    Sprayvana... or how to drop too much money on finishing.

    Okay, so I admit it, I was trying to make the old Central Pneumatic 2HP 8 gallon compressor do duty driving a spray gun. Hey the specs on the spray gun were fairly low, But having to stop so often to let the compressor catch up was getting old, FAST... I mean it worked, more or less. But progress was painfully slow. So even with the upgrades I made just a few days ago on the little compressor, I did what I should have done in the first place, and got a bigger compressor...

    The work needs to happen now, and now I don't have 220V, at least not yet. So I was looking for the best 110V compressor I could find, and as I had mentioned it before, I had it narrowed down to 4 compressors, a Craftsman Horizontal 25 gallon, a Husky Vertical 30 gallon, an Ingersoll Rand horizontal 30 gallon, and a Central Pnuematic vertical 29 gallon.

    After reading the reviews, I quickly wrote off the Craftsman as too unreliable, and after reading the price tag, I wrote off the Ingersoll Rand as out of my price point by a factor of 2. I really wanted to stay under $600.00 for everything... That left the Husky, and the Central Pneumatic...

    The reviews for the CP were actually quite a bit more favorable as Husky seems to have shipped a few that pick up a rod knock during break it (NOT a good thing), but Home Depot did offer the extended warranty. They were both close enough in price, the CP for $349.00 + tax and extended warranty, the Husky for $429.00 + tax and extended warranty (anything that expensive gets the extended warranty. Cheap insurance to me!). So it was down to physical inspection time...

    Simply put, the components on the CP won this comparison, hands down. Metal belt guard cage instead of plastic, both were fitted with Marathon 2HP motors, the CP had a MUCH nicer regulator, the one on the Husky looked like the thing I pulled off my 8 gallon CP last week. Not impressed. The CP regulator is well milled, and well executed...

    Now the piece d'resistance... Casually hand the cashier the 20% off coupon, scan, and $69.00 and change off! That paid for the extended warranty right there!

    So I got it home, and VERY carefully unloaded this beast out of my truck myself, wheeled the box to the shop, and carefully removed the compressor, including a little pallet then mount it to, out of the box and review the manual.

    Next step was to assemble this sucker. 2 wheels, 2 rubber feet and 1 handle, that's it. Next is the break in. Verify the break in oil is in the pump, open the drain valve. That's no cheesy Petcock valve down there! That's a nice smooth ball valve! Insert a male QD with nothing on it in the female, and fire it up for 10 minutes... Okay so I let it run 15, I got a phone call...

    Stop it, close it up, drain and refill the oil. Yep, just like the 8 gallon, the drain plug is in the worst possible position and next to impossible to cleanly drain this sucker. I made a little funnel gizmo out of aluminum foil to guide the draining oil to the catch pan, drain all the oil out I can, put plug back in. Next to no metal. Actually the drained oil looks really clean for break in oil!
    Put new oil in pump case to proper level, put stopper back in, and fire it up...

    Considering the 2HP motor, and nearly 30 gallon tank, this thing fills up REALLY fast. And it's quiet. Unlike the 8 gallon which I can hear all the way across the house, you have to stand next to the shop door to hear this one running...

    So the compressor is up, broken in, running, now what? Oh yeah, I upsized to support spraying right? Grab the spray gun, reduce some latex paint with some Floetrol per directions, run it through a strainer into the paint cup, connect the hoses to the regulators and filters and adjust the pressures, connect spray gun to the hose, and to the inside of the compressor box, well, get busy adjusting the spray gun... Okay gun adjusted, do the same with the Husky gun. Gun adjusted, and NOW the compressor kicks on!

    Drain back and clean the guns per directions. Done... Use blowgun to blow spray guns dry. Done...

    I am gonna LOVE not having to hear that little compressor kick on all the time any more, as is my wife, and my neighbors!

    I am a little hard pressed to know what to do with the 8 gallon though. It IS a nice little compressor for what it is, especially after the upgrades. But I need the space. I am considering selling this thing, or donating it to my church. The latter I think would be best. I need to check to see how that would work...

    This IS going to change my shop arrangements, and will likely mean the Thien pre separator has to go. But I can always put a baffle in the DC and call it good! I REALLY want my compressor next to the dust collector for space reasons. They are not something I interface with too often, just turn on, and off, and to empty...

    Can't wait to start spraying that ceiling!

    Congratulations! I hope you did a "break in" instead of the freudian slip.

      Sounds like a happy review. Nothing like spraying a finish, eh Db?
      I think in straight lines, but dream in curves

        Stupid auto correct... Yes it was to break it in.

        This thing is pretty big. It is occupying a space in front of an infrequently used shelving unit. I think I need to go through that shelving and pitch what isn't needed or wanted any more... Just to make more room in the shop!

        I'm not sure if I have mentioned how quiet this thing is. I am used to compressors being fairly loud beasts. This thing is quiet enough that I am pretty sure I can lean on the handle while it is running, and carry on a normal conversation...

        The break in definately did SOMETHING though. It smells like there might have been some packing oil ON the pump itself. The thing smells like warm oil. Probably a spill from when they loaded it at the factory...

          Interesting. I thought they made the coupons on the compressors verboten.
          I have a little blog about my shop

            They did! Somehow it slipped through... I bought a few other minor items that I thought the discount would apply to, but it applied to the compressor...

              To spray you need clean dry air. I routed the input air for my compressor head through an automotive air cleaner. Bought the housing from a junk yard. Run the compressed air through a regulator, drier, air hose to a 2 or 3 inch galvanized pipe that runs the length of the shop at an angle. Put a drain fitting on the low end. Air exits the high end goes through an air line to where I'm spraying, and through another drier and regulator. The two regulators and driers are usually disconnected as I don't spray much. Hate cleaning my spray guns. Good luck with your new compressor. When I got mine the old one went into the garage to inflate tires and run air tools away from the larger (80 gal tank, 3 cylinder head, 3 hp motor) stationary one.

                The rig thus far is...

                29 gallon compressor, on tank regulator, I regulate that down to 90 PSI before I hit my cheapie HF Polyurethane hose with it.

                Next is the HF cheapie polyurethane hose, 25' later is a HF regulator / filter / drier.

                Next is 25' Hitachi Polyurethane hose (how a poly hose should be!).

                Next is a disposable filter.

                Finally the spray gun.

                Not sure if I am getting moisture in the finish thus far, all I have sprayed with this rig is water based finishes anyway...

                For in shop use, I am planning on using either hard copper, or cast line. I don't see a need, or even a desire to go 2 or 3 inch, or even 1 inch for that matter. When I worked as a mechanic in a 12 bay shop, our entire shop was plumbed with 3/4" main to 1/2" galvanized drops, Filters in line, ball valve at the bottom of a tee placed at the lowest point of U below the filter to drop the line, and then up to the Quick Connector to the hoses. Chances are good I won't go that fancy. I mean that many drops and such. Probably run a short whip to 3/8" hard pipe across the ceiling to the post between the overhead doors, run my regulator / filter/ drier rig there, pull the U below that with the drop valve, and come up to a manifold. But that is a LONG way off. I have too many other shop projects that MUST happen first, like rebuilding the strong tie workbench / miter saw / mortiser / storage bench to provide better function, AND room for LOMLs freezer, and of course, my wiring / insulation project this fall... So hard piping MIGHT happen next year. Don't be in a hurry to see that project done though...

                  Sounds like a nice setup. I went the "other way" and upgraded to a turbine and gun (Fuji) and really like that setup. When you get to running pipe, you might want to check out the kits from this place:

                  It looks a lot easier than black iron or even copper.

                    I must admit to being leery of any sort of plastic pipe for holding pressure. I know Polyurethane hose is plastic, so it's just a silly little paranoia about plastics in hard piping I guess... I have heard a lot of good about it. Probably be a LOT easier working with the stuff...

                      If the price is not too high, they also have an aluminum pipe system (with plastic fittings). At least they used to.

                      When my builder told me that he would be using cpvc for water supply lines in my house I asked how much copper would be. He said he wasn't sure he could find a plumber that could run copper. I've since added a couple bathrooms with CPVCC and it is a lot quicker to make connections with. But I know what you mean about plastic and pressure.
