Two Channel Extension Cords

Here's a great idea from someone who shall remain nameless.

DISCLAIMER
I have built and used these for many years. Do this at your own risk. These cords share a common neutral wire and the total current draw for both channels must be less than what you would normally have on a regular extension cord. A 14 gauge extension cord can usually handle a 12 amps up to 100' long. So if you were to make a two channel cord, each channel should have less than 6 amps load.
I am not an electrcian or a lawyer to do all this at you own risk.

I have cut an elongated hole which will be the bottom of the holder. This slot will allow the XLR plugs and power cord to hang out. Notice the splines around the inside of the lip of the flower pot. These line up with the holes around the bottom in two places but they do help you align your cut hole. The elongated hole is 2-1/8" from the bottom, 2-1/2" wide and 1-3/8" high. I cut it with a small carton cutter but a #11 Exacto blade would work too. I also drilled two holes in the sides.

 

In this shot you can see the side holes. These were drilled at where the side of the pot begins to taper. You can see the line around the inside circumference. These holes were drilled where there were splines along the lip as above. I did this as they were 180 degrees apart. I then hot glued nylon washers on the inside. This reinforces the holes and helps space the fixture in the center of the pot. I also used hot glue to reinforce the oblong hole and prevent it from cracking. I have a two temperature hot glue gun and "Hot" setting just about melts the pot but that way the glue is bonded to the pot. I did a test piece and the hot glue really strengthened the plastic.

Here is the Chauvet 200B DMX color wash fixture. I pre-installed two 12" XLR cables (eBay) so I wouldn't need to try and connect them once the pot is installed. I also pre-programmed the DMX address as I won't have access to the DIP switched once the pot is installed. It's also a good idea to test the fixture before you encase it ;-)
I also taped the plastic washers to the fixture. These washers came with the fixture.

This was a test fit to be sure the cords fit and the holes line up. With the two washers on the inside of each side of the fixture, the flower pot remained fairly round.

This is the fixture (tested) installed in the flower pot. I also added two rubber washers on each side of the yoke. This will help seal the holes and keep the yoke from moving once the wing nuts are tightened. I also used a little hot glue along the lip of the flower pot to keep the fixture from rotating. Once I silicon the cover on I don't want the fixture pivoting and possibly popping the cover off.

This is the 6" pot bottom that gets siliconed to the bottom. 8" pot and 6" bottom tray. This way the bottom tray fits right on the end.

This is a completed fixture in the flower pot. I used plastic diffuser lens (2' X 4' from Lowes)and cut them in circles. A band saw or roto zip works best. There is also a small flower pot bottom pan (also plastic) hot glued to the back (bottom) to cover the flower pot holes.

Once I build the stands to hold these I will add pics.
