Taking out logs for timber frame for the house. Like some advice on species

[Blueberries]

Hi , going to be buying a sawmill this spring. 

Right now, I'm pulling out logs for the house including ones that will be the main timberframe bent in the middle- 4 posts, 2-3 beams with scarf joints and 3 girts to hold up the loft.

I've already milled a 20 ft 8X10 beam and a 13 foot post from red oak and am hoping to make the rest from red oak.- another 20 ft beam and 3 posts.

But, since I don't have that many red oaks but lots of Am. basswood, I was thinking of using American basswood for the girts. 
Does anyone see any problem wth this?

And, since I have lots of hard maple, should I just make them out of hard maple?  I know the weight here could make the timberframe more difficult to handle thus, using Am. Basswood might be a better choice.

Any thoughts?

Welcome to the forestry forum 
I do not know if basswood was used in timber framing but I do know it is a very important flowering tree for the honey bees .They used to cut down lots of them years ago to make the wooden sections for comb honey because liquid honey was harder to produce.There are lots of very knowledgeable timber framing members here .
If you fill in your location you might get more advice.

I'd save the oak for beams.

Never worked basswood?

Sugar maple is very strong, but it will be a bitch to work when dry.

Thanks, yes, I finally figured out how to change my location and a few other things! That was good advice - re location.

I figured that about maple.

Basswood is very soft and I know that it's used for carving. I don't think that it's too weak to use as a girt, especially since I'm making the them 8X10.with a span of about 11.5 feet. Another species that I could use is Largetooth Aspen (Populus grandidentata)

If you have white pine available, i'd use that.  lighter, easier to work with yet strong and moves, twists and shrinks the least.  Mill cants 1" larger than your final product.  just before install, mill off the warp and twist.  use a new sharp blade and it will look more milled and less rough sawn.

Thanks, I do have a couple big white pines, but, I would never cut them bcause they are so majestic and amazingly beautiful! They are over a meter in diameter and 40 meters plus tall.
