But that's good news though ! I usually give mine a little twist once I push them in. Push and twist,not forced but firm. I've also used a little light film of bees wax on the pipe in the past, more so it won't get stuck on there but it also helps seal the connection.. This had been more on my Badger 200 but the same would work for the Paasche. I've used bees wax on the threads of the needle too. For the longest time I used my H with the nozzle set a little back from seated and locked the set screw down there but lately I push it all the way in. I've found it's more how many turns out from seated to spray at than anything. As I mentioned there is a honey zone for this and screwed all the way out isn't in the equation any more than all the way seated is.. Anyway, glad to hear it's working !

The body is just air and air alone, no fluid ever goes through it. I mentioned system loss of pressure in an earlier post actually. Look to see how much drop you have in pressure flowing vs static. It could be dropping below an acceptable level to pick up paint. Your air valve could be flammed up and not letting enough pressure by out to the tip but this really a stretch of imagination. One thing about the H is it likes it's air for sure, especially with the larger needles. You've tried a couple of bottles and cups, I think we can rule out the paint holding device and delivery tube. So we are down to the nozzle assembly for fluid or air system for proper air flow. Other than that get the nozzle tip down into the main air stream, from the photo you supplied it's too high, too far out into the stream. You want that tip to be about center column of air or even a tad low from center for good suction. Right now your air is crashing into the side of the nozzle vs running over the tip where it creates the most draw.

When I think back on my own H screwing up and not spraying, it was too low a pressure for viscosity of paint each time of which that's been maybe twice in ten years.. I think twice I did that spraying artist paints, had to thin more then boost the pressure a bit. I mean that's all there is to this device, air pressure, fluid viscosity, no blockages. It should spray. There is also the factor of nozzle position. For max flow there is a point of diminishing return or honey zone if you prefer. If the nozzle is screwed too far out you actually lose paint flow rather than gain.. There is a defined range there of good flow equal to about three full turns of the nozzle and that's about it.
-
It's true that by the photo the needle tip is way too far up in the air stream. I just assumed though that different positions are known and tried. He doesn't seem new to the H or inexperienced. Still, something is causing this and I still contend that it must be simple. As to paint viscosity ( referring to Bobs post), the fact that it wouldn't even spray water was brought out early on in the thread. Finally though, It would be great to hear this has been and how it was resolved I must say.
-
I'd change out the whole tip assembly and maybe put on the metal side cup ( which is what I use 90% of the time anyway) and try again. Sort the other parts from there if it sprays this way..
-
Have you taken the tip/needle nozzle assembly off and unscrewed the nozzle from the needle and checked all those passages.You keep talking about the body and bottles but I've heard no mention of this thus far. IE take the needle assembly off the body, you have to loosen the set screw on the bottom to get it out. The body is fine, no paint goes through the body and you're getting air. It's a simple device it's got to be a very simple answer as well. 9 out of 10 times these issues come down to cleaning.

Question about Dupli-Color
Dave G. replied to El Roberto's topic in Model Building Questions and Answers
My experience with Duplicolor is it could use a slower thinner in it so blushes extra easy. But I'm not a fan of hot lacquers anyway so pretty much never use the stuff, or at least rarely. -
Plain hardware store lacquer thinner has always worked for me, since I've been using it to clean airbrushes for more than 50 years without a fail.
-
One thing I thought of is it's blowing air but is the air flow sufficient ? No leaks or blockages on the air side of things, including the hose and regulator ? Boost your pressure to 35 psi and see if it sucks any fluid up then. Also be sure your feed line isn't cracked and is sealed tight, good fit etc. Be sure the very tip of the nozzle is clear and clean.
-
IDK.

I don't clear coat enamel paint jobs, it's one reason I've used the enamel to begin with.. The models I use enamel on are usually old classic cars that never saw clear coat in real life. Done right it has a beauty all it's own so I opt to not ruin that.
-
I use 1000 in the bottle, thin it and airbrush it and it's smooth. But I get the Mr "Primer" Surfacer 1000 in white, can't speak for Mr Surfacer 1000 in black. What might be of interest to you though Mike ( and more why I writing this), the stuff stinks enough to blow your head off. But doesn't stink for long as it dries quickly.

Simulated Metal Paint
Dave G. replied to TransAmMike's topic in Model Building Questions and Answers
My Hobby Lobby locally has been getting a bit better stocked with paint lately, I could get by with them if need be in terms of paint. But I have a local hobby store too and online. Some things come from Amazon prime. As you know Mike, I have no issue with Testors enamels or other enamels even if decanted. Craft paint is fine, I'm sure I can get along with Createx and Wicked as I do with Liquitex Soft Body paints ( similar) or Goldens High Flow. I've been tempted to try the Vallejo Metal line of paints myself which HL stocks here. Hobby Town when we had those around here were no great shakes on paints IMO but that was decades ago. Anyway,all that said, I think your choices are Vallejo for acrylic metal colors or AK for solvents if you don't want Alclad. But Vallejo has a couple of different lines of metals, the metallics in MC or the bigger/wider bottles of metals. -
Thanks Skip. Ya I been airbrushing since the mid 1970's and painted in 1/1 professionally for 35 years. I think it's just this brush, if I pull the nose off and flush it that way all is well. For whatever reason back flushing with this one doesn't want to get it all. As it turns out a good stream of hot water in there with the nose off and needle out pretty well does it with Createx if it hasn't dried. And on the pedal needle protector some had dried and acetone took it right off. Additionally I usually use single action on models but was doing graphics so grabbed my only double action with .3. It shot the stuff fine was taking forever to back flush, it's nothing to unscrew the whole nose assembly so will do that going forward. Thanks for your detailed reply, normally I do pretty much the same as you.

I put it on wet with a Paasche H and #3 tip @ 25-35 psi. Generally one good wet coat and done. Try moving in closer and slow down your passes. If I happen to get some fuzzies it's easy enough to scuff off with 1500-2500 micro. I've also thinned it with lacquer thinner, we can talk about that another time.
-
The only black primer I use is Stynylrez so I guess I can't help on a second choice there. The key for me with that stuff is mix it with a badger power mixer. Works great under Tamiya X-1 which is also what paint I personally would use if I wanted to do a black finish in acrylic ( and have).. Can't speak for the Createx, I haven't shot Createx over primer yet just paper and cloth straight from the bottle @ 40 psi.
-
I'm thinking it's more the airbrush and dense pigment load of the Createx opaque paints. If I used my Paasche H I probably wouldn't have an issue.
-
I have a feeling I need to pull the tip assembly on this airbrush with this paint, the pigments seem never ending just trying to flush and back flush. That gun has always been a bit fussy to clean but it's my only double action. I don't normally use double action and won't on models but I wasn't painting models today but lettering. I like this paint though, I might mess with it some more.
-
Ok thanks Jon.

So are you guys who use Createx cleaning up your airbrushes after using Createx with anything but their own rather expensive cleaner ? My usual treatment with every other acrylic paint still leaves quite a bit of paint to deep clean it seems. I can usually flush acrylics to the point where deep cleaning isn't needed after every use, same for solvents. Not so much with this stuff. It's very easy to use though otherwise. Acetone did fairly well. I'm out of Windex so didn't try that. Fantastik just made it sudsy lol. Alcohol wasn't sufficient without a tear down. Maybe it's just that airbrush, it can be fussy to clean but usually once I wipe the needle it's pretty good.

Airbrushing Duplicolor?
Dave G. replied to Duncan4114's topic in Model Building Questions and Answers
That 2x red should shoot awesome through an airbrush. I've shot it straight from the can and it turned out great but the can gives a hose job to where a single coat is about it on a model. That's all I'll say except through an airbrush it should come out as nice as the other of the 2x line.. I stick with MCW or Scale Finishes only when I want an exact match but usually close enough is good enough for me and enamels work best for me because I've been shooting them since 1960. Also add that acrylics with a clear coat work well too in some cases. I don't like MCW lacquer, tried and the thinner he uses is too fast in the auto paints for me. I'd rather thin it myself, ended up with tons of polishing but the color is correct. And it's already too thin to add retarder so that option is out the window. I won't buy it again anyway where he has the enamel line out now.. -
Airbrushing Duplicolor?
Dave G. replied to Duncan4114's topic in Model Building Questions and Answers
If you want to decant something Get Rustoleum 2x , thin it an extra 10% or a bit more with lacquer thinner. Use the Yost method with that, it's sprays like any other enamel, comes out great and you get 12oz for about 5-6 bucks right at your hardware store. Airbrushes great, done it many times. For Lacquer I'd go with Tamiya Lp lacquers in the little bottles thinned with Mr Leveling thinner. I shot this in black and it came out awesome. Look for a Barbados Rex video on you tube for using that product. He did about a 40 minute video on it if I remember right. -
Question about Cadillac model kits…..
Dave G. replied to Street Rod's topic in Model Building Questions and Answers
The original MPC 28 Lincoln kit that I built back in the mid 1970's is my only recall, I don't recall it being finicky, I can't speak of newer iterations though. I also don't recall working steering on that version. But that's a long time ago and it's not to say it didn't have it and I bypassed it. I built that right after building the Monogram Classic Duesenberg Dual Cowl, to which I had previously built several of the Monogram Classic kits and as mentioned more than once now in the thread here, are straight forward builds.. Both turned out very nice at any rate. I still have them stashed in a box wrapped in paper towels and last I looked at them they could use a bit of reconstruction at this point. I don't recall that iteration MPC 28 Lincoln having any quirks about it. And I have not built later ones nor the newly released Gangbusters 32 Chrysler. I seem to recall though the Monograms are a bit stronger building/handling, the plastic felt more stout from the MPC plastic but I'm really digging into these old memory banks on that lol. I remember my at the time and now past on relatively new wife being quite taken by both model results ( she loved those old classic cars as much as I do). -
Question about Cadillac model kits…..
Dave G. replied to Street Rod's topic in Model Building Questions and Answers
Yep, so I flipped the name Connoisseur, That was under AMT and MPC. The Monogram classic cars are listed just Classic. One of these days I'll land a good buy on the Monogram Classic 1930 Packard 4 door Speedster phaeton. Right now the 32 Chrysler in MPC is listed Gangbusters. -
Question about Cadillac model kits…..
Dave G. replied to Street Rod's topic in Model Building Questions and Answers
Yes and yes to Monogram in 1/24. The Classic series and later releases were Connoisseur Classic. I've enjoyed those many moons ago and wouldn't mind them again. In 1/25 you have MPC in the late 20's-30's era classic cars, most notably Lincoln being among those in a couple of iterations. Those in the latest release are the Gangbusters series, I believe there is a new release on a Caddy or maybe it is the 28 Lincoln ( oops just looked it up , 32 Chrysler is freshly released and in well stocked stores for sure and I believe the 28 Lincoln is still around). Both companies though are pretty straight forward building they build nice with no real tricks to over come but not much for working items. Your own detailing helps, attention to accurate paint etc. I can speak on Entex and Minicraft in 1/16. There are some nice old stock kits still out there, of those two there are a lot of parts in both brands but Minicraft likes to throw in a hurdle or two to jump in my experience anyway. You're looking at 200+ parts in some of the Entex kits though. Italeri I have not worked with, I'd listen to those who have. I've done some Minicraft Model A's and the door hinges are both a royal PITB to work with and inaccurate and they are right there out in the open on the doors. The instructions are vague as in use your imagination quite a bit, hope you're good with inaccurate pictures. They's a bit of a puzzle kind of thing to build but the engine and drive line look good, in scale etc..
