Workshop Panorama
Slots in the bracket allow one to adjust swivel point and lens nodal point for the camera and lens to eliminate parallax artifacts when sweeping for the stitched panorama.
A short length of pipe was capped by welding a disk to the top and then turned down and trued in the lathe. It was then knurled to provide grip when adjusting the bolt that secures the nodal bracket to the rotator.
The cap was then drilled prior to cutting 1/4 -20 threads.
The lathe and a live center hold the workpiece and tap true while it is hand threaded. Hand pressure on the tailstock wheel serves to keep the center properly tensioned while threading.
Truing the disk that has been welded to the bearing spindle.
Using a spotting drill to make a starting hole for the drill.
Again, tapping the spindle disk.
The excess weld that holds the disk to the spindle is being dressed off.
Finished parts ready for assembly.
You can see the slots that allow the camera to be slid in order to eliminate parallax. The bottom screw and slot center the middle of the lens on the rotation point. The pivot screw allows the arm to swing in an arc that remains true when pointing the camera upwards or downwards.
A 21 picture composite of the east wall of my workshop. This photo was stitched from 3 sweeps. One pointing slightly up, one horizontal, and one pointing slightly down.
