2-inch Gimbal Mount less Lens Holder, less Bracket

Description

This is a Burleigh gimbal mount for optics or mirrors of 2 inches diameter. It is a true gimbal – both the azimuth and elevation axes are co-planar with the front surface of the mirror cell. The mounts are exquisitely made from three basic castings – two for each of the gimbal planes and one for the supporting plate. There are three basic subassemblies to the mounts. The gimbal mount with the micrometer spindles; the removable optic carrier mount; and the angle support plate. This mount lacks the optic carrier and the angle support plate.

This version is a bit earlier – the micrometer spindles lack the large plastic adjustment rings for increased setting sensitivity. Each axis has internal springs to keep the gimbal plates in contact with the micrometer spindles, and in addition, a spring-loaded plunger to augment stability. The position of the plunger can easily be changed so it will be effective in the range of motion required.

The removable optic carrier is missing from this mount – currently there is a clear bore of 2.255 inches diameter. One could easily fabricate a mirror holder to fit the bore.

Dimensions:

� Gimbal support plate – 4 inches wide, 4.75 inches tall (0.500 inches thick)
� Optic axis height = 2 inches
� Range of motion (azimuth and elevation) – approximately plus or minus 2 degrees
� Modified Starrett 263 micrometers with large thimble rings
� Overall depth with micrometers – 4 inches
� Minimum / Maximum mirror thickness – 0.25 / 0.60 inches.

Condition of everything is superb. The mounts have been rebuilt and the micrometer spindles cleaned and relubricated. This version of the mount is cast of light aluminum alloy as opposed to steel. Please note that the elevation spring plunger missing in the photos has been replaced!
