Proper solar filters for cameras, telescopes and binoculars tend to a bit pricey. But disposable solar observation (eclipse) glasses are quite cheap.
What are the pros and cons of rigging up a single ocular of such glasses as a cheap solar filter? I am thinking of rigging one up over a hole cut in a cardboard hood that I could then mount on a lens. Certainly these filters are good enough quality to protect my eyes. Will they also protect my camera's sensor?

The glass that fits in a welding helmet might do the trick as well. You'll have to create a custom white balance setting for use with the filter.

I bought as you suggested a #14 welders glass size 41/2 x 51/2 my cokin filter holder needs 4inches wide so I took it to a glass cutter and guess what happened it broke had something to do with it being tempered but it broke in such a way that I was able to super glue a piece back on and it fit nicely in my holder so I took it out side pointed it at the sun and i could see it I just don't have a lens that is long enough to see it closer but the welders glass works if you can find it I got lucky cost four bucks need another way to cut it don't know if this helps

Caution: Plastic filters, fogged film, are not good for you or your camera. Eclipse takes place late 5/20/12 and can be seen in NM, AZ and CA. Not sure about other places. InfraRed rays that are not filtered out can do eye damage. An Arc welder's filter #12 to #14 will work well. Do not use a gas welders filter.
Orion Optic sells a solar filter that works very well, I use their filter almost everyday to photograph sunspots. I use a 300mm AF VR type lens on my D7000 set at M at F11, 250 sec.
I use Adobe Photoshop Elements 7 to make any exposure correction/color correction. I use layers to place date and time on the printed image. This is a nice way to keep a record.
