What tool to transfer large bolt holes

[Wile E Coyote]

Whatcha fellas use to transfer large bolt holes when mock fitting fab parts? I'm thinking about a self-centering punch, right? Or what?

Sharpie?


Just kidding. I use a scribe for the OD and a centering punch for the ID.

Thanks, just what I was looking for, I just didn't know the name of it.

Thanks, to you too, D'Animal. I've been doing the same as you, yet I find it's not precise enough. (prolly my own lack of technique)
I'll need a set that goes larger than 1/2"....I'll have to do some more poking around.

Should be able to find them at Enco...

And thanks again. I was finding they all ended at 1/2" thus far.

If all else fails, I use a hole saw really close to the size I need and scribe around the out side. A hole punch ground down to 1/4 inch straight shaft gives a center mark pretty much dead on.

You can also use drill bushings.

They make them up to 1" at least...we have them so I know they exist.
