Step 3 - Drilling holes in the kiln floor
• Locate and mark the center of the kiln floor.
• Use Diagram #1 as a guide to drill the appropriate hole(s) in the
kiln floor. Important: The holes in the floor must fit within a 1
1/2" diameter circle at the center of the floor.
• Use an electric drill with the correct size bit. Drill slowly, keeping
the drill straight. Precision and care are important to avoid drill-
ing an oversize hole or chipping of the floor underside.
Step 4 - Drilling holes in the kiln lid
• Measure the thickness of the kiln sidewall fire brick and add 1" to
this measurement. This will be the distance from the outside edge
of the kiln that your holes will be drilled.
• Space the holes evenly around the kiln lid but no closer to the
edge than the distance above. Because the holes introduce room
temperature air into your kiln, they must not be clustered togeth-
er or directly above the thermocouple. Refer to diagram #2 for
proper hole location and spacing.
• Drill the holes in the lid using the same method as used for the
floor.
• Vacuum out any brick dust from inside your kiln caused during the drilling.
