Title: weights of green lumbers per/k
Post by: jaciausa on October 14, 2015, 07:52:03 AM
Hello, trying to find chart or information on the weights of green lumber per k bdft. The Oaks, ERC, Walnut, Hickory and any of the pines etc. Is there a site or reference that has this? Thanks for any help.

Take a look at the toolbox at the bottom of the column on the left side of the screen on this forum.  There is an easy to use calculator there.

Warren has a good answer for your question. If you don't find what you are looking for, give a shout back.

Also, for board measure we use MBF to represent 1000 board feet. (i.e. not k )

Thanks, I found the charts and what I needed. I am going to build a small kiln and I need a way to load with a jib crane possibly. I have a jib rated for a ton which appears to be to small.

How small is the kiln going to be?

I believe the smallest -new type Nyle L53 for a start. I have been studying all the builds and advice others are giving and believe I can use part of a 53 foot trailer I have that was a reefer unit with 2 side doors. It is backed up to ground level. There is really a lot of items to consider about kilns and the size needed loading and unloading. Building a kiln out of green lumber is the other option I considered.

1 MBF of freshly sawn red oak can weigh around 6000 pounds.  When air dried, however, it will weigh closer to 4500.  Most other species are lower in weight.  if you need a precise estimate, see the following publication that includes the effects of moisture species, actual thickness, width, etc.

Hello Gene, That is precise! Very good information that I hope I will need soon. I am tring to figure bundle sizes I can handle green,but knowing the board feet wet and board feet and weights dry will be needed just as soon as its dry. I am limited with my equipment and the width of the trailer I plan on using with the Nyle Equipment. Thanks for the help.
