== Level-1 induction ==
This is the most basic induction and provides only the absolute essentials.
{| class="wikitable"
Line 83:
* Approximate truing and even tightening
* The 3-jaw is not accurately concentric, so don't take workpiece out till you're finished
* '''Not leaving the key in the chuck!''' This is the most common source of accidents on lathes and can cause serious injury
||
Holding the work securely but only on a basic level for induction.
Line 96:
|The Lamp ||
* Positioning the mag-base lamp properly, taking care that it won't foul over the full range of motion intended. Beware of stroboscopic effects.

Getting a clear view, and not being fooled by strobe effect
Line 610 ⟶ 609:
* Using reamers
* Turning between centres
** Why you might do it
*** Improved concentrically and repeatability
*** Holding awkward shapes
*** Reusing centers on existing parts or that someone else cut
**** Recutting a center if you need to (toolpost support trick)
** Setting up a center and a catch plate
*** Installing a center in the headstock
*** Installing the catch plate
*** Picking a suitable dog size, setting it up so it won't slap
**** Caution about over or undertightening
*** Alternatively making a center on stock held in a 3/4 jaw chuck
*** Live or Dead center at the tailstock?
*** Might require the use of steadies if the part is long
** Turning between centers
*** The dog and catch plate will cause imbalance so watch speed
*** Parts may be very long so watch out for flex
**** Use support if needed
**** Take shallow cuts
** Tailstock offset turning
*** Regular centers only for the smallest of offsets
*** Using ball-bearing centers▼
**** Part distortion if used too much
▲*** Using ball-bearing centers for larger offsets
*** Resetting the tailstock alignment when done, high precision required
* Making and shaping brazed carbide cutters
