Anti-Kickback System for Tablesaws

A gave myself a nice birthday gift the other day. Filed patent with the USPTO on anti-kickback system for tablesaws, so I can disclose it. A project important to me as I have experienced kickback a few times and made it a mission to fully understand it. Addresses table saw safety and the pervasive problem of dangerous and violent table saw kickback. The AKS system actively mitigates kickback. It can electronically sense 3 common kickback conditions and activate a braking system. The project began 3 years ago but I abandoned it due to its complexity. There were insurmountable technical hurdles that involved considerable more research.

This summer I once again embraced the project and pushed through the technical hurdles. The table saw in the video is a purpose-built prototype for testing of and demonstrating the AKS system. There was a huge learning curve to be able to accomplish this, develop the software to control it all, understand motor control and fabricate the prototype. AKS system can be integrated into any new table saw on the market. Best part is it works and exceeds expectations!!

Table Saw build...

Someone might ask, why would you build your own table saw?  I agree, there are so many inexpensive ones to choose from out there. Why re-invent the wheel?  Well, there is some logic to my madness. This table saw is a work in progress and will have features not available in current table saws. So without going into any more detail, here is a glimpse of what I have so far. It is a scaled-down version of a bench saw, has an adjustable fence and sports a 7 in. thin-kerf blade. I'm actually enjoying this build and the research necessary to make my idea work. I won't be discussing the drive motor and any of the features until a later date.

There is more work to be done but at the moment it does function as a mini table saw.
