Goal: Make a small stand alone CNC mill with high rigidity.
The next item was to make a couple retaining plates that will keep the teflon sheet in place inside the quill block. Teflon sheet was used instead of bushings to make a tight but low friction surface to hold the quill. The spacers were made from nickel aluminum bronze.
Next the main drive motor support for the spindle was machined out. Unfortunately I did not take any pictures of making the main motor support while it was being made. After that I made the Z axis motor bracket. This bracket is also used to tension the belt for the quill drive. After that I made a belt guard to keep fingers out of the belt area.
Next the drive and driven pulleys were cut out on the lathe. Again Charlie made a cutter to put the groves in.
The main drive motor mount was put on the mill and the motor was hung from it. Then I cut out the moon shaped upper guard to keep the drive belt contain in case it ever flys off.
Driven pulley complete and installed
