fittings. They are made of 1X1 6061T6 - 4 abot 4 1/4 inches long,

4 about 5 1/2 inches long.
2 need 1/4 inch slots, 4 need .195" slots, and 2 need 3/16 "
slots -
all 1 3/8" deep.

O.K. That 1x1" -- is that square solid stock, or angle stock?

Solid 6061T6

And the 1-3/8" deep suggests that the cuts are from the end, not
through the thickness, even if it is solid square stock.

It is through the thickness, from the end, to make a "fork"


My Clausing 8525 which is half the size of a Bridgeport can cut a full
depth (1-3/8") slot with a 4" slitting saw held in the cheapest of the
MSC arbors I referenced, though I have to make multiple passes because
the 1/2" collet doesn't transmit much torque. The example I have close
at hand is a home made 3/4" steel boring bar slit 1-1/8" deep into the
end, to tighten onto the bit.

It should be easier in aluminum with a new saw instead of the used
ones I cut steel with.

Makita panel saw blades are cheaper and somewhat larger:
