They are fun to make and give as gifts.
Step 1: Tools and Materials
Chisel (be sure to buy chisels pre-sharpened)
1/8 inch drill bit
5/16 inch drill bit
Step 2: Find a good starting branch with "crotch"
Step 4: Cut off excess appendages
Step 5: Mark wall side for rip cut
Position the branch roughly in line with the blade.
Step 6: Rip cut the wall side
Place the table saw's fence lightly along the right part of the branch.
Use a rip stick to help to guide the branch back through the blade, and use a regular push stick to guide the branch from its end.
Complete one pass, turn off the saw, raise the saw blade another centimetre or so, and repeat.
