[ARC5] Some nonsense about drifts and the English language. (Was bearings for DM-28 dynamotors)

I am in agreement with you on that. My only point for commenting on this subject was so that any members anticipating this re[pair ask for the proper tool when they start the project.

One thing we should keep in mind is the knowledge of your audience. Many members of this group have knowledge of electrical terms but not necessarily machinist terms.

When I write a technical paper I include an explanation of the technical terms in the body of the work or in the appendix.

The term for the proper tool in the application of removing a pin (or in this case a shaft from a bearing) form an assembly is a pin punch ( or sometimes simply a punch). A Drift or Drift Punch (also known as an alignment tool has a tapered shat on the business end so that it may be inserted into two misaligned holes and driven in to "drift the two items into alignment. Because of the tapper of the shaft damage could occur if it is over driven when used to remove a pin or shaft from an assembly. A punch has a strait shaft, and by using a punch of slightly smaller diameter than the pin it can be driven through with no damage to the assembly.
