I didn't know this existed. I also made a drill mod the other day as I wasn't satisfied with the other options and wanted something simple, 1x1 and like the IC2 drills of old. It's just 2 tiers atm (iron/diamond, third tier isn't craftable yet and is yet to be decided in how it should be crafted and how special it should be). If you're interested, it's available here: http://minecraft.curseforge.com/mc-mods/233477-drillify
^this And emphasis on "estimated" SK currently has to rewrite systems, as outlined here. Other than that just a few more mods need to be tested. The worlds already pre-genned, spawn build has started (or so I hear), etc.
