You can make up paper labels on the computer, and use clear heat shrink over them.

Cheap, simple, easy, and look good.

Yea, that's exactly how I did mine and they're OK but...Scott's are the same as Stein uses on their harnesses and they look great and are easier to read.

If I do it again I'd beg Stein to print a bunch for me. If that didn't work I would remind him that I aint broke yet! That would drive him nuts.

Default Dymo RhinoPro 5000

A year ago I bought a Dymo 5000. Very impressive for it's features, and it's available at this link for $87.

http://www.labelcity.com/eonline/itemdesc.asp?ic=15517

It's not very intuitive to use, but I made a couple of cheat sheets so even when I don't use it for a while I can get things done without having to figure it all out again.

The tape for shrink lables is expensive. The 1/4" size is $30 for 5' of label. The 1/2" is too big for most wires in an RV but fits over tab and ring connectors. The 1/4" is fine for our wires but doesn't fit over tab and ring connectors. The end result is unless you have wire without a connector on it you will have a hard time retrofitting these shrink labels.

There is also a heavy duty Nylon tape (not shrink-tube) which costs about $20 for 11'. Despite what the website says, it does not seem to stick really well, even on clean wires under the panel. I think the problem is the label is just a little too stiff to roll over the small wires in our planes.

On the plus side - the black on yellow is very visible and looks sharp but I'm not sure it's worth the price. I think knowing what I do now I would get some yellow paper and print a bunch of labels on the computer and laser printer, then use clear shrink wrap to attach the label to wires.

Default Left Side Firewall Ground Block

I'm bumping this thread as I'm looking for a single, good location for the forest-of-tabs ground blocks, brass bolt, and engine-side firewall ground location and also for the engine monitoring wiring to feed through (for my Dynon SV-EMS-220).

Since most of my RV-8A's firewall aft-faces the forward baggage compartment or the rudder pedal area, I've decided my only option is on the lower left side of the firewall. That area is pretty busy with the fuel pump, heater valve, and aft battery cable and looks like it'll get even busier later with control cables and who-knows-what on the engine side.

Can anyone post a picture of their setup showing both sides of the firewall so I can de-conflict future problems? I like the look of Scott Chastain's photo in posting #3 except I want to utilize the lower left side. And I'd like to see if there will be any obstacles on the engine-side later.

Thanks,
Joe

Default Grounding block

I have decided that I am going to fabricate a false floor in the bottom of the baggage compartment on the right side of the aircraft. My plan is to seat the false floor on the forward longeron and install a angle with matching slope on the inside wall of the baggage compartment. This will allow the forest of tabs to be mounted low on the firewall but take up a minimum of space in the compartment. The false floor will be removable and leave about 3 to 4 inches of space under it for the ground wires...any comments on this plan?

Luke - That looks like a good place for it. It keeps the baggage well open and usable and it is not in the area where there are fuel lines. Four questions:

1) It is hard to see from the picture but it looks like there is a bolt that goes through the firewall to the engine side. Does the engine ground connect to that same bolt?

2) Do you have a firewall mounted battery or an aft battery?

3) Are you running a fat ground wire from the terminal block in the pictures to the battery?

4) Is there any possibility of contact with the rudder pedal? I would not want the rudder pedal to damage the ground wires going to the block.

I've a firewall monted battery (Odissey PC680), the bolt shares ground battery cable, gnd engine case and the ground tab.

4) Is there any possibility of contact with the rudder pedal? I would not want the rudder pedal to damage the ground wires going to the block.

NO, there are not possibility of any contact !

Default Another option

Sometimes I sacrifice function for the sake of organization. I isolated the mounting of a B&C block. Behind panel where it is needed. Preserving the baggage area for something important like a smoke oil tank....

Running #6 out to firewall mounted battery and airframe ground. I don't have a real grasp on the ground loop phenomenon but will only ground one end of wire shields.
