View Full Version : Hieght gauge

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.
