Dieselpunk Stereophonic Amplifier

Step 2 Make: the Box

Place the speakers within the box. Make sure there is enough room for the amp. Trace out a border for the speaker opening. The opening must be larger then the speakers. With a Dremel tool cut out the opening in the box. The Dremel tool leaves a clean cut compared to tin snips. Grind down the edges of the cut so that it is even.

Using the 1/16 inch brass rod, form an edge around the speaker hole. To do this, gently bend the brass wire around a cylinder-shaped object to get a smooth radius around the corners. It took two pieces of wire to make it around the full circumference of the speaker hole.

Next, solder the brass rod to the box. It helps to hold the rod in place with some clothes pins while soldering. Using solder flux helps too.

Finish the hole by filing and sanding the edges.

To give the box a more industrial look, drill holes into the handle. Measure then centerpunch for 5 evenly spaced holes. Use a stepped drill bit to incrementally enlarge the holes. It it easier to keep the holes aligned by slowly enlarging them.
