Hello everyone,

 

    While I was installing the indexing control system, I figured I would post some detailed photo's and a video of this awesome system in operation. If you don't have this system, I would suggest purchasing one for your turntable. There's so much that can be done with it,  what I'm showing in my video is just scratching the surface. I will explain as much as I can and what I learned, I will need Al to step in and explain the many other features the system has.

 
Thanks for looking,
Alex

  HERE'S PHOTO'S OF THE INSTALLATION
 
    HERE'S HOW IT LOOKS BEFORE THE INSTALLATION. FIRST UNBOLT THE MOTOR
     BRACKET. FOUR BOLTS AND IT COMES RIGHT OFF

   MAKE SURE GEAR TEETH AREN'T TO FAR APART OR TO CLOSE TOGETHER JUST SIGHT
   PLAY.

  DRILLED OUT

trains 3291

    SWITCH AND BRACKET INSTALLED THIS WILL HAVE TO BE ADJUSTED TO HIT THE HOME
    GEAR TAB.

  ALSO BEFORE TAKING ANYTHING APART YOU SHOULD TAPE YOUR DRIVE BELT INTO THE
  GROVES SO IT DOESN'T COME OUT. THIS IS VERY IMPORTANT. ONCE YOU INSTALLATION
 IS COMPLETE YOU CAN REMOVE THE DUCT TAPE

  NOW THE INSTALLATION IS COMPLETE,THIS INSTALL SHOULD TAKE ABOUT AN HOUR

Thanks for posting this Alex!  I will certainly be taking a look at this system at York.

 

A couple questions about the operation and video.  I noticed that all but once the video cut between the movement of the TT bridge and the movement of the engines.  In a couple of spots it looked like the bridge over shot the whisker track.  Did you have to adjust the alignment the alignment before making engine movements?  If so, what is the method for making subtle adjustments?  If the bridge overshoots, does the motor control automatically reverse and realign or is this handled manually?  I'm very interested in integrating turntable operations with layout automation, so I'm curious about the details of this system.

 

Al, does the system interface with TMCC for direct command control operation?  If not, are there other options (i.e. contact closure inputs) for integrating your indexer with command control?

Dave, I am sure it is an optical illusion. The quadrature encoder is accurate to a 64th of an inch on our 34" tables and even greater on our smaller tables like Alex's. 
  If so, what is the method for making subtle adjustments?  If the bridge overshoots, does the motor control automatically reverse and realign or is this handled manually?
All adjusting of bridge alignments to whisker tracks is done in setup and you can address bridge movements down to single encoder positions to achieve perfect alignment. Once the tracks are programmed the bridge automatically stops at that exact point every time. Also the bridge will rotate to selected track by the shortest route, plus you can select which end of the bridge you want to go to your destination whisker track.

Yes the indexer will interface with TMCC for direct command control. We have a board that piggybacks on our keypad board that does this. We are planning on having that at York to demo hopefully if all goes as planned

 

Good morning Al, Ben, and Dave

 

  Just to keep us all on the same page, the bridge lines up perfectly every time with each whisker track. It's the video quality that's making it look like that. We shot this video with an I phone holding it in our hands. I will shoot a close up video today of the bridge and the whisker tracks lining up. I can assure you they line up perfect. What screws up the video is editing it and putting it together, when I take video's today I will shoot separate video's each time with no cuts in it, of the bridge starting from the home track going to each whisker track.

 

Al, Ben want's to know if the system will work with other turntables?

 

Thanks,

Alex

I'll definitely be checking out the system with the TMCC piggyback set up at York. We currently control the TT with a DC Commander board, and it runs great with the Cab 1/2, but because it is not on the edge of the layout, it can be a bit difficult to eyeball the line up at each track.
