argo1 The tool I made is fabricated from a rear main cap with a single wheel from a lathe knuraling fixtue installed. It works great. You just bolt this cap on the block,with the crank installed, and then turn the crank over by hand. We used it on our Scat cranks before going to the one pc. type. As far machining for the full round seal, we alinghone the block first. This sets the location to properly machine the new seal register. Then we simply turn the block on end and machine it in our Rotler cylinder boring machine. This has been working fine on our small blocks,now I wish we could find a simple fix for the big block! Hope this information will help.
