My first machined screw


Recommended Posts

It's an M3, to make practice for a comparable, but non-standard size and pitch one that I need for an antique clock restoration. Slowly getting there and then I will tell its full story.

This is what I've used, nothing to do with watch or clockmaking, but for various reasons it was the best purchase for me at this time.

Looks great, did you cut the thread with the lathe, or with a thread cutting die? M3 means M3, with a specific pitch of 0.6mm. Most dies would be M3, but there is MF 3mm with a 0.35mm pitch.

Yes, threading practice, tried some techniques like tool upside down and spindle in reverse, and cutting with compound set at an angle.  BTW here where I live M3 is 0.5 pitch 😁

    • A small but mighty achievement. Well done and thanks for sharing.
    • Excellent project and I am looking forward to furthers posts.
    • It's a mix of equipment and technique. For getting a finish free of microscratches on stainless steel, I use loose 4" cotton wheels and the Menzerna family of compounds. I step down from blue (if needed) to pink to yellow to white. In between each step, clean the case with a steamer or an ultrasonic cleaner. You can get true mirror polishing, with no swirls or scratches under a 10x loupe and raking light, this way. An underappreciated side of this level of polishing is contamination. Different grits shouldn't be used on the same wheel, or course, but think also about your fingers, how the piece is cleaned and wiped down, and so on. A fine finish will be scratched if a piece is wiped or dried with something that has old compound residue on it.    
    • I've just finished watching your video jd. Excellent work as always. As I said in the comments on Youtube it wasn't boring for me. How about some brass plates for your vice they won't leave marks on your jacot tool.  
    • For those who were curious of what the 7750 flash-files contained and didn´t have time to download the swf files I did a small compilation of the [email protected] application a while ago. In this PDF you also get some extra information. So no need for a flashplayer.....   ETA 7750 HSL EDITION.pdf
