Pecan and Hickory are very similar woods. In fact you will sometimes find it labeled as Hickory/pecan.
I have built several kitchens using this wood for the face frames and raised panel doors. It worked quite well with no problems.

I've never used it, but I do have a small piece saved in the shop that was given to me by a friend, so just waiting for that right "Just Because" project to come along.

Hickory, pecan, walnut and chestnut are all related but they don't all work the same.  Pecan has black spots in it that are sometimes hard.  These little spots which are not in any hickory I have ever seen will also make the pecan more prone to splitting.  That's the only unusual element that I am aware of in pecan.  Makes beautiful finish.  And, if you put pecan in a fireplace, these same little black spots seem to have a firecracker built inside.  It will pop out of the fireplace and making the popping sound.  It's worth the experience.  Hope to see your projects. 

I haven't worked pecan yet but I do have a couple of pieces aging that I plan
to see what I can do on my lathe.

However, we do use quite a bit of green pecan wood in our smoker when
cooking chicken, ribs, brisket, etc.   It gives the meat a great smoke
flavor that I think beats any other ( I'm sure I'll get a lot of comments on
that).

So, when you do use pecan on a project, don't throw away the scraps,
use in to get a great smoke flavor when barbequeing.

Thanks for the tip Al

I've heard apple wood is really good for smoking too but haven't had the opportunity to try it yet, but have used hickory and mosquite

I haven't used apple because, lets face it, we don't have many
apple trees here in south Louisiana, but I did have a crab apple
that I had to cut down to build my screen porch and I used some
of it for my smoker and some to make bowls.

It worked fine for both.  The wood is a beautiful pinkish color.

Actually, any fruit or nut wood is good for use in a smoker.

I have used pecan, pecan shells, plum, crab apple, pear, wild cherry,
and even live oak and they all work fine.

I haven't used them myself but I have been told that dried corn cobs
also work well.

i built an sunken living room out of pecan. i cut down the tree had it sawn into 1 bys. the lumber company in my town has a kiln for wood so i had it dried, then planed to 3/4 thick and tougue and grooved. it works like any other hardwood just keep your saw sharp with a 60 to 80 tooth blade. i did the sides and the ceiling then a satin poly. fantastic.

 I have used all types of to smoke with. Some of them are walnut,hickory,apple,cherry,and yes pecan. When the people came by to trim the trees along the right of way they trimed my pecan,I kept the limbs and then asked them if they would chip them up,to make a long story short they did and I use that for smoking.Most people will give you the wood if you pick it up.Just ask,and keep an eye out where they are trimming.

My kitchen cabinets are all made of pecan.  I love the wood.  My cabinet person loves working with the pecan.
