Bob, I will defer to Don with regard to bearings. You don't do 27 years service at Torringtons without picking up a thing or two about bearings!!
I might be talking tosh but would it be possible to metal spray the bearing surfaces prior to grinding. As to case hardening (again I am not as engineer so I may be talking out my back*****) couldn't you heat to cherry red and with some case hardening compound and let it cool in sump oil? D.I.Y. case hardening!
Where I am on firmer ground is that I can confirm that 'Lumiweld' is indistinguishable from aluminium and in my opinion is ideal for "filling". Also, if you have any stripped threads the hole can be filled, drilled and tapped. The other day I was drilling some fixing holes in a length of aluminium cope moulding and I inadvertently drilled in the wrong place. The job looked ruined but after filling the hole with Lumiweld when filed down and finished off with fine glass paper, the mend was invisible!
Are you familiar with Click Metal? I have found the service to be excellent.
