I have an Incra drill press table that's been on for over 20 years. Pretty much identical to the one in Glenn's photos. I use it quite frequently, for all manner of tasks, not just wood working.
It takes less than 5 minutes to remove it if I need to do the things that Matthias is doing in the link.
The crank handle extension is a 1/2" drive ratchet, extension, and socket, that cost less than a dollar at a flea market.
I am looking for new drill press, an the table will be installed on the new one. They're to convenient for most wood working tasks.
