I measured it out to precisely 57mm and cut several holes in scrap material to check and make sure the saw was set to the right size. As long as I cut soft material (aluminum, wood, fiberglass... etc) it worked perfectly. |

It's only 0.006" bigger than 57 mm, and you'll never notice the difference. -- Eric Greenwell - Washington State, USA (change ".netto" to ".us" to email me) - "Transponders in Sailplanes - Feb/2010" also ADS-B, PCAS, Flarm http://tinyurl.com/yb3xywl - "A Guide to Self-launching Sailplane Operation Mar/2004" Much of what you need to know tinyurl.com/yfs7tnz |

what have others done when cutting new panels for 57mm instruments? 2 -1/4" holesaw for 57mm, 3-1/8" for 80mm... I have a set I only use for cutting instrument holes so they stay nice. -Paul |

J4 John, Go to http://www.craggyaero.com/ultimate.htm Download the 2.25" and 3.25 Instrument hole templates at the bottom of the page and follow the directions. A 2.25" hole saw will work fine mark the center hole as in the directions and us small pilot drills for starter holes then the 2.25" hole saw then the instrument screw holes. Make sure and use a punch to get the starter holes exact. Richard www.craggyaero.com |

You need a 1 1/4 inch size. Aircraft Spruce carries them. Here's a link: http://www.aircraftspruce.com/catalo.../knockout2.php. Charlie |

Charlie Charlie, I think you meant to type a 2 1/4 inch hole. 57MM equals 2.24 inches. Doug |
