Take a look at a printing supply company to lock up type in a chase for a
letterpress they would use wedges that interlocked and could be opened or
closed with a key. They are called quoins.

Sometime back I was given a couple steel wedges, just hard flat steel
about 1" wide, 1/4" thick at the fat end and tapering down to nothing.
I have looked all over locally (Tacoma and Bremerton, Washington) and
no one has them. I found some on McMaster-Carr and ordered them, but
they are sort of a hollow ground at the fat end, not the same. And
they are relatively expensive. Pipefitters use them, I have found them
useful for all sorts of
spreading and aligning. Anyone know where to find such a thing?


In steel underwear, of course. :-)
