It's a challenge to put antennas on floats and meet the TORC
requirements for only vegetable matter to be exposed. We got a special
dispensation for our 23cm ATV from the JPL float.

Things sure have changed in 40 years.

Nicely done float. How tall is it? We had stability problems with
some of the floats. The parade route was fine, but entering Victory
Park at the end was tricky. One year, some of the floats almost
tipped over.

Also, my fault tolerant memory has failed me once again. The snoozing
photo of me is from of the 1970 float:
http://cpprosefloat.org/site/plugins/autogallery/autogallery.php?show=7.Past%20Floats%2F350.1970.jp g
The float consisted of 3 islands, connected with big long throw
hydraulic rams. The float could be contracted to about 35 ft or
extended to 59.99999 ft. The fun part was turning the Orange Grove to
Colorado corner in front of the cameras, while simultaneously
extending the float. Some officials didn't know which way the float
was going to go and ran for cover.

The sheared hinge bolts were from the 1971 float:

It also features an elephant toy, with targeting controls for a small
water pump and nozzle in the trunk. That was banned the following
year.


70 & 71? Maybe you met Dave Steinfeld of TORRA . I worked with him
for some years back in the day (80's).

Nope. I don't recall the name. I only associated with radicals,
leftists, protesters, anarchists, dissidents, draft dodgers, and a few
engineers. If he was anything resembling a normal student, I probably
didn't meet him. Also, I don't think that TORRA existed in 1971 and
befo

There were very few active hams involved in construction of the floats
at Cal Poly Pomona. I think there were only 2 or 3 electrical
engineering students involved. At the time, the design and
construction was dominated by Agricultural Business Mgmt students. It
was easy to tell the difference. Engineers wore cowboy boots and ABM
students wore suits, string ties, and carried brief a case.

Don't recall how tall it was, but it laid back down to get under the
overpass at the end of the route. It was built by professional float
builders (Phoenix)
http://floatcam.caltech.edu/ has a link to video clips during
construction, etc.

Would that be WA6ZVE? He works in the RF Cal lab here at JPL.

My Real Media player is having its usual bad day. I'll look at it
later.

I forgot about the overpass. That would be a problem. One year,
someone built a float over a large fork lift. The plan was to lower
it at the overpass and again at the park entrance (due to overhanging
wires). When the forks were lowered, the skin of the float was
shredded. Someone used baling wire to tie together the ends of the
chicken wire skin at the junction. Oops.

Cal Poly traded space in the Rose Palace with D.E. Bent and Sons. I
think he retired in about 1978. We supplied him with surplus labor
(mostly for decorating and handling flowers) in trade for floor space
and "borrowing" tools. It was a very professional operation.

One of the funniest things was watching Disney Animation attempt to
build their first animated float. Everyone expected big things from
them due to their experience at Disneyland. As expected, the float
had more moving parts than stationary. Just one problem; Disney ran
on pneumatics instead of hydraulics.

The centerpiece of their design was a rather large globe with a
satellite spinning around it. The globe was bisected at the equator
with a cantilever rod supporting the satellite. It, and other moving
parts, sorta worked. Then, they added the flowers and watered them.
That added lots of weight, which they hadn't expected. The support
rod bent and had to be reinforced. Instead of smoothly orbiting the
planet, the satellite lurched and jerked its way around the globe. The
pneumatics could not overcome the added friction. The pressure just
built up and up until the satellite suddenly lurched free. This was
repeated every minute or so. I vaguely recall that it finally died
about half way through the parade when some hose or fitting finally
broke from the concussions. By then, all the flowers had been
catapulted off anyway.

That call sign sounds right. The home / station address matches the
lookup to my address book. That is a good enough match for me.
