After the great response I received on the prop hub question, I thought I would
try again with the prop itself. I'm using a wood Sensenich wood prop. To bolt
the prop to the hub the Jabiru manual calls for AN4-46A bolts with Belleville
washers and nylock nuts. The Sensenich installation manual calls for safety
wiring the bolts.
So, here are my questions.
I don't seem to find Belleville washers at the online aircraft supply stores.
Are they called something else?
Should I get bolts with pre-drilled heads and safety wire them?
I would think there is no point to drilling and wiring the nuts, as they could
not be re-torqued without replacing everything.
Is there anything else I should keep in mind?
Thanks in advance.

I just checked whether AN5 bolts would fit, and while they will go through the
propeller (looks like the propeller could even take AN6) the mounting bushings
and plate are drilled for AN4.

Yes John: I worked on my Lightning from the 7 th to the 18 th and put the
prop on either the 17 th or the 16 th. I had to drill out the mounting bushings
and the front plate to take the larger bolts. I do not remember what size I
drilled it out to. I recommend checking with Nick or Mark at Arion. (Yeah I
know, they are at Oshkosh.)

All,
I have read the kitplanes article from the September 2008 issue. I haven't seen it on the shelves yet, but you can buy it pay per view here: http://www.kitplanes.com/issues/25_9/flight_reports/issues_flightreports_8344-1.phtml or if you're a geek like me you can get it now and then get the magazine when it comes out too! It is a great read that will show you some of the development of the safety, reliability, and feel.
The last one, although I have not gotten a chance to fly the latest verion of the
Lightning is a big one. I loved the only slightly positive pitch stability
of the original. I know that Buz and Nick felt the same way. This made it feel
a lot more like an aerobatic sportplane or a fighter. The change in feel
does make the plane much easier to fly, more forgiving, and eases the pilot workload.
The new engine mount moves the CG forward, improves feel and safety,
and in my opinion makes the plane look even better.
You'll notice that the guy who wrote the article had to get through to the current
demonstrator in improvements before he liked the handling. Everything else
he loved about the plane except pitch feel. I won't spoil the ending by telling
you what he thought about the new changes, but I will say this: the guy
was lucky enough to fly 3 Lightnings! I think he was just trying to get a little
extra free stick time personally ;-) Brian W.

I have mixed emotions about the article. I tend to not enjoy articles as
much when the author has multiple opinions throughout. I also think he
should have done his review based on the current production model. If you
know you are going to write about the latest version, why comment in detail
about the older one?
I'll leave that where it lies and then add some additional thoughts later.
I don't want to ruin it for anyone either...
Jim!

There was a discussion of this some time ago on the Jabiru engine list. See http://forums.matronics.com/viewtopic.php?p=37783
This talks about a source for washers here
http://www.mcmaster.com/
but I'm sure Arion, being Jab agents, could also supply.
The Jabiru assembly manual also has some words on the differences between Jabiru
and Sensenich prop mounting in their constructors manual here
http://www.jabiru.net.au/Manuals/Airframe%20Construction/Sections/Post-Paint_Fuselage_Engine_Fit%20propeller%20and%20spinner_JALL.pdf
As I understand it, the differences in securing methods between the two prop types
are largely driven by the Sensenich being built from harder timber than the
Jabiru.
It seems from the above that there are several methods which can be used to secure
the mount. If methods which secure the nut to the bolt, such as locknuts
or castlenuts, are not used then it is important that both ends of the fastener
are secured. That does mean that lockwire for example will have to be removed
each time the tension is to be checked.
Those of course are just my thoughts. The real wisdom on securing is in "the bible"
AC43-13-2B. Some good stuff on fasteners, nuts, lockwiring etc. in Ch 7
Cheers.
