Sorry for the delay . Was sidetracked working on other elements of my display. My pixels arrived today so I made some final adjustments bought a small drill press and set it up tonight. Was going to use a step drill but found the small press doesnt have enough travel. So going to either get a new 12mm drill bit tomorrow or look at some other options to get a more precise hole. But took a couple of pics of the rig anyway.shoot some pics of the drilling
Fairly simple idea it consists of a drill press vice, a spare bit of steel plate and a 12mm bolt with its head removed .

Once the first hole is drilled, it is moved onto the pin, then every other hole will be in perfect alignment.
