On edit: added info, and why are they specifying a rather close tolerance for the thread relief at the shoulder??
ToolCat
Don't you know that only really good engineers specify really tight tolerances?
"Bad" engineers specify loose tolerances.
Probably a piece of ground support equipment. I'm working on one nows. Stupid
thread relief dimensions on the nuts on each end, angles, radii (I want to type radiuses),
diameters. Just retarded, but there are a bunch of other places on the shaft that need
a corner relief. One is just a simple groove. Some are .007 radiuses (take that Radii!!!)
to a square corner, and some others are 13 degree reliefs going into a .015±.003R corner and
a moderate tolerance on the diameter. And then there are places the shaft is necked down
for no reason and the tolerances on the R's in and out of that are really tight, for no
F'n reason.
Somebody's nephew needed a job. And they can't trust them to do critical work, so they put them
on ground support. And they "OVER" engineer it.
I've done ag processing shafts that do more, and have more features, and "the print" sketch, had 10% of
the dimensions on it. This bearing has to go to the shoulder. This plate has to go to that shoulder,
this nut has to tighten on this other thing. This sprocket has to go to this shoulder, this gear has
to go to the other shoulder.
Thread(shoulder) reliefs are the most over toleranced bunch of shit I've ever seen in my life.
To be a "Good" engineer, how do you make the print look like you are earning your money on a simple
shaft. You add a ton of dimensions and a ton of detail and section views, and the only place you
can really do that is in the corners.
I'm looking at this print, and I just want to puke, I hate these F'n things. I'm not doing these
anymore, its just not worth it. I tried to price myself out of it, I really did, and its still
not worth it.
