5 forum posts | Hello everyone, I'm based in Hertfordshire, retired. I have an interest in most things mechanical and have quite a large workshop in my garden. In which I among. other things build engines and transmissions. (should that be rebuild?) I have a Warco wm 250 lathe, a 1946 Myford Lathe, Ajax mill (same as Warco Major), and other assorted tools and equipment (tig welder, chop saw grinding disc type) etc etc. I will also admit that my main reason forJoining is for some help and advice regarding my Warco lathe, which will be the subject of another post shortly. I have also read some of the threads here regarding wm250's. Sam |

7227 forum posts 21 photos | Welcome Sam! A 1946 Myford sounds like it just predates the ML7, so might be M type or one of the ML1, 2 ,3 or 4 types. All will be pedestal type beds, with the Tailstock end cantilevered out. The M type was based on the Drummond, I think. The ML1 and 2 will be 3 1/8" Centre height The ML3 and 4 will be 3 1/2" centre height. The odd numbers will be 15" centre distance, while the even numbers will be something like 21" centre distance . Spindle nose is likely to be 7/8" x 12 tpi on a 1946 model (The earlier ones were 7/8 x 9 tpi - 7/8 BSW ) The change wheels will be 20 DP, 14.5 pressure angle, driven and compounded by 3/32 pins. If there are any missing, they can be replaced by modifying ones from a later ML (Which was launched in 1947 ) The bore and thickness is the same, just that the ML gears were driven / compounded with 1/8" keys. So all that is required is to butcher one of the existing gears to use as a jig, by drilling through . You then mount both gears on a 5/8 (From memory ) arbor and drill a 3/32 hole half way through the "new" gear. You probably know this but: The Leadscrew is 8 tpi but will need a two stage train to move the Saddle towards the Headstock, under power. The other "peculiarity" is that rotating the Saddle traverse handwheel clockwise, moves the Saddle towards the Headstock; the reverse of what you might expect. Hope that this is not teaching granny to suck eggs, and is of some help Howard
