Now, that makes much more sense. I also thought about the hole enlargement;
but, that doesn't seem to be happening. I did get the rubbing as in the
original request on this thread when I tried tightening the bolt down on the
bushing. That went away when I went with the method I used. Thanks for the
input!

I have a picture of my installation on my engine mount through the
firewall access door.
http://www.mstewart.net/michael/rv/
under the 6A/systems/electrical/ramp jump
1300 hrs. of flying her. Never used it. Super 8 will NOT have it.
That said, my firewall has the master relay(always hot on one side)
mounted on the right side under the oil door and I have put jumpers down
there for various reasons to check voltage, or get live voltage, or
what ever on many occasions.

Fellow listers,
I'm thinking about mounting a battery charger connector on my firewall
so that I can keep my battery charged as my AM/FM radio draws some
current to keep the stations/clock....
I'm trying to determine what area on the firewall can be reached through
the oil filler door so I can mount this thing before I close the forward
top skin and work on my canopy
Does anyone have a general idea of what can be reached? I'm hoping for
an area above and to the right/left of where Van's firewall forward
instructions tell you to put the brake fluid reservior.
Thanks,
Ralph Capen

I too and a small amount of binding when I tightened
the bolt, but I found that the binding tended to be in
certain spots. By trial and error I rotated the
bushing a bit & tightened the bolt, and was able to
find a spot that was completely free of binding
throughout the range of bellcrank travel.
Incidentally, my bushings did not fit freely into the
bellcrank weldments out of the box. I think the tubes
were slightly distorted from the welds of the arms,
and also hardened in those areas so they weren't
reamed perfectly smooth from the factory. I had to
spend quite a bit of time "massaging" the bushings and
the inside of the bellcrank tubes, until the bushing
rotated freely and smoothly inside the bellcrank.

Can some one here that knows a lot about these engines contact me off list about
a non aircraft application? I want to mount a large hydraulic pump to one.
I need about 250 HP at around 3600 RPM to spin this pump. The pump has an SAE
C Mounting flange that conforms to the SAE J744 standard. Thanks in advance.

--> RV-List message posted by: "Terry Watson" <terry@tcwatson.com>
This is interesting! Two or three years ago, I asked one of Lightspeed's
reps at the Washington State Aviation Conference if the cord could be put on
the right, and got a "No, of course not." or similar response. It was the
only negative experience I have had with Lightspeed, but it was enough to
leave a bad taste. They considered their headsets the ideal choice for
RV-4's and 8's, but didn't give a damn about whether we had to climb over
the cord and wrap it around behind us or not. Glad to see they figured out
what at least some of their customers need. I'll see if I can get them to
switch mine.

0.5 MIME_BOUND_NEXTPART Spam tool pattern in MIME boundary
--> RV-List message posted by: dmedema@att.net
I continue to have high CHTs, especially on climbout.
I went flying this morning with OAT about 80. At 3000' in
a stabilized cruise with no leaning, I saw the following numbers
for EGTs & CHTs:
Cyl 1 1280 372
Cyl 2 1269 365
Cyl 3 1300 391
Cyl 4 1295 361
Oil temp was 195.
Data taken at 2240 RPM.
The EGTs seem low if anything and the oil temperature certainly
isn't real hot. The CHTs just seem too high and cylinder 3 can
easily climb to 430+ on climbout at which point I throttle back
to stop the climb in temperature. I have a small baffle in front
of cylinder 1 and cylinders 1 & 3 are very close during climbout
despite the 19 degree difference in cruise. I built a plenum
but never put the permatex around the baffle/engine line. I'm
going to do that real soon. It seems like I should be getting 50
degrees cooler from my setup. Can the permatex make that
much difference? Anybody have experience before and after
using caulking on their baffling?
(BTW, I calibrated my CHT sensors against a candy thermometer
at about 400 degrees and they were easily within 5 degrees of each
other.)
Thanks in advance.

I started this thread and now that I have seen all the responses I think I
have it down pat. Amazing how much feedback a seemingly simple plea can
evoke!
I actually ended up passing a .375 drill through the bell crank before the
.375 bushing would slide in freely. I too think the welding caused some
high spots on the interior of the bell crank.
Moving on now! Thanks to everyone.

| Subject: | Brake pedal finish |
--> RV-List message posted by: "Cammie Patch" <cammie@sunvalley.net>
After constructing my brake pedals (and priming each part) I thought about
what kind of finish to put on them. I flew a 182 the other day and noticed
that it's painted pedals were worn thru to the aluminum, so I didn't want to
go the paint route. Anodizing sounded cool, but the primer was already
on.....
So, I took the pedals to a local Ameriguard store (like Rhino Lining) and
had him spray a black truck bed liner coating on them. I taped off the sides
so it won't interfere with the rudder assembly, then painted the sides
black. They look awesome! Now that the rudder/brake assembly is done, I'm
thinking about storing it on the living room wall. :-)
I tried to upload a picture, but it wouldn't go thru. I can email a pic to
anyone who is interested.

I have an O-320 with a Sensenich prop. I also have about the same Cyl temps
with #3being the hottest at 390 in cruise and will hit 450 on climb. I had a
very tight plenum and took it off but had no effect on the cht's. My oil
temp is also cold and I put a flap to close it off and still only see 210 on
the hottest days with the flap closed. I spoke to Lycomming at SNF and they
said its fine, go fly and forget it. I have about 180 degree spread on egt
at cruise and 50 degree on cht. I'm not happy about it but have no answers
as of yet.

Jeff,
I like the your basic idea but, if I'm reading your message correctly,
the implementation bothers me on several counts. First, it appears that
you have an unprotected male connector that could easily short your
battery if it inadvertently touches a ground. Second, it would be very
easy to get the polarity reversed from the charger. And three, I sure
don't want to be around when someone mistakes it for an engine
pre-heater and connects it to 110 v. 8>)
I'd recommend using a connector that is protected from accidental
shorting, can't be reversed and doesn't look like a 110v plug. Also, I'd
put a fuse somewhere in the wire, probably close to the battery connection.
