Well I did the cataract removal today(well it was today before it hit midnight).
The tube is a Silver-Glo rebuild(I assume). The PVA was really weird...The outside edge was calcified for lack of a better word, and the center stuck to the face of the tube like Zenith type PVA.
The sun was a tad patchy, and between it 16 cloths pins as wedges around the perimeter and a hair drier it barely wanted to come unglued around the edge. I went a bit far with the wedges and the safety glass cracked. I ended up chipping off the safety glass which was not fun.
All in all aside from the loss of the safety glass it seems to have turned out well.
Tomorrow I'll finish remounting it and resume work on the electronics.
