Designs that failed or were dropped from Testing

Lasted updated 9/23/04

APDs

 Below are the APD designs that failed during testing.  These designs are not legal.  Please read carefully since some failed on wooden shafts, but passed on fiberglass

1.Bottle Cap APD failed before 07/01

This version was made using a 2 liter (or 16 oz) soda bottle cap. A hole was punched into the cap and it was attached to the shaft, using the hole to go over the nock/shaft. They wouldn't stay on the shaft and there was a problem with breakage.

2.160 psi Siloflex APD on wood failed before 07/01

 This is the same as the passed versions of the 160 psi APDs. During testing it was found that using this APD made the majority of the shafts break on impact. So this version was not approved for use on wooden shafts.

3. Flexible Disk APD (version A) made from 1 5/8" disk failed 12/28/01

 The two major differences between the failed and passed versions is the thickness and the stiffness. I can't show the stiffness here, but if you have a sample of the passed version, you can tell the difference. Picture 1  Picture 2

4. 1 1/2" and larger Funnel APD's failed 01/19

5. The Flexible Funnel APD (made from ear syringe bulb) failed 9/05/02

 This was made from a very specific ear syringe bulb. The two pictures below, show the failed version (the blue one in the pictures) and the one that's currently  being reviewed/tested for Society approval. You can see the difference in size/diameter. There's also a difference on where it's mounted on the shaft. The green version made from a stiffer material. The failed blue version had a Blue foam plug that could and did come out without warning.   Picture 1   Picture 2

6. 100 psi Siloflex APD without a routed channel or tab, using Goop adhesive and a different taping method .These can fail with no warning.

 7. Adams mfr. Suction cup. This was submitted as a possible alternate material for the flexible disk APD. This material has been failed. It did not pass the hand pressure test.

Shaft Material

Below is an index of shaft material/types that failed during testing.

1.        160 psi Arrows and crossbow bolts. These failed during testing. They hit excessively and they caused at least one injury due to excessive impact.

2.      Icicle,Safety sleeving used as an alternate shaft material (instead of Golf Tubes or Siloflex tubes. Page of photos.  It was tested in An Tir.  This has been dropped from the testing.  The tester decided to put it on hold for now, to give time to check for UV effects.  There is concern that these will break down or weaken when exposed to sunlight.  There is a major concern that you can not tell the difference between the high quality and much lower quality varities of this sleeving.  The PVC in the head needs to be replaced with another material and the head needs to be built up to prevent over-drawing.

Blunts

3.      Modified (using tools) Egg-shaped Baldar Blunts Modification "A": This one has 1/4" of material removed from the front of the blunt, leaving 7/8" face surface with ½ " of material in front of the nylon insert. (blue tape) Was tested in An Tir, Atlantia, East, Meridies, Trimaris, and the West. This one was still penetrating more than 1/2" into a helm. This failed the testing.

  3.  Modified (using tools) Egg-shaped Baldar Blunts Modification "C": This one has 1/2" of material removed from the front of the blunt, leaving 1&3/16" of face surface with ¼ " of material in front of the nylon insert (green tape) Was tested in An Tir, Atlantia, East, Meridies, Trimaris, and the West. This one had too much material removed and the shaft would punch thru the rigid disk and through the blunt. This failed the testing.

          4.  Using PEX with Baldar blunts on fiberglass shafts. This makes a Baldar blunt designed for wooden shafts fit more snug on a fiberglass shaft. The PEX passed the testing, the wooden baldar rigid disk, failed multiple times during testing. The Baldars made for wooden shafts are not approved for use with fiberglass shafts.

  5.  Modified Egg-shaped Baldar blunt, version 2 (manufactured by his Grace Baldar). Was tested in Meridies, Trimaris, Atlantia, and An Tir  This one failed the testing.

 6.  Modified (using tools) Egg-shaped Baldar Blunts Modification "B": This one has 3/8" of material removed from the front of the blunt, leaving 1&1/16" face surface with 3/8" of material in front of the nylon insert. (yellow tape) was tested in An Tir, Atlantia, East, Meridies, Trimaris, and the West. This one failed the testing.

7. Heavy UHMW blunts with 50# bows.  There were several problems during the testing of this combination, including a lack of test reports, progress reports etc.  Since these arrows look so similar (almost identical in some cases) to the lighter UHMW arrows, there is serious concern that someone will use the wrong arrow from the wrong bow.  Since a lot of archers do not know what’s used in other kingdoms and it’s common to borrow bows and/or arrows at interkingdom events, this is a very real possibility.  Since our “light” arrows are not safe being used on 50# bows, this is a very serious concern. 

There were multiple reasons for dropping this combination from the testing.  Another major point is that this combination can not be used at the same time as lighter missiles, so this would make more major differences in the combat archery rules and will be a major point of difference at interkingdom events. 

 If you have any questions, please send me an email.
