Note to self...and others as silly as me

Never try and cut MDF with a jigsaw when the MDF isn't clamped down, luckily I still have all my fingers but it got pretty close. Also wear a dust mask and safety glasses, otherwise you WILL get large MDF pieces in your eyes and lungs (or throat if you swallowed some like me...don't ask how I managed that).
Never forget those dreaded words...Health And Safety.
