John, I found this on the net DIY Network: Tools DIY Network URL: http://www.diynet.com/diy/hi_tools/article/0,2037,DIY_13936_3955092,00.html Using a Micro-Adjustable Miter Gauge >From " DIY Tools & Techniques" episode DIT-308 -- More Projects ยป
A standard miter gauge on a table saw doesn't always make perfect miters. They're not designed to be fine cut tools. They are rough cut tools. In this segment, host David Thiel demonstrates a commercially available micro-adjustable miter gauge that increases the accuracy and fit of miter cuts on the table saw. Continued below. PHOTO Figure A PHOTO Figure B PHOTO Figure C PHOTO Figure D PHOTO Figure E list of 5 items . A stock miter gauge doesn't always fit tightly into the miter slot. A slight left or right shift of the miter gauge inside the slot during a cut can be a cause of imperfect miters. Also, if you pull the miter gauge back to make a deep cut, the miter gauge may lift up out of the slot. This can also cause imperfect miters. Some stock miter gauges only have 3 preset angles. The markings are set far apart, making it difficult to achieve a precise angle (figure A). . You can see a slight gap in a cut made with a stock miter gauge, as opposed to the cut at the top of the picture (figure B), which was done with a micro-adjustable miter gauge. A micro-adjustable miter gauge has features that solve the problems of creating miter cuts on a table saw. It has an Allen set screw in the center of the bar the gauge can be tightened into the miter slot. A washer fits into the groove in the miter slot to prevent it from tilting upward when you pull it back to make a deep cut (figure C). . This gauge has positive stops at every degree to help you achieve the accuracy needed to create perfect miters. . This gauge has several preset angles for you to use. If you're trying to make a shape out of a certain number of pieces, you can check the guide on the miter gauge to tell you what angle you need to use for your cuts (figure D). . The micro-adjustable gauge has its own fence that slides left to right so that you can get a tight cut right up to the blade. You can extend the fence so you can cut longer pieces more accurately (figure E). The stop on the gauge allows you to make several cuts the exact same length. It can also be used with the extension. Flip the stop up to keep it out of the way when not in use. list end RESOURCES : Hitachi Table Saw (C10FL) Hitachi Power Tools Websites: www.hitachi.us.com or www.hitachipowertools.com Osborne Precision Miter Gauge Excalibur - A Sommerville Design Sommerville Design & Manufacturing Inc.

I'm trying to find a better miter gauge for my Hitachi table saw, but my slots seem to be nonstandard. My present gauge is 14 inches long and 5/16 inches thick. The bottom of the bar is 5/8 inches wide and the top of the bar is 7/16 wide. The bottom is 3/16 thick and the top part is 1/8 thick. Does anyone know where I can get one? I have googled it and looked on some of the sites but they all seem to sell the standard size. John -- No virus found in this outgoing message. Checked by AVG Free Edition.
