Re: Disrict Buss

Hi:

I have 10 districts powered by 6 Digitrax boosters. They didn't play nice until I totally isolated each district. I don't know what is "code" but this has worked for me. Plus the totally isolated districts make trouble shooting easier. Plus all lines to the rails are protected by circuit breakers, that do trip when needed.

There is two question that actually never gets answered or if it does they don't use my lingo, or it just flies over my pee wee brain. Here goes the question. If you break your layout into districts do you need to run a separate buss wire for that district? 

I am using a NCE starter set with the power cab. It puts out two amps max. However there is only one slot to tie in your buss wire. So the second question would be (if the answer is yes, you need another buss for another district) where does the other buss wire get tied inn. 

My layout is a 10 x 10 with hopes to increase the size. At this point only running two locomotives.

Greg,
To get your schematics and other images into the Group you will need to create a folder and then upload to your new folder.

How: click on the “View/Reply Online” item below. Then select “Photos” on the left side of the screen; create a folder with a short descriptive name - your first and last name, or project name will suffice. Upload your images and schematics into the folder. Then post a message stating you’ve done this and the name of your folder.

Cheers,
Dave

Re: Disrict Buss

My brother I use NCE (15amps) and have 6 districts. Each district has its own buss line tied to a circuit breaker.

 I recommend the following: from the NCE command station track connection go directly to a wire splitter which allows you to send a power supply + and neg - to a circuit breaker for each district. Total 2 circuit breakers. 

 From the circuit breaker send your buss line ( + and - use minimum 14ga wire) out for each power district, make sure you allow for several track drops to each district.  

Hope I helped.

Hi Greg,

Thanks for your reply.

The DC/DCC detector sounds very interesting. I would certainly be interested in more details and seeing a diagram.

I think there is a simpler solution to this (potential) problem.  install a
DC/DCC detector in the power to the crossover turnouts.  When the current
on both (mainlines?  Whatever!!) matches, the turnouts operate.  If the
current is different, they won't.  These detectors work on a single track
also.  Just put a 2' section of track between the two that can have DC or
DCC, and the track goes dead if the current sources don't match.  We have
been using these detectors on our large HO club layout for 8 years + with
no problems.  The two guys who designed and constructed these detectors are
both gone, but we have the wiring diagrams and component lists to make
them.  Circuit board is about 4" x 6".   Not hard to do.  We did a clinic
on these at the Indy NMRA show in 2016.  If you'd like more info, or to see

Re: wire strippers

 

I pretty much do the same thing as you but use bare copper grounding
wire in what is essentially a knob and tube system.   No need to strip. 
I use nylon cable clamps to keep the wires separated.

Hi Allan,

Thanks for your reply.

Tam Valley market the Dual Frog Juicer as an auto reverser.  Their documentation says "This board can be configured to use as an automatic polarity reverser for two frogs, a reversing loop, a turntable, a wye, or a crossing."  A jumper is used to connect 2 pins to use as an auto reverser.

I am using 2 Dual Frog Juicers as auto reversers on my home layout and they do a good job. This layout is DCC only and will never be exposed to DC.

I contacted Tam Valley. Their reply was: 

"Many people have used the frog juicers with DCC and DC on a layout and no one has had any units go bad.
So it is safe to do."

As many people have used them on both DCC and DC I thought there may be some on this list who could give me the benefit of their experience.

I know it will not reverse polarity with DC but wondered if it would allow the DC power to pass through as if was not there. Maybe I need a follow up email to Tam Valley.

My young grandson was very disappointed that I could not take my home layout to a exhibition my club held recently. The new layout is being built as a result of that and to some extent is experimental and I'm trying some things I have not done before.

Cheers,

John Heaps,

Have you contacted Tam Valley and asked them?  You are planning to use the Frog Juicer in a layout in a way it wasn't intended.  I don't want to guess and be wrong.

I thought you said you weren't going to use the crossover when using DC.  If Tam Valley says you won't harm their juicer, one thing is for sure, the juicer won't be able to reverse polarity when DC is applied.  A juicer can reverse polarity for DCC because the DCC power signal is a form of AC.

Good luck!

Hi Vince,

 

Thanks for the tip. I bought a Klein 11061 wire stripper based on your recommendation. It works great on all wire sizes, solid and stranded. It removes the sheath from multi-strand cable without cutting or nicking the wire inside. I strip the middle of solid 12 and 14 gauge bus wires for soldering track leads. I'm throwing out my old Radio Shack stripper.

 

This tool is worth every penny.

Hi Greg:

 

 

The wire strip I use is Klein tools 11061 wire stripper.  I use it to strip solid and stranded wire.  It works great on my layout bus wires that are stranded #12 and #14 gauge wire.  I solder all my track drops to the bus wire.

The wire strip does a gread job of stripping the wire in the middle and at the ends.  Small wire gauge I have done are telephone wire and CAT 5e 24/4 which I use for wiring my Tortoise switch machines, signaling etc..  Wire stripper will remove the cover of the CAT 5e wire and expose the 4 pair of wires, which I then remove with the same wire stripper. I remove the individual wire cover, exposing the solid wire for inserting into the wire holes at the end of the tortoise switch machine for soldering,  The other ends go into euro wire terminals.  FYI, I am building a large layout, so I have a lot of wirestripping done and to do.

I appreciate seeing the email question, because it remind me to order two more of the wire spripper on Amazon for $19.97 each, plus taxes. Free shipping with Amazon prime.

It is worth trying.

I have a number of 'standard' wire strippers to do anything from 8 to 24 size.  However, they are for stripping the end of wires.  Are there wire strippers for taking out just  a section of the sheath so I can add feeders to a long power buss?  I have tried doing it with a pocket knife.  It works but is time consuming and it does scratch/nick the wire.

Re: Slip Rings for Turntables.

Hi Carl,

One could possibly make a slip ring out of a hair dryer or curling iron work.  The challenge is that the slip ring is likely molded into the housing and may be difficult to separate it.  It may also be a challenge to center it up on the turntable.  Since no two models are likely to be the same, it is hard to give advice on doing this.  Still, if you can get a hair dryer or curling iron for a few dollars, it is worth a try.

Thanks

Another source of slip rings may be your local hobby source. Look for
the slip rings used for things such as RC Tank Turrets.

Hello Allan:

Another source for a slip ring would be electric hair curling irons. I've played with these at Goodwill and thought they would work.

Re: DCC/DC and Dual Frof Juicer as Auto Reverser.

John Heaps
 

Hi Carl and Allan,

Thank you for your replies.

My plan was to wire it as in the diagram in Allan's website.

However I want to be able to run with either DCC or DC.
When running with DC the crossover will not be used, hence no reverse section.

If a reverser, such as a Tam Valley Dual Frog Juicer, has DC applied to it will it:
1. be damaged ?.
2. allow the DC to go through to the track, or do I have to isolate the Dual Frog Juicer ?

I will also need to use a DPDT switch to reverse the polarity of one of the tracks ( one of the black tracks on Allan's diagram) between the end loops when running under DC.
