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.

I have that configuration and although I don't use it for pinhole making, I have used it in the past and it works (sort of). Just have in mind the hole may not be exactly the size of the drill and will have lots of burrs around them. Guillermo
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 wrote: > I'll be teaching a pinhole class, constructing > cameras from Quaker oatmeal > canisters.

Re: [pinhole-discussion] Cutting oatmeal box
Any power tool will shred the cardboard.

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.

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). 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
[pinhole-discussion] Cutting oatmeal box
I'll be teaching a pinhole class, constructing cameras from Quaker oatmeal canisters. I'd like to avoid using knives to cut the opening for the pinhole. I've seen suggestions for using a Dremel drill, which I don't own. A trip to my local hardware store wasn't helpful; the tool guy said a Dremel wouldn't cut a clean hole in cardboard and pointed out the cost of the drill. Is a Dremel the best alternative to a knife? If so, what Dremel bit should I buy for this job? Thanks, Chris _ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp.
