Step 6Mounting the Woofer and Tweeter

Mounting the Woofer and Tweeter
In this half of the tutorial you might find some of my solutions to things a little temporary and I am positive that there are better ways.  I mounted everything in the salad bowls in the simplest fashion possible.

For the next few steps the tools you'll need, give or take, are:

 - A Pencil
 - Phillips Head Screwdriver
 - A 1/16th Drill bit
 - Double Stick Tape (one of those temporary solutions)
 - Gaffers Tape (Really one of those temporary solutions)
 - Small wood screws:  The thickness of the bowl is a 1/4 inch so you will want some pretty short wood screws.  Get at least 20.  I used slightly thicker wood screws for the woofer and tweeter and thinner wood screws for the circuitry.  The thinner wood screws were a bit longer because they go through the nylon spacers you'll see below.  I apologize for my lack of specifics when it comes to these screws.  You should use your own judgment when you get the salad bowls and see for yourself.

*I tended to over-buy the wood screws in various lengths in order to guarantee that I had enough to finish for the night

 - Nylon washers:  These are meant for the wood screws.  I got nylon because of the circuit boards.  it really doesn't matter what they're made of as long as they don't make contact with any of the components or pads on the circuit boards.  With my time constraints for finishing I just felt better using nylon.

-Nylon Spacers:  These are for inbetween the circuit boards and the interior of the bowl.


The first step was to screw the woofer and the tweeter into position.  Start by lining up the woofer over the 4inch hole and putting some firm pressure down to bend the metal where the screws go, to form to the curved surface of the salad bowl.  While holding it in place flip the salad bowl over to see how it's lined up.  If it's good, flip it back and mark the locations with a pencil.

I started by drilling four pilot holes with the 1/16th drill bit where I had marked with the pencil.  (See Picture)  Then I placed the woofer back into position and flipped and checked again.  I used the phillips head screwdriver and the thicker wood screws with the nylon washers to attach it.  

(The nylon washers were used because at the time I wasn't sure if my screws were going to go completely through the bowl.  The length of the screws that I had were awfully close to the same thickness of the bowl.)

Once the woofer was secured into position I repeated the process with the tweeter.
