A Handplane Jig for Ladderback Chair Leg Tapering



Here's another hand tool jig. This one is more specific than the dovetail paring jig I showed in the last entry, because it's built to help with one particular step in one particular project. I use it to turn tapered square chair leg blanks into tapered octagons when I make the ladderback chair developed by J. Alexander and Drew Langsner. The dovetail jig can be used for joints of different thicknesses and widths, and I can even picture myself using it to fair up tenon shoulders. But this leg-tapering jig is so specific that I doubt it will ever be used for anything but this project.

First I'll show about making and using the jig, and then I'll explain my thinking a little bit.

Robert Ingham's Dovetail Paring Jig

I've been thinking lately about hand tool jigs for very specific operations. If you've used hand tools much, you've learned about the value of jigs for often-performed, generalized operations like making a square end on a board with a bench hook and/or shooting board. I'm thinking about more specialized jigs that don't get used for every single project, but come in handy for guiding a tool along a carefully limited path to produce consistent, accurate results. This baseline paring jig for dovetails is a perfect example.
