A repair kit can be used to repair broken interior door handle assemblies on certain vehicles, and replaces the original equipment door handle support housing with a replacement housing, without having to replace the entire door panel. The method includes removing the original (broken) door handle housing from the back side of the door panel by drilling or otherwise removing the plastic rivets that secure the original handle housing to the door panel. The replacement housing is then installed on the back side of the door panel in place of the original and screws are installed into drilled-out plastic rivet locations in the door panel through apertures in the replacement door handle housing to secure the replacement door handle housing to the door panel.

A method and system for achieving compliance for a fire-rated door assembly. To comply with fire rated door assembly codes and compliance, all components, including hardware must be listed and labeled by a certification agency, such as Underwriters Laboratories (UL). The disclosure may include a hardware preparation filler solution which allows fire-rated doors to maintain fire rating and compliance when removing or modifying hardware, or converting between hardware types.

Methods of forming an earth-boring tool may involve attaching one or more cutting elements to a replaceable cutting structure and positioning the replaceable cutting structure proximate a region of a body of an earth-boring tool that is susceptible to at least one of localized wear and localized impact damage. The replaceable cutting structure may be secured to the body. Methods of repairing an earth-boring tool may involve bringing a replaceable cutting structure proximate at least one portion of a body of an earth-boring tool exhibiting at least one of localized wear and localized impact damage. The replaceable cutting structure may be attached to the earth-boring tool at the at least one portion.

An earth-boring tool includes a tool body of a fixed-blade reaming apparatus configured to be coupled within the drilling assembly. The tool body has a longitudinal axis and at least one reamer blade configured to be outwardly extendable for use in an expandable reamer and attachable on a fixed-blade reamer. The at least one reamer blade is attached to the tool body in an immovable manner relative to the tool body during use of the earth-boring tool in the formation of a subterranean wellbore.
