As much as I cherish every blessed piece that came with my X3, it
really sucks getting out the spanner to hold the quill while loosening
the drawbar.

How could a spindle lock be mounted to the top cover? I think
somewhat like the lock on a Bridgeport head. Mount a eccentric cam up
there to engage the spindle? Have it spring loaded so it won't just
drift into the spindle while it's rotating (wow, a roughing mill at
work, just at the wrong end!).

Comments, derision, advise, disbelief?
