While waiting for a part and other shop work to finish I decided to remove the cataract safety glass. On this one there was not a really hot afternoon and when a front moved through the temp droped and sky became overcast. I heared the glass "TICK" and that was it.
I have removed most of the pieces and I'm down to the last pieces near the center. The PVA is thinner at the center and there is less 'give'. I'm using single edge razor blades as shims at this point and the going is painfully slow.
I'm hesitant to use a hair dryer to help heat it up as most of the face of the CRT is now exposed. There are a few observations I've made.
- Separations showing as an arc break off quite soon
- Separations as showing like fingers result as larger chunks
- The closer to the center the more dificult to do anything with the glass.
- This tube checks really good and had a great picture and the next time I do a cataract removal they'l have to be much worse!
I have a spare clear glass from another set to replace it with.
Any advise would be great. I'm sure that I'm not the first to have to overcome this situation.
