Nick was pretty excited about this recently.

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

http://www.google.com/patents?vid=3389473

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.

Alternative to those, see if you can find a Mini-Sine. It's a 2.5"
hinged sine bar with a mag base, and was made way back when by Kingman-
White.. I wouldn't part with mine, but did recently locate one on e-
bay for a co-worker.

New ones are available.

Some sources in the US are

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.

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,

What you are talking about is a kingman white 2.5 mini sine . I love mine
sadly they ain't made anymore but can be found on eBay don't be shocked when u
see the price . The were over 4 bills new . If you get one without literature
be sure to add .100 to your stack up . As the one roll is smaller this lets
you stack smaller tapers

I saw your August 2016 post concerning the Kingman White Mini-Sine. I also
have one, but am missing the single sheet instruction manual. Do you have a
copy that you could scan for me, or direct me to someone that does? Thank you
for your assistance.

Nick left this group a long time ago. Bummer... he was a smart guy.
Couldn't handle all the political crap and off topic posts...

You might be able to get a message to him via his youtube channel:

https://www.youtube.com/user/MuellerNick/featured

It looks like he may still be active there.
