I tried to pick out some stuff you guys wouldn’t normally see. Enjoy.
Awesome, thanks! Regarding the second video - I actually want to try that myself some time, but read that for some reason there sometimes is a small error in the spacing of the teeth. Did you encounter something like that? And if not, how did you calculate the diameter of the worm gear?
I’ll admit that was actually just a play experiment. I happened to get lucky that the size worked out ok. To actually calculate it you would need to figure out your circumference of the part in relation to thread pitch and tweak things until the numbers matched up.
A quick example if you had parts with a 2” and 2.077” circumference a 13 tip tape would work but on a part with a 2.037 circumference you would end up half a tooth off.
Love watching lathe in action :+1:
I did not know you could do number 4 with a lathe, is that safe? Everything would be out of balance? What is going on there?
It’s perfectly safe, the lathe handles it quite well keeping in mind it’s 30 horsepower and a 12” chuck. That part is about 4.5” diameter and 1” thick. For larger parts we will bolt a counterweight to the outside of the chuck.
Your right with stuff I haven’t seen before. The first video I’ve not seen a carbide drill like that before.
The third one I loved the F1 noise rendition and the worm wheel gear cutting. Does the material get turned by the cutting tool?
Thank you! I shall get the lube and tissues ready 
Yes sir it does. The cutting tool is just a common tap in a collet on our little manual lathe. I just put a pin in a piece of bar stock that fit the brass round. Clamp that in the tool holder on the lathe, center it, and feed in slow. With lots of oil…
