you do deserve a cheer. Great job..  ! question , how do you have the sled set up -- the attachment to the dride shaft//??

Not sure what your asking but the sled rides on the 2   1" round bars and is driven by the rear motor on a threaded rod if that helps.  Holes are drilled through the sled frame to accommodate the 1" rods  The threaded rod slips through holes in the center of the sled and there is a threaded catch and release attached to the sled. When in use the release is spring loaded to hole tension on to the threaded rod to screw the sled in motion. There is a lever to separate the two halves of the release so the sled can be moved back and forth by hand when needed
