A guy I used to work with had a sine bar that had a base
which was mounted between centers. The actual sine bar was
hinged. I think he held the gage blocks and all together
with rubber bands. I suppose he used a dead center under
pressure to keep everything from moving.

**Dammit**! That is the super-precision way I have been
looking for since
long!
Thanks a lot!

I just recently came across several patents using a sine bar
to do this. See:
http://www.google.com/patents?vid=4651435
http://www.google.com/patents?vid=2398121
http://www.google.com/patents?vid=2511443

The first one looked the most promising if someone was going
to try making one. I don't know if these were ever produced
by anyone. Maybe someone here will know once they look at
them.

New ones are available.

FWIW msc only sells to companies but Enco [same company] will
generall order and ship MSC items.
You will also need a way to very accurately set the bar. Jo
blocks are best but expensive. A space block set works well and
is much cheaper.

The mere spot they stand on
does not constitute so strong an attachment
as that from which they draw their gains.

Is this new? I have bought from MSC, they did have a $25 minimum.

MSC happily sells to me. I happen to have a company *name*, but
they really don't care. You *do* have to register with them the first
time, after which they give you a number to accompany your orders.
I last bought from them about two weeks ago.
Enjoy,
