how to make floor track for pocket door
I recall Brickeyee recommending to place a piece of angle iron on the floor to guide a pocket door without the need for those plastic guides that eventually scratch a door. I'd like to do this for a pocket door I am currently assembling. Brickeyee, would you give some advice? I assume the length of the iron could be fairly short, say 18" situated just inside of the door itself. How deep do you make the groove in the bottom of the door and how do you make that groove? It's not clear to me what tool I have would make a straight clean groove in the bottom of a door.
Is there some sort of channel I can buy that could be mounted into the door for the angle iron? Maybe that avoids the difficulty of cutting a narrow groove.
