well sounds to me like your paint is too thick so the air is not sucking it up.

Did it ever work? If you've used it for a while it may need a good clean.

Are you using gravity feed - from a cup, or siphon/ bottom feed? Sometimes with siphon feed there is insufficient air flow pressure to draw the paint up. Try a different air source at higher pressure, or switch to gravity feed which works at lower pressure. Check the connections on the siphon, or cup if gravity feed. They may be loose, or have a blockage.
Which air brush are you using, with what air source - this information will help us give you a more detailed answer.

Using gas cannisters is an expensive way of spraying :x
Much better investing in a compressor :wink: You can pick up decent ones for about £70, which sounds a lot, but its one payment as opposed to endless payments for the cannisters :wink:

I would recommend getting the <a href="http://www.machinemart.co.uk/product.asp?p=000110300">`Wiz` Mini Air Compressor</a> for £64.57 and <a href="http://www.machinemart.co.uk/product.asp?p=000120550">Mini Filter</a> for £11.74 which removes water condensation. You will need a <a href="http://www.machinemart.co.uk/product.asp?p=000226560">1/4 inch nipple</a> for £0.93 to attach the air hose to the filter. You will also need an adaptor from the air compressor to the filter.

In that case it is a siphon feed. There is probably a jar or cup with a screw cap, inside this goes a length of plastic hose - make sure this hose is firmly inserted into the top of the cap. If it is loose the airbrush will draw up air and not paint.

Secondly there may not be enough air pressure to draw the paint up. You could try thinning the paint 50/50 with thinners to make it less viscous, and/or try a new air canister which will have higher pressure.

You can buy the air canisters from model shops, DIY centres, craft shops, the price will vary according to the size but are probably between 6-8 pounds.

Lastly make sure the airbrush and all the connections, hoses, nozzles are clean. Your instructions should tell you how to do this - follow them because it is easy to damage some parts.
Hope this helps.

I have been very kindly been given a Revell 'Standard Class' Airbrush by a family friend. As you can see in the picture, it has the brush, paint canister, aerosol canister adapter and the paint canister adapter.

Image

It however, needs a hose and either suitable air cans OR a compressor. I can probably get the hose from my LMS, but I was wondering what compressors would be good, as the prices of the air cans sound pretty cheap.

If I am to buy a compressor, I don't want to spend a small fortune on one. I would like to spend no more than £40, but from reading some threads, many decent compressors cost double this and above. I don't want to break the bank on this compressor, spending as little as possible - but I want to get something that will last, but not cost too much, and something that doesn't have any fancy gizmo's or controls - just the basic.

Cheers,
Owen

You will need £60.00-100.00 for a reasonable compressor. B&Q had a nifty little jobbie in the other week for £66.00 and I will be going back to grab one (if there are any left, oh pain of waiting for pay day!). Alternatively try Machine Mart - I think this one is Steven Pietrobon's favourite.

Don't be tempted by canned air, it simply isn't worth it.

peebeep

Seeing as £60 is still quite a lot for a boy who just gave up his job(yipes!), are there any half decent compressors for less than that, as I only want the compressor to do what the air cans do - just give me enough air to paint the model - nothing else.

Another alternative is use a car tyre. You will need an adaptor though. This will keep you going until you can save up for an air compressor. You can get an adaptor for Badger airbrushes (£4.90 from Hannants). I don't know if this will fit a Revell airbrush.

The Revell airbrush you have is also good only for brushing large areas. Here is my standard blurb on airbrushes and compressors.

I would recommend the <a href="http://www.machinemart.co.uk/product.asp?p=000510030">Pro Air Brush Kit</a> for £28.14 from Machine Mart and not the cheap Revell or Humbrol air brushes. I would also recommend getting the <a href="http://www.machinemart.co.uk/product.asp?p=000110300">`Wiz` Mini Air Compressor</a> for £64.57 and <a href="http://www.machinemart.co.uk/product.asp?p=000120550">Mini Filter</a> for £11.74 which removes water condensation. You will need a <a href="http://www.machinemart.co.uk/product.asp?p=000226560">1/4 inch nipple</a> for £0.93 to attach the air hose to the filter. You will also need an adaptor from the air compressor to the filter.

Owen, the extra you may have to pay for the compressor will soon be eaten up by the cannisters :evil:
Saving up for the compressor will be worth it in the end :D A single investment rather than the drip drip of continually having to pay for the tinned stuff :wink:

Get a compressor, you will not regret it!

In the last 2 months I have spent about £25 on propellant cans

Over a year thats well over £100.


Hopefully I should get my compressor tommorow.

Hi,
You might find what you want on the ebay. If you look at paints/accessories there is Revell one there at £40. It just might be what you are looking for.
Personally though I would go for the Machine Mart one that Steven recommends. £64 is very good for an instrument that will give many years of service. You could soon spend that amount on air canisters.
Best wishes, Ron.

I already have, but I just get confused by the numbers of bars they have, output, input, shakeitallaboutput and all the voltage, and the mini and full sized compressors! Anyone got a dictionary??
