You are making yourself look like a fool. Any idiot, which you obviously
are, could see why everyone should reply in the same fashion so posts
maintain a chronological order. Since the VAST MAJORITY of Usenet posters
bottom post, then logic says you should too.
Unless you are suggesting that the rest of the world should change for you?
I think you are just an inconsiderate jerk who doesn't care if your laziness
If you like being ignorant of proper usenet etiquette, there isn't much I
can do about that. At least I tried to educate you.
But even if you don't understand why you should post that way, out of
courtesy to others, you should conform to long standing protocol. You know,
the whole "When in Rome..." thing.
But pretending that YOU are right while 95% of the other people on usenet
are wrong, is somewhat pompous in my opinion.
You have to do what once per thread?
Bottom posting doesn't force you to scroll through every article, only
the text that has eben quoted by the current author. When I do that,
I glance through the text so that when I arrive at the new text I
understand the context.

It sounds like you're turning a long thin spindle. When the L/D gets
over about 15 the center of the spindle starts to whip (like a
jumprope--first dynamic mode of instability). to put more pressure
(until your live center turns at the same speed as the wood, as
previously mentioned) you will increase this vibration. To turn long
thin spindles like this you have to strike a happy medium by doing one
or more of the following, and it gets harder the longer your spindle
a. make it so the tailstock is slightly looser, but this isn't the best
choice, as your piece will then vibrate on the spindle cone and cause a
b. hold the spindle steady as you turn, either with your hand, as many
old style turners do, or using a steady rest. The steady rest takes a
lot more time, and it's often easier to use the hand that is at the tip
of the tool to kind of hold the piece steady as it spins. The way many
turners do this, they put their left thumb on the tool tip and the four
pads of fingers rest on the spinning spindle. This really is only
helpful and safe once the wood is close to round, or at least octagonal
with rounded corners from your first tool pass.
Roughing out the spindle can be made easier by starting with a straight
tool edge and scraping away a few mm at a time, making each cut round
before you take off the next few mm. Trying to use a cutting action
with a nonround part is going to take longer and be more frustrating
when you're just beginning.
c. I have had great success turning long spindles (L/D>30) with a
short, very low angle hand plane held in one hand and the second hand
on the opposite side of the spindle, holding only the flat of my hand.
Again, you should start with a scraper to make the whole thing round
before you try cutting with a plane, and use the plane only to make it
smooth and cut a fair, straight line. Using a plane, press the shoe
flat against the cylinder to be cut, blade edge perpendicular to the
axis of rotation so it's not cutting and slowly change the angle of the
plane until it just takes off the smallest finest curl of wood, and
then be patient. I find the best angle is around 20-45 degrees from
perpendicular. Take many passes like this and you can get a glassy
smooth finish as good as a skew or better, but with less vibration
because the piece is supported.
When I use a hand plane for long spindles, I don't use a tool rest. It
seems like it will help you support the plane, but I think it adds a
high risk of seriously pinching fingers between the wood and the tool
Leo's answer is correct on this. More info: some lathes have
adjustments for that problem. Mine only has a side to side adjustment,
so if they're off up and down, I have to shim the headstock until
they're the same height.
Less than a mm, you'll never notice the diff unless you're turning with
a geared & indexed tool rest. If I get it under 1/8" (2-3 mm) I'm happy.
Ya just gotta love that any and all part... :-) Kinda like the part of
my job description that says "and other duties as assigned"...
Ah the faithful and the flighty you get em all on here. One of my
favorites is the on going battle of Top post/bottom post... Just a bit
more entertaining than the Church of "I hate Crapsman"....
But enough of that... I'm a lathe dabbler myself and I've learned thru
trial and error and input from here and other sources. Any time you
pick up a new tool it does help to seek advice from somebody who's done
it. The posts above cover anything I could share from my limited book
One thing I'll rehash is the face shield (and you may already have one
and use it faithfully) but we can never cover safety enough. That and
loose shirts or hair. I was wearing a long sleeve shirt one winter day
with the cuffs open and loose while working on the lathe. Let's just
say it was almost an educational experience.
Have fun, try different stuff, and don't be afraid to ask for help on
the rec... You just have to ignore the crankier ones occasionally...
