I was watching a video and they mentioned binding the wires in a loco to keep them out of the drive. It was something about a waxy threadlike material that sticks together when you press it to hold the wires.
Any idea what they were talking about? I wish I were paying more attention before it got away from me.
Not familiar with anything that sticks together, but dental floss works fantastic for bundling up wires. We all have that package of floss that our dentist gave us...that we never use :)

I have used “Bees Wax” from craft stores in sewing department.

Slightly sticky helps string stay together.

Re: Wiring problem

Charles, disconnect the two output wires from the MRC unit. Then with power ON verify with a voltmeter that there is near zero volts across all 4 loop isolating gaps. If it is not zero you have an unwanted connection to loop tracks. Find and disconnect it.

This is typically referred to as cable lacing.

It’s called Stator Lacing and Tie Cord. In another life, we used it to bind rewound coils of wire for motor stators and armatures. It is a braided flat cord (cotton?) that was coated with wax, or something resembling wax. That was 45 years ago and I still have a partial spool of it. You could also wax your own thread with beeswax and get similar results.

HiTom,

You won't regret those changes. That's a lot more reasonable while still giving you lots of options. Like it!

Better....
Tom,

Run some of the Green Track...while also making an attempt to run the Roundtable.
On the way to doing this...
Consider some Structures and Scenery as well as spacing.
I expect a few more epiphanies along the way.

power supply for servos?

Dave Emery
 

If I go with servo-based switch machines (e.g. Tam Valley or Walthers), how do I power them? It would be a pain in the posterior to have to provision AC and then a bunch of wall-warts around the layout. Has anyone done a ’servo power bus’?

 Dave, I have a 12 V DC power bus that runs around my layout. Then use small adjustable regulators from Banggood.com set to 5 V to power my servos.

Hi!
You power both systems from the DCC Bus or a 12v supply.
The control boards supply the power to the servos.

A friend of mine uses a different approach to keeping wires out of the motor of a locomotive.  He uses Aleene's Tack-It  Over and Over.  You can use the adhesive to hold down wires and you can peel them up and move them later.  I've seen him use this stuff.  Appears to be a good idea if it holds up over the years.  You can get this adhesive at craft stores.

Walthers makes a 12v PS {filtered} to go with their new LCC switch control;.

As updated there are no reversing loops except for the turntable itself.

Hi Don,

Are the turntables always in need of an auto reverser by default?

Thanks,
Tom

Hi Tom:

We added reversing cam switches to the turntable shaft. They work OK, but there is a dead space where we have no tracks.

You can also use a toggle switch and correct the polarity manually.

Turntables need a reverser only when they actually turn the loco around to head in the other direction.

Inside the pit there is a circle of track. It consists of two almost semi-circles with two small insulated sections, the size of the bridge,  opposite each other, in an unused area. 
Each semi is powered as opposite rails on the feed track, when the table rotates each semi powers each pickup at either end, it crosses the dead zone, and reverses as it reaches the powered rails.

Hello Don:

Cool! That works too.

I don't need a reverser on my turntable, I'm 3 rail "O" gauge!

One circuit is the gear motor, the other is the Lazy Susan bearing.

Re: power supply for servos?

 

I use a separate 5V bus for my servos turnout controllers.  I currently
have about about ten installed.  I drive my bus with a switching power
supply.  Jameco probably has the best US prices.  I got mine via Alibaba
Express.  I wound up getting one with considerably higher Amperage
rating then you would think because of start up issues.  Normally the
servos use very little current to run but when first powered on they can
draw significantly more to get to the exact position currently
commanded.  At power up they all did this at the same time.  Sensitivity
to this issues is likely dependent on the servo driver.  I have been
using Pololu USB programmable drivers because of versatility.  However
they did not have an option to delay startup on individual servos.  I am
using a 5 Ampere supply currently.

The failure to start up properly was pretty catastrophic for me as it
led to bent wires at my servos.  Since getting a much bigger supply I
have had zero problems.  It would be interesting to know how the other
stuff out there behaves.  I am going to try the Swedish Möllehem
controllers going forward.  The pricing and delivery to the US was
excellent, they seem to be well made and they interface to Loconet which
are all priorities for me.  It will likely be a couple of months before
I actually install my first one.
