What is the purpose of those 1/2 inch cuts. And how much better is a table saw over a hand held circular saw...

Relief cuts to bend the wood

is there anything to adjust or factor in for kerfing when designing a ported box? if i had a specific frequency in mind for a slot port..what(if anything) do i have to change mathmatically to keep the box at that frequency?

Draw it and then measure down the center.

That's what I did with mine and I accounted for the flare giving a little more port area and I was pretty **** close. It looks to be tuned around 30hz and I was shooting for 29hz when It was completed.
