The Jigsaw Massager
Up until today, I didn't even know that there was a "Not Liable" category to Instructables. That makes me so happy.
And now you can probably see why it's called that. This is the Jigsaw Massager. Just remove the cutty parts and replace them with thumpy parts, and you now have your very own power tool massager. Now you can have some relaxing foreplay before pulling out your drilldo.
