10' Box Beam Level
10' Box Beam Level
(OP)
Anyone out there know of a supplier for off the shelf 10' Box Beam levels. I am currently trying to find such a monster and not having much luck. Any help would be greatly appreciated.
P.S. I've tried googling and only found up to 8' levels.
TIA

RE: 10' Box Beam Level
It doesn't seem to be the best way to do it, but right now they are having to relocate the 8' Level they are using after taking a first set of measurements. Which throws more error into it so we may not even be seeing the true measure of the bow in our parts.
I'm unfamiliar with the term "water Level"

RE: 10' Box Beam Level
Aluminum I beam of suitable stiffness should be pretty straight to start with, but if you need better you could have the flanges machined straight and parallel.
If you need to check level as well, you could attach the 8 foot level to the beam.
You can also check bow with a laser. Set it so that the beam just clears the high spot. Small gage block and a scale moved up and down the entire length and note where the beam hits the scale.

Here is a brief description of a water level http://www.weldinginspectionsvcs.com/misc/WaterLev... (Not practical for what you are doing) but would check bow over much greater distances than strings etc.

RE: 10' Box Beam Level
the starret aluminun straight edges are designated "ASE-inches" I think their longest is 96" though.
RE: 10' Box Beam Level
I've seen 6'-8' blocks go for rather cheap prices (not including shipping costs) on websites like e-bay. Maybe you could find something similar for your use.
RE: 10' Box Beam Level
I appreciate all your good suggestions. One of the other concerns I have is with the total weight of whatever I end up using. All I really need is a Straight Edges that has a straightness of .012 over 8'6" of the 10'. I am working with our quality guys for possibilities. We may be able to use a Blocks and Line setup. We need to make this easy enough so that the operators will use it to make the check on the specified number of pieces. This will be an in process check so that adds another realm of issues into the equation.
Again thanks for all the good suggestions, I am looking into what will be the best.
Thanks to all.

RE: 10' Box Beam Level
Thanks for the response. However I need to have Straightness of no more than .012" over 8'6" span.
I have gotten with one of the quality guys, used to make the parts we want to check, and we are going to look at some simpler ways to do it, using some of the suggestions from this post.

Go, ask your punch operator, Butchie Boy, how to do it. It'll be done in the time it took to write this.
