Offered for your consideration, comments, suggestions, and advice.  I continue to have difficulty launching a standard 30" arrow from a slingbow using an archery nock to interface w/ the slingbow.  

 

The arrow is based on the Filipino pana.  12" long and fletched w/ 3, 3" turkey feathers, 100 gn. field point.  The nock is a bent paperclip to attached to the string on the slingbow.  I attached the nock to the front of the arrow, near the point, w/ whipped dental floss.  The arrow is gripped on the back end, near the fletching.  The grip needs work!

 

Slingbow is a modified Trumark WS-1.  4 office rubberbands, gypsy tabs.  The string is a piece of cotton butcher's twine.

 

This design is showing promise.  I am able to launch the arrow fairly accurately at this point.  I am not able to get as good a draw and as clean a release with the current grip design.  

 

Looking for advice regarding grip design.

 

The floor is open for questions and comments.

Also on your set up if you use weed eater line you won't have a return to sender as bad the string will catch and not let go

Ghost - great set-up.  Thanks for posting?

 

Are those carbon shafts?  How do you cut them?

 

It looks like you have several different grain weights for your field tips - does it make a difference in arrow flight?

 

How you you keep the wing nuts from sliding up the shaft?

 

Did you make the slingshot?

Yes carbon arrow I cut them with a Dremel cut off wheel.yeah a few different weights don't really affect the shooting because the arrow don't flex the nylon wing nut is held on by friction is all

I did not make the slingshot it's called a shuttle craft by wingshooter it has a rotating head it will always line up when shooting.

Hi Blue Raja,

Thanks for your interest. 

 

When I draw, the arrow shaft raises up off the arrow rest.  I cannot generate sufficient force from the bands to get good arrow flight.
