Subject: Need Basic Lathe Info

Hello,

I am a scale model builder and I have found myself wanting to lathe and
mill pieces for scratchbuild projects.  So I know very little about the
mysterious world you all are familiar with.

If you have a moment could you please tell me some basic
terminology/ideas.  Or if you can reccommend a good starting book, that
would help too, but your answers would be best.

Thankyou!  Here are the things I don't get...

What is the basic concept for creating "steps" and "gears"

headstock/tailstock?

"Swing over bed"/"Swing over carriage"

fly cutter?

dividing attachment?

collet?

Thanks!
-Robert

OK, since I have the right name for the Lathe questions, I'll tackle
some of those. But PLEASE listen to others too.

Headstock is the assembly on a lathe, usually on the left hand end, with
the power.  A chuck, faceplate, or collet (see below) is mounted to the
spindle (the shaft running through the headstock) and the workpiece is
mounted to or in that.

Tailstock is generally on the right hand end, and has a tapered hole
which can hold a drill chuck for drilling into the workpiece, or a
center to support the weight of the end of the workpiece while turning.

Swing is the DIAMETER which, when mounted on the spindle, will clear the
bedways.  This is usually pretty close to twice the height from the
bedway to the spindle centerline.  Swing over cross slide is the same,
but to clear the slide.  This is usually the largest diameter that you
can turn a length of material.

Collets are either workholders (for Lathe use) or toolholders (for mill
use), although there are exceptions.  These generally are steel devices
which, when drawn into a tapered seat will collapse and grip the part or
tool.  Generally very accurate, gentle but firm grip due to full
circumference grip.  Draw back is a very limited range per collet,
perhaps only a few thousandths of an inch.

Next!
