Rockwell Toolmaker Grinder Query
A friend is offering me one of 2 Rockwell 24-105 Toolmaker Grinders that are in need of work. He has 2 of these machines he got along with some other machine tools, and they both need some work. Light surface rust on most bare metal, bushings worn/missing on the pinion shafts. Tables move but are stiff. Wrong motor on one with cog belt drive instead of 2 step pulleys, and missing belt guard and motor cover. Spindles on both seem to have oil in the reservoirs and turn freely. My quandary is that I don't really need another project, these are pretty big and heavy, I'm running out of shop space, and if I need parts, what are my chances of finding them. I have bench grinders and disk & belt sanders but no precision grinding capability yet. As a home shop machinist, (9 x 36 mill, 10 x 24 lathe, both old US iron) I'm loath to turn down tools, but how much will I use one of these?
How difficult are they to rebuild? Can I change to a single phase motor without compromising the attainable surface finish too much? Do I need to invest in a bunch of different wheels, or is there something that will work for 90% of my likely needs? Is there anything in particular I should check to make sure that either is a good candidate for restoration?
Thanks for any guidance,
