Here's a good explanation of ring and wind shake;
http://www.woodcentral.com/shots/shot137.shtml
The following isn't shake but very important
non the less.
This is one you have to watch out for that was
discovered through the failure of new wood
ladders many years ago.
What happens is that a tree is felled and lands
across another trunk. This causes the grain to
"shift" sideways just a small bit, sometimes only
detectable under magnification. This is enough to
seriously impair the integrity of the grain. In a spar
this will be catastophic.

Awesome, thanks for the link. That definitely helps.
All the spruce I have worked seems SO regular that irregularities I assumed would
be easier to see than in some of the low grade stuff I work (for furniture,
nothing structural). But really haven't found any links with many pictures.
I've been working a lot of logs lately, so will start looking for tell tale signs
right after they're felled...
Thanks again!

>From WW's Sunday Papers Volume II - Oil Systems (
http://www.flycorvair.com/hangar1007.html):
*"Oil Recommendations*
The only oil we use in engines today is Shell Rotella T 15W40. It's readily
available and has the highest temp tolerance of any mineral based oil I
know. We use this for break in and normal operation. As an option for
extreme duty or turbo motors, Amsoil synthetic 10W30 oil is my choice. Both
of these are 100% compatible with 100ll fuel."

I want to solicit some advice...
I bought a GN-1 with a C-85-12 back in Sept. It is swinging a metal McCauley 74x41
prop which was on original A65 (all my W&B data, etc. based on A65 with this
prop).
I flew a lot this past weekend. I climb with gusto, but burn a lot of fuel at cruise.
I can spin up to 2500 and do 80 knots. Does that sound right?
BTW, my wing is clipped Cub, so, should get a little more speed, maybe?
Should I re-pitch metal? Try a good wood prop? I worry about W&B if I get wood
prop.
I boought a Piet, so speed not the goal. Fuel burn my aim....decrease it.
Thanks, Scott L. for previous reply. You have similar craft, so value your input.

| Subject: | Simplicity wins... again... |
An absolutely beautiful evening this evening, 5 mph winds, 75 degrees and almost
no clouds. Opportunity was knocking, so I called the wife and warned her not
to expect me home before, ...well, late. I was excited to take the newly completed/go-fast/shiny/full
of electronic gadgets - Sonex/Waiex for a flight
(14 hours on it and counting). Got to the airport- only to find that I'd left
my master and EFIS on and the battery was dead. Sigh... like, not even able
to take a charge dead. Roll over and bury it dead - as my 12 year old says...
So, I was standing there cussing myself because I really wanted to fly - only
to realize that I had a second airplane in the hanger that dead batteries are
just never an issue with. The old trusty Aircamper was sitting there, just waiting
to spread her wings and show up the new young pup.
I pulled out "Part-a-Piet", primed her, flipped the prop and the old A-75 started
on the first blade, putt-putting happily away- dependable as aways.
I put my leather helmet on, and we taxied out to runway 18 in Marshalltown, full
throttle (2500 rpm), and climbed out at about 400 ft per minute. Wow - what
a difference. I've gotten used to the Jab3300 in the Waiex screaming at 3300
rpm, climbing out at 1500+ ft/min. ANR headsets are an absolute requirement.
It took me about 10 minutes of chaffing at the 70mph cruise speed - but then I
started to relax and enjoy it, dropping down to about 500ft AGL. After the second
farmer waived at me - I started checking out the freshly tilled fields and
spent more time looking at the scenary and ignored the guages. I remembered
why I love this type of flying, the absolute simplicity and freedom. It was the
best hour long flight that I've had in a very, very long time.
Keep building boys! You'll never regret your Piet, even if you pick up a new shiny
toy - the old one is still a joy to fly. Mine now has 901 hours and is 27
years old.

Marcus,
I've got a GN-1 with an A-75 in it. It's got a metal McCauley 74x39 on it. WOT
is 2500rpm at around 85mph indicated. Climb is pretty good. I typically cruise
at about 2250 rpm, burn at that rate is around 4.5 - 5 gallon per hour, speed
around 75mph.
Your cruise of 80 kts (92mph) seams a little fast to me - but I guess it is possible.
I'm not really comfortable in my plane at 90+mph though, it buffets me
around too much.

Great story, Lorin. Brought back memories of the years I flew hot air

freshly planted farm fields, the people looking up, smiling, and waving --
low and slow is good for the soul. My best, Ken
