I finally used only the #1 line (its was graduated with four numbered and four unnumbered lines) and it worked just fine. BTW the Clausing in question had an imperial lead screw. This is the kind of thing that continues to baffle me about using different lathes. My lathe has an imperial lead screw, 8 lines on the dial (4 numbered), but for metric threads once you open the half nuts you are done - game over. They have to remain closed and I run the carriage back in reverse. There has to be an odd gear ratio in there somewhere along the drive train. But I suck at math so......

Well this project is intent on never getting finished. I started turning the new blank to replace the butchered one and my DRO said I had .025" to go. So I thought I better make a measurement. I should have been at 1.300" but it was at 1.200". I must have keyed in the starting dimension incorrectly. Now I have a nice piece of bronze that I can hopefully use for a bushing in the future.
 Ed EDIT: make that two pieces. The first butchered one and now this new one.

Been there, done that. Don't beat yourself up about it, I'm the master of impatience and resultant stupid mistakes, not you.

Misery loves company but I'd rather you keep that master status.I'm not all that concerned about it. It's only $3.85 worth of bronze. I'm sure it'll get used for something eventually. Ed

I have a RH 1-1/4-5 ACME elevation screw and nut mounted on my wall to remind me to always specify the EXACT details of a thread when drawing it up for someone else to make

This is on my 'wall of shame' to remind me that they work better when run in the FORWARD spindle rotation.
Getting in a big hurry doesn't work for me. Ever. ![[Image: Half-inch_end_mill.jpg]](http://img.photobucket.com/albums/v82/Highpwr/Temp/Half-inch_end_mill.jpg)

Even a $2 tool that worked good once or a workpiece with a little time in it hurts when you trash it. Time wounds all heels. Or something like that.

If it was close to being worn out, I wouldn't have cared so much. I love the way most of the "pro's" on YouTube leave their "whoops" moments in their videos and don't edit them out, showing that we are all human and make mistakes now and then. Good judgment comes from experience, and experience comes from poor judgment. A good question to ask oneself is "If I do this, and something goes wrong - how badly am I going to hurt myself?"
