You did a re-size on the model? Believe it or not, not everything scales up or down the way you would expect. It wold be nice if you started a build thread and posted pictures of what you have made (in a separate thread) of your models. I would encourage anyone building this to start their own build thread and post pictures,. That would be the best way to thank Mr. Rose.
To print A3 sizes on an A4 printer, I "re-sized" the parts in the following manner:-
I have a virtual printer (free download) called "Bulzip pdf" installed.
I opened the parts pdf with adobe and printed each page separately to the Bullzip printer, setting the paper size at A3 and no scaling and saving it in pdf format.
After doing all 27 pages, I then opened each "full size" pdf page in Paintshop pro (set to 600 dpi), and then saved them as a pspimage files.
I then created a blank image at 600 dpi and A4 dimensions.
Now starting with page 1, I copied the parts to blank A4 sheet images, re-arranging the parts as necessary.
Some parts were small enough to fit several on a page but others required splitting over 2 pages. They were split at panel lines so that it would not be obvious when joined.
The wing box sections which required 2 sheets each, I drew a line across them as a registration mark for joining.
One thing I have found with the fuselage bulkheads is that because of the large size, the tabs were too wide and caused "flats" on the fuselage sections. I remade the fuselage, dividing each single tab into 3 and this cured the problem. As you near the front of the fuselage, you can divide the tabs by 2. This was also done with engine nacelles.
I had slight lining up problems with the fuselage "red stripes" but overcame this by gluing the panels from the top registration mark, around to the red stripes and then cutting the panel along the top of the stripe, lining it up to the adjacent section and then continue gluing.
The problem that I had with part 8 on the reduced scale model did not happen with this large scale one.
I am unable to create a build diary as I can only spend 5 minutes at a time building as I am a caregiver and am writing this at 23:15 at night.
