Here are a few ideas for the left-overs.
Step 1: Materials
1) (Optional) Saws-All aka reciprocating saw with branch cutting blade (to cut down branches into rough lengths -- see photo)
2) Table saw (to rip [i.e. cut length-wise] branches)
3) Chisels (Note when you go to buy these, make sure that they are pre-sharpened; some are not)
4) Dremel (for scroll work, sanding, tweaking)
5) (Optional) Electric sander
6) (Optional) Router (to carve indentations as needed)
7a) 1/8 inch drill bit
7b) 1 inch drill bit (or larger)
8) (Optional but a good excuse to get one) Nail gun
9) (Optional) Electric planer (to smooth down trunk slices)
10) (Optional) Jig saw
1) Tree and branches
2) Denatured alcohol (to remove sandpaper dust)
3) Dust mask
4) Sugru (for various hold-downs)
5) Wood glue
6) Drywall screws
7) LOTS of sandpaper, 150-220 grit. No matter how much you buy, you'll never buy enough. I recommend the red Diablo brand; expensive but worth it
8) (Optional) Stain
9) (Optional) Polyurethane
Step 2: Dictionary O' Terms
Banana cut or slice: A round slice taken out of a branch, much like the way you slice a banana for a peanut butter sandwich.
Banana split: A length wise split down a branch, much like the way you cut a banana length-wise for a banana split. Some people also refer to these as rip cuts.
Thingy or thingie: An object of some sort that you are supposed to understand.
Butt table slice: Same as a banana cut , but taken out of a trunk rather than just a branch.
Crotch: A limb containing a branch that shoots out at a good angle for making a hook. Warning: a crotch stick can be rather itchy, though. (thanks to spanner1969 and annabelle's mom)
Miter: A cut that miter-might-not be exactly 45 degrees.
