Pyramid Angles

I wish to build a pyramid form witn an 8" base and 8" heigth.  I'm a bit confused as to how to set my blade and miter angles.  Can anyone help?  Thanks.

Re: Pyramid Angles

I would definitely use a birdsmouth router bit. They eliminate many of the math issues in such a project.

Birdsmouth joinery bits.

Re: Pyramid Angles

Hi Everyone,

 

Definitely a neat calculator and helpful too since the picture in Sylvio's original post made my head hurt (I swear I knew how to figure that out at one point...ah, old age, ain't it grand?).

 

Question for everyone though....and this may be a bit academic.  But the calculator appears to report angles to the second or third decimal place.  I don't think most woodworking equipment is that precise so is there concern on your part that this project will be, for lack of a better term, gappy? 

 

I have no idea, just a thought...and Sylvio you're far more brave than me...I'm not sure I'd try something like this.  Good luck with it!

If your angle is going to be off a little bit, just make certain that it's the long points that meet first. They don't have to be perfect if you're never going to see the inside. And we really are litterally splitting hairs here.
