Had a very similar experience just yesterday; with the shed being in a semi-permanent "state of transience" none of my tools are set up properly yet, as they're constantly being packed/unpacked and moved around.
I was making a replacement side for a flatpak drawer, with a mitred end instead of dovies. (I did say 'twas a flatpak. :rolleyes:) Not being concerned about quality or perfect fit, instead of wasting time setting up the TS to cut the mitre I just used my li'l Ryobi Linisher to sand the end to 45°.
Had just about finished and was re-introducing the piece after checking my marks, when I fumbled. The wood, being large enough to hold comfortably, didn't go flying across the room. :no: Instead, the linisher launched itself off the top of the boxes I'd set it up on. :doh:
Bent the table out of true and I'm not game to open the box it landed on to check for damages... I think it may contain some of SWMBOs "ornamental doodads."
Fortunately, no harm to me beyond bruised pride... but that may change if 'Er Indoors finds out. :C
