Use paint strippers outdoors if possible. If you must use them indoors, cross-ventilate by opening all doors and windows. Make sure there is fresh air movement throughout the room. Ventilate the area before, during, and after applying and stripping. Never use any paint stripper in a poorly ventilated area. If work must be done indoors under low ventilation conditions, consider having the work done professionally instead of attempting it yourself.
When you need to duplicate multiple measurements on a larger project, it can be helpful to use a length of 1×2 or similar stock as a story pole. Cut or select a piece that is longer than the longest cut required. Carefully mark the height, width, depth and length of various parts onto the 1×2. The story pole will speed up marking for cuts, and matching parts will be cut the same.
