I was reading my haynes manual about installing new pistons and it said I needed to chamfer the block. What the hell is chamfer and how do I do it? Is there a tool to make it easier?

I come from a land down under
It's putting a 45 degree cut on the top lip of the bore.

You can use a handheld deburring knife or a curved whetstone.

Not at all with the deburring tool!

See the blade at the top?

It can rotate as you pull it around the bore and will give you a nice radiused edge instead of 2 sharp edges like a chamfer tool will!
