Conductive traces (was: Re: [HOn3] MDC Moose Jaws Loco)

Bill Lugg
 

Not directly applicable to the Moose Jaws topic, but possibly useful in general, here are a couple of links to materials that I've seen written about in the MR press recently:

https://www.amazon.com/CircuitWriter-Conductive-Ink-silver-based-4g/dp/B00B88B9KI/ref=sr_1_7?dchild=1&keywords=conductive+ink+pen&qid=1604849521&sr=8-7

This one was in an article in MRH I believe and was used to conduct power to lights in the shell of a diesel.  Unfortunately I don't remember how the wires were bonded to the trace now.

https://www.amazon.com/Zehhe-Copper-Foil-Double-Sided-Conductive/dp/B01MR5DSCM/ref=pd_bxgy_img_2/144-3426246-5575703?_encoding=UTF8&pd_rd_i=B01MR5DSCM&pd_rd_r=950798c1-d0db-4281-9bbb-d0a7a72f876d&pd_rd_w=LVqoV&pd_rd_wg=1ezQC&pf_rd_p=ce6c479b-ef53-49a6-845b-bbbf35c28dd3&pf_rd_r=3Y1XG0XNY30SRYGZFJPX&psc=1&refRID=3Y1XG0XNY30SRYGZFJPX

Here's the copper foil tape I think Dave is talking about below, 21.8 yards of the 1/4" wide material seems like it would last a long time for an HO model builder and the price seems pretty reasonable. I'm not sure it would solve Kevin's issue though.

Not sure of availability in Europe but here in the U.S. Amazon has
it.  I bought a four roll pack (life time supply) for $12.  Search
"copper foil tape".

I used mine for a electric distribution bus inside my East Broad
Top roundhouse.

Never thought of it for on an engine or rolling stock. Thanks Mark!

Couldn't you pick up off the insulated side of the drivers with some 
carefully placed wipers?
Just a thought...
Bill Lugg

actually, that was my first plan for picking up current. i may still yet do that, depends on how well things work.
thanks for the input.

Re: HOn3 standards gauge

Bruce
 

I model the East Broad Top.  They mounted standard gauge cars on narrow gauge trucks and ran them across much of the railroad.  I use a NMRA HO gauge to ensure clearances on my layout.


Re: HOn3 standards gauge

Mark Kasprowicz
 
Edited

Perhaps the NMRA is going to correct the HOn3 gauge. The overall clearance on the metal version does not allow for the largest HOn3 locomotives such as D&RGW K37's which were coverted from standard gauge locos. It was fine for Baldwin C-class, but too small for some of the K's (not sure exactly where the dividing line is). I was told to use standard HO clearances for this dimension.
That said the metal version still available from the NMRA

I just looked, and on Ebay UK it's here.

It is available in the US but I only found it in rolls large enough to last many lifetimes costing $$$$$'s.

The other option is to just make a new cover plate from PC board material.  Add phosphor-bronze wipers, and wire it up.  See attache'd pict.

Re: MDC Moose Jaws Loco

Mark Kasprowicz
 

It's fairly standard to glue a narrow piece of PCB board on the insulated side of a loco and solder phosphor bronze wire onto it as wipers.
Using a trailing truck even a four wheel one gives just two wheel pickup on a narrow wheelbase - that's going to result in the supply having continuity issues, especially on turnouts.
There is an alternative to PCB ties and that is copper coated Kapton sheet. It's not easy to find (I got mine from the Czech Republic!) but its much tinner than ties, can mould to a shape and can be cut with scissors or a craft knife. The only thing to watch out for it making sure that the edges are insulated from the frame and I do that by letting the epoxy flow out from the sides slightly and check for insulation with a multimeter before the glue sets.

Re: MDC Moose Jaws Loco

Mike Conder
 

Yes, that works and is better than relying on tender or pilot trucks.  

IIRC best way was something about epoxying a PC tie to the gear cover plate, with phosphor bronze wire solder to it so it can rub on the back tread of the insulated driver.  May be thinking of another loco though ... been a while since I looked into it.

Hello All.

caught a break today, actually had some time to tinker at the train bench:

made a little progress even.

one thing (trailing truck)  is now decided. it will be a ?-8-4t.

as this is a saddle tanker, i will have to pick up one leg of current from somewhere, so, it will have to come from the trailing truck, and possibly the lead truck.
the drivers will supply the other leg.

thanks.

Have you read the correspondence from the organization regarding rolling out a new store? I just went to the site and found On3, Sn3, HOn3 and standard gauges. It’s there guys. Are you logged in as members?

Eric,

    Is your question related to the fact the NMRA has just released plastic clearance gauges for most of the various scales and gauges, including ones for On3 and On30, but nothing for HOn3, which I believe is a larger market that the other two combined?  This would not be the first time the NMRA has done some pretty squirelly (sp?) things.

as this is a saddle tanker, i will have to pick up one leg of current from somewhere, so, it will have to come from the trailing truck, and possibly the lead truck.

Re: HOn3 standards gauge

It might just that they are currently out of stock and therefore not showing on the website. Let’s not “throw the baby out with the bath water“ as the old saying goes. 

The NMRA does many things that are beneficial to all scales.
