dustman Posted September 19, 2011 Report Share Posted September 19, 2011 I am a member of an online blind woodworking group (http://ww4b.org/). We have been discussing cutting octagons. We hsave a lot of smart guys and they have the math down great. I found several jigs for cutting octagons including the one at Fine Woodworking. If you cut octagons what method do you use to ensure equal sides. Quote Link to comment Share on other sites More sharing options...
konkers Posted September 19, 2011 Report Share Posted September 19, 2011 I good first question to answer how equal they need to be. What are you using the octagon for? If it's for a table top it just needs to look equal. If it's a piece of something more complicated you might need it more exact. Quote Link to comment Share on other sites More sharing options...
dustman Posted September 19, 2011 Author Report Share Posted September 19, 2011 It is critical that all sides are the same lenght. I am making small sewing boxes with a fixed top and bottom with one or two drawers in the sides. Would like to be with in a 1/32 of an inch.

Onboard Posted September 19, 2011 Report Share Posted September 19, 2011 Here’s a jig to consider. Quote Link to comment Share on other sites More sharing options...
cpw Posted September 19, 2011 Report Share Posted September 19, 2011 If you need to do production (several pieces) then I would consider Onboard's jig. If I only needed to make one or two I would use this method and make an extension for my miter gauge to do it on the table saw. 1 Quote Link to comment Share on other sites More sharing options...
Josh Dick Posted October 28, 2012 Report Share Posted October 28, 2012 I made a Dubby style sled. Basically, the back rail pivots from perpendicular to the blade all the way up to about 15* from the blade. The nice thing is with a 4' long pivot arm, it's really easy to dial in the exact angle.
