Aligning the holes actually wasn’t that difficult. I printed the pattern for the holes on a large format printer and then laid the pattern on top of the sign. I used a small punch to mark the center of each hole and then took the pattern off and drilled the holes. I used a drill guide to make sure I held the drill straight while drilling (link below). It wasn’t difficult, just very, very time consuming. Yea, there’s a fair amount invested in the LOR CCPs. Drill Guide http://www.homedepot.com/p/General-Tools-Drill-Guide-and-Chuck-36-37/100349264
