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?
