Yet another Chinese-built Myford copy but this time a curious mixture of ML7 and Super 7 with parts (resembling those) from the latter including the tailstock, a roller-bearing headstock, hinged covers over headstock and changewheels - whilst from the former the simpler form of cross and top slides was used and there was no clutch fitted to the countershaft
A variety of interesting problems was reported by the original owner - a set of difficulties that took some time and trouble to rectify with modifications and changes necessary to the tailstock, motor-support platform, belt tensioner, saddle gibs and change-wheel carrier. As an example of the hasty and cheap manufacture incorporated in the machine the tailstock clamp assembly was so poorly made that it was put aside as a souvenir of exactly how not to construct such an item. Under prolonged use one especially weak point came to light: the type of bearing used in the countershaft which, if the tension of the drive-belt was set too tightly, tended to overheat and seize - something the original Myford design (which employed plain bearings) never did. In place of the long-lived and reliable plain white-metal bearings of the ML7 headstock the makers of this lathe used large roller bearings. Unfortunately this theoretical improvement had been engineered with such poor attention to detail that it proved a retrograde step: not only were the arrangements for taking bearing pre-load poorly thought out but also so badly executed - the locating sleeve in the spindle pulley stack, for example, was the wrong size had been packed out with an odd length of badly-fitting tube that rattled uncontrollably.
