is there a tool for cutting perfect round circles in 3/4" mdf, like 7 or 9 or 14 inch diameter circles? im tired of making nasty cut circles with my jig saw for mounting my subs into mdf...
is there anything better than a jig saw?

A plunge router with a circle guide base, if you need total accuracy, a RotoZip with circle guide attachment will do as well.

Buy a good circle cutting jig to attach to a router (hopefully you have a router already). I suggest a Jasper circle jig. You can check them out at http://www.jasperaudio.com
OR if you don't have a router, and don't want to buy one, get a circle jig for your jigsaw (or build one), which allows you to drill a center pilot hole, and then you can just run the jigsaw around in a nice perfect circle.

Good Luck.

yes, i already have a router. those jasper products look very promising, so it looks like thats the way to go. they will even make holes big enough for 18" inch subs.. if i ever go that big...

thanks for the replys

the Rotozip's are less expensive than a rotor. they don't work AS well, but do a great job. but if you already have a rotor, i'd just get the attachment.

Yep I would go with the circle jig for your router.

A router can be had for anywhere from about $40 (cheaper units) on up to several hundred dollars, the circle cutting jig can be had from $29.95 to about $100 (depends on what you get, and where). if you're on a tight tight budget but want tools really bad, you can try hitting the pawn shops. We used to sell nice routers that retailed for $259 for like a one third that price, sometimes less, and they were still in excellent condition.

Table saw, anywhere from a few hundred to several thousand. Just threw that in because a table saw is one of the most important tools you can own in my opinion.
You can however get away with some sawhorses and a circular saw, and straight edge cutting guide. hehe

well turns out my router isnt a plunge router, just a plain ole router. i think the circular jig will still work, but it will be more difficult to use. im gonna stick with my jig saw for now, and save up some bucks for a nice plunge router in the future..

Well I just bought a jig saw yesterday. I also started working on my custom dash piece for my car. Don't know if I'm doing it right though. Thanks for the help
