Ooooh, this takes me way back.  Agree with Graham and those of like mind.
Horizontal lead trimming is touchy stuff.  Saw a board that had "dropped"
into blade... Cool effects from traces peeling from sliced and diced pcb.
Poorly maintained saws created burrs on leads (ouch!), also saw fractured
joints that the assembly pros would dutifully touch up (did they really
catch them all?)
Prep work ahead of time will save manual touch-up and costly boo-boos
afterwards.  (And keep the bean-counters really happy...)  Use horizontal
lead trimming only if you must!
My $0.02 worth.
