Monster Plumb Bob

[schor]

I did post this to the project of the day, but I think it's appropriate for the projects forum.

The makings of a +10 inch ~6lbs plumb bob. I always wanted to make one and a friend wanted to have one. I scrounged the metal shops and found a piece of bronze for the main body, I used some brass and stainless I had in my stock and some rosewood and started turning.

Thanks for the positive thoughts on project of the month but I've seen tons of excellent projects on this site, this is only a plumb bob.

There is no such thing as ONLY a Plumb Bob. It is a precision piece of work if done correctly. If everything is not on a relative center line it will not work correctly. I have seen them off the mark as much as 1/16 inch. I can't imagine putting in a pipe drop from a 25 foot ceiling and being off that much at the floor. I have a Brown & Sharp that is Mercury filled.

Thanks Bill, I believe I did make it correctly. Everything should be on center and I hung it and there was visually no runout (is that the right term to use?). I'm not really sure how accurate a plumb bob needs to be or how to measure it's accuracy other than to let it hang and see if it stays on center when you spin it a bit.
