    Plenty of ex-soviet tooling around here!

    Much if it is quite decent, usually better made than chinese stuff, but not up to today's standards. Definately usable and affordable for a small shop,...

    Nice shooting toys you've got, guys!

    I know Swedes have residental 400v 3-phase like most of Europe. So just plug and play for industrial machines, no fiddling around with voltages and phase converters... :) It's uncommon to come across...

    Certainly not possible. Would you fly a jet liner with your eyes closed because you're afraid of heights and dislike them?

    In theory, you could but in real life you can't. It would involve lots of...

    I did a bunch of parts like this in the past. Those were capillary tubes 25mm long with a 1.5 and 2mm holes through.

    Biggest problem was the drill wandering around. I first tried drilling the...

    Excellent idea!

    Many of my parts have milled flats, grooves or holes on the face, rarely needing more than one live tool. I'd consider some kind of (manual) indexing mechanism for the spindle as...

    ..The Takamaz Miniturn has landed on my shop floor! :)

    It's indeed a tiny machine for making tiny parts. Despite it's size, it's heavily built. At 1080kgs, it's twice as heavy as a Haas OL-1,...

    One place i used to work used neutral toolholders for roughing out trapezoidal threads. They then used a full-profile threading insert after roughing.

    How many you have to make of these?

    I'd consider a brazed carbide custom tool. A tool ground from solid carbide or HSS might be viable as well.

    I think the P and Q values are way too big. How did you figure out those numbers?

    Q on the first sentence of G76 sets the minimum depth of cut (in radius) while roughing. On the second sentence of...
