Wayne,
I agree that your life and health are worth what you paid for the unit.
As you also said, a bit pricey for one Rebel though.
I looked at several displays at Oshkosh and it seems like it is going to
take $400-500 US for a commercial unit. From listening to the high pitch
whine of the units being demonstrated at Oshkosh, I have thought about
buying a shop vacuum and using it for the air source. The way the motors
sounded I'm not certain that the pump in the store bought unit isn't from
a shop vac.
There is a fellow that is a member of my local EAA chapter that made a
unit from the smog pump from an old automobile. I haven't been able to
talk with him to get the details of his design. After I gather the facts
I will decide which way to go.
Also, wanted to say thanks on the advice to build a jig for the
flaperons. I read your message to me and then struggled with whether it
would be worth the time to build a jig for 4 parts that aren't that
complex. I built the jig and with 1 done and the 2nd part jigged and
ready to go, I realized that it was worth the time for repeatability
without a lot of hassle.
Thanks again for all the wisdom shared,
Terry McClary

Terry, considering I am continually working with these "great"
isocynate
ladden products, I purchased a commercial unit 2 years ago that will
supply
3 workers on 50 foot hoses (2 on 100 foot). Wasn't cheap at
approximately
$3800 Cdn. complete with 2 hoods and 2 x 50' hoses, but I tend to
think my
life is worth at least that much! (this unit is definitely overkill
for
building a single Rebel, but something similar should be used if
also
building a set of floats, due to the extended time you will be using
either
proseal or my favorite Sikaflex 1A. during their construction)
I'm sure you could make your own with a quality vane pump and good
micron
filters on the inlet and outlets. IF anyone is interested in the CFM
etc of
my unit just ask and I will dig out the paperwork for the unit. Mine
uses an
adjustable "dump" pressure valve to relieve the excess air flow. One
worker
needs 9 to 11 psi at the hose connector manifold and 13 to 15 psi
for two
people.

Wayne,
Did you make your fresh air system or buy one of the commercial
units?
