Electric motors question

So yesterday I finally came back from work before dark and proceeded to take the motor apart.
I laid the pieces down in order then I got to the permanent magnet and I flipped it before setting down so I don't forget.
I took the front parts off the shaft so it wasn't too hard to put the brushes back on the rotor.
As I am assembling it back together I flipped the magnets, :doah:.
I try it, and it's still backwards.
WTF.
So I take it apart again and inspect it carefully, there's traces of rust to show where it matched on the side and sure enough it was upside down, that is when I realized what I had done, a double negative...
Anyway put it together and it works great and seems to go better now that the brushes are kept tight on the rotor.
Pictures might not be in order.

:woot: :waytogo:

That would’ve been funny had you not caught your mistake and came back to say that didn’t help. :haha:

Well, I will not say that never happens because then it will, but in general I figure out what I did wrong by tracing back in my mind what I did and what my thought process was.
If you noticed when I first asked about this, I had 6 follow up questions about what I thought might have happened.
I do very well with thinking outloud and this place is the best place to do it.
 
So you’re saying we’re like a wall and you bounce things off of us. :whistle:

Just glad you got it fixed. Always good to hear a success story.

Well the advantage here is when I run out of ideas to bounce off of you guys you start bouncing ideas off of me :pimp:
 
Glad you figured it out..first time rust actually was useful!..
Looks like its a bitch to get the brushes over the commutator while assembling the motor too..

I've done similar things before---after spending a whole day trying to make an Briggs & Stratton engine run on a wood chipper A friend brought me to get running--I finally figured out why it still had no spark,after I put a known good coil on it--that I had the coil flipped 180 degrees,so the spark plug wire was facing the cylinder,not the blower housing..yes,it matters!..:doah:...o_0...guess I need to watch what I'm doing better..:blush:

My friend watching me most of the day get more pissed off as I cleaned the points,made sure the plunger was opening & closing them (which requires pulling off the flywheel !),and checking a bunch of other things,and hours passed--he said :
"Gee Bob--next time maybe you should smoke a joint or guzzle a few beers down first--then at least you'd have that to blame your mistakes on!"..:unsure:

The other day I went to use my garden tractor--it usually fires up on the first or second pull..this time I pulled the rope about 20 times,then I took out the spark plug,thinking maybe I had the kill switch in the "off" position...nope--it had great spark...after 20 more pulls,I had to stop and let myself recover before I had a heart attack..
Then as I'm sitting there,I look at the fuel shut off valve and DUHHH--it was OFF..:doah:..turned it on,it fired right up on the first pull..:surepal:

I swear I get stupider by the day..I put that valve on there,and always turned it on first thing..:screwy:...I tend to "misplace" things a lot more often too...sometimes I find them right where I left them--other days they remain among the missing until days,weeks,or months later,I go looking for something else,and the missing object appears ..

I’ve done that before ... more than once. :doah:
Pulled that damn cord for a half an hour. Then after I got it to run briefly with starting fluid I figured it out. Now that I took the protective guard off of the pull cord housing (and removed the pull cord) I can start it using my cordless drill with a socket on the end. Don’t dread starting the mower anymore.
 
I've been told that there's something that's the first to go the older we become, but I forget what it is...
 
If it makes you feel any better, I didn't realize how right my parents were about life until I was in my 30's. And every year after that, I find more stuff they were right about. Continue to teach them the right way, they are learning even though they may not know it for a few more years. As long as they aren't telling you they want to go to Portland to express themselves, you're ok!
