Re: lathe and lubrication

What are your biggest cuts?
hello. I am pretty happy with my new 7x12 mini lathe but was wondering what size cuts others are making on cold rolled steel. I've gotten used to making .100+ cuts on 2" CRS on the backgeared South

Re: MicroMark 7x14
Here's an example, which will hopefully make it more clear why the small error of the dials is usually insignificant: Suppose you want to turn a 1/2" diameter rod to .475" in dia. You start by making

hello. Was just cleaning and lubing a new 7x12 as per the mini-lathe.com site. In that site, they use lithium grease on the dovetails and lead screws. Isn't this a bad idea? Wont the chips stick? What

Re: MicroMark 7x14
Don't be overly concerned about true inch leadscrews. The main (threading) leadscrew on the 7x lathes is true inch. The cross feed and compound are 1mm pitch with the calibrated wheels having 40

There is something to be said for a large tool bit (1/2" in our case) clamped to the top slide in the British style with a rocker style clamp and a stack of shims on the other side! Room and rigidity.

toolposts and live centers
When you mount a (fairly standard, from HF) live center in the tailstock, and have a small diameter workpiece, how do you arrange your tooling to be able to turn it? I have a TS Eng. QC toolpost. The
