Spirograph is a drawing toy that was invented during the 60’s by Denys Fisher. it allows drawing some really cool shapes on paper. check the online version of that, lots of fun – http://nathanfriend.io/inspirograph/
Pantograph is a mechanical linkage that allows tracing a shape down to scale. in my case, I’m using 3-d router pantograph, built after Matthias Wandel’s plans. it allows to copy a shape in 1:2 or 1:3 scaling. in this case is used 1:2 ratio.
Combining these too together will give you some cool carving effects. the video below explains the whole process, which is quite simple:
the Spirograph is made from 4mm acrylic sheet, cut by laser cutting machine (the same machine that produces rubber stamps, can be found in almost any print shop). I designed the Spirograph’s gears on Matthias Wandel gear template generator program. note to self: next time make it with transperent acrylic.
The possibilities are almost infinite. every hole will give a different design, and i can use any combination with the 6 gears i already made. cutting more gears will increase the possibilities even more.
Thanks for watching.
