spbubba Posted November 6, 2017 Report Share Posted November 6, 2017 I am using a Iwata-Medea Revolution CR Dual Action airbrush to paint cranks. I am a total rookie and this is my first real issue. When i tighten the nozzle cap finger tight it restricts paint flow. If i loosen it half a turn flow returns but pattern is affected. I have replaced the nozzle cap and needle without improvement. Help please. Quote Link to comment Share on other sites More sharing options...
BobP Posted November 6, 2017 Report Share Posted November 6, 2017 I’ve never heard of an Iwata problem with parts fitment, assuming you are using the correct parts, so my first suspicion would be a buildup of dried paint partially clogging the end cap hole. Dried airbrush paint doesn’t clean out entirely even when flushed with a solvent like acetone, so you need to disassemble and soak the airbrush in a dedicated airbrush cleaning solution overnight occasionally to soften and remove those deposits. That’s what I’d do first before thinking a part was damaged, misaligned, or the wrong part. Quote Link to comment Share on other sites More sharing options...
mark poulson Posted November 6, 2017 Report Share Posted November 6, 2017 I soak my disassembled air brush overnight in Createx Air Brush Restorer. I keep in a wide mouthed pickle jar, and it can be used over and over. http://www.coastairbrush.com/products.asp?cat=59 Quote Link to comment Share on other sites More sharing options...
spbubba Posted November 6, 2017 Author Report Share Posted November 6, 2017 I will give it a soak and see what happens. Thank you both for the input. Quote Link to comment Share on other sites More sharing options...
Musky Glenn Posted November 7, 2017 Report Share Posted November 7, 2017 Could the needle be set to deep and not allowing the cap to tighten correctly? Quote Link to comment Share on other sites More sharing options...
BobP Posted November 7, 2017 Report Share Posted November 7, 2017 The needle on a Revolution fits into a very small Iwata nozzle so unless it has been forced and split the nozzle, it’s fairly fool proof. There’s always the possibility that a replacement part was the wrong part for your model. If you have the original parts, I’d refit them to see if the problem persists, just to check. If it does, I’m betting the airbrush needs a soak in restorer. I’m pretty good about cleaning mine with acetone between sessions but after a few months, a soak in restorer still removes an amazing amount of gunk. 1 Quote Link to comment Share on other sites More sharing options...
Musky Glenn Posted November 8, 2017 Report Share Posted November 8, 2017 The revolution does have a chucking nut on the needle that would allow the needle to be set at a depth the tip would bottom out on needle before it tightened all the way down on the threads of the tip. This would cause it to act similar to having a build up of paint. Quote Link to comment Share on other sites More sharing options...
spbubba Posted November 9, 2017 Author Report Share Posted November 9, 2017 I soaked the brush overnight and reassembled it this morning. I will have a chance to paint some baits over the weekend. I will let you know how it goes. Thanks to each of you for taking the time to help. Quote Link to comment Share on other sites More sharing options...
Musky Glenn Posted November 9, 2017 Report Share Posted November 9, 2017 Did you get any old paint out of the gun after soaking? Quote Link to comment Share on other sites More sharing options...
spbubba Posted November 9, 2017 Author Report Share Posted November 9, 2017 I did get some paint out after the soaking. I am hoping that solved the problem. Quote Link to comment Share on other sites More sharing options...
Musky Glenn Posted November 10, 2017 Report Share Posted November 10, 2017 Dried paint is usually the problem but you just never know when that once in a life time problem happens to you. Good luck, let us know if that fixed the problem. Quote Link to comment Share on other sites More sharing options...
