| Subject: | Re: Change of business model . . . |
Bob,
This is a very interesting development. I expect this thread to go on for a while....
I work in distribution/sales for industrial automation. Occasionally we find ourselves
in a situation where a standard product does not fit the customer need,
so we'll design a little kit or combine some products and accessories together
to meet the customers' needs. Usually those are one-off events; however,
we sometimes find ourselves in non-ideal situations. Example 1: the customer
either buys one or two every year for many years; small batch builds not being
very profitable. Example 2: the customer buys many 10s or 100s and we find ourselves
building kits more than selling new stuff.
Your situation in some ways reminds me of those challenges.
I just visited aeroelectric.com and could not find a listing of these items. I
thought it might be under "Catalog of Products and Services", but I only see
your publications there along with another note about the sale of the business.
Is there a list / catalog of your many "solutions"?
Regarding the business sale.... do you want to sell the designs as a "lot", license
the designs to a third party, license some designs and still manufacture
some designs and only outsource distribution, etc, etc?
Perhaps you're waiting to see what the post/pronouncement brings...
I don't think I am the right man for the job, but I though fleshing out the discussion
a bit would be beneficial for all.
Regards,
Jim

So, what is the way to mount engine pressure senders not cantilevered?

Most of us probably know this, but cantilever mounted engine pressure
senders is bad practice, steel or brass. I have personally seen steel
ones break.

Hi Werner
Well, that one I know, I've used it in the RV-9A and also the -10, but the
senders are also cantilever mounted in the T bar ... I know that the T bar
will not shake as the engine itself, but there are also cantilevered, and
can break as well

Hi Carlos
Obviously they have to be installed cantilevered, just don't mount them to t
he vibrating engine.
Remote mount them with a block like this Aircraft spruce part, 04-00318, mou
nted on the firewall, run -3 hose to it with a restrictor fitting at the eng
ine to restrict flow if there is a hose failure or fire. This for oil and fu
el pressure.

Carlos, mine are vertical so much different scenario, and the vibration
level is magnitudes less then directly on the engine housing. You could
mount it on the hose only and then fix the sensor by a clamp around the
sensor housing that is the least stress on them.
Cheers Werner

I put a large adel clamp around my oil pressure sender, actually two of
them. Then those adel clamps are bolted to smaller clamps that go around
two nearby engine mount tubes. As I understand the term cantilevered, I
would say that mine is not.

Carlos,
You can see how I did it at: http://www.europaowners.org/main.php?g2_itemId=67636
The first 11 pictures show how I did a remote mount of the oil pressure sender.

| Subject: | Re: IVO Prop current limiter |
Hey guys,
I built Bob's current limiter for my IVO prop. My first attempt at it did not
work. It seemed to have an issue similar to that reported by Mike Welch some
time ago. As soon as I hit the switch in either direction, the motor would
turn very briefly, then the yellow light would come on.
I could not figure out where I'd gone wrong, so I built a new circuit from scratch.
My second attempt seems to work properly, although I'm still building and
my prop is not assembled. With the second circuit, the motor turns normally
in both directions. To test the cut-off, I shorted the leads that would normally
go to the motor. In that configuration, the yellow LED immediately turns
on, and the breaker does not trip.
It will be a little while before I can test it with the propeller assembled.
Bob, this is such a terrific addition to the IVO IFA prop. I greatly appreciate
you designing this and making it available. Thanks also to Dennis for his
involvement in making it happen.

Hi Werner, with respect, it is NOT a much different scenario. Its orientatio
n makes no difference, it's a cantilevered mounted sensor no matter where or
how you mount it. It's the mass vibrating on the end of the threaded fittin
g that may cause the failure.
If you support it like suggested with an Adel clamp that may work, but the c
orrect fix (and good practice) is to remote mount it somewhere other than on
the engine.

Send me your assembly and let me stroke it
on the bench with a 'scope attached. This
is one of several products I'm hoping will
come to the market after the new AeroElectric
'team' is assembled. I've had offers to
discuss options from several people. In
the mean time, we need to see if a fine-tuning
of circuit constants is called for.

| Subject: | Connectors and factories |
Bob,
As someone who runs a small electronics factory I can sympathize with
your decision not to continue doing that. There are a thousand trivial
things you have to do every day that impact your bottom line, your
ability to sleep well, and in the OBAM business, more serious consequences.
I'm building a CH750 and just this week have been pondering the problem
mentioned with the Ray Allen trim servo wires. There are other
disassembly points too like lights and gauge senders in the wing, so I
would like to choose one type and stick to it. Maybe we can kick this
around for a bit.
While I would like to use a standard connector, preferably mil standard
like the old MIL-DTL-5015 ("MS connector") they are just too bulky and
heavy. I really would rather not use a proprietary sole-source connector
like the Switchcraft EN but if I'm going to choose something sole source
I would want one that's in common use.
I'm considering two connector families. One is weatherproof automotive
connectors like the Delphi Weather Pack. The other is a lightweight
plastic variant of a military round connector, like the AMP CPC series.
Weather Pack is available in 1 to 6 and 22 contacts, and seems to be a
well proven system, but seems a little bulky.
Comments?

Tim,
mine are mounted remote on the Firewall (which indirectly is written in
my posting (vibration level.....)), directly on the engine IS a bad idea.
