I had the privileged of seeing lostheplots nc mill in action last weekend. He is one very smart cookie. To say the problems he had to work out would have put many others off but he stuck at it and made a terrific machine. Now what do we all want made. Smile
Ah, had a great ride with him, lostheplot and my nephew as well. Beer

This rudimentary device I cant take credit for but is very handy for trueing thin parts in the lathe I think the thicker the shaft the better !{width:50%}https://imagizer.imageshack.com/v2/800x600q90/922/oWihfE.jpg! simply clamp part gently in chuck and move the bearing in till it rotates continuously stop the lathe and tighten chuck completely.

What I do is to use a large square, (ground on all sides) tool bit and hold it tight between the work and the chuck face for a quick fit up.  If you have a large enough space behind the work to slide it between the jaws.  You may be surprised how true it runs for general work.  Just be sure to pull it out before spinning up the chuck yell

I made one of these out of a bicycle seat cam lock several years ago and it is a very useful tool on a lathe.
You attach it to the bed rail and move the carriage to where you would like to stop turning on a work piece. Then push the carriage stop up against the carriage and turn the handle locking it in place. So every time you move the carriage towards the chuck turning down the work piece it hits the carriage stop and the carriage stops precisely in the same place every pass.

I have plenty of light above my lathe but for inside tubes etc… it’s not so good. So I slid a magnet under the clip of an at40 so it can easily be mounted just about anywhere on the lathe

Is that a new tool holder?

My tool post spindle is great but it has limitations. The ER collet is so small i can only fit drill/dremel bits up to 3mm. So I’ve made up a new tool post spindle that should be able to handle much bigger stuff. It mounts in the same clamp block as the old one. I had some grief when i pressed the bearings in, it was a little too tight for the tools i had and used the big vice at work to get the job done. Unfortunately it’s squeezing the bearings enough to make the spindle feel a little stiff. Hopefully it’ll wear in…

I tested the spindle speed with a tacho i don’t really use anymore. I was hoping for a little higher revs but to be fair the squished bearings are producing a fair amount of drag/load. I just need to make a neat spot for the electronics then it’s ready for a test run.
