Garages that actually repair cars usually have left over parts. There was a garage in town that usually had several older cars parked beside the building for a couple of days. I stopped in and explained that I was looking for solid metal parts that had not been hauled off. He ask if I was a junker and I said no, a blacksmith, I acutally use the stuff. He didn't have much but I was welcome to the following.
Bent steering linkage from a Chevy truck, brake drum and a section of 3/4 round bar.
Feeling good from the first find, I stopped at another garage on the way home. It had changed managment several weeks earlier, and I had no idea who owned the place. Met the new owner and he just enjoys working on cars, turning wrenches, and does custom work. Said he did not have much but I was welcome to the following:
Car jack, U bolts, bearing race, tow bar with a trailer ball, idler pulley, wheel hup, broken crescent wrench, and another steering linkage. Then he said he had one heavy chunk of metal over in the corner of the garage. I should take it to get it out of his way.
One 2" or larger bearing block.
So, it can be done, but now I have to come up with an idea where I can use the stuff.
