Constructing A Good Hospital Plate
Source: Farrier Rounds, Nov. 2000
- Use 16-gauge sheet metal.
- Use four screws, one at each "corner" of the shoe/plate, for stability when the horse places the foot. Drill and tap these corners.
- After nailing on the shoe, file the nail heads level with the shoe so that the overlying plate will fit snugly against the shoe.
- If necessary, to keep out dirt and moisture apply a thin bead of caulking between shoe and plate.
- Make sure the screws are only 1/2" or 3/8" in length; any longer and they can be screwed into the hoof. Ideally the screws are Grade 9 or greater.
- Provide extra screws to the owner to replace worn ones or melt a small blob of borium onto the screw heads.
- Use a lock washer as a spacer between plate and screw head for added security and to help keep the screw tip clear of the hoof.
- Apply a lubricant, such as WD-40, to the screw thread or hole before replacing the screw.
