The Myford ML 7 is on loan on a (hopefully) permanent basis from Steve. As such, treat the machine with respect and do not abuse/mistreat it.
The Myford ML 7 lathe was manufactured in the 1940's as a light machining and model lathe. The lathe has the space to take a roughly 5" diameter by 20" length piece of work (double check actual sizes).
This machine is ONLY for metalwork, and should only be used by people who have been trained.
- When first starting to use the lathe, the oil containers on top need to be turned a quarter turn to undo them to let the oil start to flow. These need to be closed off after you have finished using the lathe
- There are 13 points that need to be oiled (16 on the diagram), place the can with a black tip of the metal bottle onto each point with a single squeeze to force oil into these points

Please follow these safety precautions when using this machine, and again, DO NOT operate this machine if you have not been trained, or do not feel confident with it.
- Always ensure someone else is in the space when using the lathe
- Always wear Eye Protection
- Swarf can be very sharp, and the last place you want it is in your eye.
- Do not wear loose fitting clothes, especially anything with long loose sleeves. Short sleeve shirts/t-shirts are recommended.
- Even though this is a small Lathe, this machine still has enough power to break you.
- Do not wear jewellery which could get caught in the machine. This includes bracelets, necklaces, watches etc.
- Tie back long hair to keep it away from the work
- NEVER LEAVE THE CHUCK KEY IN THE CHUCK
- The chuck key has a home on the little metal plinth in front of the gear housing. Get in the habit of the chuck key being there when not in use.
- Keep fingers clear of a moving chuck and workpiece
- Never reach over a moving chuck
- Make sure that the work piece will not foul on any part of the lathe when turned on - always spin the chuck by hand before starting the machine
There will probably be more to come over time, but these are some main ones. Obviously, do not be an idiot, and think about what you are doing first.
- Ensure the oilers are kept topped up, and opened when the lathe is in use
- Oil all oiling points regularly - see the diagram on the right.
Inductions are now available - please contact Greg Morris ([email protected]) with the following information:
- What times you are available for training
- What previous experience you have using a lathe
- Any particular skills you want to learn
Basic lathe training has a £2 cost - this is to cover the cost of the materials that are provided. It consists of making a standard product (a 2-part plumb-bob) out of aluminium and acetal.
This training covers the following skills
- Health and Safety
- Using the 3-jaw chuck
- Facing and turning to diameter
- Taper turning
- Threading with a tap and die
- Grooving and parting off
Other skills will be taught upon request - this can either be on material supplied by the trainee (a project, for example), or the material can be supplied by the space for a small fee.

Guide to the risk matrix points system
|Hazard severity||Points rating||Definition|
|Nil||1||Very minor injury, bruise, graze, no risk of disease.|
|Slight||2||Minor injury, which would allow the individual to continue work after first aid treatment on site or at a local surgery. The duration of the stoppage or treatment is such that the normal flow of work is not seriously interrupted.|
|Moderate||3||Temporary disability causing injury or disease capable of keeping an individual off work for three days or more and reportable under RIDDOR|
|High||4||Causing death, serious injury or permanent disability to an individual.|
|Very high||5||Causing multiple deaths and widespread destruction eg. fire, building collapse.|
|Hazard probability||Points Rating||Definition|
|Remote possibility||1||There is really no risk present. Only under freak conditions could there be any possibility of an accident or illness. All reasonable precautions have been taken - This should be the normal state of the workplace.|
|Unlikely||2||This incident or illness might occur but the probability is low and the risk minimal.|
|Possible||3||The accident may occur if additional factors precipitate it, but it is unlikely to happen without them.|
|Highly likely||4||Will happen more often than not. Additional factors could precipitate an incident but it is still likely to happen without this additional factor.|
|Inevitable||5||If the work continues as it is, there is almost 100% certainty that an accident will happen, for example:
• A broken stair or broken rung on a ladder • Bare, exposed electrical conductors • Unstable stacks of heavy boxes
|Risk Rating Definitions|
|1 to 4||Low||No action required|
|5 to 9||Moderate||Reduce risks if reasonably practicable|
|10 to 15||High Risk||Priority action to be undertaken|
|16 to 25||Unacceptable||Action must be taken IMMEDIATELY|
|1 Nil||2 Slight||3 Moderate||4 High||5 Very High|
|4 Highly Likely||L||M||H||U||U|
