At my last place, the walls were covered in flat faced kitchen wall cupboards, and the one near the lathe and Bridgeport got a coat of blackboard paint - very handy to mark down measurements or notes when working.
New place (well not so new now I've been here 8 years!) again lined with kitchen wall cupboards, but no use for use as a blackboard as they are 'plank effect'. So I made up a bit of 19 mm chipboard, gave it several coats of blackboard paint, fixed 4 very powerful rare earth magnets on the back, and stuck it on the metal doors of the Beaver Partsmaster CNC Mill. Nice and convenient for the Bridgeport and lathe.
Yes but - it started slipping down the door
I added another set of magnets but again it would slowly slip down the door
Well it's been kicking around unused for probably four years - propped against various things - constantly having to be shifted. Well I'm on 'light duties' at the moment, so an enforced period of not doing much has triggered loads of mooching about in the workshop plotting, scheming, and tidying up. And I kept tripping over this blackboard - then it dawned on me - bend up a bit of galvanised sheet to act as a 'top hook', incorporate a shallow shelf for chalk and rubber, and not only will it be usable, but I can stop tripping over the bally thing
... so a few folds in the Edwards folder, a few screws into the chipboard through the bent bit and hooray - it works
Not a huge achievement but at least I've done something other than
.... now where is that box of chalk sticks - I KNOW that I have it somewhere ....
