"mount the thread tap in the drill press and the work material in you machine vice (I assume you already have the hole drilled)"
...Love the title of this thread, it assumes you have a workshop and proper power tools at hand. If not the usual bog-std rules apply -e.g. take the tap or die and hold it as perpendicular as you can, apply a bead of cutting oil, feel for the first cut which will probably want to skew, correct to hold it perpendicular again, apply a small bead of cutting oil, make a half turn or so, turn back 1/4 for first 2 or 3 turns, for every turn afterwards make sure you take at least a half turn backwards. Once you get past 5 turns or so into the thread, unscrew at least half way back,aply fresh cutting oil etc. You should observe thread cutting tools, use them appropriately. I've not much had use of bottoming taps but used the few grades before.
....Not so easy if you don't have a lathe or press but perfectly do-able without! You don't need a lathe, drill press or anything to do it. -it does help though!
