Lakes, ponds or swimming pools. Basically anywhere wher you don't have strong currents. I'm lucky enough to live by many such lakes.

That is really nice work Unkempt. What did you use as reference when building that thing?

... OK, three mistakes. I didn't have anything that looked right for the guns, and making a six bladed counter rotating prop seemed like too much effort considering I had a nice 5-bladed one right there, and besides, in the PC game the model actually has a 4-bladed prop. I actually meant that I forgot to weight the nose; it should be hanging horizontally. Shifting the support backwards would fix that, but I spent ages getting it 'right' in the first place so I'll just pretend it's some sort of 'action pose'.
References: mainly screenshots from the PC game, but I also found one of the old CS books on the net as a PDF which had some (not very good) plans in it.
And finally, if anyone likes Crimson Skies and hasn't read Research Indicates' 'Let's Play' thread they should do it because it got me dusting off my CD to replay the game as well as making this thing.


edit: yeah, that is a really nice boat.

Ever since i bought my airbrush, i've been using Vallejo acrylic paint exclusively. I guess i never really thought about it, but is there any reason why i can't buy and use the bigger (cheaper) bottles of non-name brand acrylic paint, as long as i thin it?
Paying $2.59 or so plus S&H (since my local hobby shop decided to go RC-only) for a tiny bottle of paint seems stupid, when i can get 8oz or 20oz bottles, whatever size they are, for $4 or $5, whatever they cost. Granted the selection isn't great, but i really enjoy mixing my own colors.


TL;DR
Any reason i can't use cheap paint in aibrush instead of more expensive stuff

Yes and no. They could work fine, but not all acrylics are created equal. Dedicated airbrush paints usually are made of much finer particles than regular hobby paints. They differ so they shoot and flow much easier through the airbrush and onto the surface. The obvious benefits are smoother layers, less texture, finer lines etc. So it kinda depends on what your goals and skills are.
And it depends on the gun you are shooting the paint with. since coarser paints are more likely to clog up the innards of the brush if not properly cleaned, I wouldn't use cheapo dolllarstore paints with any of my vintage brushes or one of those pricey Iwatas.

(Also Holbein paints are the poo poo and awesome)

(edit: There is no need to buy the most expensive paint, but there sure is a difference.)

Made some more progress on the chris craft. After days and days of sanding, I finally got the hull and deck stained, and layed down some fiberglass and resin on the deck.









Once the entire hull is glassed, it's days and days of more sanding in between coats of resin before varnishing.

I was thinking about getting an AH-64 Blackhawk. I recall seeing a USA website that looked to have fairly high quality models, and when you looked at the page for the model, there was a box on the right showing available accessories such as photo-etched brass detail pieces. My memory is pretty hazy, but I think the model kit was around $50 and the brass detail kit was another $30 or so. Does anybody know what online store this might have been?

I'm looking at getting an airbrush and am thinking that a CO2 cylinder would be the way to go for my needs. Can anyone explain exactly what parts I would need to go between the gun and the cylinder? Also, does anyone have any idea how long I could expect a small (5 lb?) cylinder to last when using it for airbrushing?

Hopefully you mean AH-64 Apache (the Blackhawk is UH-60). Sprue Brothers has something like you describe http://store.spruebrothers.com/148-hasegawa-ah-64d-longbow-apache-7223-p6148.aspx

I really like Sprue Bros, shipping is reasonable and lightning fast.

If you are a beginner I'd recommend not getting detail sets - the Hasegawa Apache is a very nice kit and will be plenty fiddly without tiny brass parts. I'm fairly advanced but killed my building output dead because I had to get all the detail/correction parts, so I have literally a closet full of partially built kits. AMS - Advanced Modeler's Syndrome and it's debilitating.

After about 18 months I slammed together a 1/72 scale Hobby Boss Ka-50 Black Shark and it was great.

Huge brainfart there. Yes, I meant the Apache. Thanks for the link! I believe that is the website I was thinking of. Looks like the detail kits are sold out anyway, so I guess that won't be a concern. Do you have any idea what that die cut paint mask is for?

Masking canopy frames - that's one aftermarket item I would absolutely recommend. They eliminate the need to trim tape around the canopy glass, which is my least favorite part of model aircraft building. Pull the pre-cut mask off the sheet, stick it on the canopy. Done.

If you really want the detail stuff, check out Squadron.com or Roll Models. They're good US mail order shops. Hannants in the UK is also very good and ship internationally.

Whats the recommended paint for high use plastic items? I'm looking to paint a few Xbox controllers and cases with my new airbrush, and I'd like to know what will stick. I'm going for either glossy or matte, but smooth and polished to be comfortable either way.

I've done one controller with sandpaper, tape, and Krylon Fusion, it came out nice, but orange peel and not enough control are the main issues from making me totally happy with it.

Multiple layers of color, sanding with 800 to get the details/wear, up to 1200 grit wet, then 3x clear coat and 2000 grit wet sanding.

Here are those results:

My airbrush arrived, and seeing as how it was an estate sale find, it is of course, filthy. How do I clean it so its right as rain? Dried paint in both cups, and possibly some in the airbrush itself. The web is full of different suggestions each with a different mix of chemicals.

Based on the paint contents that came with the set, it appears the PO was using acrylics.

So, while I work on my model car, how do I make the airbrush good as new?

Skunkduster
Jul 15, 2005




I use this stuff that will clean dried oils and can also do acrylics with a long soak.

http://www.dickblick.com/products/winsor-and-newton-brush-cleaner-and-restorer/

Take the airbrush apart and soak it all in a bowl full of that stuff for a day or two, then do some scrubbing with one of these kits:

http://www.dickblick.com/products/master-airbrush-cleaning-kit/

There might be a tiny rubber gasket in the air intake valve that you probably don't want to soak in any solvents. However, there shouldn't be any paint in the air intake valve anyway, so don't soak that. The needle, body, and head assembly should be the only things with paint on them.

You may be able to use Simple Green, Gasoline, Lighter fluid, or whatever poo poo you find under your kitchen sink instead of shelling out the money for that Dick Blick cleaning solvent to dissolve the paint. However, I would recommend getting that kit with the wire brushes.

Lacquer thinner will eat through about anything, and will probably be the way to go. Soak the parts in a jar of the thinner. Of course, just the parts that are exposed to paint, I have no doubt that it would wreck the air valve parts.

If you know the paints were acrylics, an ammonia based glass cleaner would also probably work, while being substantially less noxious.

I just did some maintenance on my Iwata HP-C, and I always forget how great it is once it's really clean. Pencil thin lines, it's really sweet.

I tried hot water and elbow grease and a bamboo skewer for the paint pot and now all is clean and a fine mist of water was sprayed across my bathroom mirror. Had to use a pair of pliers to get the needle out of the gun, it had glued itself with paint, but it slid right back in and all the paint is gone! Sprays great and the compressor is nice 'n quiet.

I can't wait to break out the paints tomorrow... :D

Welp, I'm having trouble with paint adhesion.

I've painted another xbox controller in the following manner:

400grit rough sand to help adhesion
2 coats adhesion promoter
2-3 coats acryl paint
masking tape layer
2-3 second color
cure
finish sand before clear coat
clear
sand/polish

When I go to smooth down the color coat with 1000 grit after 24-48hours the paint still comes right off, especially curves and corners, even with like super super feather light touch. I can go back and feather the color back in, but a once and done would be preferred.

I'm trying a longer cure with some heat in the back ledge of my car today, but I'm not holding out much hope.

Suggestions?

Should I just give up on acryl paint and go to the automotive side of paints, lacquers, enamels? Is it perhaps my technique that needs work?

I'm open to any and all suggestions.

Edit:
Attached are pictures of my work so far.
The red/black one was done with krylon fusion rattlecan and the blue one was my first airbrush project. I'll post pictures later this afternoon of the third controller and the wear marks.
