Various pictures of the lathe.
Initially, nearly all the parts of this lathe were nothing more than scrap! Each part was acquired separately and carefully restored. The lathe bed has been reground, the saddle has been re-machined and slide-ways scraped etc. The bronze spindle bearing has also been carefully scraped in to maximise performance. It can now out-perform many lathes of this capacity by adding the CNC kit. The motor is a TECO 1HP 3 phase, powered by a TECO variable frequency inverter. Both items can be purchased from Drives Direct.
In 2018, a TECO 2HP 3 phase motor has been added which really makes a massive difference to the performance when machining larger diameter components. There is also improved speed stability when screw-cutting without having to engage back-gear.
A simple homemade 3 Axis stepper motor controller for the lathe which uses the most basic of breakout boards for the parallel port. (top left in photo) The third axis is intended for a tool changer which would be a nice feature to add in the future………….!
An afternoons ‘playtime’ at the Doncaster International Model Engineering Show produces plenty of swarf…….and some shapes that would be virtually impossible to make on a conventional Myford Super 7 without resorting to filing.
A potential buyer looks on as a 10 start thread is machined. (one of many being machined over the weekend)
There was fantastic support and interest in the CNC conversion at the Doncaster Show, proof that there is a healthy and rapidly growing trend towards high tech CNC home workshops.
Thank you to all who made comments and kind remarks about how the lathe looks and operates.
