Iwata HP-TH

 

Full disclosure, I love Iwata. I purchased my first, the HP-BC2 for use with makeup EFX 33 years ago on the fourth floor of the original Pearl Paint in Manhattan. It was well over $300 (my first car around the same time was $200). I remember it was the fourth floor because I had to take a freight elevator to get to this exotic land of airbrushes, where no one but photo retouchers ever ventured, where a hunched, old man peddled wisdom. I still use that very same brush today and didn't feel to the need to get another until about two years ago when I wanted to try a gravity feed for quicker color changes (Iwata HP-AH)

Recent discussions regarding proper spray coverage for primer and large colors prompted the need for a larger pattern brush. After looking at the ABs mentioned in Paul Budzik's videos, even the lowest priced, the Iwata Kustom 9200 was out of reach for me in the low $400s. I couldn't justify that cost for something that would mostly be used for primers and clear coats.

I was wrong, both on the price and usage capabilities.

I've been buying a lot of stuff from Japan over the years, from books, cooking utensils and supplies to model kits, and there's one strange phenomena regarding what is exported and what is sold in Japan. A great example is a 1/16 Tamiya RC tank kit. The kits released in the Home Island market includes a Futaba transmitter, receiver, battery and charger. Same kit released for anywhere else has a transmitter shaped void in the packing, along with the teasing pages in the directions on how to setup the radio you're not getting.

Turns out Iwata does the same thing. There are the Japan market releases and there are the rest of us. In the US, The Hi-Line Professional TH is released as the Kustom K9200 TH. It includes a grip style moisture trap and beautiful aluminum case. In Japan, the exact same brush is released as the HP-TH in a simple cardboard box without the moisture trap.

The rise of Japanese shops selling to overseas customers has broken open many options, not just for wet stones and Nori, but a lot of other good things. I just bought a Hasegawa Scribber for $12 shipped as well as a Fujimi Claude for $8.80. This Iwata HP-TH was $154 on Amazon, in my hands in two days.

Okay, on to the brush:

As mentioned, you get a simple cardboard box:

Inside you get the body, two air caps (circular and flat patterns), a sizeable color cup with lid, a small tube of Superlube, instructions (Japanese) and a Iwata bumper sticker.

Great review Ausf!

I'm sold, though I don't think I need one at the moment. I understand you got this for priming larger models,
I'm curious how it does for getting in those nooks and crannies of smaller stuff.

Thanks guys.

Tom,

It's weird and definitely something I need to play around with. Yes it covers large areas, but it also covers all areas better in how the paint lands. I haven't sprayed anything smaller than Batman's utility belt pieces so far (did fine), but have some smaller stuff on the bench which will test it more. Instinctively, I wouldn't grab this to prime a 1/35 figure, but I have a feeling it may do a better job on it.

Art,
Ventilation is a must. At first I thought it was just the volume of paint, but on further testing, I've been spraying less paint in shorter bursts and the fogging is still there. It's probably more a by product of the blunt tip, since the paint/air mix is less concentrated than a fine detail brush.

I wonder...and not to take away anything from this product but...if one would blunt an old needle would we get the same effect?

Does this airgun have the adjustable air flow to create a fan patter like what Paul talks about in his videos?

There are two caps, one that sprays a fan pattern, which is the one I used on all testing. If you look at a closeup of the fan tip, there's two small holes in the 'arms'. The actual fan pateern sprays, between the arms, so the air flow is forcing a circular pattern to bend into a oblong pattern. That probably has a lot to do with the atomization and fogging too.

I bet you could get a similar effect with a blunt needle on a finer brush, but it would still have to seat in the nozzle without leakage and the point would have to be ground evenly so the spray would go straight. I can be done, but you'd be risking a needle or two trying to get there.

Paul's spraying is really the epitome of ABing. The man has skill. What looks like a simple pass is a perfectly timed danceand it's a real leap of confidence. I'm nowhere near that yet, but in my jerky, timid handling, I haven't had any pooling or pebbling yet, which I can't say wouldn't happen with my smaller brushes.

My intention isn't to push this gun, it certainly is a luxury compared to one all around brush. I'm just surprised by how much it does make a difference. I ended up buying a med-fine detail siphon first, then a detail gravity and then this. IMO opinion, the best aresenal would be a med-fine detail gravity feed and this one (or similar wide pattern).

I can see that fan pattern making a huge difference. I got a needle that has a broke tip, I may shape it up a bit and see what happens, I could always sharpen it more to a point once done playing.

You can see how blunt the tip is in the photo and it starts immediately outside the nozzle lip.

If you could somehow chuck the needle in slow moving drill, you may be able to grind it easily enough, or at least consistently.

Definitely worth a shot with a bad needle.
