I recently decided to do a practice enclosure (kerfing practice for the most part) before I build the enclosure for my next build.
Now to do a kerf, you need to remove wood to make the wood bend. I used 12 ply birch for this one.
The math is very simple, find the radius of your kerf, then multiply by two for the diameter. Then take the diameter and multiply it by pi. this will give you the length of the kerfed section. Then, divide that by 12 to find the spacing between the cuts. (Im sure someone else will chime in here with a different way to do it, but I used 12 cuts and it worked fine for me.)
I recommend using a few scrap pieces for practice
here is my first try, no math just spaced it 3/8" to see what it was like

not too bad for a first try.
now, for the enclosure. its for a pair of sa8v2s going in the trunk of a 66 impala
1.6 cu ft, tuned to 32 w/15 sq inches of port per cu ft

ill get more pics when paint and carpet are done, but not too bad for my first try, especially with a dual kerf. probably the hardest part was getting the kerfs to match eachother. more pics to come!

Looks good, man.

Have you considered using a roundover bit for the edges of the outside of the box? Helps a lot with carpeting, but even if you don't carpet, gives it a really finished look.

Good God, I'm going blind. I really need to stop jerkin'

Nothing to see here, move along!

And great work again. Really well done for a first attempt with no measurements.

You have to divide the circumference by 4 as well before dividing by 12. People do realize there is a video for doing this at the top of this section right? Looks good though

meh... I built the enclosure for free, except for cost of materials. so I didnt want to put too much effort into it.
