They look pretty good Darren, but there are a couple things I would suggest.
Other than what Ed pointed out, I don't see any tolerances on critical dimensions. Without them there is no way for the machinist to know whether a hole can be drilled, or if it should be reamed for a press or slip fit on a dowel. The same goes for the slot in the first part. If it's for a key, then it should have a tolerance to ensure that the key will fit. Any external diameters should also be toleranced if they are to fit in a precision bore.
One of the two views on the nut drawing is incorrect, but the information is all there (except for the internal thread as Ed pointed out). Oh, and what is the size on the thru hole for the 1/8" pipe?
