I have a few questions concerning the usage of axle set collars.
Our design is a scissor lift and calls for a large amount of shaft collars to hold the cross members in place. (Somewhere around 216)
The first question is may we use vex set shaft collars? It isn't the right size for
the Tetrix axles, but if we bore out the center to accommodate a Tetrix axle, would this be legal? I've been seeing that vex fasteners are permitted, so would a modified shaft collar be considered a fastener?
The second question is if we do order set screw shaft collars from a supplier such as McMaster-Carr, what Bore would we need? I'm guessing at 1/8".
Answers would be much appreciated.
I decided I would keep coming and it just kept getting more and more fun. By the time build season started going I couldn't have quit if I wanted to ^_^ - Mr. Pockets [more]
