Can this be done? Will the aperture work correctly?

Yup. Standard operating procedure. Make sure the lens is set to Manual and you're all set.

Ive got a takumar 200mm and a tamron 400mm and they work fine on the K3. The only thing is that the takumar won't focus on infinity so I might have to get that lens adjusted by an expert oneday.

I assume you meant automatic. Is there some sort of attachment so that you can set the aperture manually

My M42 lenses have a switch near the base and markings for Manual (M) and Automatic (A). Most M42 lenses have this but if they're the automatic kind w/ a pin, you need to disable that.

NOPE MANUAL.

In the still camera the lens is stopped down by a pin in the back just before the shot, this will not work for movies, so the lens must be run on manual so it is stopped down all the time. A few of the lenes don't have the manual setting so they must either be modified or traded.

Noote that the lenses for the Sportmatic f have the switch but it will not go into manual Unless a small pin near the threads is pressed in. I am not sure if the K-3 will press this pin. You may have to press it, and set the lens on manual beofre mounting it on the camera.
