Clever gang tooling. =)

Clever gang tooling on a manual machine?

It works even better when you have "hobby CNC" and no tool changer.  I've set up 3 ganged tools like this - a small drill, large drill, and small boring bar.  I ran maybe 100 or more parts like that in mini production run style.

For anyone thinking about trying this, I'd suggest making up a plate that indexes to the machine.  Then have stations set up on that plate with known offsets between them.  This should make setup and future changes much easier.

Very clever stuff, thanks for posting it!  Looks like he added on to the end of his toolbar for the chamfering tool holder.  Man, I envy the size of that carriage.  Lotsa real estate for tools!  I'm working on a gang tool setup for my little CNC ORAC and it's pretty tight.

Shame the lathe isn't CNC converted.  As Sparky said, all those tool offsets could be loaded into Mach or LinuxCNC and a little code massaging would have those bushings piling up in no time!

If he carries on clearing the swarf with his bare hands while the machine is spinning he's going to have problems turning the dials when he loses his fingers. Definitely a no no in my book.

Do you think he was cutting metal, or, plastic?  The swarf looked like wax.  From the video, I couldn't tell.

I like.

The upper left corner of the video says it all!

Thanks Joe...
 
Just clicked and watched the video.  Never read the caption. 

How embarrassing!

Kinda interesting holding a 3 jaw chuck in a 4 jaw chuck. Guess you could use any 3 jaw without a backplate from any lathe or manufacturer, and also compensate for 3 jaw out of true as long as the jaws held axial.

If doing a number of parts the same, as he is, you could be pretty sure that the 3 jaw ran true every time.

Changing a part size might just mean readjusting the 4 jaw a little to suit if the 3 jaw error wasn't consistent along the scroll. Then you're back to true.

Smart.....

Ditto Awemason..

Baaad practice!  I bet he wouldn't be doing that with aluminium or any other material so why do it at all; lucky he still has fingers

Why didn't he have the turning tool and the boring bar set up at the correct distance and with a dti or stop to put him on the mark without all the measurement?

So that's what a 4 way tool post if for.  Silly me I've been rotating the thing all these years with 4 tools set up when I could have just left it alone and used 3.
