I purchased a small bending brake from Grizzly.com to make small bends (24" and less) and it has a sharp edge for steel. I was wondering if I could just go at it with a file and end up with an edge pretty close to 1/8" radius. The advertisement claims: "Bending is quick and easy with this little brute! A favorite with our home built aircraft customers." Any thoughts on whether using a file is a good idea or not? The brake can be seen at: http://www.grizzly.com/products/item.cfm?itemnumber=H2788&site=grizzly Thanks, Scott Laughlin 601XL, Omaha, NE Working on Elevator Ribs ________________________________ Message 4 _____________________________________ Time: 07:36:52 PM PST US From: "paulrod36" Subject: Re: Zenith-List: 6.5 mm reamer --> Zenith-List message posted by: "paulrod36" I just finished doing the bellcrank pivot, which comes with a 1/4" hole, but AN3 bolt to go through the bellcrank and supports. --- I bought a foot of 3/16 ID, 5/16 OD tube from Airparts, then drilled (using a drillpress for accuracy) a 5/16 hole in the bellcrank. I then cut about 2" of tube, put it in the drillpress, and turned it against a file until I had a snug (not sloppy) fit. Cut to the proper length with a hacksaw while turning in the drillpress (poor man's lathe) it rests inside nicely. The AN3 bolt slides in perfectly, already fitting the bellcrank support holes. A little lube before assembly, and it should last a long time. ----- Original Message ----- From: "Larry C.

Had the standard wooden prop (68" dia) reduced to 66" for my installation. Works fine.
