    Very nice design and build. What are the specs for the two rear gears? Did you make these or sourced the gears from a supplier like Boston Gear?

    Thanks for the comment Paul Jones! I made the gears myself. The larger gear has 84 teeth and the smaller gear has 21 teeth. I used a 1.25 mm metric module.

    Very nice. Could you describe your bearings and how, of if, you preload them.

    Thanks for the comment Saltfever!The bearings used are 6006 2Z number. Preload equal to 37 N (3.8 kgf) carried out through the weight of the plate and the spindle (satisfactory value for a maximum rotation equal to 500 rpm).
