[TheForge] Pratt and Whitney was No forge messages coming in

[David E. Smucker]

Peter,

Pratt and Whitney made lots of different machine tools, and maybe still does 
along with being one of the world's great jet engine builders.  I think the 
best, better than Rolls Royce and I don't like anything made by General 
Electric (GE stands for Go Elsewhere if you have ever had to deal with their 
large motors.)  Pratt and Whitney was / is also famous for making gauging 
tools.

The tool you describe sounds like a stroker, really a vertical shaper as you 
say.  These were used to put keyways and such on the id of parts.  Not very 
common, and you don't see them in many machine shops today.  Generally to 
the "non-history machine shop market" they would have a value similar to a 
shaper -- scrap value.  We had one, and it is still there I think, in the 
large machine shop at Alcoa's Davenport Works.  Never saw it used -- until 
we had a breakdown that required us to work the inside of a large blind 
hole.  After cleaning the dust and grime off of the machine it really did 
the job to work the bottom of a damage roll end spade coupling.  No other 
machine we had could work the bottom of a large blind hole.

Dave
