You'll want to put the bowl in the middle of that navy blue stripe (2nd stripe from the bottom), so to make a hole, you will need a drill and drill bit. You'll have to drill at a slight angle to get it to fit right, so you'll need a steady hand or drill press.

If you make a carb hole, there is no need to make the bowl a slide then. Either the bowl is a slide and you use that to clear the bong, or you set the bowl perm. in place and drill a small carb hole.

For the carb hole, I would drill a small hole straight in, in the middle of the yellow stripe towards the top.
