Ansaldo SVA 5 1-48
I started building a model of my realization, the Ansaldo SVA 5,
but, beyond the difficulties of my design, remediable (!!), I decided to print the tables, with the laser printer on paper 160gr., in order to have a better simulation of the plywood. But, in paper folding, cracks are formed on the printed here is the model: What do you suggest? T.I.A. matt77 |

Dear Matt:
I liked the color and the texture, however in my old age I am becomming an advocate of Layering. I would like to see the foot holes with raised metal rim and the hole itself deeper. and the metal teardrops on the sides as another layer dished from the back and glued on. Thats my two cents worth, MILES |

The model looks great, but I didn't notice any cracks in your photos. The one thing that I did notice from looking at your parts layout, is that you didn't take into account the grain of the paper which normally runs in the same direction as the long side of the paper. When you try to roll parts, or score and bend parts across the grain you will find a tendency for the paper to crack at the score line, crinkle when trying to achieve a tight roll, or fight back when you're trying to achieve a gentle roll. Paper doesn't like to be stressed against the grain and the modeller pays a price for trying to bend it to his will (pun intended). For easier shaping, your fuselage segments should be rotated 90 degrees. I don't know how your wings were laid out on their parts page, but they should run along the length of the paper, not across the width. Picture a sheet of paper as if it were a mat made from drinking straws. Visualize rolling that mat longways - no problem, right? Now visualize trying to roll it the other way. Not so easy. If you wanted to score and fold that mat lengthwise, you'd get a nice smooth sharp edge. Now, think about scoring and folding across the straws - you'd have some mess. The same goes for a sheet of paper. If you're ever in doubt about which way the grain runs, try tearing a piece - it'll tear nice and straight with the grain, but it'll do what it wants when you tear against the grain.

thanks rockpaperscissor, thanks for the suggestion.
I had never thought of that! Here is the design with all the wings: matt77 |

wow! The wings are as beautiful as the fuselage. You're very talented. The wings are oriented properly in regards to the paper grain. On page 1, I'd reorient the fuselage sides, uppers, and especially the bottom piece 90 degrees - you want the grain to run lengthwise along that long thin tailpiece. I'd rotate the cockpit interior 90 degrees, and the kite shaped piece with the "5" on it 45 degrees to line up with the grain. On page 2 I'd rotate the 2 small pieces in the lower right corner 90 degres. I think these changes would make construction easier with less cracking. Your model is fantastic. Super job.

One more thing - if I'm not mistaken, laser pages have more of a tendency to crack than those printed with an ink jet. That may be a contributor, too.

I haven't rried this myself, but I think that others have coated the surface of the paper with a spray varnish to minimize cracking.
