Line 4: <div id="level1"></div> == Level-1 induction == This is the most basic induction and provides only the absolute essentials. This is the most basic induction and provides only the absolute essentials. With the new card-based access control system coming soon then we may have a lot of people who suddenly need induction despite being already familiar with lathe work. That means this induction needs to be short enough we can do it quickly and in bulk cause we don't want people getting pissed off and skipping it or trying to bypass the control system. This plan for induction is fairly stable now and all trainers should be working from this plan, suggestions for improvements are still welcomed though! {\| 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 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
