loking for a device to enlarge a pattern by tracing it? Answered



A pantograph is nice for tracing an outline quickly, but it might be more than you need. If you want to greatly enlarge a pattern, the grid method is the way to go: You draw a small grid across your small image, a big grid across your big surface, and copy the shape you see in each small square to the corresponding big square.

see attached image for the deadly easy version using cardboard and tacks.


Same principle, but instead of a pen, you use a router to carve the pattern into wood. Skip to the last half to see it in use.
