That turned out nice, are you going to put corner protectors on it? Seems like that would be a good idea in the long run.
I wish I was handy, but a woodworker I'm not.
I do have a sorta DIY 2x12 cab myself, but I bought it from a guy who had already put the speakers in, so all I had to do was wire it up. Basically it's just an old Crate combo amp that somebody took the amp out of. After I wired it up I did spray paint the faceplate black so it wouldn't have distracting markings on it.
It doesn't look very sharp but it's got 2 Celestion V-12 60's in it, I only had to do some minimal work, and I bought it for only $90.
Here's a lousy pic of it set on end as a "quarter stack" with my Sovtek "Tube Midget" head:
It's horizontal here, sorta buried behind the guitars in this pic, being paired with my '60's Sunn 200S head:
Here's some pics before the speakers went in:
Here's what's inside:
