What would you take first ?? Please help me with advice

The drive gears in some industrial mixers and dishwashers are brass, and weigh up to 10 lbs a piece.
If they are in good shape resale will bring you much better money and shipping can be done from home.

Just scrap?? Well then I would take the brass and bronze and let the folks at the yard figure it out. My uneducated guess is they are most likely brass. I my experience bronze is used on boats, but that is my experience.

I would hold onto the boards until you have place to sell them. Perhaps bring a couple of the boards and see if the scrap yard will buy them and for how much. 73, Mike

Take all the copper brass and bronze definitely. Brass tends to be yellow. Copper can range from orange (new) to brown or even green with age. Bronze will be in between yellow (brass) and copper (orange) in color. I doubt you will have bronze there. It is used alot in old door knobs, and statues or plaques that would be installed outside.

if you are doing the backpack method, concentrate on non magnetic first.

get us some pics of the electric boards they commonly toss

You can ship the boards to buyers on the buyer forum and they will pay you better than the scrap yards I encounter, if they even buy them. If you have that heat gun to take off board parts, you could even accumulate IC Chips, tantalum capacitors and gold pins seperately and get top dollar! With boards you can make serious dough if you have the capability to remove the components with ease.

Obviously any copper and copper alloys, wires for sure, aluminum.

Your backpack must contain at least the following tools to assist you if you need to break something down on the fly between breaks or to make space.
#1 and #2 phillips screwdrivers. Flathead screwdriver, diagonal pliers, File for finding the true metal underneath various painted or electroplated metals, a multi-set fold out hex AND star keys, and the obvious magnet. You can save space by bringing an cordless electric drill and a small black box of 100 various size and type of bits. The drawback is though with all that moving aroudn your bits wil constantly get messy and shuffled around.

You should also network with somebody either who lives close to you, or close by your job. If you find another scrapper, you can work a deal where he can help you haul larger loads after you have processed for your colored metals and escrap. So if its a stove, or a pc or whatever you can take out the control boards and wires and even small motors if anything as well as various alloys of copper and they he can get the tower or the rest of the stove etc.. etc..

Just brainstorming here. Do not hesitate to seek out assistance, we scrappers are just as know for our cooperation as our competitiveness.

I forgot to add a good pair of vice grips certainly comes in handy when dealing with appliances involved with plumbing or piping. I like to have two to get the best grips on the most stubborn corroded fittings.
