MagJig 150 Switchable Magnet
Avoid the hassles of creative clamping while trying to secure jigs on a work table. MagJig gives you flexibility to mount anywhere on a steel surface, such as your table saw, jointer, shaper,...
- 150 lbs. of holding force each; two or more MagJigs per fixture is ideal
- Rotate knob to engage the Magswitch; when you’re finished, turn the knob to disengage
- Fits perfectly in a 3/4"-thick material so the bottom of the magnet is flush to the table surface
- Screw holes provided to securely mount MagJig to your jig or fixture
- 40mm hole required for installation
Alll I Can say is that its fantastic
As a fence for my bandsaw,its very easy to use.I made a fence using a formica sink cutout and mdf, tuned my bandsaw and can now cut very thin slices that are ready ti use
Make adjusting a fence simple.
Great for aligment fixture on the table saw, drill press, and the band saw. Turn it on (locks it place) / Turn it off (moves with ease). Great product.
A fine tool for building tools
Aside from the price, there's not a downside for me. These hold a jig extremely firmly in position as noted in other reviews here. To be sure, you do need a precision fit to the hole you make in your jig, and the local thickness of the jig baseplate should match the hold-down height of the Magswitch. E.g. if making the jig out of half-inch plywood you'd build up the thickness with a quarter-inch piece. I didn't find it necessary to acquire a 40mm Forstner bit -- a little rasping did the job for me and also got a more complete engagement with the actual non-circular shape of the Magswitch (it has flat sides on the 40mm diameter circle). With properly cut holes it's a snap to move between jigs, too.
I bought 4 of the magswitches for use in the shop with various jigs. I already owned the universal featherboard along with the pro featherboard with additional vertical hold-down. These didn't disappoint me - they have amazing holding power. I bought them to use with the ShopNotes issue #103, 5-in-1 table saw accessory, to hold the jig onto the Biesemeyer fence instead of drilling and tapping into the top of the fence. They are more than adequate. I had reservations because the fence, although thick steel, might not be thick enough for the magswitches to get a strong hold. However, my fears were alleviated once I stuck them on the fence - they hold extremely strong. I now have to rig an out-feed hold down on the fence to keep it from lifting. They are fantastic. I'm only wondering how long they keep their magnetism. I've heard they do lose it somewhat over time - something like 10% over a number of years. As such, I will have to wait and find out. Regardless, these magswitches have been great for attaching various jigs to my table saw - they're quick and easy. They absolutely make my woodworking safer because they are so easy to use and so rock-solid in their performance. They are an absolute "must buy" for woodworkers for their ease of use and if you value your safety.
I would buy this again and recommend it.
Used this to fabricate a blade guard that can be easily attached to saw table top. I saw this on Charles Neil woodworking site. It works!
Tremendously Useful (if expensive)
This little magnets are great for making custom jigs to clamp down to the cast iron tabletops on table saws, band saws, drill presses, etc. They are magnificently strong magnets (make sure not to set them next to your cell phone or television) and won't easily move once turned on. The really great thing is that you don't need to permanently attach them to your jig- a precise hole is enough. This allows you to create bunches of jigs and just move the magnets from one to another. However, they require that you drill a 40mm hole through 3/4" material, so make sure to pick up a 40mm Forstner bit when you purchase them, otherwise (if your experience is like mine) you'll be running all over town trying to find a store that stocks the uncommon bit size.
