If your lathe has a gap bed take similar precautions when it is removed. I use a wet/dry vacuum with a tube nozzle to suck out residual coolant at the end of the day, however this may not apply to your machine.Īlways place a piece of 1/4" plywood or similar material on the bed when changing chucks or setting up. My old Harrison has felt wipers on the ends of the saddle which tend to hold coolant like a sponge, this can cause staining and etching of the beds if left when the lathe is not in use. An old vacuum cleaner is very helpful for cleaning. Wiping and oiling the bed frequently and covering the machiine with an old blanket when not in use can only help. But its impossible to totally prevent this problem. If you can cover the front of the carriage and bed with a suitable cloth without it becoming caught up in the chuck, workpiece or leadscrew/feedshaft it will help, this can also save time in cleaning the lathe particularly if you only want to do a small quick item such as a brass fitting or to get rid of the mill scale from a bar and then remove the cloth out of the way.
It is the fine dust from materials such as Cast Iron, Brass and mill scale of black steel bar that are able to work their way under the carriage and cross slides that do the damage in these areas. The spindle should now turn smoothly yet freely, but still be very slightly stiff.I thought you might like some tips for looking after your lathe. Tighten NUT A fully, and hit home gently with a soft faced hammer. Tighten NUT B carefully with a C spanner, until the spindle has become stiff, with a jerky motion, but can still be moved by hand.
It is likely there might be some small movement due to wear. NB there should be should be a visible scribed line marked on the spindle, which should line up with the split in the collar when new. Holding the bull wheel or pulley, tighten the split collar by hand. Continued: Super 7: General Specification and comparison with the ML7 When it appeared in late 1952 it was immediately obvious. It comes with the Myford quick-change screwcutting gearbox, power cross-feed &. The serial number indicates around 1978 one of the last grey machines built.
