I'm assuming that you will be making a pinhole from pie pan aluminum (or something like that), then affixing it to the inside of the cannister over the larger hole. That being the case, I would think that just about anything would work - perhaps use a pencil to make the hole, then use sandpaper to smooth the burrs.

Re: [pinhole-discussion] Cutting oatmeal box
If you're worried about safety, I'd just cut the holes before the students get there. A Dremel might work, maybe a drill with a forstener bit in it, but I'd be more worried about safety with all these powertools - especially since you're drilling something cylindrical.

Re: [pinhole-discussion] Cutting oatmeal box
I have a Dremel tool that I got from my father. I've been looking into using it for drilling a clean hole. I just purchased a set of drill bits (sizes 61-80) for a Dremel tools. When I went to use it, I found that the chuck (or collett or whatever) did not go small emough to hold the small drills, so I am looking at buying a new chuck that can take the drills. The smallest bit goes down to 0.013 I got an email this morning from a supplier, and I think I might have found what I need. All of this can be found at http://www.widgetsupply.com Once I get the thing working correctly, I'll drop a note about this. Fortunately, the pieces are pretty cheap. The shipping is a major part of the cost. Bill Leigh --- Chris Harris cpharrisph...@hotmail.com wrote: I'll be teaching a pinhole class, constructing cameras from Quaker oatmeal canisters.

How about a punch? If you were to insert a piece of soft wood (like a 2x4 clamped to the edge of a table) into the oatmeal box for a mandrel, you could smack a short piece of brass tubing (or anything else you could find lying around) with a hammer and punch out a pretty good circular hole--especially if you filed the edges of the tube to make it slightly sharp (but not skin-cutting sharp). The above is much like a cork-borer. This is a tube with one end sharpened to bore a hole in a cork. You may be able to get one at a very good hardware store or from a scientific supply house - maybe even a wine-making store. We have a couple of sets of them for making different sized holes in corks and stoppers. They should cut through cardboard Gord - Gordon J.

Another possibility would be to use a circle template, a mandrel like above, and a ball-point pen. Use the template to draw a circle on the cannister in the desired spot, and then keep going around and around using the template as a guide, bearing down hard with the pen...soon enough you'll come through the other side. A little time consuming, but pretty safe--I'm not sure you couldn't do as much damage with a Dremel as with a knife! Cheers, Chad
