I made 2 slices with the first one being 2" thick and the remaining piece can cut out of a piece of 1" material.
Look Ma No Face!
This was a big file with all the textures etc. It took the router 7 hours to cut this piece. ( this is when you hope the power dosen't go out !)
This similar type of system (without the bag) is what is used to hold the parts on the router table when it's cuttting.
The other advantage to this type of clamping is thatthe Gorilla Glue expands as it cures and can really make a mess, The bag that holds the parts in place contains the expansion of the glue and makes for easier clean up of the glue line.
