can anybody tell what the name off the threading tool on this lathe video is called?

Hi Chris,

It's called a tapping head. It has 3 or 4 sets of "jaws" that have the thread size machined in them. When it reaches the correct depth of thread required, it releases. They cost anything from £200 through to £2000 plus the jaws.

im guessing for home use a tap and die woud be a bit cheaper, lol and just as good when done right.

Ive only recently started welding, wanted to do some car repairs and some other projects. i evidently bought a arc welder instead of MIG. lets just say i spend 1 min making a big hole 30 mins filling that hole back in again, 20 grinding and then i have a really crap weld. I'm guessing it should take like 30 sec's with the right tools.

didnt know where to post saw the movie lol but its relevant as im cutting a 4lb rocket rammer, enjoy .
on a lighter note i found this page on pulleys most helpful when working out belt and pulleys speeds, maybe helpful for people building ball mills
