Nice find Jack. This plays into my debate about eventually doing this type of joinery on the bot, but where to locate the clamping area. It is commonly done on far end of machine as demonstrated by many others here, but I've been considering utilizing a setup like the video shows on the lesser used 12" of my 60" bed. This would allow me to stay on what now is the normal operating end of my table, avoiding more cabling issues and moving monitors, etc. Just need to figure a way to plug the hole shut for the occasions that I need the full 60" table width. Since I'm set up with vac already, may be best to work on that far end and avoid creating integrity issues with the table and vac.
Appreciate the food for thought.
