I think I may have messed up with my wire order. I ordered 22awg and 26awg. They just got here and I think they are way to thick. What gage wire should I order? Can I do anything with the 22 and 26?
"Energy can not be created nor distroyed, it can only be changed into other forms" - so lets do some changing! "Every Action has an equal and opposite re-action" - Why not use the re-action to create an additional action?
Thx comwarrior! I printed out that chart for future reference.
I re-watched Daftmans video about building the coil. In it he says about winding it 500 turns. Then he says the turns aren't important the ohms are. What should the ohms be? I have noticed that alot of people are puting 800 or so winds, should I go with 800 over 500?
Micah, Good question! I have been trying to find the Ohms numbers I have heard about too. Must be in one of the books I have not purchased yet. Hope someone has this answer.

Well I will attempt to answer your question from a base of testing hundreds of coils and reading vast amounts of data and yes more testing. Here is the best answer I can provide to your question on Ohms.:
The impedance of free space is 377 ( 376.730313462 ) ohms per coil wrapping.
However (Yes however) the most important things you need to worry about in your coil is the number of wrappings and the core make up. IE the size relation of the core to the magnets you are using to the amount of magnetism you will need to achieve the speed you are looking for.
Yes ohms are very important as well so here is the total answer to your question.
Windings are to be 175 to 200 per wire or 500 turns.
Core is to be 1/2 the size of your magnets, (core make up see my post Differences in cores)
Ohms can be 360 to 450 for a 12 volt system
Wire size: should be min 2 same size and the 3rd is to be 1/2 the size of the 2.
Wrapping / coiling in a flat or twisted pattern all wires at same time from one end of spool to the other.
Verify the N or S for your coil when pulsation is happening. should attract your rotor when engagement happens.
Basic I know but it is the full answer to your question.
