the Best Scavenged items ARE the things you end up using,
Other wise it is normally scrap iron or junk, probably my best score on scavenging things is my welding truck,
a before or soon after I got it, the pick up was freebie, originally my son was looking for a dully axel and one guy in town had this truck setting kind of behind his shop, so I asked if he would part it or sell it, and he said it is your if you want it, I said ok, when we have a trailer in town I will pick it up, he said why it runs, and still has plates and insurance on it, for a few weeks, so I got in it and it starts and I drove it home, and decided my son could fine axles else where, (it would not be a good truck for a 50 mile drive ever day, but great for around the farm and a once in a while trip to town.
after clean up
I found the Lincoln welder for $500 and works well, a lot of hours on it but it seems to have been well cared for,
I have since added an air compressor on it, the compressor was made out of used parts the tank was off a compressor the head went bad on, the pump off one that the tank had rotted out, the motor and the controls were mostly new, I have since added hose reel on the truck as well, and 50 of hose, for the fencing of the farm I have some air powered post drivers for rod posts and T posts, as well as keeping tires up and it will run other air tools, I added a go cart clutch to the compressor so when starting and when it is running but full the pump is not running, it has a unloaded valve and throttle control,
I salvage a lot of things but I also went threw a few years ago and let a scrap man take a lot, that was old and obsolete, (If I can not find parts for it any more why would I want to build any thing out of it?) as if some thing does break it back to a total rebuild,
