So, I am recently back on my own after working for another shop the past 5 years. I am only going to spray waterborne products. My work volume will be fairly low, so I certainly don't need a super expensive rig. I might be spraying once per month or so. I was thinking of getting a pressure pot setup. If anyone has a better idea, let me know. Thanks in advance!! My budget is less than $1000.
I too do little spray work with ONLY waterborne prods !
Pressure pot is a good option for little runs, but not to neglect a very practical and very friendly usage....the 3M pot system.
I've been on both (P-Pot + 3M) and, use more my 3M since I do more custom or little series, but....I could live with out the pressure pot, would not trade my 3M system.
My 2ct !!
We used HVLP gravity-feed cup guns for years. Switched over to pressure pots a little over a year ago. We will not go back.
We have 4 pressure pot setups. One is dedicated to solvent-borne primer. One is dedicated to solvent-borne topcoat. One is dedicated to DNA-carrier dyes. One is dedicated to water-borne clear. They are all 2.5 gallon tanks. A one gallon container fits perfectly with the pick-up tube reaching a fraction of an inch from the bottom of the gallon can.
Having 4 setups eliminates lots of thorough cleanings between colors/coats/types of coatings. Even with our old cup guns we had dedicated guns to avoid cross-contamination between solvent and water as well as between clear and color.
Three of the four setups cost about $140 for the pot, regulators, hoses, and a cheap gun. (Found them on amazon: tcp global brand.) I changed a few of the guns to a CAT (C.A. Technologies) CP-FELCFM gun. Since the first three setups are solvent-borne materials, the inexpensive tank works just fine. I did change hoses on a couple of setups to get the length I wanted.
The water-borne setup was a little more expensive. We purchased a teflon-coated pot with regulators. Purchased hoses separately, and added the same CAT gun for MLC Agualente Plus Clear. CAT sells a complete stainless steel tank. We opted for a much less expensive option with the teflon. There has been a little bit of corrosion on the pick-up tube, but the clear finish seems to have cured over the corrosion and sealed it in.
The only issue that we seem to have is if we do not flush out the MLC material overnight. Even though it is a closed system, the material still thickens in the gun. The material in the hose lines seems to remain pure liquid. So, a quick gun-cleaning, if needed, and we are back to work.
After years of filling cup guns, the convenience of dropping a full gallon container into the tank is really a great time saver. I suggest you add a tank-liner (plastic insert) before you drop the gallon can in. This will catch any spills that may occur and avoids having to clean the tank.
Spraying is much, much easier. The gun does not have the added weight of a cup of material. The gun can be turned at any angle and even upside-down if needed. We can spray the far edge of the piece by simply leaning over, turning the gun upside down, and spraying.
For a grand I'd get a good gravity feed gun with multiple tips 1.1-1.5- 2.4 and a decent pressure pot system. You can do both for about 1K. Switching from pigments to clears will be your issue. I have two separate systems with both. I have two 2.5qt pot systems that can spray 20-30 doors front and back or two coats + before refilling. That's why I never upgraded to the 2.5gl system. You could also go with 2 pressure pot systems for around 1K and get a cheap gravity feed for stains. If you're only spraying once a month you'll have time to clean up well if you switch from pigment to clears.
I just ordered the 2.5 gal CAT pressure pot, and the h20 "cat pack" gun. Total was right about $650. The hoses were a bit pricey, and I can get them locally for about 1/3 of the cost. I'm also going to get a cheap cup gun for spraying primer. Should be a pretty decent set-up for under $800.. Thanks for your help guys! Next, I'm sure I'll need some help dialing in the proper settings! My experience is mostly with AAA rigs..

WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.
Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).
Libel: Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.
Improper Decorum: Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).
Advertising: The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).
Repeated Forum Abuse:
Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.
There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
