just sometimes not worth the time and effort to
re-engineer for a new
purpose. Also, found items seldom match up
perfectly, all complicated
by the fact exact measurements are seldom known.
How would I go about
this? Find shafts and tubes that are in what
proportion to allow a
bearing to fit? Start with a bearing? Then match
tube and shaft? I need
a "Bearings for Dummies" book or similar
resource(s). Any help here
will be greatly appreciated. BTW, I have a mini
mill, and a 7x12 lathe.
I'm a total novice operating those however.
Thanks.
