Another caution from personal experience:
If you're going to use one of these cutters, even in a drillpress, be sure to remember to slow the drillpress down to it's slowest speed, and be very, very, careful about clamping your work on the table. Rmember that things are going to vibrate and possibly move, so be absolutely sure to tighten all the clamps and drill press adjustment knobs. Even at the slowest speed, that cutter is really traveling fast, and it's very unforgiving. -----Original Message----- From: blindhandyman@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Tom Fowle Sent: Sunday, May 25, 2008 10:07 To: blindhandyman@yahoogroups.com Subject: Re: [BlindHandyMan] cutting a circular hole A fly cutter looks like a drill bit with an arm sticking out of the shank of the bit. Thereis a second cutter fasten to this arm on a sliding arrangement. You adjust the distance between the main bit, center, and this extra cutter for the radius of your hole. Since the entire thing is off centeer and unballanced, it is unsafe to use it in anything but a drill press that, as Dale says, keeps it ballanced and true. You got this arm and cutter flying around in circles right out there with nothing between it and your body. I wouldn't even use one in a drill press. There are similar, smaller, devices, I think called adjustable bits, for a brace which you crank by hand. Not so bad as you have control and it's slow. NNot sure they come as big as 2 inches. If I had to do this job on the cheap, I'd do it with the marked hole and many 1/4 inch hole method and a gouge. |tom [Non-text portions of this message have been removed]
