Help!! I've started making a nice set of unit building blocks for my
niece and grandson out of 6/4 walnut and cherry. The unit block size
is 1-3/8 inches by 2-3/4 inches by 5-1/2 inches and all my other
blocks will be multiples of it. I want to make some of the Roman
arches and half arches out of a unit block. The problem I have is
that I don't know how to make each of them look exactly like the
other. Has anyone designed a jig which can be used on a band saw or
with a router to cut these shapes out? I want to make about 10 of
each. Thanks.

Check google, with "routing small pieces" and "rout small pieces"
to start.
I'd probably make a large, easy to handle, master.

A roman arch is a simple half-circle above the opening.
A 'gothic' arch has arcs that are the full width of the opening
the 'easiest way to get roman arches, is with the proper size drum
on a spindle sander. Ditto if you're making blocks with a quarter-circle
'bite' out of one corner.
Saw on the 'waste' side of the arch line,
Clamp a couple of stop-blocks to the sander table,
And then 'introduce' the block to the sander, until it hits both stops.
Voila!
I would set up a sacrificial fence on your drill press and use large
fortsner or saw-tooth bits to cut half-circles. Use a stop block and you'll
get identical parts. You could also make the parts twice as wide as needed
and drill a circle centered across the width and then just rip the part in
half on the table saw.
