12" REFLECTOR - Work has begun.

My trusty ole lightbridge is getting a complete makeover.
It will become a dedicated astro photography platform (I hope).

Am working in conjunction with an engineer for structural design issues.

Having said that, if I have overlooked the bleedingly obvious then please let me know!

1: Removed the large support bearings - not a DOB anymore.
2: Check weight - 19.2kg
3: Total weight must be below 20kg (mount limit)
4: Removed 500 grams from bottom ring beam (30mm holesaw).
5: Removed 500 grams from top tube (60mm holesaw).
6: Installed camera (the camera will face downwards) and re weighed and found balance point .

Still to go:
7: Weld on dovetail mount bracket
8: Weld on structural ribbing on bottom tube.
9: Re weigh and calculate how much weight reduction is needed on bottom tube.
10: Attack the bottom tube with 60mm holesaw.
11: Mount guide camera and finder.
