I cut some
plastic from the leftover Fleet Farm bucket and riveted together . This
will be a 7" diameter x 1 1/2" drum. You can make just about any size
you like.
I cut a slit down one side of some plastic
tubing and pushed it over the top edge so it wouldn't have such a sharp
edge for the mesh head.
I used a router and a homemade circle jig to cut the 3/4" oak Veneer fiber board paneling
into hoops. (Or
you can buy one of these) I cut the inside diameter of the top hoops
big enough so they will just fit over the top of the bucket.
On the bottom side of the top hoop
I used a table router to cut a 1/4" deep groove wide enough for the
screen mesh head.
Took some copper tubing and formed it to fit the 1/4" groove and cut to
size.
Sewed on some window screen. The mesh screen head rim now fits perfectly
in the groove.
Used a router to cut a circle for the bottom and an 1/8" deep groove for
the bucket to fit down into.
Placed top hoop over the bottom circle and drilled 1/4" holes through
the top hoop and bottom circle at the same time.
Increased the size of the holes in the bottom circle to 11/32" to fit
the 1/4" threaded insert.
Now we can start putting it togeather.
Added the Oak L rod Clamp. Arrows show where I
drilled holes that line up with the holes in the top hoop and bottom
circle.
Installed the 1/4" jack and piezo Sensor. Used a couple layers of 3-M
double sided foam tape under the peizo to get the foam block about 1/8"
above the rim.
Tightened down the mesh head with 2 1/2" x 1/4" screws.
