Hey all,

Ive started the planning process for starting my new layout. Ill have questions throughout, so I was thinking I would ask them on this thread as they will pop up from time to time.

First, does anyone have any problems operating Double Stack Intermodal equipment on/thru this bridge? I am particularly concerned about the 2 7/8" clearance of the bridge itself. http://www.walthers.com/exec/productinfo/933-3012

Second, an electrical question. I am planning on using 14 guage solid wire as my track bus. How do you guys splice into it? Strip the insolation and solder feeders onto it? If so, how the heck do you do that without almost accidentally cutting the wire itself? Do you guys used stranded wire for your track bus? If so, it seems hard to find a 14-16 awg in that.

Third, do any of you use Suitcase connectors? I think their made by 3M. Does anyone know where you can buy these in bulk?

Thanks,

Brad
 
The bridge might not work with double stacks, you may have to modify it. Easy to do.

I just measured my clearance on my double stacks and they are 2 7/8".

I have a short Atlas bridge that had clearance issues, and I had to modify the top supports.
 


Harbor Freight Tools has those suitcase connectors at a good price...if you have that store in your area.
 
Cool, I love that store and I have one about 3 miles from my house. Is that the way to best connect to solid awd wire?
 
It seems to be the most wisely used method of attaching feeder wires to your bus wire.
 
Anybody use Tortoise Switch Machines with Peco Code 83 Insulfrog turnouts? Any quirks about them?

Thanks
 
Posi-Tap connectors are used by some. They are more expensive than suitcase connectors but have some advantages.


You can create a bare spot for soldering to an insulated wire with an Ideal Stripmaster tool.

This is what I used to open up the insulation so I could solder to my bus wires.

Suitcase connectors are definitely the easiest way to go these days. However, be aware that they come in a couple of different wire application sizes, so be sure to match the choice of connector with the sizes of wire you are using on the layout.

I use these a lot:

I keep a lot of those in stock and use them on remote start installs and other audio/security related installs. Blue would be best for 14-16 ga.
 


I also heard you can adjust the spring's tension and just leave it in by adjusting it with a small screwdriver.

You must be talking about the older versions. The new Peco code 83 insulfrogs have a tiny spring in between the ties.

No way to "adjust", either it's in or out. Once you pop them out, they are a nightmare to get back in. Ask me how I know this. :eek:
 
Any advantage of one over the other? Voltage/current drop? It seems cost is about a wash between the suitcase connectors and the stripping tool.

I used splice connectors without soldering on my current layout with no issues but would like to go the bus wire/drop feeder route due to the new layout's planned size.
 
I have a lot of left over connectors I would be willing to sell if you are interested. I can check what I paid and what they are rated if you are interested. Let me know and we can go from there. I ended up getting more then I ever would need.

Dave,

Id be interested. It might be late winter/early spring before im ready to move on it though. Also are they the 3m 905s? i need something thatll take 14-22 gauge wire.

thanks,

brad
 
I will check to see the gauge but I do recall them being something like 14-22. I had them for the same reason you did so can't be much different. I do think they are 3M but not sure since they were purchased from a modeler on-line and not store. I'll check and get back to you.

Im planning on using Tortoise switch machines and using DPDT toggles to contol them. Anyone know of a good source for those? I know Miniatronics makes them as well as Radio Shack. Anyone have a good source and at a good price? I think ill need about 6 to 8.

Thanks
