Will you be able to cut coloured decal film rather than masks?

Yeah, Jens.....what's your thinking here?

Fanblades for a Boeing 777 in 1:144 scale...  The GE90 uses composite first stage compressor blades, but the leading edge of each blade is metal - presumably to improve impact resistance as composites don't like that sort of thing.  The shape of the blade is not just a simple straight edge, and I have been thinking how to represent an essentially black blade with a silver/aluminium leading edge that will be consistent in width between all blades.  One idea was cutting masks of course, but sometimes you don't see the effects properly until the masks are off.  The other idea was to cut silver trim film to the shape and apply along the leading edge.  A thin strip of decal film can deform more easily.  However, painting the blade silver and then applying a cut to shape black decal will allow for some repositioning and make gauging the width of the silver leading edge fairly easy.  The blade is fairly flat although it twists, so should not be impossible to cover with a decal by some chemical persuasion.

Below is a pic of my Trumpeter C-47 completed using masks you cut for me a couple of years ago.  This was the first model I had used masks on, Thanks to your very clear instructions, I was most happy with the results.  Just wanted to say Thanks for always coming through with my requests

Hi Jens,

Interesting, as decals come on a backing sheet then, in theory, I should be able to cut it. I don't know what will happen when/if I do cut it and the only way is to try it. If I have some single colour decal sheets I could give it a go but, as I don't use decals I may not have any left! O.o I will see if it can be done though and get back to you :) The problem may be the actual shape of the blades but, from what you are saying the actual shape isn't an issue, so I will need some idea of the size required; I'm guessing that you are thinking of wrapping them around the blade? Separate strips might be the way to go though?

G'Day Bruce (I do love saying that :))
Yes I remember this I hope that you had fun doing it? Your C-47 looks very good. I am in the process of building the Airfix 1/72 scale kit and I hope that it turns out as good as this :)

Thanks for your interest in solving my problems:)  I will first need to trace the shape of the fan blade and create a vector file.  My thinking is to just make a single side of each blade with a possibly reverse black decal.  They will then meet at the trailing edge which I believe will be invisible.  The shape is too complex to wrap around.  I do have some black decal film that I can send you for trials.

Yep back and front decals would be the way to go :) I haven't had chance to look to see if I have some single coloured decal sheets, I did have so I just need to find them, I'll have a look now and report back :)

Hi Jens,

I found an old, very old! O.o clear decal sheet and, with some trepidation, lowered my cut pressure to 15gms and did a test cut (the problem is cutting through the backing sheet and that will damage the cutting strip which is something that I have never done in 10 years :)) I gradually upped the pressure by 10, then by 5 gms, doing a test cut each time and when I gout to 50gms there was a very slight indent of the test cut pattern showing on the reverse side of the decal backing sheet. So I stopped there and the cut looked good, I just need to know if the decal film had actually been cut through. It is very much thinner than the normal vinyl masking material which is only 80 microns thick and I couldn't lift the cut decal piece off the decal paper, it had to be soaked in water, so that was the next step.

I can report that yes I can cut decal film :) In fact every cut was free of the main sheet.

So to move forward with this I would first of all need a a vector file? We can then talk about what would need to happen next? :)

Hi,

 

I am about to start modelling the Hasegawa 1/72 F-35A Lightning II, and I am already facing a problem. The kit has decals included for all the RAM panel lines, which really is quite nice. I have previously built the Italeri kit, and it took me 3 long nights to mask the panels, after having initially painted the model in the RAM colour. The problem with the Hasegawa decals is however that the RAM colour is too light. I was thinking about making a new set of decals and have thus scanned the decal sheet and traced the RAM decals in Adobe Illustrator. I then got the idea of possibly having the RAM panels cut as masks, and I would like to ask, is this something you could help me with. The artwork is a bit complicated, as can be seen in this image of the decal sheet: http://www.cybermodeler.com/hobby/kits/has/pages/has_01572_decals.shtml (somewhat enlarged), but I can provide ready made vector graphics.

Hi Nils,

If you have drawn the required graphics then I could, possibly, cut the masks for you. I say possibly because every time that I have been sent files I have had to adjust them to be able to cut them, those drawn to produce decals from are the worst! Basically the cutting software will see all lines,  so if you have drawn the shapes by overlapping rectangles then, when cut, all the separate rectangles will be cut. So each of the lines need to be a single entity, start to finish. The best thing is to send me the file so that I can take a look and, as this is something that I could definitely use I would do it for just the postage? But I do need to check it out first. Message me for my email address :)

Great. I will send a PM. I am aware of the issue with overlapping objects, and will check the artwork before sending it.

You should have something in return for the job, though. I can offer any Vingtor Decals sheet, that is if you still use decals...

Hi Nils,

Great stuff :)

If this turns out to be what I think it is it will be very desirable to other modellers and so it would be an ideal item to offer to the general modelling public, probably through Alex Glass at Uschi van der Rosten who I cut quite a number of masks for :) So, because of that, I certainly couldn't charge you for them. The only decals that I do use, and that is under duress, O.o are for the likes of stencil data! So thanks for the offer but I'm cool :) 

Now just having said the above it strikes me that you might want to offer these as masks? Or are you, as a decal manufacturer, loath to sell masks? :D

It is quite fine with me if I can concentrate on printing decals, if the masks will be available from other manufacturers. I am sure the masks will be of interest to other than Norwegian modellers.

I would have thought that anyone building the Hasegawa F-35 would be interested.  Looking at pics, it appears the RAM areas are also metallic in appearance, but a shade lighter than the fuselage, so the decals aren't correct.

Yes I would have thought so too, but I do like to ask, it fuels the expectation :)
