Machining a crank pulley

I want to get my three belt crank pulley machined to handle just the single alternator belt. Obviously preserving balance in the pulley is critical in the machining process. Any advice about good questions to ask the machinist that has agreed to consider the job?

Believe me I have searched online, and made five calls, and despite the huge aftermarket for Civics there are now no simple bolt-on options for a single belt crank pulley conversion on a sixth Gen (non-VTEC) SOHC Civic 1.6L engine. Unorthodox Racing is out of this game. Ralco makes them for the 1992-1995 but one guy on Honda Tech says he does not think it'll fit a 1998 D16 because, he says, he couldn't swap the stock pulley. Lastly, ATI's pulleys are for serious racing and too expensive.

I know the benefit is small, maybe enough rotational mass reduced to "save" a couple horsepower at the most. But I do a lot of P&G and I have to do the timing belt and therefore the pulley has to come off and therefore this is the simplest time to attempt this mod and so... I'm learning.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
