The guide bushing of the plunge router machines

The next video is in the works. Meanwhile, I’ll take the opportunity to share some photos of the router guide bushing. A few days ago, someone emailed me asking what it was and how to get one. The guide bushing is a plate that screws or fits into the base of the router. It has a hole surrounded by a ring that protrudes from the base of the router. The purpose of this ring is to rest against whatever we use as a guide to ensure our bit follows the desired path (something almost impossible freehand without any guide). Each brand of router has its own model, so make sure it comes with the router you buy.

If you have a router (an increasingly common power tool in our home woodworking and DIY workshops) and didn’t know what a guide bushing was and can’t find it, you might have stored it somewhere in your workshop. If you can’t find it, perhaps the technical service can get you one. Another option is to buy a universal router base, which usually comes with bushings of various diameters.

What I don’t know is how a universal base would be installed, whether it would be screwed directly to the base of our router or if the base would need to be removed and the universal base screwed to the guides.

When using the guide bushing, make sure the bit doesn’t touch the ring (easy if the ring hole and the bit diameter are almost the same), or you risk damaging the ring (and maybe the bit, but a new bit is easier to get).
