Philly, I've always cut it by hand. I charge 6 hours per 150 mm joint length, with a 5% discount for each additional 150 mm length (or part length) of it up to a maximum discount of 30%.
Therefore a 450 mm joint length works out at 14.5 hrs, and a pair of the joints this long at either end of an inverted U shaped assembly is charged at 25 hrs to the nearest 1/2 hour.
Below is an example of a pair of the joints at about 500 mm long each. At this sort of length it gets very tricky to assemble, and you need a slow setting glue like liquid hide glue or a slow setting epoy resin.
I've not attempted to execute it using what seem to be the US style machining methods you illustrate on your website-- well it looks like a Biesemeyer type rip fence, and I recognise the cross cut fence from when I lived and worked in the US, and of course there's no riving knife or crown guard anywhere to be seen, ha, ha--ha, ha, ha.
You must be a fan of old no-guards-n'-nail-gun-Norm, ha, ha. I can't get away with those sorts of dodges in my working environment. HSE would probably close us down in a flash.
As to working the joint in your proposed project Zebrano is often pretty stringy due to the interlocked grain and if that's the case joints aren't easily worked and planing results in tear-out and spelch can be a real problem.
Preparation for polishing is often best done with sanding techniques-- thickness sanders and stroke sanders being good options because hand sanding can take forever and the surface can end up badly hollowed and humpy looking. Slainte.
