[GreenKeys] Spacing Was: M28 Troubleshooting Question

[Don Robert House]

You are right on Steve!

Actually if requested (at extra cost) TTY Corp would paint the  
machines any color the customer wanted.
My first case of trouble on a 28 ASR was at the Massey-Ferguson  
Tractor Company. It was painted the color of their tractors.
Sort of Chinese RED.  When I was living in Fallbrook, CA I picked up a  
used 20 RO Cabinet from the Naval Hospital painted in Hospital WHITE!

Looked awful.

Just wanted to give the group an update. I was able to obtain a  
replacement part from Paul, (aka Mr_RTTY) and found some time Monday  
to make the necessary repair. Lots of fun with c-clips, springs and  
linkages, but it's all back together and running great! The spacing is  
now consistently smooth. Of course my ITTY decoder is now on the blink  
so I have nothing to print. Parts are on the way.

Next step is to find someone to media blast the M28 cabinet. What  
"authorized" colors did they originally come in? Might be tough to  
find something "living room friendly". LOL.

Thanks,
Cory

Found it!  Problem is, it's what you might call a hardware failure.  
There's a bracket that supports the pivot that plays a part in  
positioning the type box that fatigued and broke away from its  
fastener. It's semi-captive because of where it's buried but it  
appears that when the type box is required to line up for B,G,O, the  
angle is such that play in the mechanism is at it's max and the whole  
type box moves out of alignment. For the other rows it's either over  
center or under center of it's pivot.

Of course it's in one of those 'how am I going to get to it' spots and  
is a multi-function part.

Did my last pic make it? If so, I've got a snapshot.  -Cory

When you look at the position of these letters you will find that they  
are all in the rightmost row of the typebox when viewed from the front  
of the machine.  Note that D is one row to the left of B.  Tells me  
that the typebox is slow in positioning to the rightmost row or held  
back somehow.  I wonder if there is a little binding or something that  
is slowing down the positioning of the typebox.  Make sure that you  
are not using too heavy a lubricant.  Oil not grease and a light oil  
at that.
