Thread: Electric Motor

yah its best to know a few tricks.
for bright coloured stripped cable and bus bars that look clean .they call it millburry. they give me $6.20 a kilo
if there is soldered joins or any fitting it knocks about $1 of the price. in some places $2 its best to ask how they have grades it.
I had some silver plated copper bar and fittings and if that was included in the haul it would knock the price down a couple of bucks.
because its plated.
so i save that separate.

I was aware that stripped copper is worth more than insulated copper, which is only fair. I was not aware of any other distinctions, but then that does not mean much at all. There is a shortage of scrappies in my area.

Depending on where you live, melting it out may not be an option, though it certainly works. The chisel idea sure sounds easy enough for the odd motor.

I there was talk here of making scrappies pay the same for insulated copper as stripped/burnt, to stop people burning the insulation off. (though I don't know if it has happened or how it works if it has?)

The same applies to scrap stainless. Two price grades. Clean stainless and dirty stainless. I recently took a dismantled commercial kichen from an old nursing home to scrap metal place (for a charitable organisation that has helped us in the past) and they charge a different rate if its dirty, stained, oxidised or has non stainless fixings still attached. Same with alluminium. It only requires one ms screw or bolt and it reverts back to "dirty" rates which can be a substantial reduction for a few hundrex kilos!

Hi Dean, Guys,

I imagine there are different rules in different places ! Here my local scrappy has a chalk board labelled "Today's Prices" on it the price for the different metals, including car batteries are written. I've been there when someone has phoned and asked "What is today's price" and he just quotes what is on the board. Now he does vary the price when for instance someone brings in mixed materials.

But your right there is a big leeway for interpretation.

One of the problems here in the UK, don't know about elsewhere, is thieves !
It seems that a lot of the copper cable that is stolen is burnt off to remove the insulation and thus its identity. Regulations, slow to be applied, now require that all persons bringing in scrap are required to prove their identity and any payments are only paid by cheque. Cash payments are no longer allowed. In addition the person bringing in the scrap is photographed and the vehicle ID number is recorded. This however doesn't prevent unlicensed scrap yards operating. I'd be willing to bet that these unscrupulous ones really gouge heavily. All that said it still hasn't stopped copper theft, and the recent loss of life associated with it !
I mean how on earth do you steal 600 meters of 11 Kv 3 phase line without being noticed !

Scrap dealers have got it all their own way, all it takes is one small steel self tapper in a piece of alloy and they downgrade the lot if you don't notice it. Clean bright copper gets top price. Up here the hint of tarnish on your copper and its downgraded. All I can say is when it gets to its destination its probably tarnished from the salt air. Took a load of alloy gearboxes and steel to them, which had been cleaned of all ferrous metal which I got the right price for and the rest in the back of the ute was just a guess on the weight. I think they had a win there on that one. LOL

Talking of all this i have a 1.5kw dc motor ive been thinking of scraping.
It is really quote heavy and a big motot for 1.5 kw.

Aaron, your mailbox is full again....
Do you want me to post the lathe saddle guide back?
Also, do you want the big old 2hp motor for your Deckel?
