I am not a big fan of slingbows. They will never shoot as hard as true bows EXCEPT you make them equally large. If you go compound (full blown cams / let off mechanism), then they even look like a bow and cost just as much. The hand held slingbow can maybe rival a weak recurve, but is has to be shot with a release due to the steep angle of the string. However slingbows are very compact and they are fun to shoot. They are also very popular among those who also like archery. The commercial models that are on the market are fairly horrible, but expensive. I am thinking about designing a model and offering it in the store. Plastic molding of course. Target price is the same as the Rambone. Currently my idea is to use a replacement whisker biscuit as an arrow guide. You can get Chinese ones for under 8 bucks end user price. http://www.redneckpoint.de/Pfeilauflagen-Bogenjagd-Jagd-Booster-Whisker-Biscuit-schwarzBooster-2 I want to use a Rambone handle, but redesign the fork so that you can mount all of the available whisker biscuit replacements (also the original ones) into it. The frame will protect the biscuit from the onslaught of the bands, a problem that is often ignored by home made models. The biscuit needs to be recessed into the frame, otherwise it will loose its hairs more quickly than your run of the mill werewolf when the sun comes up. Of course this won't be the most powerful slingbow in the world (I made models that are better), but it has to be affordable and compact to be a commercial success. What do you think?
