"If thy pride is sorely vexed when others disparage your offering, be
as lamb's wool is to cold rain and the Gore-tex of Odin's raiment
is to gullshit in the gale, for thy angst shall vex them not at
all. Yea, they shall scorn thee all the more. Rejoice in
sharing what you have to share without expectation of adoration,
knowing that sharing your treasure does not diminish your treasure
but enriches it."

Hmm ... what makes a tailstock 2-speed? Is it powered, or is
there some mechanism so it moves a greater distance per turn of the
wheel until it sees a load, and then drops to a higher mechanical
They are usually geared down, Most of the Lodge & Shipley lathes had a
two speed tailstock, a real arm saver when trying to punch a 3" drill
through a chunk of 4140 :-) I think the L&S I used was 5 to 1 ratio.
Normal was .250 a turn and slow was .050 per turn. With the smaller
drills or in aluminum it was almost like freewheeling through it in low
range :-) But at .050 a turn it took a lot of turns to go through 8
inches of metal.
I have a Leblond and an Axelson that have two speed tailstocks. On the
axelson you pull up a pin and pull the hand wheel out. On the Leblond
you pull a sleeve out that is located on the hand wheel. I have never
looked at what the ratio was but like James says, it sure is a lot
easier drilling with large drills.
