Hi All,
Calling all Europaphiles down under - thats Australia (or is the UK down

We are visiting our daughter near Brisbane at the end of August this year

in the area and share a beer.

I had the struts made to Kingsley Hurst's drawings and fitted them to work
well; but it is challenge to get them correctly set in place.

I did not miss the Europa; I had fungi in my lungs and an aging head. I have
returned to attacking the fungi and I bought a book about stimulating the
mind while I was at Kennedy Space Centre; so things are looking good.

Subject: | propeller shaft alignment w/ cowl |
Gentlemen,
As per previous posts, I'm installing a MPEFIed Sube derivative engine
and have made my cowls from Alex Bowman's molds. I'm presently
confronting an issue common to the stock engine installation and am
looking for some counsel.
I've adhered to the build manual w/ regard to P factor offset, and my
prop shaft at the flange is spot on the fuselage centerline; however,
it is about 1/4" high. I'm confident that I can lower it by adjusting
the thin washer count at the intersection of engine mounting frame
with the europa mounting frame.
With the fuselage secure in its cradle and my smart level reading zero
deg. at the port door sill, my reading of the vertical face of the
prop flange is 89.9 to 90.0 deg., depending on the weather, or time of
day (who knows?).
I've noted the caution in the manual to ensure that the plane of the
prop flange is 90 deg. to the waterline. And I'm aware that raising
the prop flange to center it within the cowl prop opening will affect
its verticality...perhaps by as much as 0.2 degrees.
As a matter of superficial aesthetics, I'd like to center everything
up...at the same time, I'm leery of conceding that the plane of the
prop flange will be "off" by this amount...so my questions are:
- Would 0.2 degrees off from true vertical of the plane of the prop
flange be within acceptable limits?, and,
- Would anyone comment on their experiences in addressing this issue?
One of my mantras has been, "I can only strive to achieve
perfection"...that's fine enough overall, but I'm sure there are
individual aspects of our build where perfection is both achievable
and mandatory.

Subject: | Re: propeller shaft alignment w/ cowl |
Fred,
When doing the landing gear frame mods, I had trouble getting the
spinner to align with the cowl on two aircraft and I fudged the
elevations of the engine a bit to make it look pretty (well better). No
difference in anything I could feel flying. I think the farthest off
was my own at about 1 degree off vertical, but when laying the level
across the head bolt studs it was within .2 or .3. I think my digital
level is not as accurate in the vertical mode.
For what it's worth. We measure with a micrometer, mark with a grease
pencil and cut it with a hack saw and grind to fit. There will be
variances.

Bud...reminds me of a builder's preferred remodeling spec from an
