My AC power panel

[Chuck Craven]

This is my AC power panel.
It is a basic 120V AC power distribution panel.
There is no in coming circuit breaker because it will mainly be used at home when not camping, for charging the battery and loading / unloading the tear.
Not shown is the interconnect power cable 20A ratted. Also their will be an adapter for 15 A / AC supply which has an 15A breaker built in to it. This is when camping at older campgrounds that have not updated their electrical service. I may make a 20 A pig tale with a 20 amp breaker if I find I have to. But that will be done only after the tear is built and if I start camping at state/fed campgrounds that have not been upgraded to the new electrical standard.

Like the idea of having receptical tester on board and lit as indicator that proper shore power is getting to panel...

Very nice. Did you make or purchase your panel? Danny

The panel is .90 “ aluminum, clear anodized. I did the holes and engraved the panel on a CNC milling machine. The panel was made from some scrap found in the scrap bin.
I have another piece the same size for the DC power panel, which is being worked on now.
All the parts for the panel are from the ACE hardware store exc. the 20A. inlet plug and the two fuse holders.

Nice job Chuck

SWEEEET! Real nice job.

Chuck,

Have you considered making and selling those things?? Especially one for the 12V side.

Chuck,

Yes!
I think I will be retiring next year! Lets see I have taught my job to the Mexicans, Chinese and now to the Indians. I think sooner or later they will find some one to do my job. If they would have video taped the first time, they could have gotten rid of me long ago. Shush, Shush don’t tell any one!

My homemade CNC mill is a little shaky right now. I just built a new motor drive board that will handle the current of the motors. Also rebuilt the motor driver power supply so it can handle the current. So all that is left to do is install the drive board and rework the Z-axis just because I don’t like the whey it is right now. I have been thinking of a hobby biasness to help me keep busy once retired.

Like to divulge a little more info on this homemade CNC mill? That's something I'd like to hear about.

It is a flat bed beam mill.
The table is ¾” by 21” by 35” aluminum plat. The X-axis has double wide linier bearings on 1” ground hard steel rods. The Y-Axis is 1” rods also but I am using 4” oillite bearing stock. The Z-axis is made out of Delran use a dove tale bit in a router to make the ways. It worked OK when I was using a Dermal motor tool for the power head. The Dermal did not have enough horsepower to do what I wanted. So now I am using a Roto-Zip for the power head. The Z-axis is to light to handle the bigger motor so I am rebuilding it.
I am using stainless steal all threaded rod for the drive line with 200 in oz stepper motors for all thee axis. Designed my own anti-backlash nuts.
I just put together the Hobby CNC control board but have to install it on the mill. A couple of weeks ago I got my 48V 10-amp power supply running. My old controller board is home made, was designed for 120 in oz motors and can’t quite handle the higher current of the new 200 in oz stepper motors.
I use three different software packages first is a drawing package that saves the layout in HPGL file format. Then I use a freeware package for editing the HPGL file.
Third is a freeware HPGL to step and direction driver, which I rewrote for my driver board. Now days there are some nice low cost CAD/CAM software programs that can do the same job. Once my mill is running the way I want it. I will bye a program to replace the make do software I now use.

Nice panel! I realy like the design. Can't wait to see the 12 volt panel. Also how about some pics of your home brew CNC machine?

I'll second that, I'd like to see it too!

Well I tried to take some pictures of my mill awhile back but all I got was bright reflection. Aluminum does not take good flash pictures!+ The mill right now is in the darkest corner of my basement. The DC panel is progressing along, by next weekend it should be ready for the mill. Right after that the Z-axis gets pulled apart and rebuilt. Once that is done I will try to take some pictures and post it.

Use bright light to light it up and turn the flash off on the camera. We want to see it!
