First off you must understand to be very careful while homemade treestands. It is not worth being unsafe with the idea. Make sure everything you use is durable and of good condition.

There are two methods you should really know, and you don't need directions. Make them to your comfort level. If your bigger, make them bigger. If you like them exteremly high, out them high.

You can either make a ladder stand or a hang on stand. The ladder stand are more safe and can last longer depending if you use metal or wood. Hang on stand must have alot of support and changed every few years due to rot. If you choose the hang-on method, I would put the platform on a large branch or something to put some tension on the tree and less on the stand. (DON'T use nails on a homemade treestand)
