    Machine tools no longer have hand cranks. airplanes no longer have propellers, typewriters have turned into computers, yet
    wood working machinery looks about the same as it did 100+ years ago. The obvious addition of screws and dials to make
    the machinery more efficient, productive, and easy to use has not carried over.
    Puzzling....
    Dan, you're thinking of the stuff seen in Home Dispute and similar. You need to get out more.

    Small upstate NY shop 7 axis, no cranks.



    One thing about us routine small time woodwhackers: a guy from the 17th C (1600's) would recognize most of our products, and even our clients. Not so true for metalworkers. When you get into industrial woodworking or commodity wood product production, it's just like metalwork, only maybe bigger. Been that way since the early 60's.

    I have a pattern lathe in my shop that is 75-100 years old. It has a carriage etc. just like a metal lathe and is great for roughing and straight and tapered cuts but for contours and other shapes a hand held scraper or gouge and templates are much faster and as or even more accurate. My other lathe is a post lathe which is a lathe with no bed it is only a headstock and the rest is portable and can be moved around. I can turn up to about 9' diameter the shop I bought it from had it mounted over a pit so you could turn about 20' diameter. I don't know how much a lathe with a carriage etc. that could turn 9' dia would cost but for it is too much for a machine that might get used once a month.

    Since I bought my CNC router about 3 years ago I have not needed the post lathe and I think I have used the other lathe once quite a few of the of the jobs I have done on it are jobs that at least part of the job would have been turned.

    I did exaggerate a bit. More like 5 active axes, + (currently) user set rotation in front of wrist, and user set tool slide. Plans in that shop are to blow out a wall and put an opposing 'bot to carve the OD simultaneously with the ID.

    Here is one solution:

    Mast Lathe - YouTube

    The spar shop can turn 40 inch diameter and 120 feet long. Video shows lathe with slow turning log and traveling cutter.

    Some of my tools were originally owned by a patternmaker who was killed turning a corebox that came apart.
    I worked with an older guy that was there when it happened. He said the man's head was mush, and the chunk knocked some blocks out of the wall of the shop.

    Had I been standing in line with the corebox that came apart on me I would have been badly hurt and quite possibly killed. I get a chill thinking about it now.

    You all might like this- making a huge taiko drum- the chainsaw work is astounding.
    Unfortunately on this video the turning is not shown, but it is clear there was a lathe of some type involved fro the turning marks.
