Behind the Book:
The idea of Compound Miter the bevel and miter answer book started with my goal to place within the hands of a craftsman all the answers needed to accomplish every compound miter joint in question. The structure of the book is base upon any inside and outside corner angle 0° thru 360°, with each of these corner angles in increments of 1°, matched with any spring angle, 0° thru 360° in increments of 1°, placed within tables called Finding Bevel And Miter Angles. During the writings of Compound Miter the bevel and miter answer book, one’s goal was to accomplish all answers to all compound miter joints in question. The basic formula throughout the book is; I.C. or O.C. w/ S.A = B.A and M.A... Any inside corner angle (I.C.) or any outside corner angle (O.C. with any spring angle (w/ S.A) equals the bevel angle saw setting (B.A.) and miter angle saw setting (M.A.).
Prior to the tables within Compound Miter the bevel and miter answer book I care to share a speed search layout design placed within all the tables throughout the book called Quick Tabs. Located on all four corners of each page, one table per page, are two diagonally crisscrossed sets of tabs with each diagonal being in the same of value. The placement of Quick Tabs throughout all of the pages within Compound Miter the bevel and miter answer book provided a craftsman the ability to speed search pages one table per page, locating any known existing construction or any desired new construction answers. Quick Tabs within all four corners provided the craftsman to speed search the Quick Tabs while flipping pages to the left or flipping pages to the right.
Finding the answers to any bevel angle saw setting or miter angle saw setting within Compound Miter the bevel and miter answer book takes just a few steps. Locate the Finding Miter And Bevel Angles pages the table titled in Quick Tabs after the existing construction or desired new construction inside or outside corner angle. Locate within the same table an existing construction or desired new construction spring angle. Find below the spring angle the miter angle saw setting as well as the bevel angle saw setting answers.
Do note; should any inside corner angle, outside corner angle, or any spring angle be unknown within the search for any bevel angle saw setting or miter angle saw setting in question. Compound Miter the bevel and miter answer book contains a complete sets of tables to answers all inside corner angles, all outside corner angles as well as all spring angles through a few simple steps of taking measurements.
Located throughout the Finding Miter And Bevel Angles pages there are strikethroughs of some bevel angle saw setting answers as well as some miter angle saw setting answers. The strikethroughs are placed within a basic compound miter saw angle range of 45° miter angle or 45° bevel angle. This is a quick reference guide on which cuts can be made on a compound miter saw and which cuts would need a different piece of equipment such as a table saw with the material in a vertical position. Thus allowing the craftsman to make a decision on how or could they accomplish the compound miter cut prior to starting the project with the equipment on hand.
An example to finding an unknown spring angle whether it’s an existing construction or desired new construction spring angle is to locate within the Finding Spring Angles pages the table titled in Quick Tabs after the existing construction or desired new construction material dimensional rise. Locate within the same table an existing construction or desired new construction material dimensional run. Find below the material’s dimensional rise and run the spring angle in question answer.
An example to finding an inside corner angle or outside corner angle whether it’s an existing construction or desired new construction spring angle is just few measuring steps of a triangle. While using a triangle with two leg lengths the same called adjacent and opposite at 12in, 30.5cm or 304.8mm, by measuring across the outer end points of the adjacent and opposite legs is the hypotenuse dimension. Locate the hypotenuse dimension found in the Finding Inside Corner And Outside Corner Angles tables, above in column is the inside and outside corner angle.
Note that using a matched to 12in dimension or centimeters and millimeters throughout the Finding Inside Corner And Outside Corner Angles tables allows Compound Miter the bevel and miter answer book to be used by either an imperial tape measure or metric tape measure situations. Should any answer in inches, centimeters and millimeters be in need of converting back to another, Compound Miter the bevel and miter answer book provide tables within called Converting Decimals To Fractions as well as Quick Tape-Measure Conversions.
An example of finding the answers to any square-cut rafter’s spring angles useful during compound miter soffits fascia installations at square-cut rafters is to locate within the Finding Square-Cut Rafter’s Spring Angles pages the table titled in Quick Tabs having the existing construction or desired new construction dimension on twelve roof pitch. Locate within the same table below the existing construction or desired new construction dimension on twelve roof pitches Below the roof pitch used is the square-cut rafter’s spring angle, spring to level front and spring to level rear as well.
Located within Compound Miter the bevel and miter answer book is material working steps for cutting crown molding using a single bevel miter saw, cutting crown molding using a double bevel miter saw, cutting compound miter joints, using a single bevel miter saw as well as cutting compound miter joints, using a double bevel miter saw.
As these material working steps are based around either single bevel compound miter saws as well as double bevel compound miter saws do note: Compound Miter the bevel and miter answer book wasn’t written around a specific piece of equipment such as a compound miter saw. It was in fact written around any piece of equipment that would accomplish any bevel angle saw settings as well as all miter angle saw settings to complete any compound miter joint in question. These material working steps are placed within Compound Miter the bevel and miter answer book as an addition to helping a craftsman within the field.
All of the material working charts are in six easy steps. The steps provided for cutting crown molding joints range from identifying top and bottom of the molding, to placing the molding on the saw, to which edge gets fenced, to the miter angle saw setting, to the bevel angle saw setting, to which piece of the molding is used for the installation, which piece of the molding is the drop, while the steps provided for cutting compound miter joints range from identifying top and bottom of the material, to placing the material on the saw, to which edge gets fenced, to the miter angle saw setting, to the bevel angle saw setting, to which piece of the material is used for the installation, which piece of the material is the drop.
Without a doubt most crown molding joints are compound miter joints yet not all compound miter joints are crown moldings. Quoting the word “most” crown molding joints as should an installation of crown molding require the material to be installed at either 0° or 90° the joint is considered a miter joint. Yet s the book wasn’t written around cutting crown moldings as compound miters, it was written to accomplish cutting all material as a compound miters such as flat stocks, moldings with an identical reveal on both edges, multiple spring angles positions during installation, etc.
I’ve been asked while designing this book, when would you ever need the answers to a three degree inside corner with an eighty seven degree spring angle, or any other angles out of the norm? Chances would be slim to none, yet when needed the answers are there. The goal throughout writing this book was any corner angle with any spring angle is the answers needed to accomplish any compound miter cut and I stuck with my goal all the way through. I’ve also found in throughout my research the standard 52°/38° and 45°/45° spring angles for crown molding is the basics of what’s being used on compound miter saws today, besides using the equipment as a chop saw as well. This book will expand the craftsman’s usage of the compound miter saw and other cutting equipment, as the answers to any compound miter cut are there for the craftsman’s use for a wider variety of ideas throughout working of material and installations.
