Hi Jerb,
I will still use the manual pull gun on the wing rib fabric rivets. You have
to be careful with it also when doing these rivets because as you mentioned,
the head of the gun will slide off the rivet when pulled and rip a nice hole
in the fabric. Ask me how I know this. The patch is not noticeable if you
don't know it's there because it is under the finish tape. The pneumatic gun
is a big time saver though on the stainless rivets, especially the areas
where there are bunches of them and I wouldn't build another Kolb without
one---unless I had to.
Later,
John Cooley

Pneumatic rivet pullers are available from Harbor Freight or Norther Tool &
Hydraulic. Harbor Freight usually has the best price on them. Just had
them on sale..... I did find on our FireFly when install the wing fabric
rivets there is a tendency for the tip to slide across the fabric with the
sharp mandrel of the just pulled rivet. Don't use to much pressure and
proceed with care.

I used a hand powered rivet tool on all the rivets on my MKIII it did take a
bit more time and effort but I found out something that you will not notice
with the air riveter. There is some small percentage (around 1%) of rivets
that will pop early so that it will not have 100% rated holding power. When
this happened I drilled and replaced the rivet. Maybe that's why Homer
specified so many rivets in high stress areas or maybe they are all needed
at 100%. I didn't want to find out.
Food for thought

Kolbers, I was formerly a tool addict, had to buy at least one a week.
Been on the wagon for a few years now but not unhappy about most
of my accumulation. Could never figure why a sane person would toss
away $50 on a restaurant meal but begrudge the same amount for some-
thing that he could use over and over. (soapbox kicked out from under me)
Just got a new Harbor Freight flyer that offers a "laser picture hanger
level"
Don't know if this could be used for prop setting???? I bought a cheapo
Radio Shack laser pointer to do the same thing and so far haven't tried
it.......setting the blades with my old swinging prop protractor seems to
do well enough. The Harbor Freight gizmo goes for $9.99 , whatadeal!!!

Jack,
Thanks for the info. I guess I had heard of it as the Simonini. How's
the cost compared to Rotax? Do you know if reliability and 600 hour
TBOs are showing up as realistic in real world? That's a good deal
more HP out of a smaller displacement than the Rotax 447, which I know
is do-able, but then to also claim higher TBO, I was wondering if they
claim any reasoning for the longer reliabilty. This especially tru when
considering that the single cylinder Victor1 has a piston going twice
as fast as pistons in a similar rpm, 2 cyl Rotax.

John R, and interested Kolb Friends -
I also interpreted FAR 91.1 to say "Thou shal have a flight manual in order
to be certified for day-VFR." (among all the other things)
And it was the full-up, N-certified status I wanted, so I wrote my own. And
it was fun, too!
I loosely followed the format of a mid-60s Cessna 150.
I would work on it a bit during lunchtimes in the office, and it was done
quicker than I expected. It's easy to write if you built the airplane -
various aircraft systems' descriptions will come roiling off your brain WAY
faster than you can type!
Here are the primary topics I included in my POH:
1. Description (gen description, dimensions, weights, engine, prop, elec
system, etc.)
2. Normal Operating Procedures (wing-fold steps, preflight, flight
procedures, etc.)
3. Emergency Procedures (what to do if xxx fails, a few scenarios)
4. Flight Characteristics (takeoff data, climb, cruise performance,
landing data)
5. Operating Limitations (Weight & Balance, and CG/loading data)
Appendix: Diagrams (instr panel; oil, fuel, elec & pitot-static systems
diagrams, etc.)
Presently, I am still collecting data to insert in Sec 4.
(Will get those numbers as my flights accumulate.)

What is the RPM of that engine? Unless it is turning twice as fast, the
piston is moving the same speed as the 2-cylinder.
They are probably making most of the extra power through the better
volumetric efficiency provided by the liquid cooling. That just means that
the air getting to the combustion chamber is cooler and more dense. So it
expands more when the engine fires.
Also, a more accurate TBO for the 447 would be about 600 hours, so the 600
hours is not that unbelievable. The only reason that a 447 might need taken
appart before then is for decarboning or seal replacement, but the
crankshaft and pistons can easily last 600 hours in most cases on the 447.
I don't know many particulars about this engine, but I am thinking of trying
one on a single placed powered parachute that we just became a dealer for.
Probably not this summer, but maybe next spring we'll look at getting one.

Ben,
At 2,000 propeller rpm, the Victor 1+ with a 2.7 to 1 reduction is turning 5,400
rpm. The 447 with a 2.58 to 1 ratio will be turning 5,160. The Victor has
a longer stoke so the 447 beats the Victor with less piston travel per rev to
give the same prop speed.
But if one looks at the equal horsepower being produced by each engine, things
look a little different. The 447 develops 39.6 hp at 6,500 rpm. The Victor develops
the same hp at 5,286 rpm (estimated by linear interpolation of Simonini
data between 5,500 and 5,000 rpm and hp). Victor stroke is 76 mm -> 2.992 inches.
447 stoke is 61 mm -> 2.402 inches. If one calculates single piston travel
per second, the Victor piston will travel 43.9 feet, while the 447 piston
will travel 43.4 feet. The piston travel difference is negligible but radial
bearing loads are much higher for the 447. I believe the Victor will run the
entire 600 hour tbo at 5,286 rpm and I doubt the 447 would make it at 6,500
rpm. Rebuild cost for the Victor is quite modest compared to the 447.

I too spend a lot of time and money on Harbor freight. A while back ,
someone on this web site told of a way to always get the least price on any
Harbor Freight tool. There prices vary widely and I have found different
prices for the same tool in the same catalogue. If that person is still on
the list, We all would hope he would enlighten us again. Thanks.

Ronnie,
I would guess that the gear leg you would need is the same size as the Firefly
leg, 1-1/8" diameter tapering to 7/8" at the bottom. This is the smallest leg
that we offer.
The price would be $50 / each plus UPS.
Since you are not listed in our customer list, I have attached a copy of the Risk
& Release form that we require on a first order. If you choose to order, please
complete the form, sign it and return it to me by e-mail or fax, 606-862-9622.
Thank you Ronnie.

More than 30 yrs ago, when I had a shop working on GA, the Mac truck
would be on me like a wet shirt. Used to buy a few Macs, but mostly
Craftsman because they'd replace all bustid tools--fairly expensive, but
good. Now outa that biz, and have been buying Harbor Freight for quite a
few years. Quality not as good as Sears, but unless you're doing a LOT
of work, HF is a better buy. Just don't put a 4' extender on a a
half-inch socket! By the way, Sears now puts in a rebuild kit in their
ratchet handles instead of giving you a whole nuther handle! Every once
in a while I return a 50+ yr Craftsman tool which was dull cad plated.
They say it's not Sears as all Sears are chrome. I just point to "Craftsman."

You've pointed out linear piston distance in good detail, but I was
mistaken on the more fundamental issue that one must be going twice as
fast as two. (Thanks to Tom too.) Reality is just that the 447 crank
gets a power stroke every 1/2 revolution, compared to once per rev for
the single cylinder 2-stroke.
OK, now that my brain is back :) it is even more impressive that
Simonini is pulling more HP out of less displacement at less rpm.

Hello Rick,
I am curious as to the total installed weight of your power plant?
VW engine and reduction along with any necessary special mounting?
Have any idea of how it compares with the 3cyl Suzuki with turbo?

Bob and gang...
I worked for sears in the tool dept. in the 70's and i have kept some really
old goodies from the teens and twenties that are a gem to look at...in my time
at
sears i have replaced thousands of tools over a ten year time and used to get
them from time to time from a burned building and even though there were burned
to a crisp, you could still read craftsman...i would also joke with the old
timers (i was 17 at the time and they would be about 70 or 80...no kidding back
then they did not have the money so they fixed everything during the depression)
as they would ask, it's lifetime guaranteed right! yep i would say except if you
loose it. they would chuckle!!! Bob and others i will give you some secrets on
the tools...they have been replacing ratchets kits in there for 50 or more years
because it saved the co. money...it was not uncommon for me to replace 10 to 15
ratchet kits per day in those. i had one guy who was a mechanic and i swear he
would go through 4-5 kits a month and eventually the casing will get reamed out
and a new kit is worthless so here is my recommendation to you if you want a new
ratchet and don't want the kit.... just tell them that they have put 3 kits in
it
already and the casing is worn out on the inside...the kid will really think you
know what you are talking about.
thanks,
Gary r. voigt

--> Kolb-List message posted by: <rowedl@highstream.net>
Kolbers,
Was out driving my Mk-3 fuselage around the airport this evening, on the first
pass in which I lifted the tailwheel off the ground I got a hard left turning
tendency when I set the tailwheel back down, after I got her stopped I got out
and found that the right side S hook that ties the tailwheel chain to the tail
wheel had failed, thus causing the left turn.
Will replace both tomorrow with the split link threaded chain links.

Hi gang,
Well Lar is on his way north. He left Klamath Falls this morning after a
fairly exausting three day visit. We managed to attend a fly-in at Grants
Pass Oregon via a 10000 foot trip over Crater Lake. Roger Hankins flew our
right wing. We met Wayne Boyter there as well. When we were taxiing in to
parking I heard some one say that it was the most Kolbs that anyone had seen
in one spot.
The Mark III performed flawlessly with the two of us in spite of the
high density altitude. I sure could use more gas storage though. With 10
gallons and a 582 one needs to plan carefully. I strapped an extra 2.5 gal
to the cage and used my inflight refueling transfer of we would not have
made it.

Great Plains aircraft advertises the reduction drive engine at app. 190 lbs.
This seems fairly close. They have a spec sheet that is online that
indicates 103 HP take off and 80 HP continuance. Again the thing I like is
that this engine runs real nice at 3200 RPM.

Jack,
Hows the vibration compare between the single cylinder Victor and the 447
Rotax, better, worst, the same. Have you flown it for an hour or more at
one time - it shows up more then, like running a weed wacker.

Sears appears to be getting back in the tool business. I got to the point
I wouldn't waste my time going in Sears to buy tools. They appear to be
coming back now offering 6 point sockets again and many other new tools
worth taking home. As for Harbor Freight, I got involved with them just as
they began sourcing their tools from China instead of Taiwan. At that time
the Taiwan were much better, and still are in many cases. Out side of the
air powered rivet puller I didn't have very good experience with the air
and power tools back then. Recently my Dad and I have each purchased their
sliding miter saw, works good for $99 it cost.

Rick:
How did you make out with the CG range. We just gave up with a very sweet
running VW power plant on a Mk III, because the aft CG came out at 27.5"
instead of the rear limit of 24". Our engine came in at 200lbs. This W&B was with
a
light pilot plus full fuel.
Now we are looking for a 582 and start all over again with mounting, cooling,
instrumentation, etc. etc.

I spent some time in Taiwan, and liked to wander around seeing what the
people did. Came on a dirt-floored machine shop(!) where, upon closer
inspection, saw U.S. inch-type open and box ends (ring spanners to our
Canadian friends) being forged. No safety devices, hot metal flying all
over, but tools looked pretty good after the polishers (with no masks or
goggles) finished them. The workers got pennies. Manager said he'd put
any name on tools. Didn't see Craftsman!
