This is probably old hat to most of you guys but, it's new
to me as I've never had one or even had my hands on one.

This one I made in my shop using a cheap digital 6" caliper.

I made it because I was having an awful tough time trying to
get a reading of the height of a part while hand holding a
dial caliper and just could not get consistant readings.

Once all the parts were assembled, I locked the caliper
and "lapped" the base unit and the extended jaw as
a unit using progressively finer grits of wet dry paper
on my surface plate.

The digtal caliper reads 4 places to the right of the decimal,
although the last character either reads blank or "5" for
a half a thou. and nothing in between.

The gauge seems to allow a much more controlable reading.

Anyone recognize the red thing just to the left of
the newly made height gauge?

It was given to me a couple years ago and tucked away for
a while as I did'nt really know what it was, and it was stiff
as a board and did'nt seem to rotate.

Well, during a recent rearranging, I found the red thing
and decided to disassemble it, clean off all the old dried
up grease/oil that was acting like glue preventing it from
rotating, and re-oiled and assembled it.

It has a collet that I had'nt seen until now.
The collet looks like it's made more of "air" than metal.

Looking up on google images I found out that it
is a collet for the work head of a valve grinding
machine, which is what the "red thing" actually is.

Google can be a great help huh?

Can you tell what I'm up to with the work head
and the spindex?

My plan is to convert the work head into a tailstock
to use in combination with the spindex on the
mill table.

The height gage allowed a good reading to determine
the amount the work head needs to be raised to
bring it up to the same center height of the spindex.
