Hi everyone, can anyone tell me what will happen if I use a coil core that is 3/32 dia copper coated steel, will it destroy my other components as they are all what the plan called for and I don't want to do that ha ha. I don't know what the wire is except it is copper coated and is hard to cut. It was near the same dia. and copper coated so I used it (dumb me ) but I can replace it if it is a problem. I didn't know steel could be a problem until I visited this forum. Thanks Jim P.S. everything else is what the plans called for but am waiting for magnets and transistor (they are in the mail ) Thanks again for any help.

@mallard,
Just make sure it is magnetic. If it is, it should work. There is no danger to your other components, just to the success of your build. I have used 1/16 to 5/32 wire with success. John recommends 1/16. Some of the copper coated weldng wire out there is some alloy that is not magnetic. This will not work.
RandyImagination can take you to places of new posibilities. Without it, you go where others tell you as you know no difference. -
Randy you just made my day as it is magnetic, in fact it seems more attracted to a magnet than other metal of the same size ?? Thanks and I'm sure when I get the magnets and transistor and go to fire it up I'll have more questions ha ha. Thanks AgainComment

Hey guys
Im building for the first time.
Working on the core.
Im a little unsure, do I need to scrap off the outer layer of the welding rods or not?
I found these rods for sale with the specifications by Lindemann and Marukami (pg 60, Bedini SG: the complete beginners handbook)
Weldcote Metals R45 1/16" X 36" Gas Welding Rod 1# on eBay!
Welding Rod 1/16 Inch Diameter 3 lb
Please confirm this is what I need.
Kind RegardsComment

all the welding rods ive seen ppl use seem to come with no outer layer on themOriginally posted by ScientistG View PostComment

Hello,Originally posted by mallard8146 View Post
the corematrial is very important,the size of the rods is not so critical but the material.You need a material that is strong atracted to a magnet but if you put the magnet away the rod may not stay magnetized like ordinary steel does.You live in America why don't you buy the Lincoln R60.Don't make Experiments with this things.Built it like JB says and when you reach a COP over one you can experiment with other material.Comment

The key to the core is that it needs to become magnetic quickly but it
also needs to shed that magnetism equally quickly.
Steel does NOT do this.
Welding rods, type R60, are good and so is iron although this is very
hard to get hold of.Comment

HI all, I've found out the core material does make a big difference. Use no steel. Go to Lowes and get some of that green plastic coated (about a foot tall) garden fence, cut the plastic off and it is about 1/16 dia and works great as it has made a drastic change (for the better).That is only if you can't get the right material, this is very close. Changed to 850 winds changed the core and everything else but my wheel is as called for. Very pleased with the results.

all of those welding rods, are gas welding rods. they have minute differences in trace minerals (manganese, titanium, nickel, etc) for different materials. I have used r 60 r40 r45 and some others. the common denominator is they are gas welding rods to weld mild steel and iron. not brazing rod........Originally posted by wrtner View Post

Yes, but the bottom line is: Which of these three standards magnetises fastest and shreds magnetism fastest?Originally posted by Tom C View Post
They are probably the same price. If we go out and buy, we should get the best.Comment

I have used all 3.... zero difference in performance, it was just what the welding store had in stock at the time.Originally posted by wrtner View Post

Dear Tom C
Could you please help clarify the welding rod saga.
It has been said multiple times that iron not steel is to be used for the core.
It has also been said that GAS welding rods is the key and that ethier R45 or R60 can be used.
However If we look at a site selling the aformentioned description:
Weldcote Metals R45 1 16" x 36" Gas Welding Rod 1 Lb | eBay
We find that the chemical compoition of the R45 gas welding rod is that of steel. It doesnt even contain iron.
SO what is going on here? and where can I find ''iron'' rods?
In addition if you have any idea on how much (ie pounds or whatever weight unit you know) I need to order that will be greatly appreciated.
Furthermore I would like to highlight that lincoln do not make R60 or R45 anymore.
PLease clearly delinate the answers and solution

Filler Metals OnLine - Classification details
here is a listing of the rod specs and a list of manufaturers. R60 is a mild steel rod, copper coated or bare, you can get it either way. if you get bare then coat each rod with a bit of laquer before cutting. the rods break up eddy currents in the core because they are not a solid piece, and therefore do not retain magnetism.

rust
You can also get them wet, and let them rust for a week or so, and the rust will insulate them from each other.......Originally posted by Tom C View PostComment
