What router bits do i need to make a circle?  My friend has a router, we made a circle jig, but i'm curious as to what bits i should get.  (haven't gotten a chance to look around in the stores yet)

thanks in advance,,,

If your cutting a trim ring use a flush trim bit ( probably a 1" or longer ) and if your using it to get one with a bearing on the end and a 3/8" should do. Make sure that the shaft width is correct too. Most home use router's use a 1/4" shank.

This could be a easier,i dunno though..if you dont have a router.

make your base,where the subs go..and have it bigger so that the sub is flush with the board..then have a smaller board that is attached to the bigger top board and cut your sub size hole in the smaller one..kinda would look like you did it with a router. Then your base board will be thicker and can hold the power.

Hope you can understand that conept.subwoofer 'ring' cutouts.. -- posted image.

I need quality equipment, feel free to donate.

I think Maxst is talking about recessing the sub. I've seen it before, and it looks pretty cool at times (and if it's done right). You would have to take into account a seal ring (that comes with some subs), or some kind of sealent material (I've seen foam used before) between the sub and the wood to keep it air-tight.
The whole point behind using a router though for any enclosure opening is to have a nice, neat, hole. Not jagged like you would get with a jigsaw. So even with recessing the sub like Maxst said, you would still need a router to keep the openings as clean looking as possible.

You don't want a bit with a bearing on the end to drop through the board with a jig. Also, get a bit that has a small diameter, just a little bit bigger than the shaft size will do best. Less material to cut out when doing a cut.

Sorry, you can NOT post a reply.
