I assume that anyone is doing this?

But some sources mention "never to bore/hone a RB26 without a dummy head" and all Dummy heads that I've seen today are "big chunks of aluminum". If eg. a 20mm Plate of steel does the same job it would be much easier to get one. 20mm can be easily cut with a laser (~3.5kW) or plasma. Ground flat and parallel and there you go.
Not trying to hijack K.C.'s thread, just out of interest!
