Roger, This whole wood thing is really new to me but I can tell you how I cut a hole in the hood of my El Camino to accommodate a cold air package.
1. Determine the total diameter of the hole you want to cut. In my case I needed an 18" hole. 2. Divide this number by 2 this will give you diameter. 3. Find the dead center of the piece you want to remove. In my case I used two pieces of "Mechanics wire laid from opposite corners of the hood forming an X. Where the two wires intersected was the center of the hood. Because 1980 El Camino hoods are pretty much made of unobtanium I checked this measurement several times. 4. Drill a small hole at the dead center point. 5. Get a piece of flat strap slightly longer than the diameter of the circle you want to cut. 6. Drill the same sized hole in the flat strap you drilled at the center point of your circle. -7. Now take whatever cutting device you are going to use and remove the blade from it so that it will set flat on the material and position it with the blade chuck exactly where you want your cut and mark it. At this point secure the other end of the flat-strap to your center point 8. Pivot your flat strap guide around and attach it to your saw any way you are comfortable with. I already had a couple of holes drilled in the shoe of my saws-all and simply ran a flatheaded fastener through the strap and through the saw shoe and threaded on a nut and washer just tight enough to hold the saw steady. Now before you reinstall the blade or plug in the saw move it around your intended circle to make certain nothing slips or binds up on you. 9. Remember that mark you made in line with your blade chuck? Now drill a starting hole that your blade will fit through. With the other end of the flat-strap bolted in place Very carefully begin your cut around the circle. If ever there was a measure twice and cut once situation this is it. I understand we are working in different materials but hopefully this will at least give you some ideas. -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Rodger Hood Sent: Thursday, December 06, 2007 9:46 PM To: [email protected] Subject: [BlindHandyMan] cutting a circle Can anyone tell me how to cut a circle out of a sheet of plywood for a table? I have all the saws and tools for most things but am still learning from your shows how to use them in different ways. I need to make a few different jigs for different shapes and could enjoy hearing from you on how to make them. Thanks for your helping advice.
