                                                                                   for the jigsaw to run against during the long cuts. Drill an entry
                                                                                   hole for the jig saw blade and ease up against the guide to
                                                                                   make a clean and straight cut. You can freehand jigsaw the
                                                                                   keys but it won’t be as neat a job or have as straight a line.


                                                                                   8. The longer keys can be sawn to length again using a
                                                                                   guide. A right angle guide is clamped and keeps the saw
                                                                                   straight. The two shorter keys have to be sawn freehand.
                                                                                   The endgrain on these will need to be straightened up with
                                                                                   a file. Or do as I now do and use a plunge router to
                                                                                   dimension the keys to length.


                                                                                   9. I sand the top now to 180 grit. The ends and side can have
                                                                                   their final sand after the tuning. These drums always need
                                                                                   rubber feet to sound well, so for the tuning process I fit rubber
                                                                                   feet to the base.


                                                                                   10. Establish a key you are happy with the sound of and

                                                                                   the pitch. It is a slow process sounding a note, drilling and
                                                              11                   repeating. It took me hours to tune my first drum.

                                                                                   11. Remove the rubber feet fitted for tuning and ensure the

                                                                                   careful you were when initially gluing them these areas won’t
