Rep Power: 0 cutting out spacers/ cutting sheet metal
I have a dremel and it came with the circle cutting guide. Has anyone here made mdf spacers using their dremel and a circle cutting guide? If so what bit did you use to cut? Or what tool works best to make an mdf spacer?
Also for cutting sheet metal, what dremel bit works best? I have a few bits that are for cutting metal (a grey circular bit that looks like it is for sanding).

Rep Power: 0 For spacers, I've always used the jigsaw and a router table... I only use the dremel for small spaces or sanding.. (the sanding wheel works great)
For sheet metal, you COULD use the cutting wheel but depending on what type of metal and how thick it is, you'll be going through the wheels like crazy.. and theyre definitely not cheap enough to be doing that. Use sheet metal cutters/tin snips.. they work great.

Rep Power: 303 I used my rotozip and circle cutting guide one time (it's the same pretty much) and it always gave a lumpy circle, not a perfect circle because the bit could move just a small amount. If you're ont a perfectionist, then it'd be fine.

Rep Power: 286 I have a perfect circle cutter - like a dremel only considerably bigger and 10 x more powerfull. It has a router attachement and a hand guide attatchment as well. It makes perfect, smooth circles. I bet you'd get a slightly lumpy circle from a regular dremel like pop said. Use the bit that looks like a drill bit but says it's for cutting steel and go slow with it.
Paradox, if you are having a hard time drawing good circles, you need to get a compass. Then all you have to do is measure the diameter of the speaker, subtract 2 x the distance from the basket to the outer lip, and then you'll have your inside diameter. Divide it by 2, set your compass and mark off the dead center of intended cirlcle. Push the sharp end of the compass into the center pretty good and trace around the circle and your done. Alternatively, some speakers when you buy them new will come cardboard templates either in or on the box. Also, some speakers have mounting rings that serve as guides as well.

Rep Power: 303 Lay your speaker upside down on the board. Trace around it, there's the outside. Find the center and put a nail in it find anything that you can nail in the center and attace a pencil to (a piece of scrap wood with 2 holes drilled in it works fine)
