That's old mate from Indonesia, Mekanik Mesin. I posted some of his amazing videos a while back here LINK Well worth a look. The guy is a genius at doing almost anything with almost nothing. A very clever machinist with many great ideas relative to the home workshop where we don't have the resources of industry at our command.

This latest scroll machining attachment is pure genius and his best effort yet! But sheesh, he is not shy about arc welding right there on his lathe is he. No anti-splatter spray I am sure.

I wondered where the weld current was going on its return path, not good to return through bearings and slide ways. A very clever device though.

A device for cutting grooves in bushes is nothing new. Please see page 455 (462 of the pdf file) here:

Note that this book was first published in 1907.

Edit: turn over a couple of pages above and there is an idea for the person asking on another thread here about turning a crankshaft.
