A router can do it in one cut if you do it this way.
Make a pattern out of hardboard or plywood
Trace onto your 3/4 ply
Cut out freehand on a bandsaw or with jigsaw leaving the line
Attach pattern to your 3/4 using screws or double-stick tape
Use a pattern cutting bit in your router to make the finish cut
OR
Attach pattern to your 3/4 with screws or double-stick tape
Make 3 passes with your router taking ~1/4 at a time
This method requires a thicker pattern

here are some things to read to get you going in the right direction:

Yes, you want to make a template that can be followed by a router with
a pattern bit. Cut the wod to within 1/8 of the final shape by hand
first then use the template and trim to final shape. If you
If your shapes can be described as true arcs with ogee intersections
then you can create a very accurate template by laying out the radius
centers and using a router circle cutting jig to cut the template. I
like using MDF for templates. It is real easy to cut and shape but it
will wear out if used a lot.
If you have elipses or can't setup a router with a circle jig then you
can use a trammel and ships curve to layout and draw the shape for the
template. If you use this method and free hand cutting with bandsaw,
handsaw, etc. then you should cut just outside the lines and sand down
to the line using power sanders like an oscillating spindle sander,
belt sander, edge sander, belt sander or what ever you have on hand.
Not much description on actual process for router circle cutter or
trammel written here but you can research them eleswhere terms.

1) Some 1/4" hardboard for patterns, a router with a 3/4" pattern bit,
and a saber saw with a 10TPI, bi-metal blade.
2) Make templates.
3) Trace template on 3/4 material, remove template, then cut 1/4"
proud with saber saw.
4) Replace template, clean up with router.
5) Get a beer and critique your work.
Have fun.

Make a hardwood template where the router bit bearing will ride. Cut
the shape on a jig or bandsaw such that only 1/8" will be trimmed with
the router. A 1/2" shank bit is better than a 1/4".
