Tip: Marking Centerlines on flanges/ And Rig Pins

[Gregg Brightwell]

I fabricated a little bracket that holds a fine point sharpie great. Sharpie goes in the big hole, the tip goes through the little hole. Keeps it square, and dead center on a 5/8ths flange.
Also, here is my deburr tool. Deburr bit in a cordless screwdriver. I have seen other folks do this. I did not take the time to make an adapter. I used tape.

Here, I took an old dull, 6 inch 40 bit and cut the threads off. Attached a flag, and Voila'... Rig pin
