Any good "How To" on grinding piston rings?

trying to figure out how to best gap and grind piston rings for my first ever engine build (Miata). Anyone got any good videos or a good write up on how to best do this?

Thanks.

I believe that the magazine had an article on rebuilding the Subaru engine that talked about this. On my phone now, so not the easiest to find.

One of these

and some of these

0.0045" X bore size in inches is your gap.

Go nuts

from what ive seen the hand crank grinder is the easiest cheapest and best way to keep from removing too much material.

I use my belt sander, but I'm also pretty damn good at working to the thousandth on it.

Last 2 engines i build, i used a hand file and a lot of time

Let me clarify. I found the tools your supposed to use before I started the thread. I've just never used them before so I'm trying to learn how to use them. :)

That Circle Track article was pretty good. Anyone else have other articles or videos?

Thanks.

Googling "gapping piston rings" will get you an infinite number of tutorials. Not much to it though, put it square in the bore, measure gap with feeler gauge, remove material, repeat until proper gap is reached, deburr, install on piston, repeat till you run out of rings.

Thanks.

"gapping piston rings" worked. I was striking out on other terms.

In most cases, the rings won't need regapping.

Provided they are the correct size to start with.
