Title pretty much sums it up. Right now I'm using a wooden box to set my indicator on to indicate things on my small lathe. Just looking for a couple of steel plates to rest my indicator on to sit between the ways since that box I'm using isn't what you could call flat by any means.
So if you have a couple of steel 5x5 plates doing nothing nows the chance to give them a new home. 3/8 or 1/2 thick though.
