New comer needs any and all help

Yea I been on that site before. Thanks for all that info but I think your a bit ahead of me ha. Yesterday I got lazy and didn't do anything.  Today I'm going to work on the circuit. But let me just be clear..and make sure I've got this right. Now the two wires that are on the bottom of the coil or beginning of the coil one goes to the base and one goes to positive battery post.
Then the two wires at top of the coil or the wires that are the end of the coil. I goes to the collector and one goes to negative buss right?

The coil has one thick wire winding and one thin wire winding, right? Top and bottom make no sense to me, all my wires come out one end of the coil. Start and finish make more sense, but even that doesn't really matter much.

The thick wire is the drive coil and the thin wire is the sense coil.

One wire from the THICK wire coil goes to the battery postive terminal  and no where else.
The other wire from the THICK wire coil goes to the transistor collector.

One wire from the THIN wire coil goes to the transistor BASE resistor and thru that to the Base. The other wire from the THIN coil goes to the transistor EMITTER which is also connected to the negative battery terminal.

If the motor does not run and you see NO CURRENT on your milliammeter when you try to spin it to start, try reversing the THIN coil wires only. You should see 10 or 20 milliAmps when the coil fires if the wiring is correct, even if the motor doesn't startup and run.

There are four possible ways to connect the two coils. Two will work and two will not. Of the two that do work, one might work slightly better. Once you have found one of the ways that works, to get to the other way that works you reverse the polarities of BOTH coils. But the thin wire coil always goes between emitter to base resistor, and the thick wire coil always goes between battery positive to collector.

To charge another battery, it goes like this:   Collector > diode anode, diode cathode > charge battery positive, charge battery negative > main circuit battery positive.

OK I got ya.. yea I should have said start and finish I guess

Very nice video.. good job.
Where did u get the bearing and shaft for your rotor?
