Guide bushings are simple devices that when used properly, extend the capabilities of your router. Control and pickup cavities, neck pockets and tremolo recesses are all operations that require the use of this versatile tool, and all of these examples are made much easier and safer by the use of a template and an inverted pattern bit to guide the router around the intended cut. To use it, you temporarily secure the sheet-to-be-cut to the template and then run it through your router such that the router bit bearing rolls along the edge of the template. Template routing comes in handy for all kinds of applications, such as lettering, inlays, and shaping identical furniture parts.
The most critical dimension to know when using a guide bushing is the offset: the distance from the outside of the collar to the cutting edge of the bit. To use a plugin just call the plugin method of Router and pass the name of the plugin and any options for the plugin. Also, in order to prevent the bit from grabbing the workpiece at the start of the cut, I extend the template beyond the workpiece. We could create a helper on the Post template called title or we can set a data context for the template directly from our route function. If you’re using a bearing-guided bit, position the bit so that the bearing makes full contact with the template.
Sharpening straight router bits costs less than the up spiral bits and I can easily hone the cutting edges on my straight bits with a diamond honing tool whereas I can’t do the same with an up spiral bit. Even though I’m not using the router table’s fence to guide the work-piece and limit the cutting depth, the fence provides dust collection and a mounting point for a guard (Photo 17). I designed this template plate for routing half-blind dovetails in a drawer front.
In both styles, you can buy several sizes of bushings to correspond with router bits of various diameters. Once all the slots are cut, I remove the plywood from the melamine and cut the stops to length and width on the table saw and then cut the 1 1/2″ radius on the one end of the stops on the bandsaw. This is a brass router Template Guide Kit that contains one adapter, two lock nuts and seven different template guides in a plastic case. Fifth, guide the router around the sink so the bearing on the finger bit is rolling along the tape. This also holds true when using a router or shaper to flush-trim a curved surface.
I wasn’t crazy about the idea of only the magnets and weight of the router holding the router table insert down to the table when using large diameter panel raising router bits.

I will use the original tray to trace out the template to cut for it. These are made using King Starboard which is a high tech polymer/plastic material that cost a fortune so doing these once is really mandatory as I cannot afford to screw up the stock cutting it. So I will be taking extra time to make the templates perfect before using them. Standard bushes and those from independent manufacturers are mounted on an inner plate, which is adjustable for alignment, while the three extra-large ones fit directly into the machined recess in the router bases. The key is simply to have an accurate template and a router bit equipped with a guide bearing.
In the past I’ve made these router base plates out of 1/4″ Baltic Birch plywood and MDF but polycarbonate is a lot more rigid and longer wearing, that’s why I continue to use it. I start building the new base plate by cutting the polycarbonate to size and covering it with painter’s masking tape so it’s easier to see my layout lines. A good kit comes with a centering guide that insures the bit is in the middle of the collar.
With an inside template the cut is smaller than the template but with an outside cut the cut is larger than the template. Regardless of how you pursue woodworking, Router Boss will increase your productivity while still producing exquisitely precise and beautiful traditional woodwork. But you can also control precisely where the Router renders itself by using a global helper method. Virtually any shape can be made, the only limit being the diameter of the largest guide bush. When the router breaks through the material, the end battens support the edge from spitting.
It would also be possible to use double sided tape to secure the template, but it’s a lot easier to adjust the template using clamps. The collar guide has an on / off ring the precisely adjusts the inside / outside cuts to compensate for the bits width. Guides are especially useful in a low-production environment where you are making a number of the same pieces. But since we’ve now hard-linked our template to our subscription, we lose that option.
Removable pins or screws should be installed to align together them when routing provided that they do not protrude, and either damage the surface of the guitar body or hinder the movement of the router. Although there are a number of ways to cut grooves and dados with a router, using a template is among the most accurate methods – and in some cases the only choice available. It’s best to remove less material at a time and get a real feel for your router and the router bit you’re using.
With this setup, you would need to mark out your master template 12.5mm smaller than your actual joint line and then cut out and shape to the line. Straight away looking at the shots, I notice how clean the area is. in part this is due to the vacuum attachment to the router. Even though most straight-sided work is crosscut or ripped on a tablesaw, there are times when the tablesaw is not as practical as using the router and a template.
The curve of the template is then traced onto the workpiece and the work is band sawn to the layout line. Router Boss also works with scales and cursors, story sticks, and even your computer-made templates Stops in the T-tracks and base plate help you effortlessly position the cuts you desire, and built-in laser crosshairs and LED lights illuminate the work and show the exact center of your cut. Now wouldn’t you have to oversize the template to account for the bushing offset. I would for example like to drill dowel holes or domino slits with such a template. For convience, IR makes express’ body-parser available at Iron.Router.bodyParser.
A margin greater than 1 /16″ requires a heavy cut, which can cause tearout or pull the workpiece loose from the template. You may have wondered in the picture above what that pointy thing directing your attention to the layout lines is…it’s a $5 item known as a Center Finding Pin” and when it comes to accurately aligning the router for mortising, it’s devastating accurate…I have several. Now that the template is done, setup and cutting in the garage should be even faster than setup and cutting on the CNC router.
With the slots cut I’m now ready to trace the router’s original base plate holes for mounting it to the router onto the new polycarbonate base plates. When routing the end grain of a 2 1/2″ cabinet door rail for example, the end of the door rail butts up against this 1/8″ lip and can’t pass through the opening (window) in the top. Using an inside pattern is a pain in the butt because you have to be absolutely sure to keep the router pushed against the edge with absolutely no room for error…the slightest bobble will ruin the piece. Note that you don’t have to pass these specific five properties, they’re just the ones that make sense for Telescope.
Im going to drill a hole so I can get my 5 inch jig saw blade in there and cut it proud and then finish it with a trim router bit that has a top bearing. The On/Off” markings in the picture below represent the router’s on/off switch and I write this on the base plate so I don’t lose track of the router’s position on the base plate during the next few steps. Set up the router with say a 16mm bit in it with a base plate collar that is intended for use with that bit. A major benefit of Router Boss is its ability to show the cut you are making, while you are making it. You can cut to a scribed line as with hand tools, but with machine control.
