Title: Mixed species in frame
Post by: addicted on December 03, 2017, 08:54:05 PM
Hey guys
Thought I'd start a thread on mixing species within the frame.
Has anyone done this and what type of considerations were in play? If you have pictures that would be great too.
I've gained access to hickory, oak, cherry, beech, and locust and originally ran numbers for eastern white pine.  Throwing in a different species here and there might add to the character if I can work within the differences in characteristics.

No problem. I think Jack Sobon has 14 or 17 species in his house frame.

A friend of mine did the same thing and it came out awesome. Lot of nice character. If I remember correctly there was hardwoods and softwoods: red and white oak, cedar, SWP, even some walnut braces. ooooolala

Over 20 in Jack's house.
You just have to be aware of the shrinkage differences. If one shrinks more than another it could open up a joint some what.

You can look at things like compressive strength for best crush resistance in say a heavily loaded beam over a post, highest E for a tiled kitchen floor, etc.

I used black gum for a high tension heavily pegged through spline in my shop trusses figuring with its interlocked grain even though the spline is hidden it won't be the first thing in those joints to get into trouble.
