of the 25 divisions requires 3 full turns of the handle plus an additional 12 holes.
9. Enter the detent pin in one of the holes.
10. Move the the left finger clockwise until the taper edge touches the pin. Move the other finger clockwise until the 12th hole from the pin is wholly visible at the taper edge (i.e., the finger has now moved 12 spaces).
11. Lock the arms with the screw/washer. They are now locked together but will revolve on the shaft as a unit.
12. Disengage the detent pin fully and rotate the crank handle clockwise three complete turns and continue until the detent pin is over the hole adjacent to the right finger. The pin has now moved 3 full turns plus 12 holes.
13. Engage the pin in the hole.
14. Move the locked fingers clockwise until the left finger again stops at the pin.
15. Repeat from #12 until all 25 divisions have been completed.
I have a Vertex 4" RT and found that the spring on my detent plunger, as supplied, was too strong. There was a tendency for the pin to catch and move the sector fingers when the crank handle was rotated. A less powerful spring has been installed and the problem sorted.
Hope this helps to clear up a few of the problems encountered,
Ed.
