Becky - This is correct. You will want to match your pinhole size to the focal length of your camera. I find it easiest to make 10-12 at the same time. I do this because it is extremely difficult to get the exact size you are looking for. By making a bunch of them, when you make your camera, you will probably have a pinhole that is sized nicely for your camera.

I'm considering my first try at it by re doing a camera that i <br>already have to get the feel of it. ( I do like the ideas here of making <br>them out of various cardboard containers, and will try that after I get <br>comfortable with the overall technique)<br>My question is in regards to the post below here.....<br>If I drill my own pinhole and want the smallest possible hole with the <br>number 15 needle, do I understand correctly to just get the point <br>through, then sand the rough edge and that's the end of it? If the <br>needle goes farther, then the shaft makes a much larger opening?<br>Thanks in advance!<br><br><br>Chrome Dome wrote:<br>> <br>> As mentioned earlier most stores with fabric departments sell quilting needles. They come on a card with a plastic 2.5" diameter dial type dispenser that has compartments containing needle sizes 4-12 but for some reason excludes #11. <br>> <br>> Hobby/craft stores sell the above packs too, but for even smaller needles you need to look in the craft section for beading needles. Hobby Lobby (another national chain - closed on Sundays) sell Beadsmith cards of 4 needles. One card contains sizes 10-13. Their smallest needle is size 15 which measures .0085" at the point. The shaft is .0095". At our store and I guess nationally these needles are not with the "seed beads" but in the next isle with the beading accessories as thread and wire.<br>> <br>> I use a jewelers (machinests) pin vise to drill with needles and the small drills that Guillermo discussed. My pin vise is appx 4" long and slightly larger than the diameter of a pencil. At either end is a one inch long threaded collett which tightens or loosens the oriface. The range of the smaller end is appx 1/16" to zero. The larger end 1/16" to 1/8".<br>> <br>> Warning these needles and drills are extremely fragile!!! Chuch them up so that only 1mm appx is exposed! Twist the pin vise with your thumb and index finger to drill. I place the metal on top of a white art eraser as a backing to drill into.<br>> <br>> Mike Atwell<br>> <br>> <br>> <br>> ____________________________________________________________<br>> Get advanced SPAM filtering on Webmail or POP Mail ...
