Tactical error....

Post by Greg_Lewis » Wed Sep 09, 2020 9:00 pm

Ooops. I admit to having done this once, but with a much, much, smaller machine and a much, much, smaller piece of material. In my case the power switch was at the left end of the headstock, which made things, uh, "interesting." (Note sig line and avitar....)

I, fortunately, have not committed that sin. Bet the boss was none too pleased.

Heh! Looks much like my experience. I had taken a part time job in a small machine shop when I was about 21 years old. I don't remember the details well, but I recall that I had to do some work on a (long) piece of 3/4" mild steel. Amazing how a piece like that can move a machine that weighs a ton or more. I strongly suspect that what you saw in that video was very much like my experience. :oops:

Yeah, this was one of the things in my life that make me cringe. I should have known better-----the same thing I often think about marrying my first wife. The current model seems to be without the same flaws (or she tolerates me much better). We've been together for more than 43 years now.

Thanks, Greg. Things like that serve a very valuable purpose for those who might space it once in a while.

Having the stop lever within arm's reach saved me from this one.
Several times.

Did mine with a 2 ft length of 1/4" dia brass rod in a 12" Atlas. Glad I wasn't leaning on the belt cover. :shock:

It happen to me too 3/8 drill rod. It beat to shred part of the shelf on the wall.

On a related subject... I put two switches on my table saw, one on each side, so I can safely reach one no matter haw I am feeding the part. The original switch was hidden below the table extension. Now it just act as safety to disable the other two.

Notice how it takes out the tool box atop the guy's rollaway. At least it wasn't a Gerstner.

Same lathe, same stock, but mine was a foot longer. As I mentioned above, the switch was at the headstock end, and the stock was whipping itself against the switch. And the power plug was behind that. I had to run outside and trip the breaker.

Excellent idea, Tornitore!

My table saw has a relay, and a kill circuit that runs to 3 buttons around the machine. Hitting any of them opens the circuit and deactivates the relay.

Lathe has VFD now, and that also has an emergency stop button. But actually, it's in the wrong place for this event.

I haven't done that (yet), but I suspect my response would have been substantially less PG...

Yes. Well... I do sometimes have to talk to my machines. My wife calls it "Navy language."
