Spluttering Spray Gun

[soundman]

another piont that can be a problem with the "arnold" clones is where the front half of the head meets the back.
there is a threaded sleve that holds the two together. you tighten it with an alen key accessed thru the hole where the needle & its adjusting stuff comes out.
these also break sometimes when dropped.

the giveaway for this one is the pot seems to wobble but closer inspection shows the whole needle cap assemble is wobbling on the rest of the gun.

Darren.

Is it fixed yet? We are all waiting with bated breath.

Nah, haven't had much shed time this week and I'm off on a three day walk tomorrow. You'll have to hold your breath until next week :eek:

I wonder how many PSI is tied up in all that bated breath

[silentC]

I tried all those suggestions but no go. Is the thing a dog? It's like the gun isn't getting a consistent air flow. If I sweep from right to left, what I end up with are regularly spaced patches of finish and the panel looks like it's been hit by a paintball gun.

I've got another gun but it has the wrong connector and the thread size is different. I'll have to try and find a male connector with the correct thread and give it a try.

Might have to go back to the old CIG Easy Sprayer...

ARRGH
dont do that

get down to your local tool shop & grab a "Star S770" for a round $100.

they are a great gun and very reasonably priced.

just a thaught have you given the dog a full clean.

I have one of those cheap arnold i use for glue & it was spattering a while back, a full dismantle & clean sorted it.

Oh have you checked the screw in seat behind the air cap is sealing to the body.

I finally got around to checking this out. It turns out that the nut that the needle passes through where it comes out to the trigger was loose. I think this is the one was talking about but I thought he was talking about the brass nozzle at the front of the gun, so of course I never checked it. Is that the one you were talking about soundman? Would help if I knew what stuff was called

Anyway, I've tightened it up and it made a big improvement. It still varies a bit but it's useable now. One thing I noticed when I disconnected the gun, there was a fair bit of moisture inside the hose. Could this be causing a problem?

It will cause a problem with the finish, get a moisture trap fitted, the inline ones are not too expensive.

Yep!

Try pulling the gun apart and checking all the o-rings. Even look for small air leaks in the hose by putting the hose in the bucket and look for bubbles.
