I am really glad to see this thread pop back to the top. I read every word of every post , then scrapped my latest lathe shelf idea and ordered a proper lathe file and handle (thanks for heads up on that Chris).

I also have noticed, and heed, that little voice that tells me something is not quite right with what I am about to do. For me it's a hobby, not production. Work slow, stop for cocktails and read HMEM when tired.

In my days as a tradesman working on lathes and milling machines, I saw a guy put a 1" S/S round bar ( intending to chamfer one end using a relatively slow turning speed). The bar was protruding about 3' - 4' out of the back end of the headstock spindle.
He switched on the lathe but hadn't checked which gear it was in and it started up at high speed, the bar immediately bent at right angles, smacked the concrete, lifted the lathe off its mountings and continued to spin with the lathe doing a dance across the floor, I dived in from the tailstock end and managed to get the thing switched off with the red emergency stop button (which on hindsight was not a real wise thing to do in this case!) but miraculously no one got hurt.
Moral of the story, don't ever put a long protruding bar in the lathe without some type of steady to support it, and check that you are using a low gear!

Good point wildun;
I did the same thing on my mini lathe with a piece of brass. it damaged my antique oak tool chest and wounded my pride felt really stupid. but thankfully no injuries.

Yes, I would say that most of us have made mistakes, being careful operators or not and I would hate to see the guy who hasn't made a silly mistake proudly telling people that because one day!....................

I was close to a couple of years from retirement age and was proudly thinking to myself that I still had all my digits intact after using machine tools carefully most of my life, then I lost half of my left thumb!
This did not happen on a machine tool as you'd expect, it happened with a large (12") butterfly valve which I was helping a salesman prepare for a customer, it was air operated and I was trying to mount it in a vice - he couldn't wait to try the air on it, then it slammed shut .... on my thumb! - the rest is history.

My lathe tools go back to the tool box on the right when I'm done with them and hammers, files, etc. are in the drawers beneath the lathe. That can of cutter is even gone now replaced with insulation.

I just finished reading all these post and would like to say the gentleman with the mini lathe is worst off a Dc motor just keeps turning until something breaks. I've seen a man loose a finger in a punch press, I've seen a man cleaning an inline production drill get wound up in the drill and if his shirt had not been torn for his neck he would have been killed this was a multi drill head for a V6 engine at very high speed. What my biggest pet peeve is gloves I don't care what you are doing any time you are near a moving piece of machinery gloves are a NO NO. Had a guy ground he's hand very nicely in a belt sander glove caught suck his hand right in. I have cabinets above my lathe for tools, but I work of a roll around and if I do reach for a tool my chuck is passed the end of the cabinets.

I've was thinking more on this subject and I have to ask what do you use to keep chips away when making cuts? How many have learn that if something is rolling to let it go don't grab it?
I was taught and always have used a brush to move chips, I've eaten up a lot of brushes but never my hands. Any kind of brush will do and if it gets caught let it go they will make more.
I also learned to let things fall it's a natural instinct to reach to catch say a pencil rolling off a desk. As I learned and was taught don't ever reach because you see one thing and your mind see another. It takes a long time and concentration to be able to let it fall. Now at times I still catch things but I've trained myself not to around machines and I'm proud to say I still have 10 Toes and 10 Fingers.
How many wear steel toed boot? I still wear them in my home shop I dropped 580# of steel on my foot when a slide broke the stops and fell on my foot. The on damage was it drove my foot down so I broke the second joint to my big toe, the shoe was intact and it never bent the steel toe.

I did some flying in years past and this reminds me of an old pilots adage: There are two types of people who fly aircraft with retractable landing gear. Those who have landed with the gear up and those who have not yet landed with the gear up.

I have not YET done the long-bar-out-of-the-back-of-the-headstock dance.

Todd, I thought that was what old toothbrushes were for - short bristles that dont get caught or wrap around moving parts, & cheap. Good for applying cutting fluid too !
