Make A Magnetic
Table Saw Stop Block


I came across this magnetic table saw stop block made by Ted Raife, editor of Woodsmith Tips and thought it was such a good idea that I wanted to make one just to try it out.

Okay, it's not an earth shattering, life changing invention that's going to change the way you do things — but it's this kind of innovative thinking that speeds up many operations in the workshop.

Measure and cut the stop block These lines are to locate the magnet's center. Depending on the size of your magnets, you may want to locate them farther in or out in relation to the edges.

I pretty much followed Ted's design, although I had to mount my magnets on the bottom of the stop block because my rip fence is aluminium and my table top is cast iron.

I used a piece of 1 x 4 oak which was cut to a 3 1/2" square. By the way, it's easier to miter the 45 degree corner off before the board is cut to size. I, uh, did it the hard way. Duh.

It just so happened that I had a few left over neodymium rare earth magnets from a previous project that looked like they were made for this job.

Bore 3/4

The magnets I'm using are 3/4" in diameter by 1/8" thick. That doesn't sound like much, but these rare earth magnets are very strong.

Because of their strength, I only used two of them, although I had room on the stop block for three.

I bored the recesses for the magnets deep enough so that the magnets were slightly below the surface of the wood.

A forstner bit works great for this as it leaves a flat bottom hole. I actually used a 3/4 " end mill set up in my mill because for some strange reason, I don't own a 3/4" forstner bit.

Glue the magnets in the stop block with superglue

To keep the magnets in the wood, I used a liberal amount of super glue.

The glue dispenser in the picture on the left works by pushing in the orange sides. It's over two years old and has never plugged up.

I remember when they first come out with super glue. It was almost always a messy affair.

You usually got a couple of fingers stuck together and the next time you tried to use it, it was either completely dried up or you had to cut the container open to salvage what little that wasn't. This is much nicer.

Place board against stop block and cut Even though the magnets are quite strong, the block can still be moved inadvertently if hit hard enough. Butt the fence up against the jig after you set your measurement.

That's it. One of many easy woodworking projects that will leave you with a very useful jig that can be set up without clamps, bolts or anything else.

Oh yeah, you can store this stop block in any handy spot on the table saw by simply sticking it to the metal surface.

Still got a couple of these magnets left. Maybe I can find another similar use for them. Hmmm.
