Here’s my most recent shop project. It’s a magnetic switch table saw fence. My table saw’s old fence was never consistent, and I hated the front to back clamp system. I’d love a Biesemeyer fence and the front alignment, but they’re definitely too pricey/fancy for my used Craftsman contractor saw. I was bent on building a custom fence that locked onto a front rail. When thinking of what to use as the front rail, I realized the milled front edge of a table saw top is as accurate as any rail I can attach to it. That’s how I ended up with the magnetic table saw fence idea. I don’t think I’ve seen anything like it on the site or anywhere else.
The fence is designed with two switchable magnets that secure it to the front edge of the table saw. The two magnets allow this fence to always stay in alignment no matter where the fence is along the front edge of the table. The fence can be tweaked by loosening and re-tightening a couple bolts. I picked up the switchable magnets from Harbor Freight Tools for about 12 bucks a piece. (I would have used Magswitch magnets but remember, this thing wasn’t suppose to be fancy.) The faces of the fence are cut from leftover maple engineered wood flooring. I also custom cut a pistol grip handle to aid with alignment.
The fence works well. The fence has minimal flex when pressure is applied. The magnets are rated at 45 lbs a piece which adds up to 90 lbs of force holding this fence to the table! I was pretty satisfied with the results, and it sure beats shelling out $400 bucks for a new fence. Enjoy.
