Compared to most of the rest of the week, this was a pretty relaxed morning.
Wednesday was (according to the orignal plans) a day on which we were going to be
joined by Mike, but because we wound up being ahead of schedule, Jacob and Mike
decided that it would be best if he came in on Thursday and Friday instead.
In any case
we sanded a few parts that still had rough edges and then Jacob went to the paint
shop with all the parts. While he was in there, we wandered over to Don's
Dream Machines, an engine shop (although they do other things, too) that has been
doing some interesting things with RV-sized engines.
After talking to the engine people for awhile, we came back to Alexander and started
peeling blue plastic off of the skins that had been primed. We didn't get too far with
that before it was time for lunch.

No, folks - the sign isn't there because he has gas.

Jacob's mixing the primer. Fortunately, this photograph doesn't convey
the smell.

Off to the engine shop - here's the front door of Don's.
|
RV-8 that Harry Hughes (customer of Don's) is building.
|
This is an O-360, not the angle valve IO-360, but they've still pushed it to
200 HP. Interesting . . .

Apparently they way these guys are able to get 195-205 HP out of what's normally a 180 HP
O-360 is by using the exhaust system that's pictured below, and making
it a high compression engine. This seems like a way to get 200 HP if you don't want to
haul around the heavier angle valve IO-360, but I don't know enough about engines to
know if this is a good idea or not. Anyone out there have any advice?
I've also heard that Hartzell recommends that you not use their propellers with high
compression engines, which makes me a bit cautious - as it would be a bit silly to put a
fixed pitch prop on a 200 HP airplane, this means I've got to spend a pretty serious amount
of money to get a composite prop - Whirl Wind or MT, I suppose. I'm not really
anxious to do that.
On the other hand, I think that Don's would build
an engine without the high compression cylinders - if I want to use a Hartzell prop, maybe
that's the way to go.

Exhaust on Harry's airplane - this is Don's replacement for the Vetterman exhaust
system - it's a bit heavier and more expensive, but it's supposed to last longer and
adds 6 HP.

RV-6, also in Don's shop, that is being built for a customer.
|
First panel for the RV-6, planned for a Blue Mountain EFIS. Customer changed his mind . . .
|
. . . and this is what they're going with now.
|
Don's MA-5 Charger. Don and Jeff (his son) are planning on redoing the
fabric sometime this spring.
|
Note the GPS antenna - not the sort of airplane in which
you would expect to find a Garmin 430
. . . but you'd be wrong.
|
The MA-5 is powered by one of Don's engines. I like the machine finish on the
firewall.
|
Skins back from the paint booth. Note the nice green primer.
|
Peeling off the area of plastic along the rivet lines.
|
I'm not sure if this is worth it, as it is a pain in the rear. Probably it's
lots easier
to yank all the plastic off now.
|
The Alexander folks let us sit in a Cirrus that was being repaired there . . . these
are nice airplanes if you don't mind flying something factory-built, I suppose.
|
Well, it's off to the kitchen to grab a few sandwiches and head back to the shop
to keep working on removing the plastic.
