A tutorial video to make a slingshot using 8 mm thick cold-bent steel rod, and a new, simple flat band attachment method. This slingshot will easily handle very strong bands for large ammo.
Note: You will need a rod bender, like the one I purchased here via Amazon (BAC Industries USA):

The width between the large and small rod bender pin on the metal base is 2.5 cm (1 inch), and the width between the large rod bender pin of the metal base and the actual rod pin is 2.5 cm. This makes it possible to achieve fairly tight bends with the help of the dies included. It is possible to bend stainless steel rods up to 8 mm (0.31 inches) diameter with this sturdy rod bender.

01.18 – 04.48 = Cold bending the 8 mm steel rod into shape.
04.59 – 10.37 = Making the wood attachment blocks for the bands.
More technical information is available below:
The cost of the basic materials is approximately US$ 10. Time required to make the slingshot, depending on tools and skills: approximately 3-4 hours. A project well worth the effort for a high quality slingshot that can shoot up to 20 mm steel ball bearings with very strong band sets.
The process shown in the video pertaining to the flat band attachment block system is subject to “patent pending” status.

Accurate bending is essential for this particular project, particularly with regard to the sturdy insertion of the fluted “attachment blocks” inside the fork loops.
The “attachment blocks” are made of beech wood, and contain filed grooves for the reliable wrap & tuck attachment of rubber flat bands. Tight tolerances ensure that these blocks, which have fluted sides, remain inside the fork loops, and no glue or other fixing method is thus required.
There is no danger of these blocks suddenly becoming detached and being flung back at the slingshot shooter during band extension, because the thin strips of rubber used to attach the flat band ends on the forks (wrap & tuck method) are tied externally around the fork loops themselves.
The fact of higher forks (fist grip “over-the-top” slingshot) and the rotational force applied to the wrist when shooting may be a disadvantage to some shooters. However, given that flat bands produce significant levels of velocity and power at relatively low draw weights compensates for that relative drawback – particularly when compared to the higher draw weights of rubber tubes in similar slingshot designs.
Enjoy this video, and let me know what you think about this new design (currently subject to a “patent pending” status) in the comments section below.
