Paremetric Doweling Jig

The Parametric Doweling System

This is pretty self-explantory, but it's a way to transfer dowels from one workpiece to the other. I've never had much luck with dowel pins, but with these jigs I can usually get a pretty good fit. This is not intented to be a re-usable jig, every type of joint needs it's own jig.

Dowel distribution

By default the program will suggest a dowel distribution, using 4 dowels for the joint. It can be altered to using 1, 2 or any number of dowels you want. These automatic distributions

When joining stock of different sizes, you generally want to customizes your dowel placement, to get the correct offset or reveal in the project. Set the distribution to custom and dowel locations to where you want them.

distribution = "custom";
dowel_locations = [[0,0], [-10, 0], [10,0]];

The origin of the coordinate system is at the center of the jig. So [0,0] is exactly at the middle of the jig.
