I like the plywood mock up idea!
Cheer's, Neil.

The operator did stop....for a second or so...LOL...and then he drove them over (that was the most exciting part in the video...LOL )

The plywood profiles are very handy...and easy to cut on the table...it also helps keep my kids from asking me when they can see something other than a drawing...LOL...

Cut some test sprockets.....didn't buy the right ones so I made some to test the drive and speed (.250 Pitch )

First try using this type of steering control ( this one did not work needed some changes )

Used a Hitec 785 winch servo ( 3.5 turns) and a 12T sprocket ( servo city)

Needed to get this thing on all fours...or should I say six....
Cut the bearing hubs off the cheap rims that came with the tires , then made simple front hubs for testing this thing out...after welding they got faced off , drilled and reamed for some bushing. I hope to make some better front hubs with ball bearings later on (but most likely I will use these for a long time..LOL)
