do I need a new feed nut , and can you get just a feed nut as only seen with metric with a feed screw , one on mine is the old grey type not brass .. or is there any other adjustment I can try or tricks etc many help most appreciated Thanks Feed screw & nut for power cross feed are sold as a matched pair. I converted my S7 PXF from metric to imperial and the new components supplied by Myford and changed three times suffered from tight spots and I will convert back to metric as the feed screw and nut were perfect and I now have fitted DRO.

The gearbox/reduction unit resembles B&D drills of the early to mid 1970's and perhaps parts can be salvaged from an electrically destroyed donor. Robert Butler |

One of my old magazines has a photo of a Myford built into a home-made cabinet like a writing desk, where the top and front panel hinge open to reveal the lathe and form a small bench. Drawers underneath, I think Hollowpoint's Bisleys would be better. Unlike a real writing desk, the frame was heavy timber, probably 2x4, to keep it rigid, and it may have been bolted to the wall. Probably an image of Herbert Austins workshop in his bedroom at Lickey Grange. Robert Butler |

Steve can probably move this in one peice. If necessary you can partially strip when you get it to the workshop if not Bingo! Robert Butler |

Powered Z axis anybody? Obviously with the machine switched off!! it renders the third hand redundant and damage to dropped cutter eliminated. Robert Butler. Edited By Robert Butler on 02/05/2023 17:52:25 |

Wind the Z axis up or down in order that the collet with cutter loosley in place contacts the vice/workpeice and when cutter is in the desired position - tighten. Robert Butler

Jason, I've read somewhere it is to avoid a component which sits on a flat surface from rocking. I also recall that the amount was miniscule and definately with reference to Myford only. Robert Butler |

Hello again Robert, There is another mounting point where a collet closure can be attached just to the rear of the spindle that you may be able to utilize in some way to add a further choice to the mix. And finally from me, needing some ingenuity, a bar mounted off the X slide itself that can include a drop/swing down tab to butt up to the inner edge of the rear shear at the critical time End of ideas now! Brian Thank you once again

Robert Tubal Cain described a screw cutting depth stop that might adaptable to your needs. Basically it comprises a slide bar fitted to the top of the saddle using a hole provided for the travelling steady and a a fine adjustment screw carried in a suitably stiff plate trapped between the cross slide and the feed screw bracket. As described the slide bar is about 6 3/4" inches long with a near 2" slot for adjustment. The bar is 3/4" x 3/16" material with a piece 1/2" equal angle brazed to the outside end for the adjustment screw to contact. A second piece of 3/16" sheet 15/16" wide is used for the plate that is trapped between the cross slide and feed screw bracket to carry the fine setting screw. The fine setting screw is 1/4" x 40 TPI (ME thread) running in a boss almost 3/4" long brazed to the carrier plate. Tubal Cain uses a grooved head on the adjusting screw with a flat spring steel "click" device fixed to a 4 BA screw. My reference is Simple Workshop device published by Argus, also available as No 28 in Workshop Practice series, but no doubt it can also be found in Model Engineer and elsewhere. Clive Edited By Clive Foster on 24/04/2023 19:00:04 Clive thank you. I must be losing the plot, I have WP 28, looked it out and found a page marker showing TC's device which of course I had promptly forgotten all about!! This looks promising. Any other suggestions however gratefully received. Robert Butler

For 100 parts, I'd be adding a folding contraption to position the stock in the spindle too. A few bit of angle welded together, with M6 bolts for fine adjustment would be my starting point. Nick, the form tool is positioned agaist the material left after parting off so no issues with positioning. I am chasing material towards the headstock as the material will not pass through otherwise the cut off slide I have would be ideal. Thank you Robert Edited By Robert Butler on 24/04/2023 22:23:15 |

Don’t really understand why you need a solid stop when you have readouts on cross slide but if you must have one there is a hole for clamping travelling steady down to and a couple of tee slots on the cross slide, surely you can cobble up a stop to suit. Thank you Baz, I wan't to set everything up using stops for ease and speed as I have with Tailstock Turret. Other posts build on your suggestion to use the travel steady mounting point. Thank you again. Robert
