Re: [TCML] Primary Coil Copper Saving Idea



Hi Greg,

Yes, I certainly agree with you there. $100 for a 10# spool of magnet
wire of any guage is rediculous, especially now that the spot market
cost of copper has collapsed and I have refused to buy it myself  until
the prices come down to more reasonable levels.

Aren't you on the lower end of Mississippi? I am in the Memphis area
in TN, but very near the far NW end of MS. (about an hour from the
Tunica casinos).

Take care,
David Rieben

I've been patiently watching copper prices too, as I often squirrel away coiling stuff for the future. The fact that world copper prices have collapsed is only just now reaching Lowe's. My local Home Depot hasn't budged a bit on prices for copper or anything else--I've just about given up on them as a coiling source. Last year a 50' spool of 1/4" refrigeration tubing was about $50. At the time I also considered using thick THHN wire to save money, but it was so expensive, I couldn't see any cost advantage. These days that 50" spool of Cu toob is about $30 at my local Lowe's. I went ahead and bought one. I still miss the late 90's / early 00's when I could get it for $16-$18 per spool. Wish I'd bought a few and stashed them.

As far as Cu magnet wire...what's the deal? Has anyone found a rational price anywhere? I'm still living off my stash. $100 plus shipping for a 10 lb spool? Nuts! I'll give up coiling before I pay that.

Still money grubbing in Mississippi,

Greg

Raw and finished copper is WAY lower than it was just a few
short years ago. In fact, it's lower than it's been
in quite some time. We're stockpiling cable and
transformers like mad for several of our projects at work.
There's a real good chance that commodities will only go
up, as stimulus/pork (take your pick) money starts getting
spent. I don't think we'll hit the highs we saw just
a few years ago, but if you think you may want to buy
copper, now may be the time.
