leupold Question

Give Cecil Tucker a call. I think that he will tell you that the erector tube pivot joint in these scopes has lateral clearance sufficient to allow several thousandths of movement, which is why his conversions have a groove cut in one of the mating surfaces for an O ring that is compressed when the parts are assembled.

The reticle slips inside a fit, it has about .0005 clearance. It has a small key that "clocks" it in the correct position so that the cross hairs are in alignment up and down.

The reticle nut holds the reticle against the wave spring, that compresses the erector tube against a spherical shoulder machined inside the scope.

I am not sure if there is a problem with the reticle actually "shifting" inside the scope. It actually is tightened against a shoulder. I would say this is not a sourse of any problems.

Boyd. Cecil's conversion places the small o-ring on the OD of the sphericle surface that seats against the shoulder that is machined in the scope tube. It is not actually machined into any originol mating surface that is designed in the scope. What it does is help stabilize the erctor tube in the radial plain, as the register surface on the gimble joint is quite small. ..........jackie

Jackie,
I bow to your experience, but I do believe that Cecil told me a larger number. On the other hand, that was a long time ago, and my memory is far from perfect. Your details are always of interest. I wish that I lived closer, and could talk you into letting me shoot a photo essay on disassembling and freezing a Leupold. I think that it would be popular. Where do you think that movement takes place? You surely have done a lot of interesting stuff on these scopes.

We are speaking of two different fits. The erector tube's major diameter that Cecil installs the o-ring on does indeed have much more clearance, possibly .003 or so. The Reticle fits into an entirely different spot.

The originol question was concerning the reticle, which in theory, is locked into place when the reticle retainer nut isfirmly secured...........jackie
 
I read the other thread...got it. One bad assumption led me astray. There are not too many that have taken them apart.
