Calling this "fabrication" is a bit of a stretch, but if anyone is building up a rotary and is lacking the spendy tool needed to measure step wear on the plates, this little bracket thingy I made and a standard dial indicator will do the job rather well. All this is is a chunk of solid AL bar stock and an AL right angle piece bolted to it, that I bolted the dial indicator to. Pictures describe it better than words...
