Optical Centering of a Scope

Following discussions with Dave I've been thinking about the simplest way of creating a holder for a scope that would allow it to be rotated without damage but ensure that it acted in a predictable and reliable manner.

It struck me that a solution might be really quite simple but being cack-handed I'd not be the best person to prove it.

The solution (if it be one) is as follows: -

Take a pair of mounts (tall would be best) and stick felt both to the inner surfaces and the outer surfaces where they may contact the scope to avoid possible damage to the body of the scope.

Mount the mounts on a rail that is, in turn, attached to a piece of wood that may be clamped in a vice or workmate. The rail allows the mounts to be moved to suit the scope being centred.

Space the mounts so that when the scope is placed on the lower part of the mounts it can't move backwards or forwards.

Lightly attach the upper mounts so that the scope is secure but may be rotated in the mounts.

The felt provides gentle grip and there is no damage to the scope.

The scope may then be rotated and the appropriate turret adjusted so that the cross hairs are on the correct and same point. This may then be repeated for the other turret.

The result should be that the scope may be rotated and the cross hairs remain absolutely constant on the chosen index point at all times. Thus, the scope become perfectly optically centred.

If this is a simple and practical solution perhaps one can be fabricated for the club and perhaps such a device could be sold by the club such that some profits may go to Help for Heroes. There are very many gun shops, clubs and enthusiasts to whom such a device may be sold.

A small cardboard box,big enough so that the edges (of the width of the box) fit inside the clamping area of the scopes where the 'normal'clamps are positioned.
Cut two 45 degree notches on each edge and place the scope body across them.
The scope can then be rotated and adjustments made so that the time will arrive when 'no' deviation will occure when the scope is rotated around its axis.
Ensure sufficient clearance is availabe on the box, and if it moves put weights in the bottom of the box to stop it.
Cheap,easily available (zero range shot gun boxes)and when finished goes in compost ''to help the environment' which is important. Rolling Eyes
