This is a dangerous machine, and is perfectly capable of causing serious injury. For this reason, you must be trained to use it. It's fitted with a and ACNode and a key-switch emergency stop so that only keyholders can switch it on.
It's worth reading around the subject before you try to start on the actual machine - it's easy to teach some simple basic operation, but much harder to teach all the things you SHOULDN'T do. You've got to get a real sense of your limitations, and always research any new operation to make sure you're doing it safely. There are pointers to educational materials in the Library
For full information and to sign up to training sessions, see the Lathe Training page
MIT have 3 videos about working with a lathe. You will still need in-person training, but they are full of good tips and will help everything go smoothly.
- Lathe 1: Lathe basics; turning and facing; cutting off a part
- Lathe 2: Tapping; boring; knurling; cutting tapers; turning shafts with a live centre; single point thread turning
- Lathe 3: Chucking large items; using lathe arbours; turning between centres; working with irregular shapes & thin materials.
Using the 3-in-1 Lathe
The Logbook is used to record any changes, problems or concerns about the machine.
Oiling is critical to keeping the 3-in-1 in a good condition. The machine must be oiled before and after every use. The slideways should be oiled with slideway oil, and all other parts should be oiled with general-purpose machine oil. See the full manual for further details: File:Centurion Instruction Manual.pdf
- 10-JUL-2014 (James): I spent a fair chunk of time making a new micro switch aluminium shaft & chuck guard for the 3 in 1. Now it lets you open the chuck jaws to their full potential with ample clearance from the edge of the Perspex. I designed it so it stays horizontal relative to the chuck and will not operate if the chuck key is located in the chuck.
A basic set of tooling is already available:
- 125mm 3-Jaw Chuck
- 1-13mm Drill Chuck & Arbor
- MT4 & MT3 Steel centres
- Lathe Tool Set
- Milling Drawbar
- 4-Way Indexing Toolpost
- Combined Vice/Compound Slide
- Lathe & Drill Chuck Guards
If you would like to help there is an active pledge to buy more tools for this machine.
It is recommended that you supply your own cutting tools, e.g. 12mm shank tools. It's generally not recommended to grind your own cutting tools unless you really know what you're doing (and have the time!)
