Doing nice work is a lot of work.

Make a plan and stick to it. Makes the fabrication much more enjoyable.

Field-expedient Tabletop Sander

The bulk of the load is carried by T-nuts.

I made this little platform so I could get holes perpendicular to the work without having to jump through hoops. (Crappy Harbor Freight vise...)

Handle became a prototype because bad contour and bad design.

New Profile

T-nuts at the top and 1/4 x 2-1/2 Spax at the bottom. You have to install the caddy onto the battery.

Spray paint worked very well for the trim. I used satin finish paint, then a water-based urethane over top.

Ready for prime time!

Feet for a finishing touch and to keep the wood off the ground in case of water.

VOILA!

I give myself an ‘ A’ for this one. My wife said it looks like it belongs on a Chris-Craft.

That came out absolutely beautifully! Very skilfully done.

Using it as a homemade booster box, portable power source for RC recharges, or?

Looks nice. Are you going to attach the inverter permanently?

CPAP machine whilst camping, primarily.

And thanks for the compliment!

Thanks and probably not. At least not until I’ve established how I want to use it all. There’s also a solar panel and a charge controller, which I’m not going to use on this outing.

Though I’ll take it camping, the primary purpose is provident living so I can use my CPAP at night in the event of catastrophe. #puertorico

Have tested it out for that yet? I have a C-pap, and have been considering pulling the trigger on a generator. That will cost me hundreds though. If this works, I’ll do this.

Little box with 12 screws and entirely made of scraps. Two days.

Works great . The DC adapter for my CPAP is rated 12VDC/5A. So 60 watts. I plugged in that little 300W inverter and ran the CPAP. I used my ammeter and measured 0.47A at 120VAC, or about 60 watts.

My battery is rated, I believe, at 85 AH. My CPAP, running for 8 hours, would consume 40 AH. The Internet says you don’t want to deplete your deep cycle batteries beyond 50%. So it’s perfect.

I also have a solar panel that’s rated at about 5A, 12VDC, and a charge controller. So I can run the CPAP at night and recharge via solar during the day. I haven’t tried the solar piece yet. I bought the entire setup from a guy who took it to Burning Man.

So, Mr. Shop Teacher, can I get an A for my fabricating? I am especially pleased with the trim. I used satin finish spray paint, then covered it all with water-based semi-gloss Zar.

Oh yeah, you definitely get an A :)

I’ll have to see how much juice mine draws. I looked up what the manufacturer says it draws, and I thought it was something like 180 watts, but I should measure the actual power consumption.

Look at the small print on the DC power supply for the CPAP . I’d be surprised if it was much more than mine.

Mine doesn't have a DC power supply.
