I still have not pulled the trigger on this. Got the money sitting in PayPal but haven't made up my mind. Running the electric is kind of the stall right now though.

If you find a Worthington or old Eaton for cheap snatch it up. Can still get parts for both even after all these years.

I bought a dinky hose on a whim from the local welding store, it's a 'Flexeel' hose, so far I LIKE it! We'll see how durability is, but it's so small OD I can leave it in the utility room coiled up so it'll probably last a good many years as little as I use it.
Isn't Craigs List where you pay to have a serial killer kill you?

Most low end air dryers aren't worth the money spent as they still allow moist air to enter the system. Basically good preventative maintenance is the cheapest and easiest way to manage the moisture.....drain the tank on a consistent basis. All in all, one can spend $500 and have a really good compressor that needs to be managed a bit.....or you can spend $5000 and have a great system that will take care of itself......I personally opt for the $500 and manage it myself!!
At 500.00 It's almost disposable anyway. hahaha

I open carry a .45 on my hip, maybe it's what deters the psycho's lol

I finally rigged the starter on mine today, took a few pics... this is what you need, only maybe in a vert tank.

Dad painted cars for 30 years without any air cleaning system, but you have to be pretty careful, even then it doesn't take much to start getting defects. Saw contamination pin-holes all too often. The new system my brother put in the shop a few years back is amazing! But it's way overkill for a hobbyist.

Check it out, 1974 Worthington 2-stage. $300.00 plus $150.00 for the 5hp 1-phase electric motor. There are deals out there if you're patient.

In the second pic, if you look at the plumbing from air filter to the left cylinder a line runs to the right cylinder, then to the tank. That's a 2-stage (good) If both cylinders pulled from the air filter (inlet) and fed the tank, it would be a single stage. Single stage is fine, you just don't get the super high pressures that allow you to run cfm consuming tools all day long without pressure drops. 140 psi in a 80 gallon tank is a LOT of air!

I added a 3rd pic showing the difference between a 50' rubber 3/8 id conventional hose and the 25' Flexeel hose. The rubber hose weighs 10 pounds or so, the flexeel don't even weigh a pound. If this holds up well I'm going to get a larger id Flexeel in 50' for sure!

230v but I left the motor starter on, use it as an on/off switch.

I gotta just get off my ass and run some romex. But my outside box does not have any extra slots. Not sure how to handle that. I thought it did but it does not.

I have a separate service just for the shed it's in. If the city allows you to do your own electrical work it wouldn't be too expensive, but it would still be beneficial if you know an electrician that can keep you to code.

I was really fortunate that the shed is right at the service drop, so wire runs were minimal.

I might try my small compressor, it's a 115v, on my pickup lug nuts later just to see what happens. If I do I'll let you know how it did.

I just realized I may be recommending an elephant gun to someone that just wants to shoot rabbits and the occasional coyote

Ya but I don't want anything to be left of the Rabbit or Coyote. haha

My garage is at the furthest point away from my electric box. I installed a brand new box and seperated the meter after Katrina pulled the whole power mast off of the house. Never got it inspected and got lucky that it was still declared emergency so they did not look for my certificate of inspection. I can run one seperate after the fact without detection no problem but I'd have to get a different face inside or put a seperate panel inside as well. Might just run the wire and put a box in the garage.

Going back to the problem that started it all.....
I did a quick test with a ~300 lb ft torque wrench on my portable compressor set at 90 psi, it removed a lug nut pretty easy.

I had a small air leak at the wrench just because I was too lazy to grab a wrench and tighten the fitting, but it still kicked on pretty often just messing around. I actually got the small one for inflating tires and running nail guns which it does just fine. I was curious if it would spin a torque wrench, even though I don't think it spun it at 100% of it's spec it was still enough to loosen that lug nut.

Is that similar to your portable? Or do you have another type?

Right now I have a 3 gallon pancake compressor with a short line to a 10 gallon overflow tank. Plenty of air but the CFM sucks.

In other words, when they advertise a 2hp 110v electric motor they're WAY overrating the hp, 2hp 110v would need close to 30 amps to run.

If there are any electricians, please correct me if I'm off

{edit} they're probably also overrating their pumps cfm and volume, be aware.
2 hp at 120Volts(110 really doesn't exist anymore, unless you have voltage drop) but off the top of my head?? 1 HP =746 watts @120 volts= 6.2 amps x2=12.4 amps@ 80% of 15 amps(12) your ok with a 15 amp breaker

110, 115, 120, can't they all just get along?

Thanks for the input
