What Richard is talking about is often called running torque and he is
correct in adding it to the original torque figure. AC43.13 page 7-7
para 7-40 (d) "Add the friction drag torque to the desired torque....".
My 2 cents

The torque on the wood prop was to give the correct amount of crush on
the
wood
at that torque not to have that added to it.Consult the correct torque
tables, they will
give it to you and don't just add to things because one thinks that is
right as that
could over torque the bolt. There are specific torque's for certain
grade
of bolt
or for certain parts never exceed those values.

OK, so you got your wrench calibrated within a gnats eyelash. Are you
actually measuring the torque correctly?
First, measure the drag the nut / bolt combination exerts. Those nuts
with
the inserts will give you a few inch pounds. And the wood on my wood
prop
initially gave several pounds.
Then add the drag to the specified torque and use that number for your
torque setting.

I have one of the earlier 2002 engine packages which I would like to sell. I
bought it for an rv9 but I know it will fit some other rvs.
engine package
heater package
EIS monitor no fuel sensors
fuel valve
Oeitiker kit
1 metal tank and 2 gallons of antifreeze
engine manual
Will sell for $15,500.00 about what I have invested with no markup
email me if interested at _carlrayw@aol.com_ (mailto:carlrayw@aol.com)
It has been stored in a heated garage and is still in the crate. I have used
a wrench to turn it over occasionally so I know it is still ok. Was going to
start it up but decided it would be better not to unless I don't sell it,
then I will have to run it occasionally till I sell it.
Reason for selling is that I don't think I will get to finish and fly my kit
for a lot more years if ever so rather than have it sit for much longer I
would like to see someone get use of it. A hard decision to make but something
I
must do. I would like to have someone pick it up or I could deliver it for a
shipping charge. I live in Michigan at Traverse City.

This was friction drag on the bolt from the wood, The holes were so tight
you had to tap the bolts in and there was no way you could turn them by
hand. Measured as high as 3 ft. lbs. The spec called for 17 ft. lbs (I
don't remember the inch lb. numbers), so without adding the friction drag
amount I would only have gotten 14 ft. lbs, short of the spec by 17%.
