HOW to: Draw perfect circle?

[gigabit 10+ year member]

the search function didn't yield any results for me, sorry if this is a repeat question.

my speaker didn't include a cutout for the speaker cut-out slot on the box which im going to make.

how did you guys go about drawing a circle for your speaker cut out? i have the eD 13av.2.

Thanks!

A compass works when you're in a pinch.

compass, ruler with holes drilled in it, find something with the same diameter of the circle you want... there are tons of ways to draw a circle. maybe you should have someone build your box for you

String and pencil work well too. But I would rather use a compass.

make your own compass. i use a scrap piece of mdf. put a nail in it where the center point of the subwoofer is goint go to and measure the radius out and drill a hole. stick a pencil in that hole and rotate the piece of mdf to draw out your circle.

I politely disagree. Everyone should start making their own boxes if they want. It's a good learning experience and can be quite fun.

Best of luck //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

thanks guys. i have made 1 box previously but it was convenient b/c image dynamics gave me a cut out.

im going to try some of those suggested ideas to see what works best.

Thumbs up.

A perfect circle isnt the problem, cutting that perfect circle has always been my problem.

I dont mess with wood often enough for it to make sense buying a router and a Jasper jig, so the circles dont come out perfect.

just use a router it will cut a good circle

String and a pencil work good
