Today I had to make a conical Chinese hat, as its sort of called here, at a 5/12 pitch. Basically a cone shaped roof jack 6" on the bottom and 4 on the top angled to accomodate a 5/12 ptch. Had to do it in a HURRY....not good! I used the process for laying out a cone with the top cut off at 70 degrees and simply moved that angle to the bottom of my layout and pulled true legnths from there. Its difficult to explain....but it worked. I plan to visit the library and find the proper method.
Speaking of rolling and cone hats....can you roll a cone hat in a slip roller. I think I sed to do it but do not recall how. |

I know I asked this before and I kinow I can't vist regularly but is there a short method to laying cones out on a pitch? I manage it but my method is ify and slow. I checked the libray vut I guess I missed the layout. I can't really make and keep a template since no two ever seem to be the same. Help please!

I put together some material that will be in the Cone using the Short Cut method July issue of Snips. Send me your email address and I'll send you a copy tonight for you to read.
This is one way, and it's a bit more accurate then rolling the pattern. Here are a couple of images that are included in the instructions.
Edited-
(Sorry - I missed the part where you mentioned that you can't make the template) |

I have this book - I'll see why it's not in the library? It should be. |
