Micrometer Saddle Handwheel - Myford 7 Series

Axial movement of the saddle on Myford's lathes is difficult to judge. Using the feedscrew handwheel has it own special frustrations: it's a long way from the work, one turn gives 125 thou. and there's no way to 'zero' it. As if this weren't trouble enough, one must engage the feedscrew and disengage the tumbler-reverse before it can be used....

Graham Meek thought long and hard about this problem and came up with a superb solution. The rack and pinion drive on the lathe's apron produces 0.860" of travel for each turn of the handwheel. This permanent fixture, sandwiched between the pinion gear and the existing saddle handwheel, changes the travel to 1.000" per revolution and includes a large 'zeroable' dial, marked with 100 x 0.010" graduations. Armed with this wonderfully convenient item, axial measurement to an accuracy of 0.003" or better becomes child's play. Fantastically useful for locating external and internal (blind) features on a job!

No batteries or microchips here - the robust design uses 4 gears in a planetary arrangement to translate Myford's gear ratios. Accuracy over 10" of travel is typically 9.9994". A metric geared version is also available to give 25.00mm of travel per revolution with 100 x 0.25mm graduations. Please choose from the list above.

Unusually for Hemingway, this item arrives fully complete and ready to fit to your ML7** or Super 7 (including the Big Bore) lathe using the fitting notes and fixing provided. The workmanship is in everyway comparable to Myford's and we are quite certain you will congratulate yourself for making this investment!

Please Note: Availability of these units is limited. If stock is not available at the time of your order we will send you an estimated shipping date which may show a lead time of up to 8 weeks.

** NOT suitable for earlier ML7 lathes (before Serial No. K111727 - April 1973) fitted with a smaller, Ø3/8" pinion shaft. We are working on a solution for these - please let us know if you are interested!
