Took apart the metering valve looking for clogs completely changed the media and now it gives spurts of media. I'm going to calabrate the air pressure and metering valve like you described.

I have two holes about 1 inch in diameter… one to drain the media plug and the other a media pickup hole the goes from there into the top part of the shelf of the cabinet in the front.

    We use a 1/4" nozzle and then match the orifice to the output specs of the compressor. The nozzle (assume this is what you are calling the tip) plays a roll in controlling the spray pattern but the orifice size (ID) is really the most important component in terms of getting good and consistent flow. We would need more info to help you diagnose the problem. Also if you are using the HF gun that came with the cabinet, that thing is pretty bad. Have you replaced the siphon tube with a metering valve. That will work wonders. Hope this helps

    In theory can I use a bigger fitting that attaches to the drop door? And what is the best size for the part coming off the tee that the hose and valve attach too? I plan on welding a bigger pipe fitting to the door so there's a bigger hole for the media to go through.

  • @partswasherupgradekit6028

    Bigger is not always better because the flow of air will effectively stop when volume becomes too great. If you go to a larger pipe fitting to attempt to increase the draining of the hopper you may find that improving one aspect of the valve renders the rest of it highly ineffective. We tested many combinations before we found what functioned the best. All the pieces need to work together. Hope this helps

    Here's some answers to your questions: 1) 3/8" ID air hose is the standard 2) 1/4" fittings with 3/8" barb are standard (and no - they are not too small) 3) Nozzle ID should be approx 2x the orifice ID 4) orifice size needs to be tuned to the CFM of the compressor 5) black diamond (coal slag) and aluminum oxide would be good media to try. Grit size depends on the size of your system (CFM and orifice size) and the amount of rust you are needing to knock off hope this helps Best regards The Team at best Tool Upgrades

    ​@@partswasherupgradekit6028 Wow I was hopeful you guys would answer but didn't really expect one because most businesses are to busy to answer. I put mine together and have the HF Gun on it and one of the Y-Looking guns, sorry not yours, and I should be trying it out after I get some media. Here's the information I have on my current set up; * Competitors Gun - Black Nozzle opening is a #1 drill .228" (5.8mm). - Air Inlet #23 .154" (3.9mm). ** The harbor Freight Gun - White ceramic Nozzle opening is a #11 drill .191" (4.8mm). - Air Inlet of #39 .099" (2.5mm). *** The compressor is a Speedaire 4B247B with a max PSI of 135 - Displacement CFM of 14.1 - Free Air of 11.2CFM @40psi and 9.6CFM @60 psi. If anyone can make sense of this you guys can. PS I have a 60 Gallon SpeedAire Cast Iron tank. The motor is 240V @ 15amps 3450 rpm. Sorry for all the specs but I used to be an Aviation Electronics Technician for 42 years for the U.S. Navy and Contractors and I found it best to give all the information if you want a effective answer.

    You want 3 to 4 threads showing between the brass lock nut and the black hex portion of the body of the orifice. From there you can turn it in one turn or out one turn. This gives you the final fine control of the spray pattern of the media as it exits the orifice. But you do this adjustment LAST after everything else is dialed in. Hope this answers your question. regards. The team at Best Tool Upgrades

The metering valve needs to be dialed in as described in the video because your setup will be a little different than another one. It only takes about 5 minutes to dial it in and really never needs to be changed unless you change your compressor or go to a very different kind of media. Try the procedure we have described and let us know if you have any questions. Happy blasting !!

    @Doug: Sorry to hear that you are having issues. If you sourced parts yourself from the various internet sources, it is possible that you have parts that are not quality pieces. For example, please see our video kzread.info/dash/bejne/gHt51rCsaLS9oNo.html where we describe a very poor quality Chinese knockoff of the gun that we sell on our website partswasherupgradekit.com. Without knowing if the parts themselves are up to snuff, it is hard to diagnose the problem. It is possible that you have the wrong orifice size in the gun and that orifice is not matched to your compressor specs. Or the nozzle ID may not be matched to the orifice ID. Get back to us if you continue to have problems and we will do our best to help.

    Thanks for your comment. The foot valve we supply with our kits is sized to work extremely well with the size orifices we supply (3/32 and 1/8). Our products are meant to support the home garage guy and small production shops. We have sold >1000s of kits and our customer feedback is enthusiastically positive based on their great experiences with upgrading their blast cabinets with our products. With very large orifices, 5/16" etc., yes, more air flow is needed across multiple components in the overall system, but these large size guns are typically found in large scale, factory style production facilities that run their equipment virtually all day and every day. That is clearly not our market. Again, thanks for your comment. Happy blasting!!

    Replying to your comment, as i also am under the same undertanding! However... I have been thinking to have a pedal (i used to blast as a job commercially, so im used to it) annnd what/how i came up with was.. What if i run a 12v 3/4 solenoid valve so the "foot pedal" is electric actually(running a 13hp honda to a 3 cyl pump). I have 0 idea how it was done in the day (way back) i just did it, i wasnt thinking to ever build one. I have seen that.. apparently the lowrider community, has some what they call "Fast" valves, im thinking that might be the ticket?! Curious to hear feed back :) / I do know you can buy a mechanical 3/4 valve for several hundred from like one place, so far that i see.. But you can get one if these elec valves for half that, or less and they are "around" . Its all cloak and dagger trying to find orifice size on valves for the most part every pic of every valve everywhere isnt shown just right so you can actually SEE! Uh huh tells ya something right there i think! Another reason why i think the "fast acting" must be a large orifice ??!
