Hey Jeremy,
Drop by any time (well call, text or e-mail me to make sure I'm home
first) I love to have visitors here in my little corner of Swamp East

Yup, I agree! if the keys were tight enough to get a few tenths

The photo is rather small, is the calculator small with tiny print? My

Just for S&G what does your calculator say for drilling a 1/2" hole in

Hi Stuart,
true, but it's much easier to just verify that the alignment is correct
than to align it without a key ;)

Gentlemen,

"DO NOT TRUST KEYS TO ALIGN VISES AND HOLDING FIXTURES!!!"
always verify the alignment with appropriate precision devices

I do that when making
All I can say... Is that I have had the cheap vices and tried to get one
ground even to be flat and square. The reality tho is that if you really
want to make parts and not screw around with things and waste time, the
Kurt vises and some of the other top end vises are worth every single thin

M53 is Feed Stop Control, it enables the feed-hold pin, it doesn't

For a specific machine table it possible to imagine 3 (or more) square

I am fairly sure that Smithy will be quoting LinuxCNC behaviour, but I
agree it is not the obvious place to look.

All Kurt vises are keyed on the bottom. They even sell the keys in
different stepped widths IIRC. My import vises are also keyed the same
(but included the keys and have to be ground down if you have something
other than a bridgeport sized slot.) So maybe the guy wasn't so clever;)

I keep meaning to fit a key to the bottom of my vice.
Or alternatively, something I saw on the internet
I'm always amazed that people will read documents for other things and
expect them to apply to LinuxCNC...

I saw a clever plan once where the guy attached a square piece of steel
to the bottom of the vise. The steel fits the table T slot precisely. He
then lined the vise up and tightened the piece of steel in place. This
way you can remove the vise and replace it ti the same alignment every
time. An

If you mill them in-situ then they will be perfectly square and true
too. Until you move them.
