How to round portedges

[G DANE]

I just honed a 30 HP i have apart right now. This one sat for decades and was never apart before. The edges of the ports are sharp as a knife. What do you ude to round off them a bit ? A Dremel thru the ports ?? or is there some better tool ?

Carefully! Use a ball point in a die grinder, or a sharp , curved chamfering tool. That edge just has to be broken, not ground away.
