Dear Listers,
The List of Contributors (LOC) is just around the corner! On December 1st I post
a list of everyone that so generously made a Contribution to support the Lists.
Its my way of publicly thanking everyone that took a minute to show their
appreciation for the Lists.
As a number of people have pointed out in their Contribution comments, the List
seems at least as valuable of a building/flying/recreating tool as a typical
your magazine subscription! And how interactive is a magazine, after all? :-)
Won't you take minute and assure that your name is on the upcoming LOC? Tell others
that you appreciate the Lists. Making a Contribution to support the Lists
is fast and easy using your Visa, MasterCard, or Paypal account:
http://www.matronics.com/contribution
Or, by droping a personal check in the mail to:
Matronics / Matt Dralle
PO Box 347
Livermore CA 94551-0347
USA
(Please include your email address on the check!)
I would like to thank everyone that has so generously made a Contribution thus
far during this year's List Fund Raiser! Remember that its YOUR support that
keeps these Lists running and improving! Don't forget to include a little comment
about how the Lists have helped you!
Thank you!

| Subject: | Checking bolt torque |
Hi all,
There has been considerable discussion on the Jabiru Yahoo list as to
how to check torque on critical flywheel bolts.
The owner/mechanic is suppose to regularly check those bolts tension,
but they are bonded with Loctite 620.
How would you experts proceed ?
- Just apply torque wrench and check for movement ? (But remember there
is Loctite)
- Unscrew, extract, clean Loctite, reapply Loctite, reinsert and torque
to specified value ?
- Put red paint on bolt heads and flywheel and just check if nothing
moved ? (but what if the preload relaxed, the bolts stretched, the joint
fretted ?)
- Etc..
I posted some info on bolt torquing and the Jabiru SB which started it all :

Any qualified input appreciated
