I like the ProBox System. One of the reasons I keep asking questions about it is to see what other people are doing. I’ve tried the 3M 90…too Strong , been thinking about cheaper stuff like Herb says…I went ahead and bought another can of the Super 77 because it’s always worked good for me…
Let’s hear more about the router bit. I use an old fashion router. Very powerful ,takes two hands. Move slow for best results. I have always set my bit at 1" just like GreenLight says. The last two installs have not cut out so clean. I figured it’s either the bearing or the depth of the cut…So I started the thread…Looks like my router bit is fine. I’m doing a quad sometime this week. I’m going to set my depth at just a hair under 1" and go from there.
Tape between the board and the jig. Yes for retro fits. Otherwise I’m going to power sand the whole thing so I don’t tape.
The key to a successful route is to make sure that the top of the actual cutter blade on the bit is a 1/32" above the bottom of the jig so that the cutter is not below the bottom glass. The exact measurement for the amount of cutter exposed is 0.719" or 23/32". This translates to an actual measurement of 15/16" from the base of the router to the tip of the router bit as the jig is 7/32" thick.
When it is setup this way the top of the bearing will be slightly above the top of the jig, but the thing to care about is the depth of the route and that you get a clean cut at the bottom layer of glass.
