Everybody seems to be clearing out their sheds. It must be the weather eh!!
I have been 'spring cleaning' mine and tidying up and sorting out. My scrap boxes were rather excessive so I went through them all, just like you, Roger, a lifetimes collection of shapes and materials, just for 'that' odd occasion.
I ended up with stuff my wife thought I would never use in a hundred years (very generous, I thought), so we sorted out a few boxes of metal here, wood there, plastic here, and enough electric wire to connect to the next town, to go to the local tip.
On arrival at said 'Tip', I was confronted by a 'Job's worth' who said "No trade waste' and don't come back again. It took a bit of persuasion to get the stuff in the skips.
Now, if only I could have actually sold the stuff, for what I'd paid for it. There's a thought.
