Ok I should learn to read. If it never gets too tight but slips constantly then there is something wrong with the threads somewhere.
One thought would be that you don't have enough threads on your fork and all the stress is taken by a few threads on the locknut, which may have failed. Pull the locknut off and look at the the fork threads and the locknut threads. Striped threads should be obvious.
Also check you have a situation like in the diagram below. You want as much of the locknut to thread on to the fork column as possible while still leaving a gap.
I'll leave my original post in just case and so I can be mocked.
I bet you need a spacer under the locknut.
The top locknut is probably bottoming out on the top of the fork so while it gets tight, its not not actually contacting the cup/cone together and so everything is still loose.
Pull your stem out. There should be a small gap between the top of the fork and the locknut.
See attached picture for what it should look like. Read the text at:
