Mc 900 variable speed lathes
Another question.
Does anyone know why an MC 900 generic lathe, 6 spd. may not hold 6th. speed. The lever will not lock into 6th. and slowly returns to the 4th speed where it stays and holds this speed.
Any help or ideas appreciated.
Cheers

Broken Reeves pulley?
The speed should only be changed while the lathe is running. Sometimes the collar of one side of the pulley can break away and while the speed control still partially works, it's via friction between the broken parts rather than being a fully functional interface.Franklin

There are a number of variants of shaft size and pulley for these generic lathes. Hare and Forbes have at least one pulley set available Just a moment... which may or may not fit your model.
There may be other problems. A few old threads here such as MC900 help please!!!! might be worth looking into as well.Franklin

Had one for several years. I would check the drive, its more than likely theres some crud on the shaft. The pulleys should move effortlessly, be careful what you lube it with as grease or oil attract wood dust and many use dry lube some will leave a build up on the components.
