UPDATE

PLEASE PASS THIS ON TO THE MECHANICAL SUBTEAMS

Key ITEMS

• 27.25” LONG x 37.25” WIDE
• Rear wheel axis at 5.625 from most rear surfaces (adjustable down to 4.625 corner brace regime permitting)
• Front wheel axis at 11.625 from front most surfaces (adjustable ± 2.00”)
  

• Still need to determine a few hardware items but I think we could use a few PEM fasteners to further minimize fastener system weight
• We will need to design a few spacers “on the fly” as we determine the best approach while building
• The 6-hole patterns in the wheels need to be tapped for 10-32 Depth TBD
• Need to add the stiffener element between the wheels (1/side 1”x1” ext. Al stock is light and will work well and can be welded)
• Need to cut necessary smaller frame elements from stock
• Need to design in provisions for front “dummy wheels” biased 1/8” up for roll over protection
  

• Need to order the following parts from the shop by tomorrow:
• 2009-wheel-hub (1/8 wheel retainer plate) QTY:4
• Hub-bearing (just a spacer in the hub for support not a bearing) QTY:4
• Brkt-wheel-asy-1 (trans/motor mount left front and right rear) QTY:2
• Brkt-wheel-asy-2 (trans/motor mount left rear and right front) QTY:2
• Bearing-block (main double bearing holder for each drive assembly) QTY:4
