Hello all,=0AThanks a lot for your information.=0AThe plans shown=C2- 1/4
diameter pipe for the standard header tank, I think it would be enough. It
=C2=B4s easy to get finger screen and weldable flange for this size. I=C2
=B4m going to use .032" sheet as per your instructions.=0AMy Best Regards

st: CH601HD Wing tanks=0A =0A=0AHI Marcos,=0AYou=99ll be better off
using 3/8 O.D.- .035 wall 3000 series aluminum fuel line. The 3/8 line has
been nearly a requirement in aviation for a long time. =C2-Select only a
fuel valve that allows left, right or off. =0A6061 T6 is also easily by TIG
process.=C2- 5052 is selected for deep formed products that=C2- need t
o stretch.=C2-=C2- 6061 is very corrosion resistant and suitable for ta
nk material.=0ATry to get something like an Andair fuel valve, with left ri
ght and off, see FS20 valves at Aircraft Spruce. =0A=C2-=0ALarry McFarlan

nd all,=0A=C2-I=C2=B4m clear now. I have also a =C2-.032" 6061T6 sheet
(I have to bought one only for rear spars and small pieces but is 12 x 4 ft
)=0AAnother question as I=C2=B4m prepairing the order to Spruce, the select
or valve must switch between right and left tank only or right-left and bot
h? I want to use aluminium fuel line of 1/4", It=C2=B4s ok? My engine is a

: CH601HD Wing tanks=0A=0A=0AHi Marcos,=0AYes, there are no holding points
or fasteners per se, but the fit has to be such that the nose skin, spar bu
mpers only contact the cork that gets wrapped=0AAround the tank.=C2- The
tank should fit like a glove and it will not move about at all after the no
se skin is formally clecoed or riveted in place. =0A.040 is a bit heavier t
han I=99d use for wing tanks.=C2- .040 would weld fine, but it
=99d be 25% heavier than it should be and not improved for strength or d
urability.=0ANot so sure of the tank length, but the clearance was approxim
ately =C2=BD inch tank end to rib each end.=C2- =0A=C2-=0AThe first hal

s=0A=C2-=0AHello Larry=C2-and all,=0AThanks a lot for your help, I=C2
=B4ve studied your web several times..... Great job with a lot of useful in
formation.=0AI have an idea of what I need but just some points of doubt:
=0A- I understood thast there is no fixing points, just the cork and the wi
ng skin around it?=0A- What about the angles on the rear (between tank and
spar) Is only to separate a little, no rivets or screws=C2-to attach the
tank?=0A- How long is the tank and how much separate from the first rib?=0A
=C2-=0AI read about using 5052 aluminium sheet, but I have a lot of 6061T
6 sheet of .040 but i=C2=B4m not sure if this is weldable.=0AThanks in adva

013 15:50=0AAsunto: RE: Zenith601-List: CH601HD Wing tanks=0A=C2-=0AHi Ma
rcos,=0AI built tanks within my wing leading edges. It was and interesting
process. The process is documented in Section 2 of my journal and in subjec
ts of =0Aconstruct in the site menu called =9Clead edge tanks
=9D. See my website at macsmachine.com. The pictures show tools, jigs and s
ome of the=0Amethods which enabled fitting, jigging and welding the ends, b
ack and nose skins.=C2- I=99d recommend you use .032 minimum materi
al if you are welding these.=0AYou could=C2- possibly do without the draw
ings if you look very carefully at what was done on my site and template ta
nk ribs 1/8 inch smaller than the wing=0Aribs and shorter by the depth of s
par bumpers.=C2- Also, it=99s not hard to make a set of filler caps
that go flush with the wing skin if you study what was done on my site.=0A
I will say that the constant chord non-tapered wing should make the job muc
h easier than what I had to do with the HDS.=0Ahttp://www.macsmachine.com/h

om=0ASubject: Zenith601-List: CH601HD Wing tanks=0A=C2-=0AHello all,=0AI
=C2=B4m started to build the wing spars, left spar=C2-is riveted and righ
t one=C2-in proccess. I want to install wing tanks but my plans (Serial 8
487) has not information about that.=0AI want to build my own tanks in 5052
aluminium sheet but I have no idea how to support them in the wing spars.
The only information I get are some pictures from HDS wings and I think I h
ave to move the ribs to allow space for the tanks.=0AAny information, photo
s, etc...?=0A=C2-=0AMarcos Varela=0ASPAIN=0A=C2-=0A=C2-=0A=C2-=0Aht
