I'm sure someone has tried this before. I was wondering if it would be worth the effort to sand the cone (thin it) in certain areas to enhance volume or tone?

I haven't really heard of anyone doing that, but it probably wouldn't hurt, as long as the spider isn't weakened.

Silly me. I thought you were talking about sanding the spider.

Most quality cones are about .010"-.012" thick, maybe even thinner in some areas, depending upon the cone spinners amount of expertise and consistency while spinning. This doesn't leave you a lot of room for error. But, hey, it's your cone. Have at it, and let us know the results!

Come to think of it, I have run across some imported cones that could use some thinning. They are noticeably heavier than domestic cones I have used. I don't know how you would go about sanding it though, and keeping your results consistent across the cone.

Good Luck!

Well I took sandpaper to my cone and removed all the ridges from both sides and polished it with fine steel wool. I remove quite a bit of metal judging by the little pile of aluminum dust on my table. I also filed off most of the black paint from the spider and deburred it and installed new strings. I really expected the tone to brighten the tone, but it all seemed to add a little more depth to the tone instead and increased the volume a little. I did notice the spider went from a muted “dank” sound when I held it by the end of a leg and struck it with a screwdriver before I removed the paint to a soft sustained “ding” afterwards. I guess there was enough paint on there to kill the ring.
