Don't run the boring bar into the chuck jaws on the end of the hole

[Downunder Bob]

Glad to say I have yet to smash the chuck on the carriage.
But, I have, however, dropped the 6" 4 jaw on my hand unscrewing it from the spindle... I suppose better bruise my hand than damage the ways.....

I always like to place a piece of wood across the ways when removing or installing a chuck also when fitting large heavy objects into a chuck, and yes, always keep your hands out of the way.

The reason a VFD does not over heat the motor is because motor heating
is mostly caused by slip. Motor lagging behind phase. The VFD changes the
timing of the phase.

Boring bar mishap...
I've hit my chuck a few times but my chuck jaws is so hard the cutter squeaks
when the cutter hits it and does not hardly even leave a mark. I have one of the
first large Grizzly lathes made back in 1987. It's been a good one.

Years ago when we had our manufacturing business, I was on the advisory board for a local tech collage. In one of our meetings, one of the schools instructors made the comment "There's nothing worse than seeing a student crash a machine." To which I replied, "Oh yes there is, PAYING someone to crash your machine!"

Don't run the boring bar into the chuck jaws on the end of the hole cause you're watching the dro and not the work...
