The beauty of chiseling was that often they wouldn't come off clean and smooth,
which helped in positioning the pneumatic when we glued them back on.

I was taught to drill shallow holes through the pneumatic into the
stack, and put short pieces of steel rod (cut 3d nails worked) into
the holes, so that they could be keyed back into their exact original
position.

Those were the days. I'm better for the experience, but I'm happy
they are behind me.
