FingerTech's Blade Hub is the best way to attach a blade to a shaft. It uses a flange nut to hold the blade tightly, meaning you can use off-the-shelf sawblades without needing to drill screw holes into hardened steel! Custom blades can be made stronger by not having those same mounting screw holes.
• The stepped design allows use of blades with different bore sizes (10mm, 16mm (5/8in), and 20mm).
• A clamp mount with two screws attaches the hub to your weapon motor shaft. (Remember to apply thread-lock.) (This replaces the 8-32 setscrew in the previous version.)
• The hub has a 6-32 threaded hole so that your horizontal spinner robot can rest on a screw head and not be pulled in different directions when the blade spins. Also useful for supporting the hub's far side in vertical spinners.
• Add a vicious horizontal spinner weapon to your Viper Combat Robot!
• High-speed brushless motor and controller plus a FingerTech Blade Hub.
• Mounts on the existing Viper Combat Robot. (Requires modifying the original plastic armor, or buy a new set here: Horizontal Spinner Armor Set)
• No soldering required!
(Blade not included. Shown with Titanium 6-inch Weapon Blade)
