'''In Phase 2''' • First on the list is to assemble a rotor of neodymium magnets onto the shaft. • Second on the list is to insert the rotor through the bearings securely into the disassembled wooden panels. • And third is to reattach the wood panels back onto the wood base blocks.

|Let's Build the S.H.O. Drive! - Slide 045 of 176.png||'''Neodymium Magnets''' ''(Phase 2 Parts)'' • We will need no windings on the rotor of the S.H.O. Drive. Instead the rotor of the S.H.O. Drive will be built using very strong magnets. • These magnets are an alloy of three atomic elements: • Neodymium (or Nd) (the 60th atomic element) • Boron (or B) (the 5th atomic element) • Iron (or Fe) (the 26th atomic element)
|Let's Build the S.H.O. Drive! - Slide 046 of 176.png||'''Neodymium Magnets''' ''(Phase 2 Parts)'' • These Neodymium magnets are from Magnet4less.com and are pound-for-pound some of the strongest permanent magnets that you yourself can buy on the market today. • These are often used in making wind turbine generators.
|Let's Build the S.H.O. Drive! - Slide 047 of 176.png||'''Neodymium Magnets''' ''(Phase 2 Parts)'' • Because these permanent magnets possess a stronger magnetic field, they will exert stronger magnetic forces on currents in S.H.O. coil. • In turn, the current in the wires will be able to exert stronger magnetic forces on these permanent magnets.

|Let's Build the S.H.O. Drive! - Slide 048 of 176.png||'''Securing the Shaft''' ''(Protocols)'' • To secure the shaft into place, I will thread some extra square nuts temporarily onto the shaft and clamp them down onto the Black & Decker Workmate with the Bessey XM7 3-Inch Metal Spring Clamp that I obtained from inside a Woodcraft store.
|Let's Build the S.H.O. Drive! - Slide 049 of 176.png||'''Magnetic Pole Detector''' ''(Measuring Equipment)'' • Before I attempt to attach the magnets to the rotor, I will identify the north pole of each magnet with a Magnetic Pole Detector that I purchased from Magnet4Less.com
|Let's Build the S.H.O. Drive! - Slide 050 of 176.png||'''Magnetic Rotor''' ''(Assembly)'' • 20 Large Neodymium magnets with dimensions of 3/2” x 3/4” x 1/2” (or about 38mm x 19mm x 13mm) will be stacked like Jenga blocks to form the rotor. • 8 Small Neodymium magnets with dimensions of 3/4” x 1/4” x 1/2” (or about 19mm x 6mm x 13mm) will be stacked in between the large Neodymium magnets. • Together these will form a flush fit around the 3/2”x1”x1” (or about 38mm x 25mm x 25mm) square nut assembly, resulting in a magnetic rotor assembly measuring 6” (or about 150mm) long with square poles faces measuring 3/2” (or 38mm) a side.

|Let's Build the S.H.O. Drive! - Slide 051 of 176.png||'''Wood Panels''' ''(Disassembly)'' • I will unscrew the hinges off of the wood panels, enabling insertion of the shaft and bearings into the panel holes.
|Let's Build the S.H.O. Drive! - Slide 052 of 176.png||'''Bearings''' ''(Phase 2 Parts)'' • I ordered shielded ball bearings from VXB at Amazon.com. These bearings are rated as having electric motor quality and will carry the weight of the shaft. • These bearings should fit snuggly into the holes carved into the wood panels.
|Let's Build the S.H.O. Drive! - Slide 053 of 176.png||'''Inserting the Rotor''' ''(Assembly)'' • After that, I will insert the rotor assembly, through the installed bearings. • Then I will fasten the wood panels back onto to the base blocks.
