Awhile back I bought a box of flanged ball bearings to upgrade some Parma controllers I had lying around, and according to the box they are 1/8" ID x 1/4" OD.
I also have a couple of tweaked Monogram brass chassis here missing a rear oilite. Of course, the Mono oilites have a weirdo OD, too.
Is it worth the aggravation to drill/ream out the bearing holes and solder in these ball bearings, or should I just look for a couple of NOS oilites on the Bay? Both of these have already had some soldering done to them already so I can't imagine they have much collector value.
