Oh dear, I’m at it again – I seem to like fiddly repetitive tasks
Needing a bit of mesh of some sort for the flywheel cover and not having anything to hand I decided to have a go at making something. Looking at the photos I think the original was perforated plate, so drill lots of holes in a bit of plasticard and Bob’s your uncle:
Mark out the pattern by scribing, then drill pilot holes with a 0.6mm drill bit:
Enlarge the holes with progressively larger bits then a tapered burr, then cut out and try in place:
Woo-hoo, the flywheel is visible through the holes
Yes, I Gnow I could have ordered some brass mesh from somewhere but I like doing this sort of thing and it’s probably easier to do than it sounds. The only tricky bit was marking out the centres reasonably accurately, once the pilot holes were drilled enlarging them was easy – a quick twirl of a drill bit in the fingers is enough, 'tis very thin plasticard.
