Box build log for a SA-12

[The enD]

Hi from Bulgaria, everyone. Here I'll be posting my build log of a box I am working on. This is going to be my first properly done box. First time using plywood, wood glue, clamps and any sort of design and calculations. Last one was done with particle board, silicone and screws.

Let's talk about the box. It is going to be 1.74 cub ft net for a 12" SA-12 , the used material is poplar plywood, kerfed port tuned to 32hz, flushed driver, painted port and around the driver in white, wrapped in carpet, bolt terminals.

The design was done by bromo and excellent is the least I can say about it. He did all I asked about the box in a pretty fast time considering it is not an easy job. He is the man!

And let's get on with the pictures, shall we?

Example of Bromos work. He gave me all the dimensions and a good explanation about how I should proceed with the kerfing.

Got wood?

Doing some work.

Playing with the macro. Forgot to turn on the flash. :/

Cleaning factory cuts.

Part of the puzzle done. I think I need to cut two more pieces and then it's glue time.

Doing some work. Glued bottom and back.

First time kerfing, so did some experiments before working on the actual piece.

Now I am going to glue the sides and cut the kerf.

These were made by my father when working with bigger project like whole doors and windows. But I ended up not using them.

I need more clamps.

Glued and clamped. My hand kinda hurt a lil but it's for good, very tight bond.

Right before cleaning the excess glue.

Playing with kerfing. There is a critical point where the wood bends or breaks.

Looks good to me. Now I have to do the same thing to the big piece.

First two pieces glued.

Now lets fire this bad boy up. Mega Sander lol

That's the side which will be a part of the port. It has to be smooth for the paint. Before/After picture. Very soft.

The whole piece is covered with glue which is very important for a strong bond.

Clamping again.

And now the kerfing.

Marking where I should cut.

AND NOW EPIC FAIL....................................................................

FUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU

That is it for today. I'll just make a new piece tomorrow.

Sides glued.

New piece sanded and drawn again. This time I used a piece of wood and a clamp to attach it to the baffle. That way I can hold the saw against it and make straight line. The first time I hold it without support and the lines were not the best.

Perfect. That extra line is for the 11th channel, but I didn't cut it.

YES!

Dry fit. It needs a little more work for a perfect 1/4 circle.

There were some little crack, but nothing to make it actually break. Minor sanding and it will be perfect.

Beautiful. I'm relieved considering my first failed attempt.

I don't know much about taking pictures.

Gluing...

Glued. Some minor sanding on the right too.

Baffle.

And the flushing panel.

The bigger circle is not sanded yet. Needs a little bit more work on it.

I had to put a 12 I got to see how it looks. It's good.

=) =)

Someone took my camera, so I'll post these not so good phone pictures

The 45 at the end of the port.

Gluing it. 4 screws in the back. One clamp on top and note the big scrap piece of wood I made for a minute. It has a rectangle cut in it so you can put it in the corners of the box. =)

Bought some t-nuts. I'll be using the old hex head screws I had.

End of the port. Routed on both sides. Then went through the belt sander.

Gluing the baffle.

6 clamps and 4 screws. That's enough right?

you know...

that one kerf wont do much unless you kerf then inside opening of the port too.
