Having not thought thru the project completely, When you angle them up, it changes the angle of the miter needed to get them to fit properly. Hence my web page, which tells you the right angle for the *final* upward angle. As for *making* the cuts, I use an Incra 5000 and t-track clamps. |

I plugged in
number of sides 6 angle of sides 45 just to see if I could figure out what this is all about. This is what I got. cross cut angle 22.2 blade angle 20.7 So if I set the blade at 20.7, and set a mitre of 22.2, and cut pieces to a sharp point, and arrranged them in a circular pattern I'd get a roof? I have never used a chart, nor understand it (them). Is this a specific type of chart for circles, or is this the same type of chart you would likely see at the back of textbooks? I'm gonna try 0 and 90 with 6 sides: 0 (flat) gives 30,0 90 gives 0,30 I definetely don't understand. ----== Posted via Newsfeeds.Com - Unlimited-Unrestricted-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |

I'm gonna try 0 and 90 with 6 sides: 0 (flat) gives 30,0 Yes. Assuming you're using plywood for this example, you'd end up with six triangles with square edges, which form a flat "circle" when combined. 90 gives 0,30 I definetely don't understand. 90 means they're all standing up. If you cut out big squares with 30 degree bevels on each edge, you'd end up with, essentially, a six-sided box, without a top or bottom. To avoid confusion, consider a four sided box with mitered edges. You'd use a 90 degree setting on the crosscut miter, and the blade would be angled 45 degrees. Nice box, yes? But if you set the miter at 45 and the blade at 90, you wouldn't get a box, you'd get a picture frame. You want something halfway between a box and a picture frame :-) |
