Re: [amsat-bb] Thrust Bearing for Glen Martin Tower

[John Price <n4qwf@xxxxxxxxxx>]

Richard, I bought a Hazer from the estate of a ham that passed away a 
couple of years ago. Glen Martin makes these. I bought a new bearing from 
them to mount on it and it did not match. I called them to see what gives 
and you could not ask for a more helpful fellow. I got the women to connect 
me to a service rep. and he got the measurements for the holes in the Hazer 
from me and had there shop make me a new plate for the Hazer. He shipped it 
to me and would not even allow me to pay for the shipping. At some point 
Glen Martin had to change to a new bearing company and I am sure the new 
bearings did not match there equipment so they likely just started drilling 
the holes in there new stuff to match them. The old stuff wont lineup and 
that is what I ran into. So why don't you call them back and explain to the 
fellow there what you have and I bet he will try every way possible to make 
you happy. I told him I would redrill the holes in the old plate of the 
Hazer and he said he did not wont anything he made on anyones tower that 
did not work like it should. I was very impressed to say the least. Hope 
you can get that guy on the phone too. 73's << John
