You'll have to pardon me for being nitpicky, but better information is needed to help. I have a couple of Eclipses (HP-CS & BCS) but not a Revolution. Hopefully we can figure out your problem with some very specific information.

First off, what do you mean by "nib"? I'm assuming that you're referring to either the needle cap, the nozzle cap, or the nozzle. I've included some images below to help you figure out which is which.


In this image, the parts from left to right are Needle Cap / Nozzle Cap / Nozzle / Airbrush Body












Once you've figured out what part isn't seating properly into another part, inspect both parts very closely for signs of damage. The front end of the airbrush is susceptible contamination from dried paint and you may have missed something while cleaning (or you may have jammed something into the threads inadvertently). Use a very bright light and a magnifying glass if needed. If any threads are damaged, you will need to order replacement parts. Hopefully, any damage is to something other than the airbrush body so it shouldn't break the bank if replacements are needed. Unfortunately, I'm in the US, so I can't advise you with regards to a parts supplier in Europe or the UK.

In all likelihood, your problem is due to dried paint or human error. I've never seen a threaded nozzle before but I can imagine it's a bit finicky to seat properly into the airbrush body. Assuming you can't see any damage to the threads, get some pure beeswax and lightly rub it on all threaded parts to act as a lubricant. A golf ball sized chunk will last you a lifetime. I use it on my Eclipse & Krome nozzles to make disassembling easier and to reduce bubbling in the cup.


Some additional considerations:

Check out Don's Airbrush Tips for an excellent review of the Revolution with some detailed images of the parts (including the photos above). You may learn something that helps you out.

If you can provide photos or more details regarding the exact nature of the problem (what do you mean by "wonky" and "not even"), someone here may be able to help.

Finally, how did you clean your airbrush? The problem with cleaning kits that are sold to newbies is that they can cause more problems than they're worth. Any sort of brush is very bad because even if the bristles are nylon, the metal handle can scratch the delicate parts (see image below). If you did use brushes, don't panic. I used them when I first started and although I did cause some surface scratching, there was no long-term damage.

These things are all terrible for your airbrush and should never be used:



The correct tools for cleaning your airbrush are an ultrasonic cleaner, cotton buds, and hobby cotton buds. You can get the ultrasonic cleaner on Amazon in the $30-$40 range (again, US prices so adjust accordingly). The goal is to clean with things that cannot possibly harm the surface of your airbrush while still getting rid of every little bit of paint. For cleaning agents, use the UK equivalent of Simple Green and 91% rubbing alcohol. You can also use airbrush cleaners, but the bulk generic stuff works just fine and is much cheaper. Here's some pics:

Cotton Bud


Hobby Cotton Bud by Tamiya. I use both 87105 & 87106 in the image below. The cotton is very tightly wound so they're great for tight spots. They can be bought at Hobby Lobby (again, adjust for your UK equivalent).



That's the best I can do without more information. Post more details and I'll check back later (or someone else may be able to help). Good luck
