[GreenKeys] Re: TP 173979 Print Hammer Head

[W8MAQ at aol.com]

I have typing reperfs with each type of print hammer/head. Evidently they  
are not directly interchangeable unless one changes out the pieces "behind the  
scenes" in the guts of the machine.
 
I asked here a few months ago about a replacement Delrin hammer head,  with 
no success. If there is a way to fabricate suitable substitutes, I'd like  to 
get a couple of them as I'm missing two.
 
Thanks es 73 Jim W8MAQ

Hi  Don:

I have quite a few typing reperfs around, but have never worked on  one.

On two 35s, I cannot really see into the area where the hammer is  located.

On two 28s, I can see the notched lever arm as show in your  diagram, but 
there are no hammers.

On another 28 typing reperf, it  looks like a there is not supposed to be a 
hammer, since the lever arm is  flat and horizontal (not vertical like the 
others).  Were there some  reperfs that used just a flat metal arm to strike 
the ribbon?

Then  I have this other 28 reperf, a brand-new still-on-plywood unit that I 
got  from Jay Waller, may he rest in peace.  This unit looks to have the  
hammer.  However, I do not know how to disassemble this unit.   What's 
involved?

thanks,

gil
