3-blade prop?

I don't remember if you said you had a lightweight PM starter on your bird,
Jay. If not and you put one on, that would offset the increased weight on the nose
with a 3-bladed prop.

Yeah, we've got the lightweight starter, so we're good there.

As far as any loss in useful load, I won't notice 11 pounds on 1460.
The W&B might be an issue though -- Atlas is already a bit nose-heavy.
Nothing a toolbox in the luggage compartment doesn't cure, though.
(And when we've got four on board, all is good.)

Anyone got any experience with CS props going bad? The oil on the
windshield was minimal, and there was only slight evidence of oil on
one blade. Is this something that could:

a) Stay the same over time
b) Get worse little by little
c) Let loose all at once

Also, can anyone recommend a good prop shop?

Yes, or even get better.

Probably not, but of course you should have it all
inspected by your A&P, or just take off the spinner
and have a look yourself to see if its even coming
from the prop/hub.

A small amount of oil on the windscreen now and
then does happen, especially when weather temp
changes a lot. And, it may not be coming from the
prop. You'd be suprised at just how such a very small
amount of oil can get slung around by the prop and
get on the windscreen.

A friends O-360-A1A started misting his windshield. I think it turned out
to be from a front bearing on the engine.

When mine did it, it turned out to be the prop governor had sprung a
leak, and was intermittently spraying a stream of oil at the prop.

Is it oil or grease? Some people overgrease the
Hartzell props during maintenance and it slings a bit.
The older Hartzell diaphram props will also leak a bit
before the diaphram goes worse.

As for prop shops, I have had good luck with Sensenich
in Lancaster (they will also work on Hartzells) and
H&H propeller I believe is the other shop. I'd stay
away from the Hartzell factory shop in Piqua at all costs.

The Hartzell constant speed prop on my Husky blew a grease seal and
grease covered my front wind so completely I had to look out the side
to land. It was a bit scary. The prop didn't need a complete rebuild
but needed to have the seals re-done.

Well, we thought it was oil, at first, because of the streaking, but
when we looked closer at the "bugs" on our windshield, they looked like
tiny little flecks of grease.

There was a trace of oily coating on the back side of one of the prop
blades, which we *thought* was oil, but I suppose it could be greasy
residue, flung under centrifugal force? Dunno.

My A&P did grease the prop hub at our last annual, and the weather has
been pretty hot ever since. This leak appeared (I guess not
surprisingly) on a flight after our first "cold snap" of the year.

I've spoken with my mechanic, and he advised that we clean it up and
watch it closely, but take no action at this time.

Last year when we had grease leaking from one of our props, Maxwell
http://hcsweb.com/maxwell/ in Minneapolis was adimit about regreasing it
with a thicker grease than had previously been used. I think they went from
Aeroshell 6 to Aeroshell 5 because they've seen 6 ooze past the seals in hot
weather. Anyway, they had a pretty strong opinion about it and they're well
known as one of the best prop shops in the Midwest. They were also pretty
adimit about not over greasing the props. Infact Hartzell even changed
their recommended practices to specify that you only add up to a maximum of
one ounce of grease or until it flows freely from the open zirk opening,
which ever comes first.

Give Maxwell a call. Paul's Prop Delivery Service ships props at great
rates and with great care!

I might even have that old prop-pillow around here someplace, still. g

BTW, Crystal Airport (MIC) is in a little developer/Mayor/neighbors bind
these days. Maybe Maxwell can join Bolduc, over at ANE, if things end up
going south for MIC.

Crystal Airport (MIC) is 8 nm SW of (ANE) Anoka County-Blaine Airport.

I had that problem when I first got my PA-24-260. The leak was actually
from the prop governor, not the prop. On my IO-540, the mount point is
on the left front just inside the cowl opening. Oil would come out (by
buffeting?) and mist the windshield lightly and also run back under the
cowl and streak out the oil filler. It was so slow that it would take
several flights to get the oil door if I cleaned under the cowl.

I found most of the leaking happened between flights, so I started wiping
off the control arm before flying and one time I pushed on the rotating
part and it popped in and "seated" and it quit leaking!
