[GreenKeys] Mod 28 Gearing

[John Lawson]

Greetings Greenkeys!

I'm about to order a set of gears for the Tempest Mod 28, which I am 
told - (how to verify?) is a 75wpm machine. [hmmmm mebbe it ain't - best 
go check...]

Tom Tillson kindly sent a chart summarizing the gearsets for the 28s, 
KSR and ASR.

Of course my goal is to send and copy RTTY at 45 baud with this 28. It's 
a KSR so no re-perf or td.


So, from the chart, there is gearing for 65wpm - 390 opm, 45.5 baud, 
7.00 unit code. There is a motor pinion and the driven gear.

Keyboard (LAK)  gearset 173795   consisting of:

Gears:     173794 14 tooth

                  173793 100 tooth

Isolator   159287

Gears:     159278  14 tooth

                  159279  96 tooth

Paul Cembura suggests  the 161293 / 45.5 / 7.42  set. I had originally 
asked him for the 173795 / 45.5 / 7.42 set.


I understand a bit of the relationships involved - but in practical 
terms - which is "better"??
