So my question is: Is there anyone who has an idea about what I might be doing wrong? Would there be some other thing I'm overlooking? If I do get a threading-like result, it's not the correct one. I do enable the wheel on the right (the small wheel that should lock the feed, and assure a proper thread (I think)). While the chuck is turning (lathe on.), I can use two feed speeds (handle 1 (goes up or down) and handle 2 (turns clock/counterclockwise)). In most cases it's as if I'm just turning instead of threading the piece. But, and this is my real question, none of them give a thread that comes even close to it. One of these four combinations should result in a 1.75 metric thread. Let's say that G(gear)1 and G2 are the big ones, and G3 and G4 the smaller ones: Since I didn't know which gear to combine with which gear, I tried every combination. I have to combine a big with a small gear. I've got two big ones and two smaller ones. The question is what gears I have to put on the lathe. Nothing difficult: for 1.75mm (metric): sliding gear out - 9 - C. The table on the lathe show the settings for both Widworth and metric threads. I've use a Celtic 14 in the past to turn lot's of different tools and such, but I'm having difficulties with this particular lathe when it comes to threading. ![]() Since I don't have a manual and that I can't find one on the internet, I started googling for information.
