Camo masking

Postby Damo » Wed Apr 04, 2012 5:28 pm

Hi all...
I'm in the process of masking my Academy 1/72 Tempest, and have been playing around with different ways of getting the pattern right. I think I may have made a bit of a breakthrough, although I know there are tried and true methods that we all use already.
I've printed the paint guide at 1/72, and what I've found is that Tamiya tape is translucent enough that the pattern is easily visible, even through two layers. What I'm doing is laying the tape down over the areas I want to mask on the guide with the first layer going one way, and the second layer at 90 degrees to the first, then cutting the pattern out with scissors. Up to date, I've had issues with removing the tape from the paper when it's cut out....firstly, the lower layer tends to pick up the ink from the print, and secondly, it's very difficult to remove the lower layer unless there's some overlap. So now for the lightbulb moment...
For my next attempt, I'll lay down some clear packing tape first, then the two layers of Tamiya tape. This will prevent the ink from being picked up, and should facilitate easy removal of the mask.....stay tuned..

It works quite well, and only takes seconds.

DIY mask applied to model...Didn't quite cut it out right, but you get the idea. I also penciled in where the leading and trailing edges are to make alignment easier..

Thanks Alfred. I decide to go this route because I want the hard edge demarcation. Soft edges...well, haven't been down that road for a while, so we'll see what happens then. Freehand I really suck at!

As an addition to the above tip, I'm playing around with scratchbuilding a cockpit for a 1/72 Chipmunk. The intention is to build a tub that slots in from underneath the fuselage.....whether it ends up getting done remains to be seen. All that aside, I've been drawing some basic parts in CAD to get some templates to work with. Printing them out so's they're useful presented a small challenge - getting them on paper is one thing, but transferring that to the plastic is another. However, necessity being the mother of invention, I used a variation of the technique outlined above. First, I printed out the templates. Then placed a strip of the clear packing tape over the top. Then a strip of wide Tamiya-like tape. Then ran it through the printer again. Result: All my templates printed on tape - no issues with paper jam or anything like that - which can be stuck onto the plastic, and cut out.
Sometimes I'm so clever, it's scary! :lol:

Thanks for that Damo
One question though! How did you achieve / calculate 1/72 scale " I've printed the paint guide at 1/72 " to print paint guide?

I scanned the paint guide, then resized it in GIMP (free program similar to photoshop). It took a few goes to get the sizing right.
