I also understand maple gets harder as it ages, and this stuff's been sitting in the barn since the owner had a heart attack 7 or 8 years ago. Just another reason I'm probably gonna go with the pine from the sawmill

Dry maple is much worse than green. I'm working some white oak right now that's been sawn for less than two years, and I've broken everything but my boring machine. I can't imagine working year old maple. Maybe with power tools.

Hi Devin,

Sorry, we have now 6 frame going on so I have been tardy in my responses. Dave S. is more than correct. I had no idea that the maple you were considering was not fresh from the mill. It would be more than an arduous task to frame with it. I also do not encourage folks to frame with the Maples and Birches with out some years of experience under their belts. Beautiful wood, however, one must truly know the timber craft and the species like this to work well with it.

You will love the White Pine. It is a marvelous species to frame in, especially for a your first project.

I have worked with maple, I'm going to use a bit of fresh sugar maple on my next barn just because there are a few trees standing where the building needs to go. It's not really that fun.

But I can take you to a super nice Swiss style forebay barn a few miles from me, the lower beams are ALL sugar maple (probably for the same reason, the trees stood where the barn needed to go)

After having worked with white pine, I seek it out for everything now. I've become a pine man.

Thanks for all the replies everybody,
After the overwhelming response, I'll definitely be going with the pine. Have run all the numbers, it works out to only a few hundred dollars difference, and I think we'll just call that my salary for labor.

Pine is a nice wood to work. Another favorite of mine is popple, similar workability as white pine but fewer knots. Haven't worked it in a dry state, but a 2" mortice is no problem with my boring machines in green wood.

I would encourage you to try a few different species, it builds character, in you and the building.

Ok so we'll figure the sizes based on using EWP.

Jim,
Thanks for refocusing the thread. Sorry about the delay, I've been traveling for work.

I ran the numbers through an online beam sizing calculator as a 4x4 EWP spanning 11' with a 1000 load and it failed in bending and deflection.
You need a large timber or some other solution like closer spacing.

To get a timber that will pass at this spacing and span you're going to need at least a 4x7.

Hi Devine,

Here is a design of a Pavillion we will be installing at a pool facility in Fairfax, VA just outside of Washington DC in September. It is 4.8m x 7.2m (16'x24') with a 4/10 pitch (22 degree) common rafter system of 100mm 100mm (4"x4")rafters that are a 600mm (24") on center, and span approximately 2.4m (8')

Your design just needs a little tweaking to work, even with square rafter stock in the smaller dimensions (4x4 to 5x5.) I would have a PE check out the final design if you are not certain of your math. There is a lot that can be considered on roof loads, including pitch, and deck diaphragm configuration that can influence load capabilities, such as double layering of plywood (should you go the sheet good way) spline, toggle, or t&G board stock.

Regards,

jay
