Step 4: Drilling
Now that you've cut your PVC Piping with either a chop saw or pipe slicer, you must accurately Drill an 8mm hole on the absolute center of cuts (2.) and cuts (4.)
To do so one must utilize a Jig that is suited for a 1 inch pipe.
Get a 1x7x4" piece of wood, then cut two 3x1"x 4"s and lay them onto the 1x7 and sandwich Some pvc in between and screw it flush and firmly.
Next measure and mark the center between the two and drill. If its not near-perfect make another-one.
Take another screw 6 inches long and screw like your going to go into the pipe, this will be the clamp to keep your pvc in place.
So if the jigs length is 4" inches then mark 2 inches from any side of the center of the Cut PVC.
Clamp and tap by using the hole in the jig to guide the drill into the pvc.
Funk yeah! your holes are perfect every time!!!
Remember! Dont glue till i say so!!
