Airbrushes with good flow for large scale bodies

[glank27]

As i'm only into 1/12 scale, I sometimes find that my Iwata Revolution HP-CR with 0.3mm needle/nozzle is a bit on the low side when it comes to spray a whole large cowling like the one for example in a 126C2 which is a complete whole unit. Covering power is a bit on the low side, requiring some multiple passes with the risk of having an irregular finish. i tend to increase the pressure up to compensate, but would like to look for an extra airbrush for these kind of tasks, but that wouldn't cost a fortune though! As i'm quite satisfied with the Iwata performance i would like to stick to such brand. Paint to be used will be ZeroPaints with 2k clear.

This is the tool I use 99.9% for all my modeling 1/43-1/12 . But I also have a Paasche Talon that I nearly never use.
The H5 is just great and I use it with a 0.5 nozzle. Easy to clean and I use that brush for the last 15 years and just have my second set...so they are pretty tough

If you have to stick with Iwata, either the HP-TH https://www.iwata-airbrush.com/hp-th-hi ... brush.html
or HP-TH2 https://www.iwata-airbrush.com/iwata-hp ... brush.html

If you're more flexible, the Gunze Procon Boy LWA (which is based on the Iwatas, but half the price): https://www.hlj.com/procon-boy-lwa-trig ... -gnzps-290

I just googled Iwata HP-CR, seems it doesn’t comes with the rear end flow rate adjust knob. That’s the problem, not the 0.3mm nozzle size.

I have four Iwata CM series (three 0.23mm nozzles and one 0.18mm nozzle) for normal paints and 2K clear, and one Iwata HP-C plus (0.3mm nozzle) for “dirty job” 2K prime.

As long as I set the compressor pressure to 20 psig and release the rear end knob somewhat, all three 0.23mm ones are very good for 1/12 car parts even the whole body parts like in your project. For your reference, I used them to complete Tamiya 1/12 Carrera GT a few years ago. Spray at ease, very smooth without any struggle.

I haven’t used the 0.18mm one for 1/12, so I can’t guarantee there.......

If possible, bottom line is to get one with the rear knob. You will want to regulate flow rate mainly by the rear knob not the compressor pressure. Too high of a compressor pressure will ruin your uncured paint especially for larger surfaces.

Ok, one last real world experience is, the additional fancy so called “fine adjust” knob on Iwata CM-CP 2 front end is a totally waste....... looks fancy though……

Corse control by compressor pressure and fine control by rear end knob is all you want.

Don’t go crazy to 0.5mm, not smooth enough. IMHO, 0.3mm is too big.

Hi,

I’m using a HP-TH 0.5 flat pattern for about 15 years and love it!
I wanted another one for the primer and paint and also have a GSI CREOS PROCON BOY 0.5 flat pattern and a Sparmax DH-825.
I really recommend those airbrushes which are perfect for 1/20 and 1/12.
I also have since 2 years I think, the stunning and cheap 0.3 Meng flat pattern which is just awesome!
All the paint job of the 1/20 Eagle Weslake I’m currently building is done with the Meng as some parts (nose) of the 1/12 Ferrari 312F1 1967.
Please find below 2 pics with HP-TH, Sparmax, Meng and Tamiya.

I hope that will be of some help.
Don’t hesitate if you need more information.

I graduated to the Iwata LPH-50 HVLP for large scale when I was doing Tamiya's 1:12 935. Just to big of a body to use any air brush on. The 50 can be had with three different tips/needles. .4mm, .6mm or 1mm. I bought all three and use them all from time to time. You can a adjust the fan form 1/8" to 4". It is also a true fan and not a circle pattern so you get a much more even layer of paint.

It comes with a large gravity fed 120 mm cup which I have only used once. You can buy and attachment that lets you use standard siphon feed airbrush bottles which is what I use most of the time. It does require a regular compressor because it is a high volume/low pressure brush.

It looks like a touchup gun and I suppose it could be used that way, but I came across it when I attended a seminar of mural painting by Craig Frazer. He used it almost exclusively for his art work. It is my primary gun but I use smaller Tamiya/Iwata's for the little stuff. This could do it, but it is just too big to get into small spaces.

Oh and it cost about the same as two regular brushes, but then with what you are doing, you would never get the wide pattern that this can provide.

Check out the GSI Creos Mr. Procon Boy. Funny name but great for larger surfaces. Has a fan adjustment like larger air guns. $150 on Amazon.

Here's what I use for larger pieces. It's a Neo for Iwata TRN1 modified with a larger cup and 0.5 nozzle/needle. It's not a very expensive airbrush, and it sprays really nice.

Cheers,
Greg

Paul does a great job of explaining the gun. As I mentioned and he didn't I prefer to use the "bottle adapter" kit which makes it a siphon feed of of standard airbrush bottle. I have multiple size bottles.
