Shell Drilling Layout Mat

The Sparedrum Drum Drilling Layout helps to trace easily on the shells the drilling points where you will insert the lugs, snare throw-off, butt-end, air vents, etc...

For drum shells from 6" to 26"

How to use :

• On a rigid and flat surface, position the layout mat.
• Place the shell on the corresponding diameter ring -- the black line should be slightly visible. This will help to ensure that the shell is correctly centered.
• Hold the shell in position (it must not move.)
• Use a square to draw lines with a right angle on each colored visual mark that matches your desired lug count.
• Draw marks where your snare throw-off and butt-end will be positioned using the graph paper sides.
• Double-check that the lines you drew are correct using your square.
• Once all the vertical lines are traced, you need to mark horizontal lines with your square to finalize the drilling points according to the dimensions of your hardware

Our advice:

• Before drilling, check your work several times.
• Check that you are using the right drills (right diameter, adapted to the shell material)
• Measure and check carefully the dimensions and center-to-center dimensions of the hardware you want to install
