Diy air compressor manifold ?

admin

Thinking of making one with some drop down regulators so I don't have to use the same regulator and change the pressure all the time. Anyone done this before?I am thinking of using some black pipe and some 1/4" npt steel bungs.Anything I need to know before doing this?Still trying to figure out my layout. But my compressor feeds the regulator which will feed the manfold. Off the manfold I want a direct line to the plasma. One to go to a regulator to drop pressure down to the powder coater. One for random tools.Torchmate 2x2 CNC with Flashcut CNC controlsHypertherm Powermax45 Esab ET220i Razorweld 195 MigRazorweld 200ac/dc TigTormach 770, Tormach xstechRazorweld, Vipercut/Vipermig, SSC Foot Pedal Dealer
Reply:You'll want to use weldable domed pipe ends on the manifold.  Attached ImagesDon’t pay any attention to meI’m just a hobbyist!CarlDynasty 300V350-Pro w/pulseSG Spool gun1937 IdealArc-300PowerArc 200ST3 SA-200sVantage 400
Reply:most of the stores that sell compressor parts have manifolds for like $20-$30http://www.homedepot.com/p/Unbranded...2820/203768023

Reply:The one from home depot dont look bad - make your own with pipe - size pipe is your choice - use pipe tees between nipples what ever lengthyou want - just plug the holes not used - i made a 6 drop manifold like thismy 2¢The main thing is not to panic or get excited Bobcat 250, X-Treme 12VS,  MM211Meltabo, Milwaukee,Porter Cable,Dewalt,MakitaVictor O/A, Ingersoll-RandEvolution Rage2, 40 amp PlasmaLincoln 225 AC/DC
Reply:Hey gamble, if you need a tank, and it will work, I have an AL tank frm a carbonator I do not need. AFAIK, they are supposed to be rated to 250 PSI or so.
Reply:I do not, but thank you. I bought a small one off ebay for $11 shipped. Going to use that for a bit and lay out how everything will work then maybe build one later. Thanks guys.Also why the dome ends?Torchmate 2x2 CNC with Flashcut CNC controlsHypertherm Powermax45 Esab ET220i Razorweld 195 MigRazorweld 200ac/dc TigTormach 770, Tormach xstechRazorweld, Vipercut/Vipermig, SSC Foot Pedal Dealer

Reply:Originally Posted by InsanerideI think to disperse pressure. No corners for pressure to blow out would be my guess.
Reply:Solid aluminum bar.Drill and tap for the fittings and mount it to the wall and call it a day....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:There should be no problem using a threaded sch 80 nipple with threaded pipe caps on the ends and bungs welded along its length.  Start with a 2" x 12" nipple or so for 4 taps.  That setup will handle up to 300 psi without any worries.  If you don't trust it, hydro it.Last edited by 76GMC1500; 12-10-2014 at 12:08 PM.

Reply:Nothing easier than drilling a 10" deep hole, right?My idea has material cost issues, though.  By the time you buy a sch 80 nipple, a class 300 cap, a class 300 bell reducer, and 4 class 3000 half couplings (they are steel so you can weld them) you're already in the hole $50.

Reply:I'd use aluminum like zapster suggested. I've made a few over the years. I posted some photos on something similar a while back. Drill and tap... done.http://weldingweb.com/vbb/showthread.php...coolant-mister

Reply:I can't drill a 10" hole. But I just ordered a aluminum block with everything drilled and tapped off ebay for $11 shipped. Will see how that works out.Torchmate 2x2 CNC with Flashcut CNC controlsHypertherm Powermax45 Esab ET220i Razorweld 195 MigRazorweld 200ac/dc TigTormach 770, Tormach xstechRazorweld, Vipercut/Vipermig, SSC Foot Pedal Dealer

Reply:Originally Posted by MinnesotaDaveOn small pipe in particular, it shouldn't be necessary - hoop stress is double longitudinal stress for thin wall pipe.(thin wall = a wall thickness of not more than 1/10 the radius, or 1/20 the radius depending where you read it)Example: a 4" diameter pipe, 1/10 of the radius = 0.2"
Reply:Originally Posted by InsanerideInteresting information.  I would think the pressure would go up when the volume or manifold size goes down. Guess im wrongOn a positive note, I have some 2"x2"x 7" aluminum that could be used for a manifold.  I need to figure out a dryer first.Gamble, please keep us updated on your progress. I have way more water in my compressor than I thought and would like ideas form wherever I can borrow from.
Reply:Originally Posted by GravelIf you haven't looked at this yet you should think about getting a Rapidair system or build something like it. Mine works great and I haven't had any moisture in my sandblast cabinet or my paint gun.This is a post by ZTFab with pictures of his setup. http://weldingweb.com/vbb/showthread.php...31#post4501131Originally Posted by InsanerideI read your posts and ZTFab's thread on the rapid air and saw it on Truck Universe when I had SPEED channel. I think Northern tool just had a sale for it in 1/2". It looks good and all but will it hold up to sparks from grinding and plasma torch?
