Figure 8 Descender Sling Bow
May 11th, 2017 at 2:58pm
 
I'm still waiting on the serving thread for my ski bow's bowstring, so with that project still unfinished (along with some other projects I really should get on with at some point...) I thought I should start a new one! Cheesy

I came across this instructable: http://www.instructables.com/id/The-BEAST-Barts-Eight-Arrow-ShooTer/

and instantly fell in love with the simplicity of it and how portable it is, being very thin and not that large and bulky. Now the original instructable has a lot of problems I've noticed already; the rubber bands used are really very weak, the attachment method isn't the best and it would really benefit from a whisker biscuit or some type of arrow rest.

I have my 8 ring in the post (this one: http://www.ebay.co.uk/itm/35KN-Rescue-Figure-8-Descender-O-ring-Hook-RappelDevic... )

and I have solutions for the first two problems, but I was wondering with that last problem, the lack of a whisker biscuit, what sort of solutions do you guys think would be best?

Currently I've thought up three options:
1. Attach an actual whisker biscuit which is the most expensive option and it's liable to damage from the bands following through so would need protection or frequent replacement.
2. Use toothbrush heads which I've seen used quite often with DIY slingbows and would be pretty cheap.
3. Attach a piece of flexible plastic such as from a bottle to hold the arrow. This would be the simplest and the cheapest so is certainly appealing though would probably need some testing to see how well it works.

All comments and suggestions appreciated Smiley

Oh I found another method! The Slingshot Forum should have been my first port of call really. A piece of stiff leather! Ingenious and I already have some perfect leather for the job!

You may already know about this but its sort of similar. Slingbows are cool though. Great compact hunting weapon.

Oh yes I have seen them but I've always been a bit too intimidated to actually try one out. I don't even have my ears pierced and I don't fancy getting a hand piercing Cheesy

so it just a catapult bow without a whisker biscuit.

Seen a few how tos on making your own whisker biscuits.  You really don't want any part of the arrow bouncing off the side.

Yep. Yeah I think I know how in going to do our now but I'm going to test it out a lot to really make sure it's all secure and not bouncing around inside the ring.

Iíve given it double Thera Band Gold rubber with an archery string with serving. For the release, Iím using a bead. Iím not sure if is the best idea, getting hit by the bead would suck so Iím hoping my other modification will help with that. I went through lots of ideas for the arrow rest but Iíve now decided on a rubber band tied down with serving string (I really need to make a sling from this stuff, it's great). Iím hoping itís going to have enough friction to hold the arrow in place but be flexible enough to allow the arrow to pass by. Hopefully it will also stop the bands from passing through the ring with too much speed and stop the bead breaking my fingers Cheesy String stops are used on full bows so maybe this will have that effect as well.

I'm not sure if I've posted this before but I thought I'd add it here. I made a slingshot using a bolt, a wing nut and some string and grip tape. Double thera band gold means it's pretty darn powerful and because it has such low forks it works pretty well as a sling bow! Wooden barbecue skewers are the perfect size.
