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

[Mike Hanz]

Pin punch is U.S. convention, John, and has been for many years.  I just 
bought a new set of Starrett drive pin punches, and they have the same 
name in my 1938 Starrett catalog.  However, Commonwealth countries seem 
to generally call it a pin drift.  Same problem with a spanner versus a 
wrench. Need to keep in mind the audience around here - they sometimes 
get all bound up in nouns that mean the same thang.  That's why I simply 
called the "dynamotor pounding tool" a "1/4" brass rod..." :-)   I *do* 
like the term "podging tool", but its use might be limited to some 
obscure corner of Liverpool or something...

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.
