Wow, you must have a lot of patience!!
It's good to know that there is hope to have damaged housings repaired tho
Just my thoughts tho, (and I'm not real smart so be prepared to laugh lots!!)
Could you somehow use the rotating assembly as a jig?? I mean it follows the right path around the housing, mill down a rotor to house some sort of stone and then rig up an electric motor to spin it all??

depends on the damage . i got all sort of replies. "this is what 30 mins on a roller does !"
but really they where using housings with not much more than a gloss on them .

mine are fully scratched bin jobs !
the worst took about 7 hrs . the best took 3 . the 5 housings cost 10 bux in stone . each took 15 mins to set up , then i walked away . set and forget

they are also machined. not hand lapped . pressure each stroke here consistent , same as apex seal . all the way around
( i am actually using apex seal springs and following the orbit completely, using 3 speeds to limit any harmonic chatter )
with a rolling pin and this much lapping by hand then the result simply wont be as straight and consistent
and your operator wont be able to achieve 5 housings over 3 days with a little over 1 hour operator effort
in this heat , and with carpal tunnel. that is a bigger win than most will admit

i think i can do better, slower , using a diamond roller pin ( maybe the hand one the other guys use ) and moving the housing .also set and forget .
i have something planned out . just too uber busy to throw it together in one go
