Instructables

Build a 15,000 rpm Tesla Turbine using hard drive platters

Featured

Step 3: Make the shaft

This is just a piece of aluminum stock turned on a lathe. The center diameter is about .98" (which is the inside diameter of the platters) and about 1.77" long (so it will fit in a piece of 2" thick acrylic).

The thinner sections on each end are turned to fit the ball bearings I pulled from a box of scrap.
