while were on this subject I have a rotozip and I've tried several times to use it to cut MDF and it just does not work very well at all. Is there a special kid of bit that I should be using to make these cutouts ?

i knew there was some ideal way to cut rings with a router. i thought about attaching the thing to a scrap piece below but i didnt know if it would work out that well. i guess it will //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

i wish there was a better way to secure the ring down so it didnt move after you get to the end of the rip. i hate that little divot that is left at the end of the rip. i know about plunging as you swing through the rip, but meh.

ill give it a try.

i can't help with the router part but i have a Rotozip with a circle attachment that i use for that purpose....works freaking awesome

i had a rotozip, but it didnt have enough power. there are bits for drill presses. you can get them big, my school had them all the way up to 4''. work very nicely

No dude never plunge as you're making a pass. Plunge a certain depth at your starting point and then make that rip at that level. Once you make a full pass, then plunge slightly deeper (while NOT moving) and make the next pass.

For 3/4" wood I'd make 3 passes 1/4" deep (assuming a 1/4" spiral upcut bit).

meh, i just plunge the full 3/4 with a 1/4 spiral upcutting bit.

And you haven't snapped bits or punctured your spleen?? Lemme guess...no safety goggles either? //content.invisioncic.com/y282845/emoticons/eyebrow.gif.fe2c18d8720fe8c7eaed347b21ea05a5.gif

listen.

i do not want, nor do i have the money or space, for tons of one time use tools. i am not buying a $10 hole saw to cut one pair of tweeter baffles.

so stop fucking recommending them.

Just just to take it slow. Also do it in levels just like they said with a router. It's the same thing with my dremel. I used to use it and a circle guide to make the woofer cutouts. I just used a down spiral cutting bit. It took forever. If you apply too much pressure to go faster, you will just burn the bit. My router and jasper jig work much nicer.
