--> Zenith-List message posted by: "John" <jlifer@bellsouth.net>
I would be very hesitant about using the Cortec primer under my finish coat. I
sprayed parts LAST YEAR and they are still very sticky. Humidity is the problem,
during the winter they were OK, now with it hot they will adhere to anything.
Bits of shavings stick like glue. I won't be using any more of it especially
on the outside.

Have build a new gas tank. Is Pro Seal used on the mating surfaces before
riveting to help seal the seams? Which Pop rivets would be best. Know that
a solid shank is necessary but there are lots of different types.

Richard,
Congratulations, and hope all goes well. Do keep us informed when you
begin flight.
We've not been priveleged to hear much of the performance from the RAMs
engines.
Good luck,

| Subject: | IFR requirements |
--> Zenith-List message posted by: "Frank L Laczko" <frank@laczko.com>
Just to add my 2 cents to the equipment requirements
for legal IFR. Several people quoted the following:
"This requirement is
found in Part 91.205(d), by way of the following
statement:
"Two-way radio communications system and navigational
equipment
appropriate to the ground
facilities to be used."
While on first reading this would appear to mandate a VOR
receiver, I do not read it that way. Note that the
requirement is to have equipment "appropriate to the ground
facilities used". If you do not use a VOR for navigation,
you should not need the equipment. There is no statement
anywhere that you NEED to use ground based navigational
equipment. Theoretically at least, you "could" fly with only
an approach certified GPS system into airports that have a
GPS only approach.
That said, in practical life I would WANT to have a
VOR/ILS/GS receiver.

--> Zenith-List message posted by: "Pete Krotje" <pkrotje@athenet.net>
Bill,
I think you need a bit more testing to narrow the range of possibilities.
1. What prop do you have
2. What altitude & rpm when problem occurs
3. What are EGT readings when problem occurs
4. What are EGT when carb heat applied
5. What are EGT when no carb heat but throttle retarded just enough to
smooth out engine
6. Is the new carb economy tuning kit installed?
7. What is most rpm available full throttle level flight
8 What rpm when full throttle on take off roll
It appears that at full throttle your engine is running too lean since
application of carb heat will richen the mixture. Mixture is controlled by
a combination of altitude, prop load, and airframe drag (as it contributes
to prop load). There are a few adjustments you can make to the carb to
adjust for different prop loadings. If we can get some numbers we can make
adjustments to bring the carb tuning into line with your airframe & prop
loadings.
Pete

Bill...It still sounds like you either have problems with those vent
lines, or, as was mentioned, a problem with the altitude compensating
portion of the carb/carbs. The vent lines provide a reference pressure
for the diaphragms in that altitude compensating section of the carbs.
Are the vent lines hanging free, or do they attach to your air intake
box, as I think you mentioned before? If they attach to the air intake
box, then changing from no carb heat to carb heat would likely change
the pressure in the intake box, which would be sensed by these lines and
cause a change in the amount that the throttle/mixture opens.
If you're going to be at the airport Saturday I could meet you there to
help take a look. I have the Bing manuals for my carbs, which I'm
guessing are the same as yours. I've taken the diaphragm portion of
mine apart several times in order to change the main jet needle
position. We can take a look at yours if you like?

Dear Thread, yesterday several possible solutions to the running rough
at higher altitudes were offered. The easiest advise was a possible vent
line off the carburetor. I remembered that I had connected a hose to the
mechanical fuel pump and thought it might be a miss routing, but I went
to the hanger tonight and it is not that. The vent lines are correct
and clear sooooo it must be something else. The key has to involve the
fact that she smoothed out immediately when I applied carb heat and
returned rough as soon as I pushed it back in.
I checked the fuel tank vents and they are free. I rechecked the air
filter and hoses clear and correct. I spoke with another builder (much
smarter and abler than I) and his response was that that it sounded
like the malfunction was in the automatic pressure compensator built
into the Bing carb. I'm pretty sure I have one of those cause Pete said
I do. If that is the problem how do I get it repaired? Who out there in
builder land knows ? Pete, is the carburetor still under warranty? If it
is, do I just take it off and send to you? I am really reluctant to try
to fly it again knowing that the carb is malfunctioning. Seems like a
fine way to spill good gas on the grass ! Hope to hear from someone with
a good idea, Best regards, Bill of Georgia

Hi Bob,
I'm no expert on this stuff, just helped a friend build his RV tanks with Pro-seal
and decided that I would attempt it. Yes, he placed pro-seal between the matting
services and then riveted with solid rivets. I plan on using the same system,
I made an edge 20mm that my squeezer could manuever around for the solid
rivets.

This would be true about pulling the carb heat on and causing a richer
mixture due to the heated air being thinner, but so would climbing in
altitude cause a richening, which is why we have to lean the engines
more and more with altitude gain. So, if the engine were already
running lean it should run better with a gain of altitude. Sounds like
Bill has the opposite problem.

Bill,
Applying carb heat in flight would certainly result in smoother running
if you had been too lean which, as you said in your previous post,
would seem to be likely since you had put in a higher
performance air filter. Have you rejected this hypothesis for some
reason? Have you tried enriching the mixture with the adjustment on the
carb? Has Pete responded?
Solving this will be helpful for all us Jab drivers considering a higher
performance filter.

I am riveting my tanks also. Here is a site that was very helpful.
http://www.krnet.org/wingtank/ Also check out the EAA website for fuel tank construction. I bought my rivets from McMaster-Carr, P/N 97524A020, closed-end sealing blind rivets. I'm ordering my Pro-Seal today from A/S, very expensive, I haven't been able to find substitute.

Johann, unfortunately I think you have some warped heads there. I
spoke to a Rotax agent I know very well and it's a sure indication of
overheating of the heads when they leak in the place you mention.
There is a hardness test you can do on the aluminum to verify it but
you're into a major expense to replace those.

Hello all list members.
I thank you all, Greg, Trevor, Paul and Gary for your help and input.
After a long sleepless night and $ worries for buying four new heads, I took the
head and cylinder off the engine for a closer inspection.
It looked like the oil was seeping through from the O ring around the cylinder
closest to the crankcase and seeping through the studs M8 where it leaked between
the cyl and head.
When inspecting the O ring on the cylinder it was flat and not round as it is supposed
to be.
I just ordered new rings from Lockwood and will let you know how it turns out.
Thanks again.

| Subject: | Fuel vent dumping on LE HDS tanks |
--> Zenith-List message posted by: "Paul Hartl" <paulhartl@cox.net>
Hi List,
After my 4th flight in N414PZ I was trying to determine where all the
fuel is going - too rich of mixture, leaking tanks, etc., when I noticed that
a rather slight jostling of the wing (when parked) sent a fair amount of fuel
out the vent, even with a tank only 1/3 full! There is a kind of resonate
condition that builds waves of fuel rather quickly inside these tanks, and
it doesn't take much shakin' to get a a pretty good stream out the vent.
I also noticed marks under the wings aft of the vent, clearly tracing out
where dumped fuel had been pushed back and up onto the lower wing
surface during flight. At $3.20 a gallon, this is getting expensive!
These are the ZAC-built leading edge 10-gallon tanks for the HDS. I have
cut the vent at a 45-degree angle to get a little ram air pressure in flight, but
I really wonder how much fuel is being dumped in taxi operations and when
in turns.
I'm thinking about modifying the vent to look more like a pitot tube - or
perhaps add some sort of baffling inside ?????
Has anyone noticed and/or addressed this issue?
Thanks,
Paul
P.S. N414PZ really is a nice flying machine. I now have 3.2 hours on her. --

Bob,
Pro-Seal is the correct stuff to use. I used Cherry Q rivets to hold it all
together. They are self plugging but I still dipped each one in Pro-Seal
and put a smear of the stuff over the head of each rivet once it was in
place. There are some pictures and notes of what I did on my website at:

Paul,
I made my tanks, but the vents should extend up to within half an inch
of the top outboard corner of the
tank. I've never experienced any overflow, surge splashover with
exception of filling above the overflow
once on my header tank. You should look inside with a mirror and
determine where your overflow tubes end.
Perhaps that would help you understand what's going on. I've wobbled my
plane to see the same, but
never gasoline sloshed leakage.

Does anyone know if the new blue colored silicone hose can be used for fuel lines.
It's listed in the new Spruce Parts catalog page 122 lower right (silicone
Hose)
Thanks in advance.

| Subject: | Drilling Metal Minimum RPM |
--> Zenith-List message posted by: William Dominguez <bill_dom@yahoo.com>
Im looking to buy an electric cordless drill and
would like to know what is the minimum recommended RPM
for drilling metal. So far Ive been doing my drilling
with an AC electric drill that does a superb job, but
this one turns at 3000 RPM and I have not found a
cordless drill that goes that fast. My problem with my
AC electric drill is that the distance between the
handle and the bit point is too long for proper
control.
Thanks

I interpreted the original post to imply that the altitude
compensation device was working properly for the original air filter.
I don't know how the carburetor's altitude compensation device
actually functions, but if it was initially set for the lesser airflow
of the original filter, I thought it might be possible to enrich its
setpoint for the higher airflow.
Maybe a dumb idea.

No - silicon is not compatible with petroleum fuels. Alcohol yes, gasoline,
no.

Yes it can, I used it for a sight glass tube, it got hard and discolored in
about a year, but it still worked. It's soft and easily cut, so be careful
where you put it. The line I used and it came with my PegaStol wings is
called poly line (I think). You can find the same line at Lowe's for $.13 a
foot. Before anyone says anything, it is the same line.

I don't think speed is a terribly important quality for a drill. My
own preference is for a 9.6 volt drill I found at Sears because it
feels so good in my hand with it's rubber handle pads.
There are lots of folks that say the slower drill speeds means more
deburring. Even if they are right, I say you need to deburr
anyway. Considering the amount of time we spend drilling holes I
think it is better to worry about how comfortable the process is than
how perfect the holes are before deburring.
I suspect any drill that makes holes is satisfactory from the
airworthiness point of view.

G'Day List,
A guy here in Aus converted the ailerons of a HDS to flaperons & turned the
bottom Zee spar back the other way so as to get more down flaperon
I believe the stall rate came down by about 6 kts.

I just read an article in the December 2004 issue of KitPlanes that
recommends a drill capable of about 1500 RPM or higher. My Makita cordless
drill runs at 1300 RPM and did a good job.

are there some photos/plans of this mod available??
I was thinking about making flaperons, but that mechanism seems to be weak
point and probably I will go on with normal flaps.
Where he installed flaperons mechanism? Could You provide some more info?
Thanks
