Enlarge drawings with a home-made pantograph

[@lithostheory]

And then use it again to get 4x original size and again and again... before you know it you have a dog as large as the earth :)

[@makismakiavelis5718]

Yeah, I could but I'm too lazy to do this like... 28 times?

[@viciousKev]

If god can do anything, can he make a drawing of a dog not even he could double in size?

[@lithostheory]

Lets see, if the original is 5 cm then n times doubling the size gives a total size of 5 cm * 2^n setting this equal to the diameter of earth which is 12.742 km or ~1.2e9 cm. Thus 5*2^n = 1.2e9 --> 2^n = 2.5e8 --> n = log2(2.5e8) --> n = log10(2.5e8)/log10(2) =~ 27.9 so indeed 28 times should do it!

[@EdwardChan.999]

You'll stop at some point, unless you make a larger ruler set, before the enlarged drawing can be duplicated. (the original ruler set will eventually be too small to duplicate large drawings)

[@roucoupse]

My parents bought me one for Christmas when I was a child. I had asked them so many times and I was dreaming of it all the time until Christmas, I couldn't believe all the drawings I will be able to replicate, and what more, on even bigger formats. When Christmas arrived, I unwrapped the present and went to play with my pantograph. I felt disappointed. Although it was sturdy enough, I felt like It was a piece of rubbish, I didn't manage to have good drawings with it. In practicality, the pantograph wasn't at all what I had dreamt about.

Why use the paperclip to melt the holes only to make them larger later? - Use the nail to melt the hole?

[@Goaty-nb3wg]

To be more accurate, it's something Carpenters do

[@thechopstickkid]

Because if you over heat the nail then the plastic would create a larger hole due to the surrounding heat of the nail

[@01rai01]

He said the fit should be snug, the hole will be slightly bigger than the screw used to melt the diameter of the hole.
