I'm getting close... Got everything trimmed around the edges, then realized I had to come up with a way to trim the laminate around the routered port recess. I had to find something with an 1/8" bearing... So I finally found a flute-style trimmer bit and ground it down to 1/8". Grinding carbide is not fun... where are all the cheap bits when you need them?

Finally got it cleaned up, then I masked it off and sprayed the inside so I wouldn't see any wood around the port.

After that I got the lip leftover from the trimmer bit with the sander, so I can lay the black laminate flush over it.

Well I went to home depot today and the black laminate that I originally 2'x2' was actually 2'x4' [just what I needed], so that saved me about 14 bucks, and allowed me to get the contact cement with it for under 20 bucks.

I cut it in half (total *****) and routed out the hole for the driver for the bottom piece. I figure I'd do the bottom first in case I **** up. I was worried about getting it stuck in the wrong place, not having enough glue, having too much resulting in it gooshing out th sides, etc. Well I did it and it worked out perfectly. Perfectly lined up, no goosh. And it's really on there.... not going anywhere.

Also got the holes on the precision port countersunk so there wont be any ugly screws sticking out on the flush port mouth.

I think I may be done this weekend... yay. Actually....wait... no... I still have to get the binding posts in from Madisound.

I wonder if I should line the walls with sheet poly? Maybe egg crate? It's not going to be one of those test and retest situations... once the driver's in it's in. :p

 
I tried lining mine with polyfil and almost lost 2 dbs from 25 hertz and up.. and didn't gain anything below it. I built mine as efficient as possible with all the known spl tricks but it still sounds very good, I dunno if anything I did to mine raised thd somehow but I really don't care it sounds awesome either way.

 
I would say put a little poly in for deadening but not too much.

Putting too much will make the driver cavity act bigger than it actually is... //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Sanding edge of bottom laminate

Tape/glue/trim/sand top laminate

Pilot holes for port mouth

Glue/assemble/install port

Floor spikes

Binding posts

Transportation (Going to ****)

Wiring/Installation

Eviction

 
With the work I did tonight, I'm pretty much done and ready to bring it to my apartment. I trimmed the top laminate, glued up the port and screwed it down (its actually much stiffer in place than I thought it would be), and drilled the holes for the binding posts.Then I cleaned out the box (which took forever) to keep the coil clean.
