Aperatures that might work well for pinholes can be found here.
I would recommend the platinum aperatures. The gold foil ones would be too fragile to handle in a camera situation.

Marlin P. Jones & Assoc. Inc.
Has surplus video cameras and pinhole video cameras real cheap! [less than $100]

Black foam core, Exacto knives, etc. can be had at art supply stores. Black tape from camera stores [$16/roll] or art supply stores [$5/roll].

Hobby supplies, check out:

Micro-Mark hobby supplies, small tools, etc.

finger drills
Rogers Drill bit set, #61-80

Be careful with Micro-Mark. Their stuff looks good on paper, but I was not always satisfied with the product delivered. Definitely do not order large quantities till you have checked out the product in question.

Orchard Supply Hardware and Home Depot both have shim stock. Get brass at 1-2 thousandths of an inch. [2 is easier to work with for the beginner, 1 will give a better hole with practice]. OSH has decided recently NOT to carry shim material, but ask, they may still have some left.

Another source of thin metal is soft drink cans, approximately 0.004" thick. Has the advantage of always being around.

4x5 and 8x10 Cameras

Check out Bender Photographic. They have 4x5 and 8x10 kits for $279 and $379 respectively. I have made the 4x5 and it would work great for pinhole and zoneplate work. [so would the 8x10 I suspect]. As some single focal length pinhole cameras can cost as much, why not put together a pinhole camera with interchangable "lenses"? They also sell film holders for above.

They also have a multi-focal length pinhole camera kit for only $69.95. This is not plywood, but real hardwood. Looks like an excellent camera kit.

Freestyle Cameras has a pinhole camera page also.

Do not overlook "hot glue". VERY fast way of assembling 4x5 and smaller cameras. Probably not strong enough for the larger, 5x7 and above formats without thought to internal structural supports.
