was that all four springs, individually compressed by 12mm to give 150kg force

Yes.

Feck, I miss measured the original length, they are 64mm long springs and not 67mm long, so its a 9mm compression for a 150kg force. Therefore a compression to 46mm would give the required 300kg force. I have edited my original post.

Also there are 8 springs, as I have 4 on each end.

I also tried to compress one of the springs in a vice and I got it down to 44mm which was almost full compression of the spring and it still expanded back to its original 64mm, so I know that 46mm would not be over stressing it.

check twice assemble once - or similar

My attempt at a picture of todays partial eclipse,



Also did the pinhole camera trick which worked better.



But it had some effect on my solar yield too, I reckon its cost me about 30p in less export.

At least you saw the sun, it has just recently put in an appearance up here, been seriously grey the rest of today!

Yep yesterday was more akin to a dismal December day than March, but today is already looking much much better !

I was wondering if someone would post a solar generation plot for the partial eclipse. This forum doesn't disappoint!

I used a pair of binoculars projecting onto a sheet to view it.
(I don't have a generation plot as I'd have to go up into the loft and take a photo of the inverter display for that)
