After my garage mishap a couple of weekends ago I finally had time to install my new Lockhart Phillips frame sliders. Forget about directions. There weren't any. With the info available on this board I was able to do the install pretty easily. The lazer pointer method is da bomb!
The only tips I can offer are to use a 2" hole saw to cut the holes arfter you've made your pilot hole. I masked off the area to avoid scratches and get a cleaner edge. Also, hold the drill so that teeth of the hole saw are on same plane as the bottom of the mounting screw hole that is next to where you are drilling.
Results? See for yourself.
