Fin Scale Up/Down

Featured Tip: All Previous Next

By Matthew Gillard

This tip is for an easy way to create fin templates for an upscale or downscale project - inspired by the 2008 challenge.

Drawing around the fin of the normal sized fin makes a template of a fin.

Then using a photocopier, select the reduction/enlargement function, and photocopy away. Best to make a few copies.

The result is a perfect downscaled template to create the new fins.

There is little point in doing this for straightforward rectangle or triangle fins but where you have a fin with difficult angles to copy it does speed things up.

The same principle can be applied with a scanner/printer.
