IWATA REVOLUTION HP-TR2 - THE AIRBRUSH SHOW EP08

[@PixelGod240]

I love this gun!!! I thought I'd hate the side feed but it's amazing for detail pre shades on gundams!

[@PixelGod240]

FYI I strongly recommend the .3mm version nof this brush as it atomize paint as well if not better than Hp-c+. Point of that side feed for us modelers is to be able to see especially for pre shades which this brush is amazing for with trigger stability.

[@alanlemire4347]

I have this brush and don't use it very much because the Paint cup falls out all the time. Is there a fix for this or am I doing something wrong?

[@scalewarmachines]

That’s very unusual. Does it happen on both sides?

[@omerthe3rd1]

How about the compressor? Is it included in the kit?? And can I use acrylic colors in it? Which is water based paint

[@scalewarmachines]

No compressor included. You can happily use acrylics which are generally water-based paints.

[@jnrmack]

You can also use 1oz/2oz high strength translucent side feed bottle for larger volumes of paint or use to hold cleaner.

[@sarmy3d]

When diluting primer, is there a reason you used lacquer vs acrylic thinner? I'm used to using Tamiya Gray in a can.

[@scalewarmachines]

Just seems to be a bit more effective generally - especially with primer - but it stinks to high heaven.

[@sarmy3d]

Ah thanks. That's what I've heard about the stuff. Just built a new spray booth, might be interesting to see how it vents that stuff out. It doesn't damage GW polystyrene plastic does it? I saw the "gentle on plastic" part of the description and got scared.

[@RideShagbark]

Was kind of hoping for some details on why you'd go for this over the cheaper Iwata NEO TR2.

[@scalewarmachines]

Can give you a couple. It's a better quality item, we run the Neo Trigger and it is harder to clean, we have had one part break so far on the Neo (nozzle broke from the thread - easy enough to replace) and it also has an annoying sticking valve which is affected by the tube extension that goes through the Neo Handle grip. Annoyingly, sometimes the Neo can leak air via the handle/valve, unless it is adjusted "just so" to a sweet spot. The parts breakdown is much easier for cleaning on this featured brush. You get what you pay for. So far this trigger gun in the video has been bullet-proof. The Neo less so. Remember, trigger guns can be harder to clean and keep running than a "normal" lever airbrush, so get some idea of usability and user-serviceability first. Iwata products are first-rate and the Neo ones are definitely entry-level and less well-engineered but still a great starting point for the price.

[@RideShagbark]

Thanks for the reply. Originally, I was comparing/deciding between the Grex Tritium.TS5 to the Iwata Neo TRN2. Looks like I should really be making that comparison between the Grex and this Revolution HP-TR2.

[@jeffslade1892]

I notice the Neo TRN2 has gained the peephole of the HP-TR2 and is no longer identical to the Sparmax GP. One advantage of a side-feed trigger is the ability to shoot from a siphon feed bottle with a custom mixed colour of enamel, mixed in bulk and stored in the same jar; where the hard wearing and weather proof enamel is required e.g. guitar or motorcycle. Enamel and other such durable paints do not have the runny consistency of acrylic. The 0.5mm jet/needle is a medium size, the size of the jet/needle is to suit the consistency of the paint, some thicker fast-drying paints will quickly block a fine jet/needle. The 0.5mm needle will go down to a 0.5mm line and up to 1.1/2-inch; the TRN2 has a back stop to regulate the paint flow. Fine jets like a 0.2mm do not seem to suit enamel, either the paint has to be thinned too much or the pressure increased causing spidering. The fan pattern size is controlled by the air jets around the paint nozzle and the shape of the end cup, and can be regulated to some extend by the air pressure used. The needle/jet alone does not control the paint area, for example the Badger 200 Detail uses a 0.3mm to produce very fine lines, whereas the 'general purpose' Badger 200NH uses a 0.7mm and yet is still a medium-fine spray pattern. It's the construction of the spray head. I notice the instructions from Neo for the TRN2 do say not to remove the jet unless absolutely necessary. Presumably they know the jet is brittle. As with any very small fine thread, they should only be tightened with great delicacy, like inside a watch. My only complaint with the TRN2 is the pistol grip is too small and only suitable for a young child. Fortunately there is a hole in the hilt to insert half a clothes peg as an extension.

[@sarmy3d]

How would you rate the HP-TR2 vs the TR1? I'd like one for priming and base coating 40k minis and vehicles. Would the .5mm be too large for any fine work?

[@scalewarmachines]

Both are good for that task but the HP is the better one for the reasons listed in other replies to comments and so is more costly. You won't be able to do that much detail with the combination of a trigger layout and that needle size though.

[@sarmy3d]

Oh sorry I mis-typed. I meant to ask about the HP-TR1 vs the HP-TR2. Is there much of a difference in practical application or versatility between the 0.3 and 0.5 needle sizes? I also saw the MR Hobby makes something very similar that has a wide fan head. Does Iwata make anything like that for this model? Again, I'm most interested in priming and throwing down base coats.

[@scalewarmachines]

The bigger the needle combo the better it will be at throwing down an even and covering primer coat. But you are right, if solely focussed on primer coats, a trigger gun with a fan head would be optimal. Maybe the Iwata Kustom Hi-Line HP-TH? Not cheap though...We've not used it either so cant't vouch for it. Would love to test it and make a video.

[@corntorteeya86]

What was that little squeeze air shooter thing?

[@scalewarmachines]

It's an air blower for photography - just to to blow away dust (as the airbrush had paint in it) - it's a useful thing to have hanging around. Especially, if you have a respirator on and you can't blow air onto your model from your mouth!

[@corntorteeya86]

Awesome. Thanks!

[@grahamharting2005]

like always great video

[@hugoquinn7432]

why do you use a laquar thinner. do you use an acrylic thinner for acrylic enamel for enamel and what is the laquar thinner for

[@scalewarmachines]

With acrylics, especially Tamiya, you have a choice. Ordinary acrylic thinners or lacquer. Sometimes we go with lacquer. It produces a tougher, more glossy coat than with their X20A thinners.

[@airborne2767]

Meanwhile my air brush cost 20 dollars

[@PixelGod240]

Meanwhile the work shows........ J/k kinda

[@theanimaster]

How does a trigger gun work? Can you blow just air through - is it dual action somehow?

[@scalewarmachines]

Yes it's dual action but simple uses a pistol-style trigger to pull the needle back rather than a top trigger. Otherwise the principles and airflow are exactly the same. Same tool, different firing mechanism!
