Bonding would be tough
If the edges are exposed, it is hard to hide air gaps.
If you have no air gaps, the bonding needs be completed in a vacuum to prevent fogging (moisture drops).
This is assumming you arent going to try to do a complete surface bond. I can't imagine how to prevent bubbles/dust getting trapped.
CNC is not too bad for unskilled "curve" cuts in glass. (assuming you are CNC adept). Use the outer edges of you glass for edge pressure testing. (how much material at what feed rate with how much coolant for your tools...)
I would try cheaper thinner glass for initial tests. Glass is a crystalline structure. It chips and fissures if stressed wrong.
If part is too big, can you machine halves or thirds? |
