Always wear thick gardening gloves when handling broken glass, and use goggles if you have to break any glass. Carefully crisscross pieces of masking tape over a broken windowpane. Cover the glass with a heavy cloth, then tap with a hammer to break away the pieces from the window without splintering. Dispose if broken glass in newspaper.
If you need to cut a bolt to proper length, first thread the nut on, past the cut mark. After cutting, file- off sharp edges, then back the nut off to clean up the threads. To clean up rusted or damaged threads on a bolt you want to salvage, cut a slot through the side of the right-size nut. Clamp the nut halfway into a vise with the slot down, then run the bolt into the nut. For more cleaning action, tighten up the vise on the nut.
