Iwata HP-B Help!!!!

I recently got an Iwata HP-B, but haven’t had a chance to use it until now. There is nothing in the instructions that tells you how ot get the fine spray patterns. Are there any adjustments to make, and where do you make them, or is the pattern controlled simply by air pressure, how close you are to the work, and how hard and far you pull back on the finger tip button?

Stephen,
i know nothing abt the Iwata airbrushes, but one thing is the same no matter what you are using:
Practice!

get a sheet of cardboard, or some newspaper, get some paint in the cup and start experimenting w/ air pressure, trigger technique, distance, the whole ball of wax.

there may be some folks here who can give you some good info for that make & model, but you will still discover it isn’t exactly right for you. maybe it is hotter or colder, more or less humid, you move the brush faster or slower, whatever.

i wish i could give you better help for the HP-B, but definitely start spraying paper!

good luck,
ed.

no matter what brush you want to spray thin you paints a little more than normal and lower the pressure no higher than 15 psi and as far down as 7-8 psi. Then get close. Take off the needle guard if necessary. Also, be careful to use very little paint flow. Hope your hands shake less than mine.

The only control is how far you pull back on the trigger and how close you are.

I hate to break the news to you but the Iwata HP-B is NOT a modelling airbrush. It was designed for illustration work with very thin acrylic, water color, ink/dye, and gouache paints. It is not suitable for enamels, or lacquers as the tip and needle are very small being in the .16-.20mm catagory. [:(]

MikeV, I sent you an email with the question of what you think is a better airbrush for models than the HP-B. I want something for fine detail work. I have an Aztec that I use and am happy with for general purpose work.

Thanks to all who answered.

Stephen

Define, “Fine detail work?”

Mike

Being able to airbrush very fine lines, like used with German camoflage swirl patterns, or pre and post shading panel lines. One that will go down to about a 1/16 of an inch, or at leat an 1/8?

Any of the airbrushes I told you about in that email will spray that.
