It is incredibly quiet, and takes up almost no space on my counter. With the 3M's I don't have the need to use an exhaust system as there is no tripoli or rouge flying about. Of course, it would be best to have one hooked up, but for the time being I'm good.
You can use the 3M's on your regular foredom flex shaft, but the bench lathe is sooooo much quicker, and you've got both hands to hold your item. Speed and efficiency.....Yeaaaaaah!
I got mine at Rio Grande www.riogrande.com. LOVE THEM!
