Thanks for watching

I did add an elbow and extension to my drain when I was plumbing in the other compressor. They don't leave much room. I decided to put an electric auto drain on the extension, and vent it through the wall outside. Getting too old to be crawling around on my knees.

In reality they do regulate the pressure.... so it's not completely wrong.. but an actual pressure regulator works much differently and isn't a switcg

Nice catch. You are absolutely right. Didn't notice that when I was editing.

@@shadowpotatoe9482 sorry but you are wrong. A pressure switch is simply a switch to turn the motor on or off, no regulation of any type. That is why you add regulators to adjust pressure and volume. If you quite trying to justify someone's error you would not look as though you didn't know what you are talking about.

Thanks for the comment. I would love it if I could get 3 phase power to my house. Unfortunately its not available for me.

@@mdw66799 you could build a rotary phase converter and make a video of it 😉 eventually I will be doing it because 3 phase motors for me are dirt cheap, just need the time to do it.

@@TheWyleECoyote That's the truth. I acquired a 220v 3 phase lathe, and thought I would just replace the motor with a single phase motor until I priced one. Ended up putting a frequency drive on it instead for a fraction of the cost.

Portable bandsaws are awesome. I have been using them for the last 20 years working in a 1 million square foot facility. I don't have stock piles of metal in my home garage. The stand I made for my portable bandsaw is detachable and comes in handy for cutting small pieces accurately.

Yes it would have to be connected to the Pressure switch. You would need a check valve that has a unloader port and an air compressor pressure switch with an unloader. The way it works is when the pressure switch turns the compressor off when the tank is full, it activates the unloader on the pressure switch to bleed off the air in the line between the compressor and the tank.

​@mdw66799 OK. Thanks heaps for that info. I'll have a good look into that, then

I checked out your air compressor video. Is it possible that is some kind of check valve and unloader coming off of the cylinder head? You may not need to add an unloader. looks like a nice setup.

​@@mdw66799 Thanks. She's a beast. Lovely to use the belt drive compressors. No that brass bit on the exhaust side is just apart of its freezer days. I had a look at everything and from what I can see is it has the old pressure shut off switch for the freezer as well as there seems to be no allowance for a drain off pipe. I have now got a unloader valve coming and air compressor pressure controller coming. Lol so while I'm pulling things apart I'll give it all a clean up and paint

CFM is a pump thing not a tank thing. I have added compressors before when I had to run my plasma cutter at my in laws house,no 220 vac at the time.

You are correct, they are pressure switches.

I already had the one larger compressor. It was fairly new, and given to me by a a friend that was moving. Didn't want to spend money on a new compressor at the time. Saving up for a new lathe. I had the other compressor and motor sitting under my work bench with no tank. Thought it would make a fun video. I may go your route in the future if either of these two crap out on me. Thanks for the comment.

Thanks for the comment. Most of the noise is coming from the intake. A viewer suggested an intake muffler. I think I might try that.

@@mdw66799 I actually mounted my 60 gal. compressor on heavy duty castors. This way I can wheel it around if I need to move it. Two of the castors have locking wheels, and the rubber wheels reduce the vibration perfectly! :)

Not Really. I miss spoke in my video and called the pressure switch a regulator. A regulator lets you control your desired working pressure and a pressure switch controls which pressure the air compressor starts and stops. Same as a pressure switch on a well water pump.

The unloader bleeds off the residual air between compressor and the tank when the pressure switch reaches its shutoff pressure. This helps the check valve close which stops backflow of air from the tank going back to the compressor and makes it easier for the compressor to start on its next cycle. My thought was if the 2 compressors have different start and stop pressures the unloaders before the tee would prevent one compressor from working against the other at startup. If the unloader and check valve were after the tee when one compressor is running and the other is not, the air from the one compressor would be forcing air against the compressor that's not running and tank making it harder on the second compressor at startup. That was my thinking anyway. I hope that explained my logic for the unloaders and check valves before the tee.

@@mdw66799 it does. You could run both compressors off a single pressure switch. Probably require a contactor rated large enough for both motors. Very cool project. Look forward to the next.

In my case, one compressor is 220v and the other is 110v. I could wire them both to run the same voltage and use one pressure switch. Like you mentioned, that would be a big current draw at start up. I kind of like using just one unless I need the extra air. Thanks for the comments. Working on some more videos.

Good comment. I get carried away sometimes with my milling machine. A block of wood would have worked.

I built a Vapor Hone Cabinet and my Air compressor couldn't keep up. It ran constantly and at times I would have to wait for it to catch up. Now with two compressors I have no Problem. Could have bought a new compressor with more cfm, but I had this one handy and saved myself some money.

@@mdw66799 Thats pretty smart! I like the idea of one being quiet

That would have been the preferred solution for me too, if it wasn't for the fact that the Tank on my smaller compressor was rusted out and unsafe.

I have not increased my pressure and this is not the same as a 2 stage compressor. Both compressors run at the same time when they need to maintain the volume I need for the vapor hone cabinet. I am using Glass beads at not more then 50 psi. with a high CFM. The setup I have now works perfect. Also this was just a fun project that saved me from buying another compressor for the few times I will be using the vapor hone cabinet.

@@mdw66799 I've seen this attempt, and what happens is hotter air with more moisture and it's shortened the compressors lives, but it was well done, problem is when they are running at same back pressure will occur and over heat compressors

@@georgespangler1517 Except they have independent check valves so the compressors know no different. They operate independently of each other just share the tank

@@mrmotofyAh! Common sense has entered the chat! I have had three compressors running to a tank for increased CFM before. Same as what you said.

Need $$$$. This was free.

Thanks for the comment. I do prefer pipe wrenches when doing this kind of work, and did use them in the video where I could, but sometimes when working with small fittings and tight areas pipe wrenches may not be the best choice.

I've been a Pipefitter for almost 30 years. I have pipe wrenches in every size from 8"-48". I almost always use adjustable pliers on pipe/fittings smaller than 1". He did just fine...

The handles were tapered on all sides. I tried that first. That's why I milled them flat.

Awesome suggestion. Thanks

I couldn't afford one either. I converted a cheap harbor freight sand blast cabinet into the vapor hone cabinet. Watch my video kzfaq.info/get/bejne/eqmZm8Ka2bO5fnk.html
