You can do it on your scanner, but you have to mark out your drawings,

1, find the size of your paper A4 , which is 8 inches wide.

2 your doubling up the size of the scan .

3 to do the hull length , mark off every 4 inch. You only need to put a small mark.

4 set scanner to 200 per cent .

5 set the perferated lines on the scanner to either side of the marks and scan and save, then print them off and tape them to gether, if it is to large reduce by a few per cent, if to small increase.

thats how I do it for all my builds, ARH

the easiest way to me is to hit the road , going down to your town , go to a copy shop , they should have a plan copying machine , ask the guys & gals to supersize your plan , pay the bill , hit the road again back home ...

This is what I do , it costs almost nothing , about 2.5 � the square metre ( about a square yard )

It may be just as easy to scan at 1 to 1 and set your printer to print out 200% in the options panel.

No matter which way you go, the biggest challenge you will have is trying to print everything out on standard paper. You will have to scan in bits/sections at a time and the print out will be twice as large. You will have to play with the print preview to make sure you print out everything. That's why a photo manipulation program come in handy, to make the images fit onto a standard sheet of paper. It's also a real pain to fit it all together after, as the prints may not be even and you get lines that won't meet up.

I'd go the copy shop route, much simpler and it's doesn't cost that much.

But if you decide to go this way, you better have a lot of patience!

The tough part is printing, most programs these days try to inject some intelligence into the printed result by resizing it for you for best effect. I made a real annoying boo boo by failing to spot the X-Y ratio had been modified for me by Photoshop and produced a Frame section taller than it should have been, by the time I found out I had cut the blasted frames.

I would advise making sure you measure in the X and Y axis on a test print to make sure that is not happening to you.

To actually scale I scan at 1-1 then use the percent increase of image size, hence my Jecobin 1/96 to 1/72 is 133% I scanned the whole set in sections and pinned it all back together with photoshop, produces a really useful reference on the computer and I can print out sections instead of struggling with the large plans. It also means that despite my original plans getting a bit worn I can nip the scan on a CD to work and print out a fresh set on the CAD boys mega printer. Er, I mean take it to a professional print service and get them to print me a fresh set.

(I am presuming this comes under the bit about being allowed to copy your own product provided you do not intend to distribute it to anyone else or sell it)

Incidently: I was watching a program on building a scale model of a Globe Master the other day and they produced their wing frames by sending drawings of the frames to a laser cutting service who whipped the lot out on a laser CNC machine and posted the ply parts back. Neato! Of course they did not mention how much that service costs!

I do feel a bit green when I look at the beautifully interlocking frames coming with the Bismark part work kit and the rough and ready effort of my scroll saw perching drunkenly on my keels!

you can also use the poster printout software to print the plan sections on standard paper prepared for glue-it-together...

poster printing software?

middle watch have you seen the same program as the one making the globemaster but series one?? he made a hms fearless

Missed most of it worst luck, I assumed it was to do with catwalk models when I saw it on Sky planner, hope to see it repeated, on the Globe Master series they also mentioned they had done a Hercules, though it crashed, like to see that too.

I believe the Fearless actualy had operating landing craft, tank and helicopter?

The annoying thing about the series is the start, the wife invariably pokes her head round the kitchen door (got her trained at last!) and spots the guy in a dirty old mac sneaking into a porn cinema and demands "What the hell are you watching?!"

Yeah, I printed my 1/72 scale plans (magazine 1/200 scale scanned, processed, deeply redrawn, scaled....) of soviet destroyer escort Uragan using it. You feed it an image, it automatically cuts it in pieces and allows you to print a large piece on the standard paper (A4 or Letter, depending on the country). Im not sure which one I used in the end, I trialled a number of the programs.... Will check when ill be back from the office.
