Today was a play day in the shop (Code Name - Chaos) and needed to drill many 5 mm holes in a straight line at fixed intervals (2 inch on one project and 3/4 on another). Here is how I did it using a guiderail, the Festool 5mm router bit and some other accessories I already had.
Drew a straight line and marked starting hole location. Inserted router bit and set depth, etc. Set guide rail and adjusted router center marks to the line and also the starting hole. Installed two limit stops on either side of the guide stop. Drilled first hole. Loosened one limit stop and slid router assembly to allow block(cut to interval distance) to be temporarily inserted. Tightened loose limit stop. Removed block and moved other limit stop. Drill and repeat.
Not the fastest approach, but accurate and used things I already had on hand.
