Sorry no plans or dimensions. I do projects like this by starting out with templates and mock ups. The templates are usually poster board. I then use them as patterns for the final product. I also use transfer pins for fastener location centers.
The only way to draw up dimensioned plans would be for me to disassemble them then measure everything. If that were done, I am certain there would be some strange measurements.
It is not unusual to find, after fabrication, that a part does not fit as intended. Several of the detail parts were made and redesigned more than once. Insert "doh! here.
The objective in showing the sliders was to provide motivation for someone else to use them as impetus to design their own set. I know that there were a few things that could have been done differently.
I had one design objective, other than the obvious, and that was to place the pucks centered and below the swoosh. I had two constraints. I wanted to use materials (6061 T6) I had on hand, and I wanted quality 12.9 fasteners. Anything stronger would have not provided the necessary energy absorption prior to yield. Anything weaker would have been futile.
Example of poster board templates for part location.
Transfer pins for copying fastener locations. A couple of the bar spacers are examples of mistakes because I had to redo them a few MMs longer.
Fit check. Notice the plate and one side of the bar are not chamfered nor finished, and the bar end is not to length, radiused, or counterbored yet. I only do the work necessary for a fit check. Then, if it passes, I continue with follow on processes. You learn to be that way when you are lazy.
