I'm trying to replicate this on my machine. When you see your drop issue, your fine is feed engaged and the quill lock is not engaged? How are you producing the movement and where do you notice it? I did find something similar in the new manual. Do you think this is the same thing?
loose. I don't see it all of the time. The best explanation of what I feel when lowering the quill (only when lowering)
would be if the worm gear was missing a tooth and the quill dropped a small amount. I suppose it could also be
that the quill is catching on the set screw a bit and instead of the quill dropping smoothly it hangs a bit then
drops suddenly. Maybe there is a rough spot on the quill where the set screw rides?
The drop is not a huge amount, but it happens.
What I really need to do is to be much more methodical about characterizing this. I have marked where the
keyway is on the outside of hub #1, so I can raise the quill as high as it will go and record over multiple
tries where I encounter this drop (like the keyway mark is at 3 o'clock on the first revolution of the FF and
9 o'clock on the second.) Having this information might help identify if this seems like a gearing issue or
maybe it is an issue with the set screws...
I just need to find time to do this...
