8. Glue up the non-drilled v-cutout to one of the other 8" boards you cut in step one. Glue them face-to-face. OK, you could have done this as step 4 but then I couldn't have called this part called "glue and screw". Plus, now is your chance to grab a beer, preferably homemade. You are going to have to wait for the glue to dry before finishing the project. Go read a "Make" magazine! Or find some other way to occupy yourself. Check your glue bottle instructions for drying times. Usually 30 min-1 hour. For those of you who are feeling cynical, I don't have any personal affiliation with "Make" magazine but that's what I did at this point.
9. Screw your glass cutter onto the second v-shaped board using your clamps. Use your wine bottle to check that it will make contact with the cutter when the jig is put together.
