My drill press came with the laser device and although I don't use it all that much, I will be using it to drill the 52 holes in each of the 10 bases of those wine basket frames that I'm doing for my basket weaving friend. Not difficult at all to set up and in this case, where no height adjustments will be made, it's worthwhile. I'll also use a fence for distance "in" from the edge but the laser will help with the spacing between holes. It's a guide, if you don't like it, don't use it. Mine has a dial for x and a dial for y setting....I put a bit in the DP and set it about a 1/4" above the work piece and then set the laser(s) where the bit will make the hole....if it took more than a minute to do this I'd be surprised.
"It's just a hardened oz or two of metal, sharpened to a razor edge, spinning at 24,000 rpm.....what could go wrong?"
