The
wrench is completely assembled now.
I had previously cut a hole in the body tube so I could see the tilt
block assembly. The body is very hard steel. I wore through a couple of
Dremel wheels cutting through it.
Note that the bottom of the ratchet head is on top, the anti-windup
assembly below, with the tilt block interposed between them.
I've cranked the handle up the torque scale, screwing the calibration
shaft into the body, squeezing the main spring, putting more and more
clamping force on the tilt block. At this point, if I tried to
remove the cross-pin at the top of the body, the whole works would
shoot out the top with some force, like a jack-in-the-box, and go all
over the shop.
Now what happens if we actually turn the wrench and try to tighten a
bolt? Keep reading...
