Inexpensive DIY golf ball file handles

 Using a file without a handle is very dangerous. When I worked as a diesel mechanic I seen this clever idea on the shop floor.

Do not use this sort of handle if you are intending to use the file on a lathe.

1. Find some golf balls.  Used balls can sometimes be bought at garage sales or could be found at the local golf course in the water hazards. (ask permission before retrieving the golf balls from the water hazard)
2. Find all the files that need handles.
3. Drill a hole 3/4 of the way through the ball the same size as the smallest portion of the file (the part the handle would usually get a handle placed on it). The hole is more or less a pilot hole and makes it easier to beat the ball on with a dead blow hammer or mallet.
4. Place the file handle side pointing up and the other end on a block of wood. Now beat the ball on with a deadblow or mallet.

Warning!: Files are very brittle, so do not get carried away beating the ball onto the handle
