*Sigh* You are misinformed.... Federal never sued anyone for anything....the Hurricane came out first.... square as a matter of fact.
Federal copied that from ACA, ACA decided that the round horn design would be more efficient and easier/cheaper to produce. So, I once again set that record straight.
What is your source for the above information? A statement is more
believable when a source of the info is given.
Is it really easier/cheaper to produce a fiberglass shape like that?
Seems to me that cutting out 4 sides of cheap steel, putting
the bends in them and then welding them together would be
easier/cheaper than making that complicated Hurricane horn.
We have brake operators where I work that could put all the bends
in a T-bolt horn side in under 2 minutes. The steel sheet that T-bolt
horns were made out of was cheap stuff and welding it wouldn't
take hardly any time at all. I would bet the entire process for
the Thunderbolt horn was less than an hour total time. Maybe an
hour at the longest. I guess you would have to figure in the
horn support time too so I would bet the total time for manufacturing
a Thunderbolt horn and support wasn't over an hour and a half.
I would bet there's not much difference in horn cost between the
2 sirens.
Dad, what does that CD mean on that big yellow horn? Well son, I believe it stands for Cyclone Device......
