| Subject: | Re: Hydraulic Lock Prevention |
Hi all,
for those who prefer a purely mechanical oil shutoff system let me share my actual
setup on the 18 T : Basically the fuel tap is linked by push-pull rod to a
common 3/4" ball valve on the right side of the firewall where the oil hose from
the tank forms a U-turn. So in the cockpit you will not forget to open or
close the systems or otherwise it would not be of dramatic consequence. After
warnings from this forum that in case of a broken mag ground wire you only have
one way to kill the engine by closing the fuel tap and too much time would pass
with the oil shut off till the engine actually stops I reworked my initial
concept :
The version 2.0 has an extra lever on top of the real oil valve lever and in
normal mode both move united when you open or shut fuel and oil. In the unlikely
case of a broken earth wire the oil lever can be unhooked via Bowden wire in
the cockpit near the fuel tap and oil supply remains open while you kill the
engine by fuel starvation.
So this set has worked great in the past and dont worry about the rubber diaphragm
in the carb falling dry, a year inactivity (Russian FLA reg aftermath) had
no effect on it. Certainly no hydraulic lock since but we always pull several
blades as ever. We get half a cup of oil in the plastic bottle on the ex pipe
that collects from within the crankcase and thats it.
Fitting an electric shutoff valve to the underside of the oil tank is a poor
idea, it could be placed anywhere, just where my ball valve sits would work quite
as well - and is easier accessible. But then, this is an electrical design
- and electric current is a weird material ........
Cheers
Vic

Sam, Dave, Keith, et al;
Who am I kidding, other than myself! I am totally addicted to the list and
can't quit! One on one I get along fine with people but obviously have no
communication skills whatever with a keyboard and keep getting into trouble.
Will try to do better.
Thanks;
Walt

Now, wait a minute Walt...
You and a few others are very knowledgeable and bring serious value to this
List - I appeal to you to reconsider refraining from further contributing to
this List.
I believe Pappy's comments regarding the limitation of E-mails in conveying
the true spirit and intention of the text is very true. The lack of voice
tone and eye contact is one of the major shortcomings of the E-mail concept
making it very easy to miss the intention (tonality, if you will) of the
written text.
This has happened to me too, several times, both in sending a message that
was misunderstood and misunderstanding a message sent to me...
In reading this evening's latest posts, it is obvious to me at least, that
there was no ill intent with neither one of you - let's agree to continue to
operate within the limitation of the e-mail system and continue to
contribute - we need you and others like you to stay and help the rest of
us, especially newbies who both you and I once were...
I hope you will consider the above,

Keith;
Just saw all the reaction to my post. I only see email in the AM and after
work - no I phone or anything like that.
I took your comments to mean you were in fact telling me to use another
process. If that was not the case then you have my apology.
You are right - no one dares post here and I usually refrain from posting
professional advice precisely because of that reaction.
I will not be offering any in future.
Walt

Walt,
I addressed a post to you and was thanking you for your tips. I did not mean
to tell you to invest in a different drilling process. Instead that comment
about drill bits was intended for the general audience. I should have made
that clear. A guy that hasn't done a million canopies may want to use the
method LP Aero suggest. I did and had excellent results. I have no doubt
your method meets or exceeds that standard. It's no wonder nobody dares post
on this site.
Sorry if I hurt your feelings.
Keith
