Jeff Snell has all-but-solved the problem of how to keep your saw blade perfectly aligned when hand-cutting joints. He invented the AngleMag, which uses four neodymium magnets housed in a super-low-friction glide to hold any backless saw, such as a Japanese pull saw, at an exact cutting angle.

The solid cast aluminum body of the AngleMag clamps to workpieces up to 2″ thick with three clamping screws. The pivoting guide rotates to any angle from 45° to 90°. The guide rides on a shaft with grooves spaced every 90°, so you can lock the guide for angles either in the horizontal or vertical plane.  After cutting the first angle, you can rotate the glide shaft exactly 180° to cut the opposing angle — very useful for cutting dovetail joints.

Although the AngleMag retails for $140, you can get it for about $100 from either of the online retailers below.

    the angles are fixed but this one is also interesting for less money:

  2. Simon, I can’t believe I’ve missed that one. I’ve combed through the Lee Valley catalog for hours and have never run across it — one of the great advantages of writing for Toolmonger is that you can spend hours online looking at tools and tell the wife that you’re “working.”

    Besides price, I like the fact that it’s a simpler tool — there’s less that can go wrong setting up the angle and cutting it if you’re just doing dovetails. It also seems like it would be a lot sturdier. It would be interesting to test the AngleMag to see just how sturdy that pivoting guide was.

    If you already have the right saw though, it’d be hard not to spend a little extra on the more versatile tool.

  3. There’s also this one at Japan Woodworker:

    Even cheaper, and variable (in 1 dimension) angle.

    I’m curious to know why that guy is cutting dovetails in the middle of that 1×4, on the edge, no less. If it’s just to demo the jig, wouldn’t it be more instructive (or persuasive) to use the jig like someone might actually use it?
