I have a L&R Mastermatic in desperate need of rewiring, especially the cable going to the motor. I removed the motor assembly an began to disassemble it, but have issues separating the upper and lower housing. I tried prying a bit, but stopped in fear of damaging the internals. One thing I noticed is the motor brushes did not fully come out and think possibly these are not allowing me to open the housing.  Does anyone have experience opening this particular L&R motor housing? Any pointers?

I had planned to make the NAWCC event in Mesquite early this month, but it just didnt work out.

Im new so I was not aware of the event. By the way... 

  1. How do I measure for baskets?
  2. Is the main center column tube on the base Nickle plated or Chrome plated? Going to send mine to be redone.

There was a large NAWCC regional in Mesquite.  People get together from all around and buy and sell their watch/clock stuff.  If you are not in NAWCC, you would not know about it.

Not sure what you mean by measuring baskets.  You should have an aluminum spinner that mounts on the end of the shaft.  The shaft, I am pretty sure, is just a steel rod...no coating.  Leave it alone.  The baskets mount on the spinner when you are ready to clean.  You don;t have any baskets?

My machine didn't come with any baskets. I need to find some of ebay, so was trying to figure out what diameter baskets i need. 

I meant the 1" main center pipe. I think it's nickel plated, because it somewhat yellowish after a slight polishing

      Stem removal after fitting hands

      By Neverenoughwatches · Posted

      So leave off the seconds. Stand the movement on its edge, its the dial edge that rests on the pad ( either rubber or cork , something that wont slip ). Use a finger of your left hand to hold the movement upright,  right hand presses the release and flicks out the stem. I do it this way so i can see what I'm under a microscope. But you could hold the movement between two fingers of your left hand, its the right that has to manipulate the stem out by pushing the release and flicking out the stem with  right ring finger nail. Sounds more complicated than it actually is. I guess you could fix a push pin to something solid, then all you need to do is push the release against the pin, leaving your right hand completely free to pull the stem out.

      Try putting everything back together and closing the back cover. I think one of the two springs has to contact the metal casing to ground the casing. So when you press the button, it will touch the contact on circuit board and close the circuit.

      Yes, the seconds hand is the longest and goes almost to the edge of the dial. I can’t quite picture it how you do it on the rubber pad

      A don't think so it leaked or damaged it because the watch itself works it just the buttons ain't working not connecting with the circuit board have taken more pictures of where the buttons makes contact with the circuit board.

      I think what peter means oh is once he has fitted the hands and  checked for  alignment if them and that they dont foul, how does he then hold the movement to remove the stem in order to case up. The dial cannot be laid on a cushion or in a movement holder as the hands will get damaged. This can be quite tricky for a beginner, what i do is  to stand the movement on edge on a rubber pad so it doesn't slip. Hold the top edge with one finger then my dominant hand uses 3 fingers to press the stem release and flick out the stem. See below peter, leave off the second hand as this is the longest and gets caught the most, then fit it once the stem is out. Alternatively place the movement in one of the cup style holders, i imagine this is what they are designed for. They only touch the very edge of the dial.
