Gravity Feed vs. Siphon Feed

[StephenDeli]

I hate to keep bugging everyone with airbrush questions. But I was doing some hard thinking. Everyone was reccommending to me the Iwata Revolution CR(gravity). But wouldnt the BCR(siphon) be better because you can change color cups faster and wouldnt the cups be easier to mix than the built in cup thingy on the CR? What makes the Cr better? Maybe im missing something about gravity being better than siphon feed? I need help...

I personally prefer siphon becose you can change color very fast, and you can switch to thinner to clean your airbrus right away.

If you are not sure, Badger make a hybrid airbrus. It's Badger 360 I think, Siphon and gravity.. quite nice airbrush

I use the bottom-fed badger crescendo and it performes well and is easy to clean. The thing i don't like about bottom-fed airbrushes is that you can't use small amounts of paint as compared to a gravity airbrush.
With that said I would recommend the combination brush Vric mentioned. I don't know how well it performs but search for reviews.

thats the same airbrush as i have. mine has a problem...the paint doesnt come out in a constant stream....it pulses and its giving my paint a rough texture. i clean it every time i use it.....could it be i not cleaning it right? is there another thing that could make that happen?

I have a Badger Anthem and it come with a metal color cup, about 7ml can enter in it (by the spec) but I put about 4ml in it each time.. This is what I call small amounts of paint.

Might sound dumb, but are you thinning you paint enough ?

also there is a tutorial in flash that explain how to clean a crescendo

Hey Vric, have you had any problems with your crescendo? At this point I also am thinking of getting that because of the fact the set comes with all them jars and stuff...

For big jobs, siphon. For real detail work, gravity.

[StephenDeli]

Big jobs as in model bodies, small jobs as in spraying small objects?

I recently got the crescendo 175 set from Dixie art and I wont be changing it anytime soon. It has the small colour cup that is great for doing small parts and when u need only a smal amount of paint.

I know some people find it a hassle to change needles but with this set u get 3 different needles and they can be changed by hand very easily.

For $70 for a double action airbrush with everything you need I highly recommend it. Its also very easy to get used to. Not sure what weaponCIVIC problem with his brush is I certainly have had that problem.

I paid a total of 90EURO for mine to be delivered to Ireland and there is no way I could have got it cheaper.

If you are getting a pulsing spray the teflon needle bearing seal inside the body of the airbrush that the needle passes through is wore out. Badger will replace it free if you send the airbrush to them. The Crescendo is a great airbrush by the way.

I don't have a crescendo, I have an Anthem. Basicly the same airbrush, but Anthem have one Nozzle/Needle that do the same work as the crescendo 3 nozzle/Needle. SO no need to change any part to do small work. As Dublinguy say, the color cup is perfect for small work.
I don't have any problem with it yet (I clean it very carefully at every use)

[StephenDeli]

So is the Iwata CR worth it? Im starting to thnk that the color cup system is easier to change color with.

[jswillmon]

i have a cr and i love it. when i finish using a color i simply fill the cup, spray thinner through it and if i need i will wipe out the cup and spray a little more thinner. Then i'm ready for the next color. takes a total of a minute and a half at the most to change colors.

[StephenDeli]

^So do you mix colors in separate cups or in the airbrush?
