That great! .... Except you forgot the $600 CAD software, $300 used computer, $200 usable CRT and the $150 vernier hight gauge. Lets see, that's about $1250 not counting the camera. http://bbs.homeshopmachinist.net//frown.gif

I'm too cheap to spend that much. http://bbs.homeshopmachinist.net//biggrin.gif

Good idea.

Not to be smart, but how do you center the webcam inside of a socket to fit inside a spindle ? How can you check it ?

If you could fine tune the grid and mount it so the camera is a fixed distance from a table you'd have one fine optical comparator. I think that it would work if you could generate a grid that had accurate graduations. Would that work? I just saw it and got to thinking...

Boy John, you are a clever fellow!

It really isn't important to accurately position the camera in the spindle. As you swing the camera 180 degrees you will visually see the center of rotation. The more focused the camera is the finer the centering. Since these cameras are available for as cheap as $25 and most of us already have extra computers I think it is one of the greatest ideas I've heard of in a long time.

Thanks John, you brilliant kilt lifter you!
