Are there other ways to build punchers rather than building them with slide rails?
I saw this video of a linear puncher from NBN that utilizes sprockets and chains as a substitute for the slide rails. The sprocket acts as a replacement for the gear and the chain acts as a replacement for a rack( in a rack and pinion).

@293X I have a(n) improved Puncher
Looks like the one I built 
@RunsWithScissors IT WAS SHUO’S (I thought…)
I’m working on a puncher that uses pillow blocks and shafts instead of linear slides…it’s mostly used to reduce friction and take up less space
I had to rebuild what he had built so… not exactly. I built it.

i was thinking about a puncher design and i don’t know what to do?
