How to build an air compressor, DIY air compressor, part 1

I'm building a twin cylinder air compressor using a 60 gallon air tank, and a 2 HP motor. The pump is capable of delivering air at 11.2 cfm @ 90 psi, and should easily reach 120 psi.

You know you're getting old when you see a big ol' slab of metal plate like that and remember how affordable it was not long ago.

Tip : lay a small piece of dowel or round stock in the grooves of both pullys when eyeballing pully alignment. Makes it much easier to get the alignment straight. Nice compressor

Nice tip!

Next time fill the copper pipe tightly with sand (Play sand $3 a bag at Lowes).Duct tape the ends and you can easily bend it without fear of kinks.

Hey! Good Idea.. Thanks for watching.

As soon as I saw your first compressor video and you mentioned you were making your own table saw, I knew we were kindred spirits lol got a new subscriber for that one 👍🏼

[@DurangoExpressTrucks]

A trick for bending the copper lines without putting a bunch of dents and kinks in it is to roll the copper tube out in a straight line, cap off one end with tape, fill the copper tube with water, all the way to the top and put it in your freezer. Let the water freeze. Now you can bend the copper pipe into the correct shape and tight turns without kinking it flat.

Nice I never knew that

Can you use AN fittings for the copper sections?

[@dowboykfx470]

Is building a air compressor more bang for your buck versus buying one?

[@WayneEarls]

Probably not, unless you get most of the things free like I did. I bought the pump and gauges, but I got everything else including the motor free. Thanks for watching

How you figured the distance between both pulley

[@kariymchristopher6986]

What is the thickness of the base plate you used

[@luiemeza455]

I plan to rebuild I 1974 compressor air lines. Where can I buy those same copper lines and fittings. Should it be rated for certain pressure. Great video by the way

[@WayneEarls]

+luis meza Thanks for watching! Around where I live you can get copper at about any home improvement store or hardware store.

[@kelvingreen532]

@@WayneEarls what are the fitting sizes for both pump lines ?

[@BillyDocWalker]

It a good that God takes care o fools and edicts

[@jasonputtock4428]

would be nice if you linked your twwin cylnder item.

[@WayneEarls]

Good idea. I'll see if I can find it again. I plan on making new videos. Please sub. Thanks for watching!

Why are you putting the pressure switch in the crankcase vent ? On most air compressors the vent for the crankcase is behind the big pulley at the top .

[@WayneEarls]

On all the compressors I looked at that's where it hooks. The crankcase has to release any pressure it has when it shuts off, so that it will start back up without a load on it. It releases the pressure via the unloader valve in the pressure switch. The switch has the 1/4 compression fitting built in for it. It's what makes the pssssshhh sound after it shuts off.. I've only seen this small tube on the larger industrial compressors. I'v not seen this setup on small compressors.

[@MrHowieZ1973]

+Wayne Earls I am pretty sure if you run that tube to that vent you will blow out the seals on the block . I could be wrong but I think you need a T up close to the large head with a small fitting for that release . I dont know it all . Just dont want you to ruin your new head . I am not sure how the unloader valve should be hooked up but I am thinking it should come out of one of the heads not the crankcase . Good luck :)

[@WayneEarls]

+Harvey Zearing I will check into it more. Like I said in the video, we are figuring this out together. lol

Worst pipework I have ever seen!
