I'm glad that that helped, at least. :-0
O.K. That is what I was calling a "tapping stand", and I have no experience with them -- I've just seen them advertised in catalogs.
They sound reasonable for a few holes at a time, as long as the hole is perpendicular to the back surface of the workpiece (so it can rest on the table in the proper orientation), but beyond that, I would go for the tapping head instead. I believe that neither cost me more than $100.00, and I think that the larger one was something like $50.00
-- but that involved a bit of luck, too. :-)
Note that the tapping heads which I have I have fitted to MT-2 shanks so they both can go directly into the spindle of my drill press, without the additional length of a drill chuck forcing cranking the table down a bit more. As it is, there is a pretty good chance that the drill in the chuck and the tap in the tapping head will work out close enough to the same length so I can use the same table position for both.
I typically drill all of the holes, then switch to the tapping head, and if I am not dealing with blind holes, or thick stock, I'll often feed by hand with no stops, just noting when to reverse my feed well before the tap bottoms out of threads on the workpiece. If I need to use nearly the full length of the tap, or have to worry about blind holes, I will take the time to set the spindle stop carefully, and to take account of the dog clutch travel, I will pull the tap down and rotate it about 1/2 turn so it is resting on the ends of the dog clutch at the maximum travel point before it is deprived of drive. Then, when I get deep enough, I hear a "thunk", "thunk" ... as the dog clutch is just missing, and know to reverse the feed (lift the spindle) to switch the tapping head into reverse and let the tap be backed out of the newly-threaded hole. (FWIW, the reverse speed is faster than the tapping speed. The latter matches the RPM of the drill press.
Oh yes -- use a good tapping lube when doing this, unless you are cutting brass. The one which I most often reach for is Molly-Dee, though the Rigid pipe threading oil from Home Depot will work well for mild steel, and the original TapMagic is better for some tough steels. (And a *very* bad idea for aluminum. :-)
Enjoy, DoN.
