Well, since I am using spray cans as I have no air to use my spray gun that should be par for the course........ ;)

Edit: so I sprayed the frame with primer. One tip I should mention, if you're spraying a rectangular tube you always start by spraying the 4 corners of the tube length wise. Once you do that come back & spray the flats length wise. This helps to keep any runs to a minimum. Round tube you're just sol as I know of no good ways to keep runs at bay other than a lot of light coats....

Painting round tube:

position vertically where possible. Heat to avg room temp prior to painting, prime and paint in several light layers with even distance from the material and NEVER STOP MOVING.

Powder coating doesn't run...

That was tooooo easy! Kinda makes the wall look like part of the vatican. lol

I can't believe that you left that hang there like that........it could lead other painting projects astray with it's lofty position - the other projects may look upon it and strive to look be like the "cool cover".. :o

OK, so a little more progress today. I laid the final top coat on the tank and the frame today. I also received a critical component this evening from Grainger that I had ordered online several days ago. It is a 3/4 x 3/4 check valve with a 1/4" port built into it. When assembling a compressor head onto a bare tank you should make sure the tank has a check valve installed on the intake port into the tank. Being that my tank was used prior as a storage tank it did not have one. I believe the theory on this is that start up is easier on the compressor head. Two items are plumbed into that 1/4" port on the check valve. The first is a vent from the crank case on the compressor and the other ties into what I believe they call the unloader valve on the pressure switch. This head also has a by pass built into the top of the cylinder heads and is used for continuous operation such as a gas or diesel powered unit. We will not be using that function as this is an electric powered setup so I will just be capping that line connection off at the top of the head. However, if it were to be used with a gas or diesel power unit once the tank reaches pressure it opens these valves on the top of the head which act as a by pass allowing it to run but not create pressure thus keeping heat from building up under continuous power. So tomorrow I start the assembly process, I am going to pick up some hockey pucks after my morning work out to use as feet for the base of the frame.

Good idea on the valve.

TexasRedNeck · « **Reply #59 on:** January 22, 2016, 07:05:45 AM »

I get the check valve part but why the crank case connection to the 1/4 port?

stlaser · « **Reply #60 on:** January 22, 2016, 09:15:52 AM »

Good question TRN, & one I'm going to ask manufacturer today. It was in that pesky Eaton instruction manual. I re read it like ten times as I didn't understand why we would do that either. Only thing I can think of is maybe due to this being a 2 stage pump the crank case builds pressure? Not really sure but when I built my last compressor from them it was a single stage & I did not do that. If Don sees this & has a minute he could look at how his is plumbed (pretty sure he has a larger 2 stage unit from them) & confirm this is correct. Although his may be different as this is single cylinder & he's has a couple cylinders on his I believe. One other thing worth mentioning was that in the instructions there is supposed to be a 90 degree compression fitting on the compressor head output that didn't make the build apparently. Not a big deal as I can get one local.

I also tried looking at Eatons site (picture section as Don knows I like pictures) & the one poor picture I could make out that vent tube went down towards the area where the head output went. Couldn't see where they ended up due to frame being in the way but it appeared to match the instructions.....

On mine, that tube runs from the crankcase to the intake side of the head, just like the pcv on a car, sucking out the blowby.

Ken, is yours a 2 stage & one or more cylinders?

Edit: & just for tickles & giggles I just went out & looked at intake side of head & air cleaner assembly. There is no provision for that 1/4 inch line there....

KensAuto · « **Reply #63 on:** January 22, 2016, 10:13:16 AM »

2 stage, 2 piston, but I forgot to mention it was a gas compressor converted to 3hp electric.

stlaser · « **Reply #64 on:** January 22, 2016, 10:20:33 AM »

Sure that line isn't for the open by pass for continual operation? This was a gas unit.....

Edit: that line doesn't appear to have a check valve in it unless it's built into head. So if that is just a breather tube how does that work? PVC is essentially a check valve correct? So you would think this line would have one too.

stlaser · « **Reply #65 on:** January 22, 2016, 10:26:26 AM »

I take all that back, those two plugs on top of head I think are for the by pass when it was a gas unit. Sound right?

JR · « **Reply #66 on:** January 22, 2016, 11:01:57 AM »

It could also be a line for pressure feeding oil.

stlaser · « **Reply #67 on:** January 22, 2016, 12:27:20 PM »

Ok, spoke with Eaton very helpful. Long story short since it is not a continuous run unit I leave vent on crank case alone. The way the manual read it appeared to say to connect it to the check valve on the tank but it was referencing or it meant to reference hooking it in with the unloaders on top of the cylinders. As I am not using those they get capped off & vent stays open to atmosphere, which makes a lot more sense....

Edit: Proof for Ken..... ;)

The part they don't specify is when they say check valve third bullet point what they are referencing is a part of the pilot valve that you use when operating on a continuous basis such as a gas or diesel engine. The only check valve I have on this system that I am aware of is the one installed in the tank which they referenced in the second bullet point. Having these right there together with my feeble mind made me believe we were speaking of the same valve..... And for the record Don pics would have been very helpful! ;D

KensAuto · « **Reply #68 on:** January 22, 2016, 01:02:30 PM »

Hmm. Not sure how that works (mine). Don't see a check valve, but a local (competent) compressor shop converted this one.

stlaser · « **Reply #69 on:** January 22, 2016, 03:26:56 PM »

stlaser · « **Reply #70 on:** January 23, 2016, 04:58:21 PM »

OK, so yesterday I spent most of the day picking up pieces here and there to finish the build. Then ran around to girls basketball games and tournaments most of the morning. So this afternoon I started piecing together the build. Started by adding a ball valve to the bottom drain which I will most likely swap to auto drain in the near future. Then mounted the hockey pucks to the bottom of the frame and went ahead and mounted tank in frame. Finished by loosely bolting the electric motor in place and opening up the wiring to see what I was dealing with there (four wires coming out of the motor and a diagram of which ones to splice together for CW & CCW rotation) pretty straight forward. Was going to mount pump but that meant dragging out engine hoist and I wasn't having it today......

stlaser · « **Reply #71 on:** January 26, 2016, 10:28:15 PM »

OK, so Monday I hoisted compressor head into place.

Finished up the plumbing

Then wired up the unit today along with new breaker in the box an new 30 amp plug and receptacle. Slapped on the new belts & we started making pressure only to find a leak on the 3/4" output compression fitting and no replacement ferrels local. >:( Will pick one up in morning and then dial in the pressure switch settings.......

I agree, plan is to eventually run 2" black pipe around the ceiling of the shop with several convenient drops to add to the capacity....

stlaser · « **Reply #77 on:** January 28, 2016, 06:10:30 PM »

So I installed a 3" leveling kit on an 08 Tacoma this morning. Compressor functioned flawlessly. It's quiet & had no problem keeping up with my impact. At some point I will update the build with a guard around the belts & pulleys. For now I need to get this wired & moved into its permanent location under my smaller loft.

OldKooT · « **Reply #80 on:** February 22, 2016, 08:58:37 AM »

Looks nice.... I have a electric unit as well. I have mine plumbed with a unloader valve so I can set it to run continuous. Although my unit will easily run along with most everything I ask of it, sometimes if sandblasting hard with a large nozzle I will set it to continuous so it doesn't have to start and stop. That works out very slick when blasting, and I never see a drop in performance then at the sandblaster.

After running my project a year, my only planned change is to plumb the air intake outside...someday.

stlaser · « **Reply #81 on:** February 22, 2016, 09:11:31 AM »

Yep, no continuous run for me. I doubt I buy a sand blaster living here in suburbia. I had one at the farm for years & used it twice I think. Big jobs I always took to commercial guys. I finally moved it under small loft into its permanent place over the weekend & stopped at HD to buy the wiring for it & the wall outlets. I've used it several times w/o issue, even when running big impact it doesn't seem to even work it unlike my last smaller single stage unit.

Hey Koot, doing two things here

1. Messing up Shawn's thread...pay back kinda thing

and,

2. I haven't found any of those hit and miss engines. Any ideas about how to better look for them? I want to buy one and get it running down on the farm. That thing is just too cool not to own!

Don... I might have a a few for sale/trade in a few weeks. I am working a deal now to buy a mans collection in the near future. When I do...before I sale any off I will post them here.

And yeah two stage compressors are the way to go for a hobby shop/business. I should always pay someone to sandblast, but the local guy that does it is in jail again.

I am riding in a way rural area where everything everyone owns is on display on the porch or yard or in the barn with the walls partially missing. Found some cool tractors so far and get this, two 1964 fast back barracudas!

No kidding the farm across the street was auctioned off a couple months ago. The new owners were in there clearing off the mess, and right there is a pile of old cars and trucks in the barn were two fastback Cudas. Those huge bubble rear windows are in perfect condition. Now they are sitting beside the street. I'm trying to find out...

I know first hand how you find the darnedest stuff in old buildings/barns. Sounds like your weather is nice enough to go riding. We have had a few warm days in the 70's. But that just made every country road a mud bog...which isn't without it's fun moments.
