![]() ![]() ![]() From memory, they are a 10tpi screw so your 100 graduation dial will give 1 thou per graduation with this screw.Ĭhange gear charts for screwcutting are readily available online or in the books Norman Goldstar mentioned above. ![]() New imperial cross slide screw and nut are avialable from Myford in the UK at or their eBay UK store. It may be that your lathe has had a metric cross slide screw and nut fitted but kept the old imperial dial for some reason? (Myford supplied both imperial and metric screws and nuts and dials, so who knows what a previous owner did.) ![]() If one turn of the cross slide screw advances the tool by. One thing that I would go for is their rear parting tool kit- ex Volume 142 in Model Engineer or MEWM. Hemingwaykits are still flogging kits for those who want such things.

What has to be said is modifications to Myford lathes has been written about- for more than half a decade. If you really want to go to more erratic cheap Chino bits, the choice is yours. I've a Boxford one from their grinder which measures in tenths. There is also a standard Myford turret or you can improve things with a cannibalised old micrometer- or dial gauge. With regard to the longitudinal measurements, Martin Cleeve made a simple stop utilising the provided holes for fitting the gear box. Thomas or should I say, Dr Bill Bennett who edited both books is worth the £30 or so. On the even cheaper ML10, I have scrapped the 'Chinese metal' dials and have adjustable dials. The ML7 has these miserable zinc alloy fixed dials whereas if you acquire George Thomas's book, you will find that he drew up designs for very sophisticated adjustable dials for both machines and, of course the Myford vertical slides. You can go your own way with fitting a Myford ML7 and Super7 are well catered for for improvements. ![]()
