« Part 1: Mitre Jigs Part 2 of Jigs etc. series Part 3: Simple Circle Cutting Jig for the Routing Table »

Some of you have been wondering how I finish pieces to exactly 60° for my Impossible series. Basically I cut them to 60° on the tablesaw, a little oversize (experiment) and then finish sand them on the drum sander using this Jig. It works equally well on a planer/thicknesser.

Fairly simple to make. You take a rectangular section of timber (lumber). Shorter in thickness than the width of the piece you are planing/sanding. Set your tablesaw blade to precisely 60°. I use a vernier protractor these days but the kind of set square you find in a school geometry set works almost as well. Saw through the length roughly in the centre of the wood.

Flip one piece 180° lengthways, so that they both have their larger end downward.

And screw them to a piece of MDF. The next bit is very important. Attach an end stop at one end to prevent the timber you are planing/sanding from shooting back and hitting you in the gut (or worse). Like so

Its painful. I speak from experience. This end will obviously be the one closest to you and the back end as the work goes through your machine. Thats it. Just place the thing to be machined to 60° in it and plane/sand.

As my friend from comparethemeerkat.com would say ‘Simples!’

Sweet. Simple enough. I like it.

Someone ought to perform a comparison of a rotating power tool ejecting a piece of wood with a trebuchet, and see which will throw it farther.

Martyn,
Thanks for the idea of this jig, I tried this one with trapezoidal at 95 degrees and 85 degrees angle (yours 60 deg.) but I was not so sucessful. I just planed it manually which is more tiring and adjusted it with a filing, Your idea had put a light on my next move when I do the rectangular design. Now, I have already realized how really difficult those projects you do. A little mistake will let you do it again. In fact, I am very selective now with the wood I used. Endgrain cuts can easily breaks when cutting it to shape. Thanks for postiing your jigs.
Cheers,

-- Bert
