I think I need some lessons on using a Dremel. I broke three of those disc-type bit pieces working with my husband's over the weekend trying to work on something for Gozer. Whoopsie
Not your fault, PB. Those thin, stone-like disks that come with the Dremel kit look like they're meant for cutting all sorts of things, but they're really pretty useless. They're okay for fairly soft metals like copper or aluminium, but even then you have to go carefully. With any other materials they will either break or get clogged up and become unusable. There's a good reason why they give you a whole stack of them - they're basically disposable.
Dremel does make very useful cutting disks, though they don't usually include them with the basic set. Look for rough, textured ones that are impregnated into a mesh (they're excellent for cutting steel and other metals), diamond grit disks (good for very fine cutting of metals), or fine-toothed circular saw blades, which are excellent for wood, plastic, bone, etc. Generally speaking, few of the bits that come with the Dremel are very useful, which is a poor choice by the company, because it must turn a lot of new users off the tool right from the start. I'd say the bits I use the most are the toothed saw, a couple of small, round burrs, and some tiny drill bits, all of which I had to buy separately.
On the home front, I've just made a ridiculously
cute item. I don't really know what it is, as the old catalogue I've copied it from doesn't properly identify it, but it was too sweet to pass up. I think even in full-scale it would be awfully charming.
