Subject: [SCA-MissileCombat] New APD Approvals for Wooden Shafts...
Society approval


Greetings to the list!

I just received word this morning from the Society Archer Marshal, THL
Gwilym.. that we have Society approval on two new APD's.  He asked me to
post this to the list, so we can try and get the word out quickly and to as
many people as possible.  Please help spread the word and feel free to
forward this email and post it wherever.

These are the two new ones that have been approved for arrows and bolts:

Ruperts Ridged Golf Tube APD (on wooden shafts):

The Reinforced Golf Tube APD(on wooden shafts):

I don't have a website yet, but I plan on taking pictures and enlisting
Evian's assistance in getting it on a website.  I'll send out a notice when
it's up.

Specifications on the Golf Tube APD's:  The minimum length for the top of
the APD is 1 1/4".  Minimum length for the bottom length of the APD is 2
1/4".  The cut of the APD from the bottom (or base) to the top, from the
plane of the arrow, is a maximum angle of 50%, the minimum angle is 30%.
You must use strapping tape to attach the APD's.  You may use an adhesive
along with the APD.  I had good success with high temp hot glue.

The Ridged Golf Tube APD has to be melted.  The ridge should be within 1/16"
or 1/8", it can't be thinner, thicker is acceptable.

The Reinforced Golf Tube APD is cut to the sizes above.. with an additional
piece of golf tube between 1/2 to 1 1/4" (3/4" was my preference) put on the
outside of the golf tube APD.  Since the reinforcing piece will have a gap,
cut the edges straight and put this on the bottom of the APD.  This will
give the shaft a place to rest.
You can use strapping tape to attach the two pieces or melt the back ends
together (which works well).

It is strongly recommended if you use black golf tube that you spray paint
or cover it with light covered tape.  Please pay particular attention to
black golf tube APD's on hot days (over 90%).  Any golf tube APD, when
squeezed that fails to hold it's "o" shape, fails.  I recommend that it
should get cut off at inspection point (to avoid possible problems, with
someone shooting it by mistake).

Other designs and styles of APD's are still being tested and reviewed.  We
are currently reviewing and would like more test results on these
styles/variations:

Golf tube APD's with caulk "Meridies design" (wood & Fiberglass)
Golf tube APD's on fiberglass shafts
Siloflex 75 and 80 psi APD's (wood & fiberglass)
Siloflex 75 and 80 psi, reinforced APD's (wood and fiberglass)

If you have been testing the above designs or a different one, please send
your test results, as soon as possible.

If you have any questions or need clarification, please contact THL Gwilym
(LONGBOW at SGI.NET)or myself. Thank you.

Tessa the Huntress
Deputy to the Society Archer Marshal, THL Gwilym
