Rover wheel, floating pad

pinshape

Floating pad design for loose sandy terrain.      First design was to use Tread plate A & B alternate.  Using bungee cord through every other pad loop.   But as in first print.  I use only Tread Plate A.    Bungee cord through every pad loop in order.   Bungee cord used currently is  5 mm (3/16" ).     Alum. Tubing is aircraft 6061 T6   3/8".    Thickness will have to be determined by weight of Rover.    Tread plate holes/ pins are 1/8".   Rod End holes are 3/16".     Axle/ Spindle has 1/2" axle hole.  Also Spindle has 1/8" holes for locking in spoke tubes.  Can use Tread plates A in one wheel.  Tread plates B in the other side.   Alum. Tubing in test wheel was 4- 3/8" in length.    That is the minimum length.  Most certainly could have been a touch longer.   Current wheel size is :   ( w/ 4-3/8" tubes) =  About 12-1/2".    Future fixes will be longer spoke tubes.    Making mold for vulcanizing  rubberized tread pad.  Print Parts count per. wheel:      Spindle = 1    ,      Spoke tubes = 27   ,    Rod Ends = 27  ,   Action brackets = 54  ,   Tread plates = 18 Recommend :   Using thin washers between action parts.  Also  if planning on using screws.  Use fiber self lock nuts.  Thanks for Looking!
