    How do I take the tif file from here: http://usuarios.arsystel.com/naviost/nst/I-planos.htm (its the first file) and get them to scale at 1/48?
    Any help would be greatly apperciated :)

    Thank you!

    You go to www.gimp.org and download the GIMP (GNU Image Manipulation Program) for free, and open the file with it. Then, from the command bar at the top, click on Image, and down towards the bottom of the popup menu that opens, click on 'Scale' then choose 'percentage', and type in the percentage of enlarging that you want. And then tell it to do it. DO IT NAO!

    Thank you! ok I am downloading now. the site says the current scale is 1/75 whats the percentage I need to type in? sorry my brain has decided it does not feel like remembering how to figure that out.

    Current scale is 1 / 75, desired scale is 1/144, consider x to be the value needed to transform from 1/75 to 1/144. Solve for x

    (1 / 75) * x = ( 1 / 144 )

    x = ( 1 / 144) / ( 1 / 75)

    x = ( 75 / 144 )

    Also it might be a good idea to draw a ruler in the image that you can measure once printed to check that it all scaled to plan.

    Wow, I don't know how I didn't notice that you said 1/48th as well. Sorry about that

    No worries the formula should still work :) This ship is going to be huge if I ever get her off the planning table and under construction. something like 4 ish feet long (not that long) and over 1 foot wide and the hull without masts will be over 1 foot tall from scale keel to deck. Not counting the extra keel I intend to add for stability reasons.

    I'm looking at the PDF plans of the GOLO. Most are listed as .015 / meter. I am getting all twisted trying to make this conversion.
    .015/m = 1.18"/39.37"
    Where do I go from there? (been 50+ years since I learned any fractions) Eventually I want 1/144.
    Any help?
    Thanks
    Barry

    In a hurry so no time to explain it, but increasing it by x2.16 should do it. I think.

    think you have to downsize by Tug's number..

    0.015 : 1 is a larger scale than 1 : 144, it is somewhere around 1 : 66

    (0.015 / 1 ) * x == (1 / 144)
    x == (1/144) / (0.015 / 1 )
    x == 1 / (144 * .015)
    x = 1 / 2.16

    I know this thread is kinda old but I was looking it over and I have my own sketch and I was wondering how you print out a 65 inch by 5 inch picture on a regular printer. I know I have to break it up but what’s an easy way to do that?

    Pretty much every printer I've used will automatically print it on multiple pages and then you can line it up by hand/eye pretty easily. You might have to mess around in your print settings but it should be pretty straight forward.
