Now I need to make a long part that allows me to attach the upper Wire-Chain to the Z-Axis slide. There was little space between the spindle body and the Z-Stepper motor, so making it out of aluminum was the best choice!
The part has a fork on the end to mate with the Wire-Chain, and a radius that matches the outer diameter of the spindle body. Then I had to drill a 5-inch deep hole 1/8 inch diameter to let the LED's wires to pass through. Then I mounted a tiny barrier strip under the fork, so the 12-VDC supply line can be attached to both LED's.
I took a nice picture from down-under, to show the two LED's ! The dust boot will need to be custom made to accommodate the LED's
