Screwcutting Gearbox - Myford Lathes
"Machin" Screwcutting Gearbox - Myford 7 Series
"Machin" Screwcutting Gearbox - Myford Series 7 Lathes
Ref: HK 155X
Developed from the Algoa Screw Cutting Gear Box, but using castings instead of the original fabricated structure. The gearbox is suitable for the Myford 7 Series range and provides a truly enormous saving over the commercial item.
Gears; make or buy? All of the 21 gears are designed as Myford standard 20DP and all except a single 18t gear, can be adapted from standard 20t - 75t change wheels. However, Machin gives elegant instruction for making the gear set from sawn blanks. The Versatile Dividing Head with Milling Kit could make light work of this task. The design retains Myford’s standard change wheel quadrant, allowing metric pitches to be cut in addition to the significant range of imperial feeds.
"Machin" Screwcutting Gearbox - Drawings & Instructions
Ref: HK 1550
26 drawings and 38 instruction sheets including 52 process photos. The information provided by Machin is exhaustive, including a number of "recovery steps" should things go wrong. Instructions are included for photo-etching the 2 data plates. Order the plans first and you will be reassured that this is not one of those epic projects. One experienced customer completed the full internals in 2 weeks and then ordered castings and bearings!
