ok that makes sense and where would i go about getting welding rods? and would this battery work 12V/1.3Ah Sealed Lead Acid Battery

I am not sure where in your area you could get welding rods, possibly from lowes, though don't quote me on that. there are other things you can use that will work and should be pretty easy to come by.

My first coil I used very small nails, just make sure that what you use is attracted to magnets, and doesn't hold the magnetic attraction after the magnet is taken away. to test this you can put a magnet up to the item you want to test, make sure it attracts, then once you take the magnet away, you can hold the item close to something else that is attracted and see if it attracts or not. if what you are using holds the magnetic energy for long, it wont work very well for a core.

Some other things you can try that i have read about are nails, things made of iron, coat hangers, electric fence line. there are lots of options, but the copper coated welding rods sound like they are the best. you can use ferrite core, but that would be a bit harder to find on short notice in my experience.

hope this helps

yes this helps i think that there is a welding place in a town nearby also on lowes website they have welding rods i think here is the name Lincoln Electric 1/8" Flux Coated Brazing Rod would these work?

yes your battery should work fine for demonstration.
you are going to have to cut the welding rods down to the length of your coil core, so don't get anything you can't cut easily or you will have a lot of time in cutting the rods. Lincoln r60 welding rods are what is recommended.

ok thanks ill get those tomorrow thanks for your help may need more later

Your battery is fine. Those rods are copper coated. I doubt you'll find R60 but R48 will work too. 1/16" are easier to cut but 1/8" can be cut half way with pliers and when you try to bend they will break easily. You may be able to get them in auto part supplier. They're 60 -70 cents each and 3' long. You'll need 3 - 4 of them to fill the core (depending on inner diameter of your spool).

ok so ive been working on this now and almost got the rotor finished i was wondering what side of the magnet on top of the coil i should use? like NORTH or SOUTH. also what wattage for my soldering gun should i use to solder the wires together?

Magnets should have their N pole facing coil.
25W iron will do. Get the solder with rosin core (not the metal/plumbing solder with acid paste!) Radio Shack has it. Also, it helps to have a piece of rosin. You can get small box from music store - rosin for bows(cheaper - better). Did you ever solder before?

ignore this post, i must have been writing my post while blackchisel97 posted his, we said nearly the exact same thing (great minds think alike, right? )
i guess timing is everything

ok and yes this is my first time soldering. also would lead free solder work?

Yes.
Make sure the enamel is well scraped off the coil wire ends. Twist bare ends of other connecting wires. Warm the wire with iron and touch with solder until flows over and creates a silver coating. Make sure solder remains shiny after cooling. Flat (not shiny) appearance may suggest overheated solder and result in so called "cold soldering" - poor and not good mechanical connection. If this happens it is better to warm up the spot and get the solder off by flicking the wire. Then, use some fresh solder and try again.

thanks ill make sure i do that when i go to solder this

Hey Kebob,

If your looking for welding rods try a plumbing specialist shop or wholesalers. I live in Ireland and things could go by a different name but could be the same thing. Ask for rods that are used for oxygen/acetylene welding. Copper brazing rods as plumbers call it over here. Maybe different where you are. That's what I have used and they seem to work fine. Does anyone know if they are the same a the rods Bedini specs ?

ok so i was wondering on the transister do i solder the wires to the metal wires sticking out of the tansistor pr to the blue at the base of the wires

What transistor did you get? Do you have your coil and rotor done?
