A sticking carriage return lever was discussed somewhere on this Forum.  I weighed in.  Our Illustrious Moderator also weighed in--with a good point:  It could be perhaps that the lever was tightened down too tight, and backing off a little with the bolt holding it in place will perhaps remedy the problem.

This brings us to the topic I have chosen for discussion here:  Tightening screws, nuts, bolts, or some other fasteners too tight--or as we call it in Texas--"Booger-Tight."  Booger-Tight is so tight, you blow on the bolthead, and it'll snap right off.  Often, the slot or phillips holes will be so badly chewed up, you won't be able to budge that sucker ever again.  You'll probably have to break it off and/or drill it out and start over.

Now this is a problem not only in small machinery such as typewriters--I've worked in heavy equipment rental where they repair bulldozers and excavators.  Yes, booger-tight lives there too.  I've seen Catbolts broken off--done it a few times myself, and then I found two magic words--Torque-Wrench!!

It makes me wonder--even though after a few decades in typewriter repair--do they have a torque wrench small enough to use in typewriter repair, or any other small machine for that matter.  I know it's a silly question--to which I should know the answer.  But, since I have no need of such a tool myself, and it would probably be too rich for my blood to obtain one.  But, still, I wonder if one does exist.
