Hi all,
I have just bought a myford ML7 lathe, good condition and a very good price, despite having a slight problem. (Well 2 actually, but I am asking about 1 of them here)
The problem is that the cross slide nut is not fitted or available. I have checked the compound slide nut and that seems to be exactly the same, so at least I can use it (apart from the other problem).
The nut on the compound slide looks to be made of aluminium. I am assuming that if I fabricate another, it can be any material that is not ferrous, so I could use brass, phosopor bronze etc. Am I assuming correctly?
As it is an acme nut, I am going to have to screw cut it. Trouble is, I have not cut acme before. (I have cut square). Any tips?
Alternatively, if anyone has a cross slide nut lying around, not doing much, I could be interested. (Saves cursing with broken internal threading tools, mismatching threads etc.)
The other problem (I thought I had solved) is that it is currently 3 phase. I bought what I thought was a single phase motor, though when I plug in the motor, it buzzes. If I hand turn the armature then switch it on, it rotates quite slowly, and I can stop it with my fingers. Doh!!!
Cheers. Dave Colliver.
