resizing a pcb

[Deathwish]

complicated ?, have you ever visited the time nuts threads, now that is complicated.

Print it as a PDF with the correct scalling, upload the pdf. then everyone can just print to 100% scale. Why is something simple getting so complicated?

well, I have no printer, don't know the scale, and so I wait for anyone to suggest the scale compared to what I've uploaded. If the task is such a trifle, perhaps you can assist in a practical manner ?

  No idea if it's the right scale or not  Try it at your own risks.

Opened the PDF in Gimp and measured, then cropped page2 and changed the resolution after measuring the DIP leads spacing. Was 100 DPI now 210DPI, so YMMV on it.

Kind of liking this new GIMP version, even though it annoyingly only will save in certain file formats, to get the more common file types you have to export it. But it does the job well enough, still getting to know just how much it can do. Works for pretty much all image manipulation I do in any case.

I know what you mean ! I just don't understand why they have to come up with such silly ideas. I wish they'd take more note of the community and throw out the crazy person who secretly works for photoshop. I hope the whole export silliness disappears in the next version. And never detach a dock ! they never go back as far as i can see. (grumble) still, it beats everything commercial !

sean, your sizes are off, they show me 2.4 between dip pins not 2.54 , any chance you can re do it ?.

Try now.....

Changed to imperial and did it again slightly larger.

[Deathwish]

What did you do ??, its gone massive 

[Deathwish]

I appreciate the help, but I have to sleep a while, so bbl ok.

[SeanB]

Have a siesta and try this one.

you can find it here

http://dalincom.ru/datasheet/HAKKO_936_schematic.pdf

On page 5, you find components overlayed with the layout. Look up the size of the AC05D in the datasheet, then scale...

[Deathwish]

I think I am going to play with re doing it in eagle / cadence and outputting it to gerber copying the original pcb layout and design. could take a year or so though.

Are you sure you can't scale it on the printer?  I don't think I've ever unable to scale a printout on a printer's Properties settings.  There is practically always an output scaling option somewhere - example below.  The available step sizes (usually whole percentage points) may be too course in this case however.

[Deathwish]

I looked but I cant find it , its only a epson , I really want a HP laserjet 4 like I used to have for my pcb artwork. but right now I am still buying hardware etc.

PDF attached with the copper image which has been scaled so that the pins in the middle are 2.54mm pitch.  Imported into gimp at 1200dpi, exported to a PDF page. 

Print this PDF WITHOUT ANY SCALING (common mistake, PDF viewers often "fit to page" or similar by default, make sure you turn that setting off, I use Evince on my ubuntu machine).
