I'd definitely go with SeaBass on this one.... The biggest danger is becoming complacent and leaving the chuck key in the chuck. When I use the
lathe (which is nowhere near as frequently as it used to be!), I always make a check that the key is back in its holder before hitting the start
button.
I would also say that the 3 jaw concentric chuck is nice and simple for beginners, but not near as flexible as a 4 jaw. You've just got to get
the knack with a 4....
Bottom line with any machine tool is to respect it for the danger it can pose to you!

another one on the three jaw thing!!
Four jaw is ALWAYS used when accuracy is important, three jaw is fast but not that accurate.
I generally use my lathe for boring bits and bobs out and making spacers, bush tubes, top hats etc ect but couldn't do without it!!!
Its a Colchester Master 6.5" roundhead, anybody got a decent 4 jaw chuck for one???
One of the really useful little things I have used it for is welding up driveshaft adaptor flanges concentrically and square. I turn the two halves
for a press fit, put one in the chuck, and push the other in with the tailstock.
I then clamp it in with a revolving centre in the tailstock, cover all the lathe bed etc up with a thick blanket, put the mig's earth strap onto
the revolving bit of the revolving centre (so I don't weld the bearings up! ) then tack and weld round. Lathe won't go slow enough to
rotate itself, so I turn it with one hand and weld with the other, using the toolpost as a wristrest.
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning
