So last week I made three trips to the scrap yard...I made a deal with my boss over a pile of autobody scrap (heavy metal bumpers, crash bars from the plastic ones, fenders, doors, and hoods)...basically i can haul it to the scrap yard if i do it on my time...awesome deal...lots of sweat a little blood and time...free money for me...and his private junk yard gets a little cleaning...everyone wins...Here is the lesson part...and im not even sure what i have learned...maybe you guys can shed some light for me...Three trips...540 lbs...740 lbs...840 lbs...same pile of stuff...visited the yard on different days and at different times...first trip of 540 lbs was graded as "no. 2 steel" and i got about 40 dollars..the second trip of 740 lbs was graded "no. 2 unprepared steel" and I was given 46 dollars...then the third trip my haul of 840 lbs was graded as "tin" giving me a massive 14 dollars...I figured ok the first and second trips were a kick in the pants...no big deal prices are down a bit...but the third trip I considered a bit of a waste of time...I talked with the owner of the yard...apparently since he was wearing clean clothes and not sweating he was better versed on what the composition of a car body is...his exact words were "well the first two trips should have been graded as tin"..."because that is what a vehicle is made of"..........to which i reply "ok" (after a calm explanation of what exactly tin is and how much of a vehicle is actually "tin")...tin is a metal in and of itself...car bodies are electroplated with tin because it helps with corrosion...the weight of a vehicle comes from the steel that it is made of...am I wrong here?...or have I just been living a lie...fixing and painting vehicles for about 5 years now...?...someone please set me on the correct path here...ok so there is my sob story...im going to take all of my business to the only other yard for 50 miles...sigh.
