Ada Posted April 10, 2014 Share Posted April 10, 2014 Hi, Ok so I like the idea of trying out a airbrush, the good gear is pricy and I don't want to splash out yet before trying my hand at it on some old models. So, I've got a cheap airbrush, £10 with a couple of pots and a connecting pipe, and a canister of compressed air, dirt cheap I know and I'm not expecting too much. Connected everything up, I get some air flow, but there doesn't sound like a great amount of pressure and no sign of any paint coming through. As far as the set up goes I think it's all right, (how hard can it be) connect the pipes each end and off we go right? Checked flow through all individual parts by blowing into water, I get bubbles so I'm happy there are no blockages anywhere. So, issues are, low pressure, no paint flow. Could this just be down to my cheap as chips set up? Or, are there some pointers anyone can give me?

greendestiny Posted April 10, 2014 Share Posted April 10, 2014 Do you know anyone that has a compressor that you could hook up to even for a few minutes to test it on? It sounds like you have air flow issues. The compressed air canisters are bad for that. In the end if you like airbrushing you will spend less by getting a compressor. Unless you need it to be super quiet you can pick them up cheep at hardware stores.

madscuzzy Posted April 10, 2014 Share Posted April 10, 2014 Cans produce less pressure when they become cold, especially over use. Link to comment https://bolterandchainsword.com/topic/289343-airbrushing/#findComment-3648647 Share on other sites More sharing options...
Ada Posted April 10, 2014 Author Share Posted April 10, 2014 Cheers for the quick response fellas. After posting I went back to the setup and had a little play, and I've now experienced a little success!!!! It seems that I was a little over zealous in connecting the pipe to the compressed air can (wouldn't have thought it could be too tight???). However after slackening it off a tad the pressure noticeably increased from the nib of the brush, so I attached the paint pot again and I now have some airbrush action going on!!!! @greendestiny, no unfortunately I do not, which is a real shame right now. But it looks like you were right about airflow, and as I've found out it's not just the can which is a little ropy in my setup lol Quite pleased with my first attempts though. Any advice on thining paint guys? Currently I'm using water, which to all intents and purposes is working fine, but I'm keen to hear any advice.

GumbaFish Posted April 10, 2014 Share Posted April 10, 2014 I used water for a long time but ended up trying the Vallejo airbrush thinner some time ago and I personally find I have an easier time getting good coverage and just fewer problems in general. It is personal preference though, some people find different things easier to work. I find that more often than not a 1:1 ratio of paint to that thinner is what I use and serves as a good starting point for thinning.

AtlasDM Posted April 10, 2014 Share Posted April 10, 2014 I use a 4:1 solution of water and clear acrylic floor shine to thin my paints. I can't remember for the life of me what it's called now because they changed the label. It works really well for me.As for low pressure from canned air, try setting the can in a bowl of warm water to keep it from getting cold and losing pressure. Just don't let it sit for too long without spraying or the pressure inside can build up too much.

GumbaFish Posted April 11, 2014 Share Posted April 11, 2014 You probably use Future, or whatever its called now (I think they may have changed the name a few years ago or the names differ between countries or something) Link to comment https://bolterandchainsword.com/topic/289343-airbrushing/#findComment-3648979 Share on other sites More sharing options...
Hemal Posted April 11, 2014 Share Posted April 11, 2014 Beware that the current stuff is not nearly as good for models as the older formulation - I scored 2 bottles on fleabay just recently so be wary..

Ada Posted April 11, 2014 Author Share Posted April 11, 2014 Thanks for the feedback guys, I've just grabbed a bottle of Vallejo airbrush thinner off eBay, I'll give that a go. If I were to go and take the plunge and invest in some good quality equipment, what would be your advice?

Bung Posted April 11, 2014 Share Posted April 11, 2014 Get an Airbrush which will supported some years from the company with replacement parts. You will have to replace the needle and the noozle over time, which is cheaper than buying a new airbrush.

irwit Posted April 11, 2014 Share Posted April 11, 2014 honestly those cheap sets really are not worth it. Ebay a cheap second hand compressor and a chinese airbrush. You could get going without a huge investment. Those cans of air are expensive, useless and dont last very long so become even more expensive the more you use them.

Hemal Posted April 11, 2014 Share Posted April 11, 2014 Second buying the compressor, they don't cost too much - I bought a set with two brushes and a compressor for less than £100 and its fine Link to comment https://bolterandchainsword.com/topic/289343-airbrushing/#findComment-3649403 Share on other sites More sharing options...
Ada Posted April 15, 2014 Author Share Posted April 15, 2014 Yep, duly noted and I've purchased one. AS18-2 natty little piece of kit, came with an airbrush as well which feels like real good quality. Now I just need to practice some with it. Thanks for the feedback.
