I thought I would show how I go about making a glass door for my cabinets pieces. Instead of using a cope and stick router bit set, I opt for a better (in my opinion) offset mortise and tenon joint. It takes a bit of time to figure out at first but it really isn't difficult and makes a super strong door. When working with glass I want all the strength I can get. I have done it with the router version before and it works fine but I have also broken the the joint by accidentally dropping it on the floor. Granted the profile on those bits give a nice look, but to me they also look like kitchen cabinet doors made in a factory. With a mortised joint it is pretty much going to look like furniture. If you put a square peg through it, I don't ever see it coming apart and it will set the door in a more furniture realm than kitchen cabinets.
