Subject: [SCA-MissileCombat] Bulbous nocks, ABDs and others


>I would like to have some testing done with the UHMW bulbous nocks, the
>various ABDs and any other designs that are veing worked on. I think we
>may be abvle to come up with a variety of devices which can reduce or
>eliminate injury from the nock end of an arrow.

>I will be writing up  instructions on constructiing the UHMW bulbous nock
>in  about a week. So anyone that would like to make and test some of them
>please let me know. Those of you that have been working on other designs,
would
>please you post information on their construction, so that others could
make
>and test them as well. I may have a few extra bulbous nocks I can mail out
>for testing as well.

>A possible varient on self nocks on wood arrows would be to add a 1/2 or
3/4
>inch length of 5/16 vinyl tubeing over the nock end of the shaft, glue it
to
>the shaft and then cut the nock slot through both the wood shaft and the
>vinyl tubing. Then cut/round off the edge of the tubeing. This would
>increase the contact surface and soften the edge of the wood shaft. Most
>vinyl tubeing is about 1/8 of an inch thick, so it would increase by
>about an 1/8th of an inch on the side that passes the bow. With a
>11/32nds shaft this would make a 19/32nds thick nock.

>Possible varient on the above....Adding the vinyl tubeing over existing
>hard plastic target nocks????
>
>The SEM wants us to decide what would be workable as replacements for the
>hard plastic target style nocks. So we need to make some and then test
>them over a period of time, so that we can have some findings to present
>by Pennsic.
>
>Let me know what designs there will be to test. We can then work on some
>testing standards for them.

>Someone was going to contact Duke Baldar and ask him about the posibility
>of him making some form of abd or bulbous nock. Was there any result from
>this?
>
>Your comments please.
