Improving the 3D viewing for a Sony HMZ T1 - PART ONE
Posted: Fri Jun 09, 2017 1:42 am
Hi,
I will be writing a multi-part thread describing improvements to the viewing of 3D images with the Sony HMZ T1.
These mods involve disassembly, removing parts and, permanently reconfiguring and altering the appearance of the headset.
This is a work in progress and may be revised at any time.
A number of steps will be described to achieve this.
They will be:
Step One - Bringing the eyepieces into the correct lateral position for the user viewing 3D images
This will entail the classic 'gear wheel mod' and the additional 'friction clamping mod'.
Step Two - Bringing the viewers eye closer to the viewing lenses.
This will entail modifying the front bulkhead of the headset to bring the users face forward into the correct eye box position.
Step Three - Bringing the correct depth of field for 3D viewing by use of modified prescription glasses.
This will require one pair of spectacles to be worn between the viewer and headset.
None of the modifications is necessarily related to ergonomics or comfort. That can be sorted out afterward.
It is the optical conformity with the user that is essential and will be exclusively looked at here.
STEP ONE Continued
The gear wheel mod removes the pinion wheel connecting the corresponding gear racks on the two eyepieces, so the eyepieces can be moved independently for optimum lateral eye box positioning.
The following online SONY HMZ T1 disassembly and gear wheel mod guide is recommended for viewing.

This is the video I first used when performing the gear wheel mod.
Following the gear wheel mod comes the friction clamping mod.
The friction clamping mod removes the cogging from the lateral spacing of the eyepieces and replaces it with an infinitely adjustable friction clamped spacing mechanism.
The friction clamping mod involves removing the two steel cantilever spring posts above the two sliding white plastic racks, then unscrewing and flipping upside down the white plastic racks, and then screwing the white plastic racks back in place.
By adjusting the overall tension of the four clamping screws on the sliding eyepiece rack, the level of clamping friction can be adjusted for each eyepiece.
The sliding tension of the eyepieces must be set before putting the casing back together, as the friction level cannot be adjusted outside of the casing.
The following photos show what I did to my Sony HMZ T1 in order to perform the gear wheel mod and friction clamping mod.
PART TWO - modifying the front bulkhead of the headset - will be posted in another thread and will be linked from here.
Thanks.
