Drivetrain-1.07.2009

Start time: 6:00 pm

End time: 9:00 pm

Members present: Tony, Goodman, Gannon, Larry, Dora

New bearings p/n r1212zz ordered.

Tony and Matthieu were show drive wheel asembly.

ordered transmission

built up chassis frame

Tasks to complete: '

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
