Power X feed

[RedpiperbobParticipant @redpiperbob16487]

Hi All is it possible to modify a Myford Super 7 non powered  cross feed to a powered one.

Thanks Bob

Hi There

Yes, use a bolt on attachment.

One or two have been described in MEW.

Particularly Tony Jeffree’s CNC conversion and someone did a conversion of a mill feed using, I think, a stepper motor that was excellent and a similar system could be used.

If all you want is the power feed feature you don’t even need a stepper motor, just a small DC motor with a speed control would do. My late father was planning something like that for the Myford ML7 that I now have, and had mounted a platform at the back for the motor. Might tend to get in the way if you also want a taper turning attachment. With a stepper there would of course be other possibilities, given a smart enough computer attached.

I have modified my minilathe to provide a powered cross feed. I think this would be readily adaptable to other lathes. Details are here:

Hi Mike

How about an article for MEW?

How about lots of articles?

Mike, that’s a superb modification, I think I’ll be plagiarising it for my mini mill!!

Hi John,

Thanks for your kind words about my minilathe cross slide power feed. I have recently added a power feed to my X1L mill that may interest you. You can find it here:

Superb mod’s Mike, and so straightforward, many thanks for posting them up.

May well be worth your while talking to David Clark 1, I’m sure many users of these machines would appreciate the articles, particiularly those without internet access.

 

I broke up a couple of laser printers a while back, and saved all the motors, I’ll be having a root through them now to see what can be used.

I know some are steppers, but not sure about the others or what voltages they run.

As it happens, I’ve quite a bit of rectangular drain pipe going spare ;&gt)

Regards

    The system I use on my mill could be addapted to the lathe. It consists of an old Lucas windscreen wiper motor with the shaft through the worm wheel extended to take a 10 tooth sprocket. The micrometer sleeve on the l/h feed wheel is replaced by another with a 20 tooth sprocket, the the drive is by bike chain draped loosely over the sprockets (so that it can be easily lifted off for hand feeding).  POwer is supplied from my work shop low voltage supply at 17v through a three possition switch, giving three speeds via resistors, and a on off on switch gives foreward and reverse.  Its a bit rough but it works. If I was putting it on a lathe, I would extend the feed screw  on the top slide and hang the unit at the back of the bed.  An electronic control would be better, and it may need different gear ratio, the motor speed on mine is 120rpm flat out, and after an hour its starting to get a bit warm but not too bad.  Ian S C

Hi all

I dont know what happened to my reply last night, but heres goes again. Thank you all for your relpies and thank you Mike for the idea. I think that is the way to go.

Thanks once again
