I first built my wood lathe 33 years ago. At that time up here (Near Tamworth) I couldn't even buy lathe tools because the hobby just wasn't too prevalent. Its a very simple design, using 2/ 150mm X 75mm heavy channels welded web to web. A 6mm cap welded on top and 2 plumbers bearing supporting a 25mm shaft. Step pulleys on one end a 1" X 8 TPI male thread on the other. The bed is made from 2 pieces of lift car tracks that are about 75mm X 75mm in a Tee shape. well that was enough and I was away. The first thing I turned was an Oregon bowl about 200mm dia and cut with a flat file ground into a scraper.

A couple of years later I did a day's work for a mate and he made up the tail stock with a #2 Morse socket. The hand wheel was rescued of a farm tip and was the hand wheel off an old sewing machine. It may be a little crude in some places but it works fairly well.

The tail stock and tool rest were just bolted down to the bed with a ¾" bolt and nut and tightened with a ring spanner. That worked well but as time went on it started to get a bit tedious to move the Ts & TR and I noticed that most new lathes had a banjo locking device. Well I finally got around to making my own version. I used eye bolts with a 20mm hole. It took me 2 days to do them but now I am "as modern as tomorrow" with my old homemade lathe

I did some turning with the new banjos and boy they make a big difference to moving the TR &TS. Why didn't I get around to it earlier. I am now making a banjo set up for my 100+ year old metal lathe. Its amasing the work you can do in your brain and have no mes to clean up

Now that is inspirational. You needed one and just made it.

I think we all have it in us to do things like that and this is part of who we are.

Ah Christos. You are sounding like one of the great philosophers. I think it is in the genes. My Dad was born in 1914 and his Dad died in 1917 leaving Grandma 5 kids to look after. As the family grew up money was short so they had a "make do" attitude to get by. As I was growing up I watched my Dad do all sorts of things around the house because he was quite handy. Then when I went to work as a Carpenter I learned an awful lot about other trades as well so I ended up being able to do all sorts of things in the building line. I enjoy working with anything wood and have that same joy working with steel either machining or fabricating. The optimal goal is to get a good finish off the metal lathe. So far it has alluded me as my finish is usually "fine threads" on the surface. One thing though I keep trying searching for the"Holy Grayle" of a good finish off the metal lathe.
