When I put up lock ons I start with a cordless drill. For the steps I drill a pilot hole first. It makes the steps go in a lot easier. Then I only use the kind with the anchor bolt in the bottom, or the lone wolf style mentioned above. I then throw my rope over a limb above me and pull it up. I then set it on my bolt in the tree. Then strap it. This is the easiest I have found. After doing this about 300 times you get good at it. BTW make sure to use a saftey belt of some kind. It is safer and easier.
