Ahh, sorry, didn’t read that project plans was related to WOODWORK. However, I’ve just had my delightfully precocious grand-daughter Evie with me today (just coming 8 and going on 28). It’s SHE who has ‘plans’, though it does take a bit of time for her to decide whether it’ll be a mobile phone or a tree-house that ‘we’ are going to make in the 5 hours she’s here. Talk about the back of a fag-packet (not that I smoke) job … it’s all too often blind trial and error. Today, however, it ended up being a ‘Fidget-Spinner’ made from some circular pieces of marine ply cut outs, some mild steel sheet cut into small rectangles, smoothed and screwed onto the circle - set at 120 degrees to each other.
Then to make a ‘bearing’ on which it could spin she discovered a piece of copper tube which was cut to length and forced into the centre hole using my elderly arbor press. After which she cleaned up the bore using a chain-saw file, before finding (in my copious junk box) a long rolled-thread screw and a couple of nuts which were locked together … !
‘Hey presto’_ we have the planned fidget-spinner. Apologies that wood was barely mentioned!
