Getting frustrated....questions

[Joe T]

So playing with one of my eclipse.35 and if I keep a decent distance from the paper I get pretty awesome lines. When I get closer to the paper my lines are like skipping and I can’t seem to get a decent thin line. Not sure why I decided to try this but I think it was watching MrMicron on his videos of the skull and he seemed so close to the paper and getting great lines.

Now, I guess I should try it with my .2 HPB+ and maybe that’s the ticket. Again, he seemed so close to the paper and wasn’t really getting razor lines but very nice smooth lines. Not sure what the whole line skipping thing is about. It’s almost like the paint wasn’t thin enough but further from the paper it wasn’t an issue. Is it because my tip was so close to the paper that the air was bouncing back off the paper and hitting my paint on the way back? I tried at different psi settings and no changes. Any advice for a newbie would be great

Thanks all

Joe

Getting bubbles in the paint cup?

 

[Robbyrockett2]

Sounds like your nozzle and or hold down ring aren't tight or sealed.
Check for any little bits of crud on the nozzle and the nozzle post.

 

[Joe T]

No bubbles. I thought I sealed it with chapstick but may re do it

 

[Robbyrockett2]

Loose air cap can do it too.
Otherwise id say its just tip dry or the paint is too thick.
A tiny ring of dried paint can be right where the nozzle and needle meet and hide. So it looks like no tip dry but it is.
That's all my suggestions

I think when I put th air cap back on. I only used finger tight, I guess I could use the little wrench and see if that helps

 

[Robbyrockett2]

Well, almost. Inside of the nozzle can crud up too. Which I push out by using the needle applying a slight amount of pressure toward the side and sliding it in and out if the nozzle with cleaner.

Finger tight should be fine.

There's a few line skipping threads. You might find some more info in one of them

 

[Joe T]

I guess I could take the same paint mixture and try it in my B+. That will have to wait for my long weekend which starts tomorrow after work.

apart from thinning your paint a bit more and using a lower pressure, you may want to check to see if you have the slightest of bend in the needle tip. I have had this problem before, the closer you get it is like the line gets wider or sprays to the side but you can't see any problem with the needle until you use a magnifying glass or use the coins trick remove the slight burr.
Just a thought

Try it with very reduced paint, if it still skips it’s the airbrush many good suggestions here to try, the Eclispe can do insane detail, not that I can get that with it!!

If I had to guess and apply my own experience here it’s possibly the reduction not being quite right for the application and causing tip dry almost immediately. I have only recently started to get good flow consistently, in the very beginnings I pretty much did more harm than good to my brush by cleaning the hell out of it trying to find some dirt as a culprit, when really it was a combination of poor trigger control and not having the right reduction / pressure.
In the video Mr.Micron was using a Micron, which allows thin paint run at very low pressure and he has excellent trigger control. The Eclipse can produce pretty fine lines but even the pros say that it’s not easy. Craig Fraser for example will often paint the wider areas with an Eclipse, then switch to a Micron for the tighter lines. I’ve often seen him do tight lines with an Eclipse, but then Craig is a legend for a reason! LOL.
This post isn’t mean to be having a dig and saying “it’s you Newb”! I’m a Newb too, and this is basically an account of my mistakes.
Of course it still could be some junk in the nozzle LOL, that’s the fun of airbrushing.

I have to ask since you don't mention it, but what paint are you usuming and what reduction and pressure? As mentioned, when working up close you should lower your pressure and thin your paint a little more, another question is do you strain your paint? If not I would advise that, some colours separate very quickly in the cup especially when they have been thinned, so it pays to get into the habit of a short back flush now and again to keep them mixed.

You're HP-B+ is an absolute darling of a tool and you would find it to be more forgiving for up close work as long as you're mix is right for it, it has the ability to perform better at lower pressure than you're eclipses, if you dont have an external MAC valve get one, it will allow you to drop your pressure at the brush rather than having to change it at the compressor.

Since you're eclipse is delivering a higher volume of air/paint than smaller nozzles the "bounce back" you mention could well be part of you're problem if your pressure is too high for the distance you're at.

Pics would help so we can see whats happening to the paint on the paper, also what paint , the reduction and how much air pressure

Wicked detail 1 drop paint 3 drops 4012. 25 psi. Also tried same mixture at 10 psi. I’ll try again tonight after giving it a good cleaning.

Hopefully if I have time tonight I’ll try the B plus and see if anything is different. I’m also looking for a Mac valve. Think I’m gonna get the grex from amazon. I however have a manifold with a regulator right next to me. Something I just thought of too after reading your post. My regulator seems to have been making a weird sound..hmmm, could also be the culprit.

 

[Joe T]

And, I am for sure not discounting trigger control. Lol

What's the reduction and psi?
Nm its up there already
