Comparing An Airbrush Fan Cap To A Regular Nozzle

[@reylen3883]

I hope that you make a video of you just painting a car or a kit from start to finish.

[@bobrivett7645]

That would cool.

[@jenniferwhitewolf3784]

These are so good, and so affordable, I may well be buying a second Swallowtail, so I keep one dedicated to fan tip. If any reader is hesitating, don't. This is a great airbrush. I also own expensive Iwata, and been airbrushing almost 60 years.. This passes my approval and earns my full endorsement.

[@cyclemadness]

I'm a rank beginner at 52 yrs old. You give me high confidence that I bought the right tool. I don't see needing the fan cap, as I only paint board game miniatures. But, but if in your expertise you'd say otherwise, please let me know.

[@jenniferwhitewolf3784]

@@cyclemadness You'll be fine with standard tip. 👍. The fan tip helps with really large surfaces, like O and G scale model RR cars. Small stuff, a regular traditional tip is perfect.

[@jenniferwhitewolf3784]

Suggestion when spraying metallics, fan or regular tip.. Apply paint from one direction only. I'm right handed and shoot left to right. Always spray your overlap traveling the same direction. the microscopic metallic flakes will lay different in the resin when sprayed opposite direction. By always spraying in one direction of travel, the flake lays the same across the whole surface and under bright light will have a smooth evenness in the flake reflectivity.

[@ClarenceObert]

Thank you for this tip. Will come in handy.

[@bobrivett7645]

I learned that same technique when helping friends do custom paint jobs on cars. Never thought about it with hobby/model paints and plastic models like cars 1/24 scale, etc. Makes sense though.

[@xaviermontalban717]

The same applies to pearlescent paints

[@vasili1207]

But at the end off your stay pattern if you don't understand spray past... this will leave you with thin paint at one end and thick paint at other end... Always spray past

I just ordered my airbrush with the optional fan cap. This is going to be a game changer, my friend.

[@barbatosrex9473]

It's a great airbrush, you'll love it

[@Avalanche523]

Great information on fan cap vs no fan cap. Thank you.

[@bobrivett7645]

I bought the fan cap when it was 1st realized. I plan to use it my multi-engine 1/48th scale WWII aircraft. I figured it would be more efficient way of priming the body & wings, less paint better coverage. This way I could preserve the small panel lines, rivets and other minute details. I think BR proved that when primed that car body, I could still see the variouse panel lines, really well afterwards. Plus that black primer is awsome.

[@eileencollins3126]

Great video, as always! In my working days, I worked for a very large airplane building company, and went to paint school to learn to paint airplanes. The spray guns we used were giant by comparison, but the principles were the same. With a Fan Cap, to get the most even coverage of paint, it is basically a 50% overlap on each pass. If you point the center of the airbrush at the edge of the coverage on the previous pass, the applied paint thickness will be the most even on the entire piece.

[@randyrichey6931]

Just used the fan cap on my swallowtail spraying clear coat, was really nice !

[@bobrivett7645]

You I was looking for a replacement paint shaker, my old one had died, and I didn't want to buy the same one again. I found this channel of BR testing that 4-eyes paint shaker, while it was twice as much money than my old one, I pulled the trigger and bought it. It's really nice, doesn't vibrate my work bench like my old one. I've had for almost 6 months now and no problems. Will see how well it holds over time. Thank you Mr. BR

[@BrianPost--ni6qs7yc4w]

I bought that same model, mine didn't have an option to get an extra top rubber though. Haven't had any issues with it. I've found that it's better to pay a lilte bit extra & buy a good product once!

[@padrespeaks]

I'm gonna knit pick so hard here, but I swear I mean well. If an airbrush doesn't have a fan cap air adjustment, you get what the demo shows after a few passes: overspray. The paint and air have to be dialed in so perfect, or else you get irregular patterns. I'd call it a "fan cap style" rather than an honest fan cap. I own a PS-290 by GSI Creos and its nearly impossible to get even stynylrez to get down nice and flat and even. Iwata makes relatively affordable spray guns with a fan cap adjustment that yes, need a beefier compressor, but I'd invest in that and be able to use my airbrushes. Having said all that, I love the channel and keep up the great work! You taught me a lot and no doubt you'll teach me more.

[@ClarenceObert]

I too have the PS-290 with fan cap and I had problems laying down stynylrez until I strained it through a 190 micron screen. Once that, I thinned it approximately 10% and it sprayed fine. Maybe I just got lucky? I do like the swallowtail, but I find I like my PS-290 fan cap better for that application. So, for laying primer on large areas, I'll go to my 290, for the rest, I'll use my Swallowtail. Unfortunately, that leaves my Iwata Revolution relegated to storage. BTW: I only use water based acrylics so I can't speak to how well either performs with lacquer or enamel.

[@JuanM759]

Thanks Bob

[@dwgeer13]

Thank you I learned something new I didn’t know what a fan cap does. You make me understand more about what a fan cap does

[@yotsie32]

I can say this, as a long time Grex user (.5mm fan cap) your Swallowtail with the fan cap is now my go to for car kits. I've gotten better coverage with less product used and the trigger on the Swallowtail is butter smooth. I will still use the Grex from time to time, but the Swallowtail is my new workhorse.

[@timhedge3416]

I like the fan cap but I really like the black primer

[@Marshal976]

Thanks for this mate, I had always wondered but now I can see the differences between the nozzles. I think its like having round brushes vs flat fan brushes in hairy brush painting.

[@nelsonolivierjr3994]

Man it's so amazing to see the difference between an Airbrush priming and spray can priming. Cans just push out way to much paint and if they cut that in half like those Krylon foil paint cans which I used for my Saninju it lays down a nice thin payer of paint and looks great. Just to spray a Matt Balck over a gundam body you have to make sure you got all of your movible parts safe from the paint cause it will ruin them.

Good explanation, thank you, Robert.

[@ForwardMovingDesigns]

I have the ps290 was gonna buy this swallowtail to use the fan cap with the .7 needle nozzle but thanks for pointing out it only works with the .5. I do smart repairs and love trying new guns and brushes out. The ps 290 in a .5 doesnt distribute the mattalics in a way to match the general look of car paint when blending. They clog abit and are too close together. Had high hopes for the .7 with the fan cap. My smallest spray gun is a .8 and does the job so was hoping this swallowtail with the .7 and fan cap would get the job done on tiny blowins. Oh well hopefully one day they will make a fan cap to suit all the needle nozzle combinations. Luv the channel btw.

[@CharlieHague-m8u]

Informative video, as always. Just a note that how the fan cap is oriented will make a difference in the spray pattern. This is something that ccx an make an impact when spraying, especially for beginners to airbrushing

[@BrianPost--ni6qs7yc4w]

I've got a full size fan cap air gun that came with my fullsize air compressor. I use it for spraying the BITTYDESIGN Liquid Mask on 1/10th & 1/8th RC polycarbonate body shells. This is so I don't need to filter it for the smaller airbrushes for the exact same reason as your old black primer.. A 1/8th bodyshell only takes a couple of minutes to get the proper coverage. The smaller airbrushes was roughly 15 to 20 minutes as you can only laydown thin coats & need to allow them to dry between each coat.

I've been having trouble with black and grey stynylrez on my 0.5mm ace. Getting tip drying and clogging issues. Just ordered a swallowtail for the 0.7mm setup. Hoping that helps push this stuff through more consistently. The primer is a little on the thick side. I will definitely be switching to mr surfacer if i continue to have issues. If the swallowtail cant do it, then it must be the primer.

[@ClarenceObert]

Stynylrez will give you tip dry like crazy no matter what. At least that's my experience. That's just the nature of the beast with water based acrylics. I cut my tip dry down drastically by straining it through a 190 micron screen, and thinning it 10%. Hope this helps. BTW: I got a lot of clogging/tip dry with the .5mm fan cap with the swallowtail. Switched to the .7mm and it cut that down drastically. I'll use my .5mm fan cap PS-290 with stynylrez from now on. But, that's just me. The swallowtail, to me, is more comfortable over an extended paint session.

Keep in mind to make a fan cap work effectively you have to have an adequate cfm output. Its just my opinion but I have found the fan caps on airbrushes to be a gimmick. If there is no air adjustment knob to the fan you cant fine tune the pressure/pattern for the material you are using.
