It’s at this point, we need a drum shell of some kind. Here’s what I came up with. We will use a 9″ dia. heavy duty cake pan. (see parts list). They’re cheap and they are just about the right size. Using the template (x4Ld.pdf), mark all holes with a punch and or nail. It’s a good idea to put a couple of pieces of tape one the template to hold it down while marking the holes. Once the holes are marked, remove the template and drill all holes. Be sure to refer to the template for the size of each hole. That’s pretty much it for the cake pans.
Next, we want to make the foam sensor coupling base plate.
Tools needed for this section:
– hack saw
– drill with 3/8? drill bit
– hole punch or nail
– bench vise
First cut out the Sensor Plate template (x4Lc.pdf). Using the template, place it on the 1″ x 1/8″ aluminum flat bar. Mark the length of the plate with your pencil and place it the bench vise. Carefully cut the plate to length with the hack saw. Once, you lightly file the cutting edge, tape the template back on the plate and mark the holes.
Remove the template and place the plate in the vise as shown
Now just drill your 3/8″ dia. holes.
You may need to de-burr the holes once you are done drilling.
In the next post, we will put in the 1/4″ input jack, line-up the pan with the base and fasten the pan down.
