How do you cut exact 10 to 14 inch circles in plywood with common tools. If not common than something cheap?
Ken B asked:
I need to cut round slabs of 3/4 plywood. I have almost all the common power tools.

rotozip cant think of how to do it with common tools. cjc419
Do you have a good jigsaw? Cut off much of the excess wood first using whatever you’ve got, then go to your jigsaw and do the final cutting all around, nice and slow.
If you need them perfectly round, finish up with a file and some sandpaper to smooth out any edges. mycathouse
Jig saw paultewing
Just use a Jig Saw its the easiest way. Once you have the circles drawn onto the plywood. Kris D
jigsaw….common as muck….sorted
but then if you need to ask this question
i think you should get someone to cut it for you MARK B
You can us a string … a jig saw..and a nail…Nail the string in the center and tie it to your jig saw boscowood
Mark the center and use a string and sharp pencil to trace the circle. Carefully cut out the circle with a skill or band saw. Finish with a belt sander. I have made a number of table tops this way. yes_its_me
Tie a 10″ or 14″ string to a pencil at one end and a nail at the other. Put the nail end in the plywood, use the pencil end to draw the circle. Hold on to the nail end very tightly. You can use a circular saw to cut out the circle. mrsdeli
I made myself a compass out of a scrap of wood and a nail tacked at the center, and used the end of the wood strip right up against the fence of a scroll saw). kay
tape a pencil to one end of a ruler. tape a second pencil ten inches down the same ruler. hold one pencil in place and draw your circle with the other pencil. do the same thing for the 14 inch circle, but you will need a larger ruler or just use a piece of something and measure out 14 inches. then use a coping saw to cut out the circles you made. yonitan
Some of the answers you got were correct regarding the string and nail, and jigsaw.
HOWEVER : they were giving wrong dimentions. If you are looking for a 10 to 14 inch circle, that would be the “diameter”, you need the “radius”, which would be half of that, or 5″ or 7″; then a file and sandpaper. gramps
jig saw and circle pattern Anti–Parrot
I would use a jig saw,for a 10 inch hole use a nail, find about where your center would be drive the nail in ,tie a piece of string measure it to 5 inches,,tie to end of a pencil draw your circle,,from center point to pencil is 5 inches,then of course this will give you a 10 circle,, half of 10 is 5,,half of 14 is 7,,,,,,and so on , you get the idea. have fun. you can do it !!!! little eagle
draw the circles to the correct dimensions. Using a circular saw, most people call it a skill saw, cut out the circles making 4 cuts tangent to the circle, if done correctly you now have a square with a circle inside it. continue making cuts tangent to the circle until you have most of the material removed then sand away the rest. Hope this helps. luther
If you don’t have a circle cutter in a drill press, then a jig saw is the quickest way, unless you have a bandsaw. cowboydoc
