History

The Myford super 7 lathe arrived at Nottingham hackspace in November 2011 thanks in part to members pledges.
The Myford company started in 1934, was based here in Nottingham (Beston to be exact) and only closed it doors due to liquidation back in July 2011. The ML7 lathe was launched in August 1946, retailing at £34.00 excluding motor. Later replaced by the the Super 7 in April 1953 build around the same design but with number of new features and improvements. Both models have been very successful and often favoured by hobbyists and model engineers.

The Hackspaces Super 7 has been dated to around January 1973.

Safety

DO NOT OPERATE THE LATHE UNTILL YOU HAVE BEEN INDUCTED, see below for details.
As always at the Hackspace YOU are responsible for your own safety, proper machine operation and safety of those around you.

Borrowed most of the following from Mini-lathe.com & lathes.co.uk --'RepRap' Matt

  • Always wear eye protection
  • Wear short sleeve shirts, if possible, or shirts with snugly fitting cuffs if long sleeve
    • Loose sleeves can catch on rotating work and quickly pull your hand or arm into harm's way. 'RepRap' Matt has the scar to prove this point!
  • Remove wrist watches, necklaces, chains and other jewellery
  • Tie back long hair so it can't get caught in the rotating work
  • Never, ever, leave a chuck key in a chuck.
    • Get in the habit of removing the chuck key immediately after use
    • Never remove your hand from the chuck key when it is in the chuck
  • Keep your fingers clear of the rotating work and cutting tools
  • Avoid reaching over the spinning chuck
    • Please do not use hand held tools or files on this machine with the spindle switched on. See below for use of emery cloth
  • After setting up any turning job, take a moment to pull the job round by hand to check that everything clears

Polishing/use of emery cloth

The use of emery cloth for polishing is common practice, but carries a high risk to both machine and operator.

  • HAND HELP EMERY CLOTH MUST NEVER BE USED Please see this link for the HSE recommended method of holding emery tape in a tool holder: https://www.hse.gov.uk/engineering/lathes.htm
  • The abrasive dust will mix with any oils and form a grinding paste, which will ruin the slideways. Please clean all slideways thoroughly before AND after polishing.

Lubrication

You should always lubricate the Myford Lathe before use.

Here is a handy chart to show where to lubricate. File:Myford Lubrication.pdf

Note the modern equivalent of Esso Nuto H44 is 32 weight Hydraulic Oil (H32). Also note the "nipples" are for oil not grease!


Inductions

See also: Myford Lathe Inductions

All members are welcome to undertake a lathe induction, the induction is there to instruct you in the safe usage of the lathe. It will also give you the skills needed to do most of the basic lathe operations.
Induction cost £20, to cover cost of materials and lathe maintenance and some to the inductor.

Refresher Video

This helpful video gives an overview of the features on the Myford Lathe. It does not act as a replacement for the induction but is a useful tool for jogging your memory after you've had an induction.
