I use a drill press like the first one in the linked answer at home for drilling my PCBs. If there was a way of sliding a PCB along a straight line left-to-right (or front-to-back) it would make drilling holes which are in a straight line much faster.
Do such slider systems exist without big costs? Or is there a design someone can share for making one? If there could be a system which also has ratchet-type stops every 0.1 inch, and which is equipped with a "latch" to switch between left-right and forward-back, that would really help.
