Bill of Materials
List is in process of being completed. Whichever
engineer is the first to be able to visit Mann should document all of these
specs.

Part list for Unit 0 reproduction
Gear Set for : Unit 0
I have no part number yet, but here are the sizes.
Small gears
- number small gears 2
- 24 diametric pitch
- 80 teeth
- pitch diameter 3.3333
- .187" wide + or - OK But to wide will have more drag.
- hub/ ½" bore with key way & ss or some fixing system
- carbon steel
large gear
- 24 diametric pitch
- 160 teeth
- pitch diameter 6.6666
- .187" wide
- carbon steel
- hub/ ½ " bore with key way & ss or some fixing
system
Shafts
- stock McMaster-Carr part number 89325K25
- There are 3 shafts ½" diameter 23 3/4" long with
standard key way on the gear ends
- non-magnetic 316 stainless steel.
Bearings
- There are 6 ball bearing all being the same size, but having
some differences noted below.
- Three of the ball bearings are McMaster-Carr part number
6383K41 open; this was done to lower drag. These three bearing
that are used on the gear side of the motor away from the
magnetic fields.
- The three 304 stainless steel ball bearing McMaster-Carr part
number 5908K17 open.
- These were used on the magnetic rotor side to help reduce
possible magnetic hanging.
There are three Bronze Sleeve used as spacers.
McMaster-Carr part number 6391K124.
These are used between the gears the bearings , and may or may
not, be cut down to set the shafts in play lash. They will go
through a hole in the end support plate to push on the inter bearing
race .
There are six one piece clamp-on Collars used to set the
shafts in play .
Three that are used on the gear side McMaster-Carr part number
6435K14 steel.
Three that are used on the magnetic rotor side are part number
6435K34 303 non magnetic stainless steel
The Base Plate is1 inch thick by 12 inch wide and 24 inch
long. The end support plates are 14 inch a part center to center. On
the end that the magnetic rotors are to be places; the first end
support plat is 6 ½ inch back from the end of the base plate to the
center of the end support plate.
The Both End Plates are the same. The bearings are counter
sunk into the end plates, so that they are flat with the insides.
The through hole that shaft goes through is sized so that the bronze
sleeve does not rub. The counter sunk are place to the inside then
the clamp-on collars keep the shafts in play to .001 The end plates
are 12" by 6 ½" by 1".The shafts are 5" on
center and 5 ½" from the base plate. The end plated are fixed
in place to the base plate with 4 SS bolts each. |

RE: Bill of Materials for an exact replication
In order to replicate Douglas A. Mann's system exactly, the unspecified details
are needed.
Ideally, the exact mfgr part and batch numbers should be specified. Here's what
I got from the website, please correct as indicated, and make as comprehensive
as possible:
List
- Qty 16 (get extra), Neo magnets, Ni-plated N32 cylindrical, 3/8 inch
diameter by 1.75 inch long. Polarity: poles on ends.
- Qty 1 (get extra), Neo magnet, Ni-plated N32 rectangular, 1/2" x
3/8" x 1 3/8. Polarity is on the flat side, with the 1/2"
dimension face holding the N-S polarity.
- Qty 1, rectangular Delron sheet .5" thick, length x width
unspecified.
Serves as support base of system.
- Qty 2, rectangular Delron sheet .5" thick, length x width
unspecified.
Serves as vertical shaft support pair.
- Qty 1, 8" disc, cut from a Delron sheet .5" thick
Serves as main rotor.
- Qty 2, 4" disc, cut from a Delron sheet .5" thick
Serves as side rotors.
- Qty 1, piece cut from a Delron sheet .5" thick? length x width
unspecified.
Serves as Actuator magnet Holder.
- Qty 3, #3-16 stainless steel rod .5" dia., lengths unspecified.
Serves as rotor shafts.
- Qty 1, steel gears, unspecified pitch, style, diameter, thickness,
weight, hardness.
Serves as main rotor gear.
- Qty 2, steel gears, unspecified pitch, style, diameter, thickness,
weight, hardness.
Serves as side rotor gears.
- Qty 6, ball bearings, .5" ID. Unspecified rating.
Serves as side and main rotor shaft bearings.
- Qty, pitch/length sizes and material unspecified, Screws.
Placements unspecified. Serves as device to affix Delron
structural supports together.
