This auction is for a Bridge City Tool Works BP-18 Bevel Protractor.I have used this tool a few times and there is some light surface rust as shown in the pictures.This tool is no longer being made by Bridge City, so don't miss this opportunity to get this one for your shop!The following is the description from the Bridge City website:The BP-18 Bevel Protractor consists of nine components. The main protractor scale is etched on a plate of satin chromed, hardened steel (Rc 54) which is nine inches in length, just under six inches in height and is seventy thousandths thick (this is roughly twice as thick as our precision rules). The precision protractor scale is photochemically etched (the most accurate method available today) and is black filled for an easy read. And it reads direct to one half degrees and you can extrapolate to one quarter degree!The BP-18 Bevel Protractor uses an eighteen inch indicator. Made from the same hardened and plated steel as the protractor plate, this pivot arm contains the hairline cursor (beveled to avoid parallax errors) by which you set angles. The length of this arm will allow you to layout many of your angles directly without the need of transferring to another bevel. This saves you time, improves your accuracy and is particularly useful in setting up table saw miter gages!The heart of this tool is a brass and steel pivot mechanism (patent pending) that allows our tool makers to calibrate this tool to a perfect 90 degree setting. This ability negates the inaccuracies of hole and cursor variations. Lastly, a bevel setting is not worth a hoot if it is easily bumped out of alignment. Our BP-18 Bevel Protractor locks at the point of pivot and there is a secondary locking mechanism up the arm for total stability of your settings. These features create an incredibly accurate and extraordinarily useful shop aid.Another of the handy features of the Bevel Protractor are adjacent measuring scales on the top and left edges. For those of you who occasionally need a scale that reads in tenths or twentieths, here it is. The top scale reads left to right by sixteenths and is very useful for setting up machine fences. These two scales can be used together to obtain ratio settings. For example, if you need to make a dovetail profile that is 7:1, set your T-bevel on the one-inch mark on one scale, and the seven-inch mark on the other! it's easy, fast andaccurate!The back face of the BP-18 Bevel Protractor has not gone to waste either. It contains many of the most useful shop formulas pertaining to circle geometry. What better place to make this information available than on the very tool that will use it! Included with the circle geometry formulas are rise, run and pitch formulas and an English/metric conversion table. All are photochemically etched into the steel, black filled and will not wear off.The BP-18 Bevel Protractor can be used independently or in conjunction with another adjustable bevel. Traditionally you would set the bevel protractor at the chosen angle and transfer the setting to a T-bevel that will allow you to set machines to acute or obtuse angles. Since both edges of the BP-18 Bevel Protractor are accurate to the indicator, this is the perfect tool for setting our AS-24 Adjustable Angle Square!The Woodworker's Guide to Compound Miters that contains all the compound angle settings for the table or radial arm saw which will give you an incredible lift in capability. These numbers are extremely difficult to calculate on your own and are even harder to find!For example, let's say you want to make a seven-sided box with the sides at an eleven degree angle . At what angle do you set your blade? At what angle do you set the miter gage? Hundreds of problems like this are easily tackled with The Woodworker's Guide to Compound Miters which is included.US Sales only. Payment via Paypal within 3 days of auction end.
