But back to the question,
back when I built a few, the usual method was to stack 3 (or more) Frued Diablo's, the thin kerf 7 1/4 in cheep versions to cut multiple strips at one time. I didn't see the need myself though.
The easy way is to buy 2x stock, and rip it to 2x2 blanks. Then rip the blanks to thickness, keeping them in order on a long outfeed table (I used just a tee made of 1x6's, which I when used to hold the strips during layup). After each blank is cut, keeping the strips in order, tape them back together tight with box tape. This gets them back into roughly the 2x2 shape. Then rotate them 90 degrees and cut them in half, (effectively cutting 2 at a time). Again, after cutting, tape them back together, to keep all the strips in order, so that you can lay them up in pairs.
This also lets you cut the strips qtr sawn no matter what the raw stock is. Just so it's clear.
If you want to do the B+C edges, mill that after cutting the strips in half.
