How to make a spinning hammer

For straightening dents on the car body and assembling furniture An inertia-free hammer is used that does not rebound after impact. Such hammers are also called space (or non-reactive) hammers, since they are used by astronauts for repairs. This is a simple, but for some reason not a cheap tool, so in order to save money, it is quite justified to make it yourself.

Materials:

• handle blank;
  
• pipes 40 mm and 50 mm;
  
• plastic blank;
  
• metal balls.

The process of making a spinning hammer

A piece 50-60 mm long is cut from a 40 mm pipe. A 60-80 mm piece will be required from a 50 mm pipe. The workpieces are trimmed whenever possible, ideally on a lathe.

On a 40 mm piece of pipe, you need to round one end and weld it into the center at a right angle to the second workpiece. The weld seam is cleaned.



Hammer heads are machined from a plastic blank. On one side they taper to an internal pipe diameter of 50 mm.

One striker is packed onto the tee.

70% of the volume of steel balls is poured into the hammer. It is then closed with a second striker.




Next, the wooden handle is turned and installed. To prevent it from flying off, you need to hammer in the pin.
