 I agree.
 When I was a kid in 1972 I used Freddies method on a new D at a local college.  It has held up well all these years. Now the action is tired and I will get a chance to revisit this old friend this year and see how they held up. The problem was that the parts were never fit correctly in the mother ship.  This issue could have easily been resolved in the factory at the time of manufacture.
  Water under the bridge, Aye Horace?

It wasn't until things were largely at crisis level that Freddie Drasche started teaching his home-grown technique of rolling brass center pins between two files.... 

 
Too bad...still an excellent concept...once fully worked through, it's very stable and will last a long time. 
 
Best.
