The Water Wagon Project was suggested by Dan Cook to provide a
means to dampen the decomposed granite of the OFOF taxiway in order to minimize
the dust and debris pickup when planes taxi in and out at our events. We
put out the call for a donation of a suitable tank of 500-600 gallons but
received no response. So we decided to build our own tank out of 2x4's
and plywood and line it with plastic sheeting. The heavy duty trailer was donated
to OFOF last year and the 5 hp Briggs and Stratton engine was provided
by Mike Gannon. We searched for a suitable used pump, but finding none,
we ended up buying one from Northern Tool. The spray bar was made from
PVC pipe with 5 conventional adjustable garden spray nozzles attached. A
union at the input end allows adjustment of the angle of the nozzles, when
necessary. We started with them pointed straight down and found
that worked perfectly well so left them that way for the duration.
The construction of the Water Wagon started on 25 April
04. The builders were Dan and Joe Cook. The sequence is shown
below. The file name contains a date code (Y,M,D) that indicates when
the photo was taken. The first test of the Water Wagon occurred 9 May
04 and everything functioned more or less as planned. It got its 'public
debut' at the EAA Chapter 1112 Annual Fly-In and Airport Appreciation Day on
15 May 04. Outside of some uncommanded engine stoppages due to flaky
carburation/fuel pickup, the day went well and the Water Wagon received favorable
marks from all involved.
The latest update to the Water Wagon has been the addition of a Filler
Hose. The 25' 2 1/2 fire hose was donated by retired Fire Captain, Rod
McGrew. We built a support plate for the outlet end and screwed the
existing hose fitting into a close fitting hole cut in the 3/8" plywood plate.
So now when the opportunity to fill from a fire hydrant presents itself,
the tank can be filled more expeditiously than the three garden noses initially
used.
