Using a Lumber Rule

[@pureace23]

We have a few of these things lying around at work. I’ve always wondered how they work. We typically just go the long way and measure with a tape

You couldn't have explained that better, thank you so much!!

[@giulioluzzardi7632]

I needed that re-fresher after 12 years!

[@pumpkintown]

Wow! Thank you!

[@johnfitzgerald8879]

But how do you measure the length of the board?

[@ongminhhuy3809]

We have certain length for each grade of board.

Where can you get lumber rule I’m in Cumberland ont

[@PMolzahn]

Conway Cleveland out of Grand Rapids, MI sells them: www.conwaycleveland.com/lumber-rules

[@ARMYStrongHOOAH17]

I mean....length in feet times width in inches divided by 12.... is math that difficult?

[@LogHewer]

@@ARMYStrongHOOAH17 Not difficult, I guess, but any help is welcome when boards are being pushed onto a set of grading chains and you have about 5 seconds to determine SM, flip it and view both faces, measure cutting units between defects, and assign a grade and possibly mark rip or crosscut lines to remove defects and make grade, etc. Then on to the next one. Hit twenty big bunks of lumber like that a day and you'll take any help that's offered. 😅
