Build A Pair of Stereo Speakers

Step 10 Preparing The Back Panel

To finish the back panel all we have to do is:

Drill holes
to screw it down once everything is done. Drill holes large enough for the screw to slip in the particle board then drill corresponding holes in the 1" X 1" thin enough grip the screw.

Construct and install the terminals
It is possible to buy finished terminals then all you would have to do is make a hole in the back panel to mount it. But since they are so easy to make, might as well just make it.

The first thing to do is drill a large hole (minimum 2 inches in diameter) into the back panel. An easy way to do this is with a circular sawing drill bit (see pictures). Next we need 2, 3" by 3" or more of a solid, flat, firm piece of plastic, acrylic or metal etc. Drill two holes in each piece for mounting the electrical terminals. Then glue the piece to the back of the hole and make sure it is airtight. I used epoxy but silicone or other glues will work just fine.

There you have it, the back panel is finished. If you want you can put a final layer of paint on it but since its at the back, its hardly seen.
