Finishing up Battery Tray

The battery tray was re-installed today, and following the Airheads.org club canon #2, "Airheads believe that the simplest engineering solutions are the best." With this in mind I looked for the rubber vibration bobbins that connect the battery tray to the frame. These little dampeners cost $13-18 dollars a piece x 5 from BMW, so to spend $65 seemed a bit high, so I went forward with my solution.



Went to Ace Hardware and bought 5 rubber stoppers @ 43 cents a piece, cut them down to the dampener length, drilled a 1/4 hole through the center and proceeded to bolt them to the tray and frame using M6 metric bolts, washers and nuts. Overall the cost was less than $5 dollars, looks good, and holds the tray solid.



The original dampeners are rated to hold 25lbs a piece, and the rubber stoppers are rated around 22 lbs so this seems sound, proof is a year from now.
