I'm in the process of cleaning and lightly oiling the ML7 but for some reason when reading the manual on line I can't seem to locate how to remove the 3 jaw chuck. I would like to install the 4 jaw to turns some square stock? Thanks in advance

It unscrews (regular right hand thread. If it's tight, put a chuck key in and rap it with a bit of wood. If it's tighter than that, search this site for one of several threads on the topic.

Thanks Bandersnatch. I gripped a rod in the chuck and gave it a rap with a dead blow hammer and it came right off. I thought that was what was needed but wanted to be sure.

Be careful about using the back gear to lock the spindle when removing chucks – the backgear teeth shearing off is common on Myfords' dainty little gears. IIRC the manual recommends putting a wooden block on the rear shear and rotating the spindle backwards by pulling on the belts until a jaw contacts the block.

MEW last month or two carried an updated LH Sparey design for a spindle locking tool that is probably a worthwhile mod if you ever disassmeble the headstock so you can drill the extra hole in the bull gear for it.

Thanks Hopper. Because I also new to metal lathes I won't think of doing anything that I think is questionable. I am at heart a wood turner and have used this method lots of times to remove a stuck chuck BUT wanted to check with the experts. Opps!! Now that I think about it I am unsure if the back gears are engaged or not!!!! So far I am just using it the way I got it but I better check. Could have been I was just lucky. New to the forum and am unsure how to find Mew's updated design?

I did try turning the ends of a wrench I made yesterday for the 4 independent jaw chuck

I got with the deal and now am unsure of the quality of the lathe. Mind, it is just sitting on a piece of plywood, not bolted or fastened down and as I turned (at the slowest speed without back gears engaged) the cross slide seemed to move across the ways on each revolution.
