Now you've got me wondering what a 212CI-powered air compressor would sound like. In the world of so-called modern tools struggling to go ever more quiet, a fat, choppy V-twin compressor would be amazing! I'd have to find reasons to run it as often as possible. 😁

Appreciate the tips and tricks that's a nice set up u got there keep it coming motivation watching an learning 👀🍿💪

[@ltprecision888]

Thanks for taking time to put all of this together. You should use some of those awesome skills to build a work bench.

One of the things that has vanished from the country is DIY ingenuity. All the old farmers and ranchers were always making their own inventions from scratch for the various situations that arose. So many things are able to be purchased pre manufactured in our day that this is completely lost! It was fun to see you throw all that together. From a truck driving perspective, id like to see you rig up and UNBELIEVABLE strobe light show/set up for roadside work. Im talking massive show of force, shock and awe type lights! Drivers are getting scarier each week out here on the road. All the extra stuff you can come up with to Catch their attention will help keep you safe while busting beads along that crazy I-15 corridor.

[@kmac9759]

And its so much cheaper to do it yourself. My hope and plan is not to do roadside repairs. Im looking more toward cars and pick ups. The heavy duty tires I want to do is night and weekend work for someone replacing a set of worn out tires. Ill go out to where they park the truck instead of them having to have the driver sit at a tire shop and down the truck for half a day.

[@realwildwildwest]

@@kmac9759 I like that plan much better than roadside ! You’ll find a great niche there doing tires in their yards. Way to get after it 👌🏼

[@kmac9759]

Yeah, I’ve done the road side work. No thanks. With that being said. If your in the Utah I-15 area and have tire troubles, give Utah Mobile Tire a call. Should be up and running soon.

found your channel through your truck box drawer build. i came to your page, and your home page says "This channel doesn't have any content" its not until i click the videos tab that i see your videos. i almost clicked away thinking it was a dead channel. might want to make your home page, unless it is intentional. Cheers!

[@craigmonteforte1478]

nice Fabrication ! in my large Woodworking Shop we started using a lot of Clear reinforced Air hoses for short runs grant you it was all indoors and out of Ultra violetRays we used those quick Hose Clamps that got Crimped on with their tool designed for just that i was with the Compant for 35 years and we never had any failures of those simple small runs it was Simple Easy Peasy way to connect fittings and even a few small tools here and there to our Hard lined system honestly we grew so confident in them that we have plumbed some semi permanent machinery utilizing those same systems I mention that not to be a Know it All but to offer a possible Solution that may be faster than waiting for a CustomBraidedLine as you stated you were getting for the new Compressor set up and a business start Up business venture

[@AdrianRodriguez-xi7ex]

Great video!! That was neat to watch. Also neat to see those tanks you got tucked under there. 🤩😂👍

[@harveyottotech]

Very cool! I hope you have a video about your truck compressor setup.

[@peanutsmith1462]

Man what great idea

[@rogertaylor8615]

Cool that working good

[@jjsteen99]

Sick work. Castair can set you up with this setup or parts whatever you need call Clint

[@MichaelJeffers75]

I built a similar arrangement for my house electric compressor (5 HP) with a motor and pump on a big piece of C channel and had a hell of a time rigging a tensioner and alignment mechanism. Did your build have the same experience? I had to put opposing draw bolts on the motor to pull the motor to tension the belt, and the other side pull the motor back towards the pump to counter the torsion and align the pulley.

[@nasa1man]

I have a question I have a GX 200 Honda Thanking putting that engine to work on this kind of project I have a question what What size air hose did you use connected to the unloader valve

[@franks551]

What sizes did you use for the fitting from the compressor to the tank

[@sinistan1002]

i was going to do something like this last year for blowing out sprinkler lines I didn't really need a bladder tank for that purpose just so much pressure and a lot of cfm behind it

[@axisvaporhoningindustries4312]

Going to put one together with a 20 Hp eaton compressor and 22 Hp Predator engine. Good for 62 cfm at 100 psi.

[@joseHernandez-uu2cx]

Can you just weld a square 30 gallon tank and put on top of your exhaust?

[@antoniozepeda252]

Nice work, i am about to build mine this weekend exact same setup, i just have one question, With the 3.5 pulley, what size is the belt?

[@kmac9759]

I dont remember. I got it put all together and measured it. But that was a plate I had in my garage, so it had to put the pump and engine fairly close together.

[@TheVinnivee]

Could you tell where to get the unloader valve?

[@QPkam]

What kind of on board compressor are you running on your truck?

[@vim_usr2753]

Do you think a sled made out of 2x4s and 1/2 plywood would work? Just trying to think of some other possible options since I don't have a press break, plasma cutter, or welder.

[@kmac9759]

No, it shakes quite a bit and I think it would just tear it apart.

[@vim_usr2753]

@@kmac9759 Gotcha.

[@02lb72500HD]

Im in the process of building one of these myself. Only thing im gonna change is gonna run a clutched pulley on the engine that way im not always spinning the compressor. And on the throttle side you might look into an air actuated throttle.

[@kmac9759]

It has an air throttle. I didnt have the parts to connect the throttle cable to the engine. Ive got it all hooked up now so it idles when it cuts out. Its been great. I have an 80 gallon tank in a trailer, its a little slow to keep up with my 1 inch tire gun but other than that its great.

[@StephenBrewer89]

@@kmac9759 would a smaller driven pulley help with your recovery speed? I would imagine more compressor RPM means more cfm?

[@kmac9759]

A larger pulley on the engine would help, but the pump is already at its max rpm. Ive got a different pump in my garage that I’m going to build another one with that is way bigger than this pump.

[@StephenBrewer89]

@@kmac9759 ah that makes sense. 👍🏻

[@vim_usr2753]

@@kmac9759 Any chance we could get a small update video on the compressor setup? Curious how you got the throttle setup properly. Wouldn't mind seeing the 80 gallon tank/trailer setup as well. Great vids!

[@fitch8363]

Neat system. How do you drain the tanks on the truck?

[@kmac9759]

The tank was in the trailer. Had a valve in the bottom.

[@cndnknight]

I am currently trying to figure out if I should but a whole compressor or build one. My largest determining factor is choosing a compressor pump to match the motor. Do you have guides or tips for this?

[@MichaelJeffers75]

If you're mechanically inclined, definitely build one! Eaton has great American made cheap pumps that can be paired with any motor, and any pump can be driven by electric motor or gas engine just the same. I bought a large shop compressor from Marketplace for dirt cheap and had to redo the mounts on a different piece of C channel, and add a new elec motor, so essentially I built a new unit, and the process isn't that complicated. Only tricky part is working out the tension/alignment problem, but adding opposing draw bolts to each set of the motor mount bolts solves that. I have some video of my build on my channel, though it's not formatted to gain a following on KZbin, just a guy showing my stuff.

[@sinistan1002]

depend on use case i was going to build one last year for blowing sprinkler lines out primarily i.e. short run not painting / sanding for that you don't even need a tank just a powerful enough pump + engine. big tanks by themselves seem to cost nearly as much as a whole complete new compressor but for some reason the pumps + engine alone is far cheaper, probably cheaper to do that and get a smaller bladder tank as long as the cfm is high enough it can probably even be a 10-20 gallon tank

[@BogeyProductions]

Would it consistently give out air? Also would it get very hot after a while running?

[@kmac9759]

Its pretty reliable. The pump is a little small and I have to wait when I run my 1 inch impact. But it does pretty good for what it is.

[@AC-er2kq]

Parts list ???

They just push the throttle back to idle when the unloader charges

[@michaeldaye7889]

What size air tank and do you run a 1” impact?

[@kmac9759]

This compressor was put with an 80 gallon tank. Its a little slow for a 1 inch gun, at least for the professional aspect. But for here and there use it is fine for the 1 inch gun.

[@tuckerc3802]

That engine and pump can fill a 60-gallon tank can you please try painting with it or sandblasting so we can all know if it'll handle it because with a two-stage pump that should be more than you need with any tank size you should keep up with sandblasting & painting I just don't want to waste the money and be bummed so please do some testing

[@nickwhite6717]

2 stage of same volume primaries pushes less cfm than single stage

[@killnconquer2645]

What about adding a generator to it to power electrical tools

[@kmac9759]

I am sure it could be done, but it’s beyond my electrical knowledge
