I started the creation of a chock mount that mounts on e track running length wise. I could not find a solution that made me happy so I created another one that I am not happy with That said I plan on the next being improved and the design and knowledge might help others, so here it is. The design consists of a Pit Bull chock mounted on red oak with a iron bar attached to the oak and etrack clips. The problem with the design is that the fit is to tight, when attaching the platform holds the clips to high. To mount to etrack you need to attach the bar then bolt on the red oak platform. One design I am considering for the next is to fasten the clips to the bar with a 1/2 bolt interface so that the clips can rotate.
