Complicated paint masks
« on: September 13, 2019, 01:56:12 PM »
First, they are not stencils!  Stencils are different and made to be used again and crude compared to what we are trying to do.
I built a Rare Bear but for gravitational reasons I never flew it.  It was too heavy, so heavy the electricity needed to fly it would require its own nuclear power plant.  Don't ask, I won't tell you anyway.

The logo, nose art, required multiple paint masks.  Yes, I could have made a decal but it wouldn't have shown well against the deep purple background.  Besides, I like trying things I haven't done before.  The first step was to paint the background white.  The steps are labeled but I didn't take pictures of the final mask to expose the white outline.  It should be self explanatory, the little red diamonds are to line up the overlaying masks and are easily removed.  The rest of the trim was complicated also but not as bad as you'd think.  I drew it all on Corel and placed it over the digital drawing of the model.

I have some more info. and will try to find it.

Here are the .PDFs used to cut the masks.  It should explain the use of the diamond register marks.  The "RARE" and "BEAR" two different colors.  Its only a matter of covering up what you don't want to paint and cover what you have painted to paint the next color.  Easier than you might think.  The hardest part is coming up with the design and putting into a format to be cut.  Like I said, I use Corel but most any vector based application will work.  I did Howard's Impact for the World Champs, he had drawn it on a CAD program, saved it to a .DXF with which I was able to use.

This is the .PDF to show the working sketch.  It was done in Corel and can be manipulated to suit.  The final mask looks a little different, but this is where I started.

Here's another one from a couple of years ago.  Actually less complicated and with a bunch of decals.

It's about time someone besides myself called out the use of the word "stencils" when referring to "paint masks."

Funniest thing are those graphics companies that offer "stencils" when they are actually offering "paint masks."

Mike,

Your efforts are worthy of a standing ovation. Many kudos.

y'know Charles, in spite of our differences I appreciate your work.  You still need to fly your airplanes to gain some credibility for your hard work.  Vinyl cutters have come down in price and up in quality over the past few years, I'm surprised more people aren't trying more complicated designs.  As far as I know, most of the cutter/plotters come with design software.  What came with mine was limited unless you upgrade.  I find that even the "Student" version Corel is superior and does everything I need.  Yes, they are PAINT MASKS.

the new cricut maker is pretty slick, with a minimum learning curve.  it's worked well for everything i've throw at it so far.

and i've discovered you can import DXF's in to it now...   hehehehehhee

US Cutters are popular around here.  Mine is a Vinyl Express I bought from Sign Warehouse in 2011.  Somewhere in two hundreds will get you started.  I looked at Cricut, they are very limited.  My cutter is only 14 inches wide.    I've never had a need for a larger one.   

MacTac is the BEST masking vinyl for our purposes, no arguments.  I've tried others.  Transfer tape varies also. I get mine from Ordway, a distributor in California.  Their prices are best.

Think youll be suprised how well heavy planes can go IN THE WIND . Though you need heavy weight wire lines .
Flew the 5 Ton Strega this weekend , .018 solids improved it over the antigue 20 years of use .018 laystrate . For some reason .

Controlled speed with the schneurle .46 on a 12 x 6 4/2 . Only problem it needs a few gallons of fuel for the schedule .

Helps if the pilots fit , on it , muscular & has good timing though .

Nice Plane . Pity if you relegate it to a hanger queen . Comeon , own up . Whadasit WEIGH  then ! ? .

Too heavy for .018 lines and the battery capacity.  It is not a hangar queen, it is dismantled and recycled.

I've gotten on good terms with the owner/operator of Pit Stop Graphics in Sterling Heights, Michigan.

I see what equipment he has and do not want to try to buy what I would need to compete with him.  He cuts masks at a fair price, which I could not beat on my own.

HI Mike, that looks amazing. Someday there should be a for fun class called, "The Plane I hate to fly." And everyone flies "that plane" at least once.
Question:
So you design the mask on the computer, or use an existing design I suppose. Then the machine cuts it out. What does it cut it out on? Is it like a masking tape paper? Then you "stick" it on the surface and do your spraying of the color. Then the mask peels off? --and doesn't peel up your existing paint.

David,

If you take a look over at CFC Graphics vendor's corner, there should be information on working with masks and applying vinyl graphics? 

I do know I have Threads about this topic scattered around the Paint and Finishing Threads. Here's a link to CFC Graphics.

David, I design the graphics on my computer after drawing the airframe complete in two dimensions.  Once the dimensions of the model airplane is drawn I can make the trim scheme look pretty much like it will when it is applied.

I use Corel.

Our airplanes are three dimensional so sometimes it takes more that one try to get the design to wrap around a surface that is not flat, most are not!  If I'm copying a real airplane, like Chip Maroney's Super Chipmunk, I paste the .jpg image onto the workspace in Corel and copy away.  Our models don't look anything like the real thing in most cases some artistic license is granted.

Mac Tac is the preferred masking material in the Northwest.  It is vinyl and paint will not stick to it.  I buy it from Ordway, a dealer in L. A. and the will cut it to any width.  My cutter is only 14 inches wide but is plenty big to do any design I've wanted to do, including Paul's original Predator, although I didn't to the artwork only converted it to something I could use and cut the mask.

Yes, you sick it on the surface and paint away.  Not quite that easy!  The mask material has a backing paper that removes easily.  Transfer tape is applied to mask and the backing is removed revealing the sticky side of the Mac Tac.  On the more complicated designs I prefer to use Windex on the surface so I can move the mask around to where I want it.  There are a lot of tricks to getting things lined up, registers cut into the mask is one of them.  Like the Rare Bear nose art.

Going around compound surfaces can present a problem also. A little heat and a lot of patience helps.

Lanny used one of my masks for his airplane.  He only wanted a name and AMA number, pretty easy.

As far a plane I hate to fly, I still have one, sort of.  The Bearcat was just plain to heavy.  I didn't fly it so I couldn't hate it ;D  The Freedom 45 I had at VSC last March fills the bill, although I don't really hate it.  It is just very difficult to fly.  There is very little margin for error and in any turbulence it becomes a real handful.

I posted the top view .PDF once already so I won't show it again.  Here is the side view and cartoon characters.  It should give an idea of what I'm doing.  The cartoon characters are decals in this case and also came from my computer, very easy.

I wish I had a way to convert Corel files to .JPG, I don't so .PDF is the best I can do.

Thanks Mike. I'm going to try cutting some masks by hand for now and see what happens. I'm doing my first paint job with any sort of details. I originally bought decal stickers, but I knowthe army aircorp markings will look better in paint.  Same with the u.s. army lettering.  Well, at least that's my plan.

Hi Mike. Just tried my first mask, hand cut, and first time spraying color on my Black tiger. So far so good.
