Scrap? No. New to me.
I cut the original motor-plinth from the back of my Harrison lathe cabinet as it made the machine stand a wasteful foot away from the wall, in a workshop already tight for space. The new 3ph motor, physically smaller than the 1ph motor it replaced, is on a frame above the headstock, where it's also clear of dust and dirt around the floor. I had to modify the guard to suit.
I didn't throw the welded-steel box away, not with a lot of 5/8-, 1/2 and 1/8- inch plate on it, though it took a fair number of 4.5 inch cutting discs to dismantle.
One of the thick bits is earmarked for my wagon con-rods, the thin bits have supplied material for the wagon and the workshop hoist. A small off-cut picked up from the floor became a washer for a bolt clamping work to an angle-plate.
A manual winch I built for a cave-digging project on Mendip uses a fabricated PVC drum thrown out at work (a left-over from something), between hexagonal frames I welded (well, very-hot-glued) from old miniature-railway rails that looked as if they'd been dragged through a hedge backwards then left there – as they had, for a couple of years in fact.
There's something satisfying in finding a tatty, heavily-rusted old steel bar or plate has decent steel inside it waiting to be let out and put to new use. As long as it's easier to machine than some old cable-drum tie-rods I have in stock.
The only new-to-me items I've really had to abandon hope on, were a cast-iron sash-weight so hard it even defeated a heavy hacksawing machine at work, a bit of architectural cast-iron that was free-cutting but with blow-holes reminding me of a pikelet, and a half-shaft too hard even for a carbide tip.
Actually I tell a lie… I recall now the cast-iron pikelet was useless for a piston but fine for the heavy inner part of the lid on my steam-wagon's vertical ' stoking-shoot ', as the original was described.
