To use a mortising template successfully, it is important to know which bit and guide bushing to use with it.You won't have difficulty with this when you use the template immediately after having made the template. But how about a ycar later? Or five years later?
I think it is essential to annotate the templates that are going to be keepers. Just write legibly on the template what bushing/bit combination is supposed to be used with it.
Now, as you prepare to make another five-board bench, you get out the template, then fetch the correct bushing and bit from where they are kept in your shop.
1. Set up the router. Stan by fitting a %-inch guide bushing into die bit opening in the router baseplate. Next, tighten a '/»-inch straight bit in the collet. A spiral
The completed mortise is clear* and accurately sized and positioned.
Crosshairs allow you to position the template without laying out the mortise completely on the work. Just lay out the centerlines (length and width) of the mortise. Then align the crosshairs on the template with these lines, as shown. The mortise will be perfectly positioned.
2. Lay out the mortise on die workpicce. This doesn't mean you must draw rectangles on the work-piece. delineating each mortise to be routed. Rather, it means you should scribe the ccntcrline and midpoint of each mortise on the workpicce, so you can line up the template. If you've made the template with precision, and your layout lines arc accurate, the mortises will be properly located.
3. Position the template. Lay the workpicce on an expendable piece of scrap that will back it up, eliminating chip-out on the underside of the workpicce and protecting the bench top. Set the template on the work, and align the midpoint mark on the template with the corresponding mark on the work. Apply a couple of clamps, clenching the template, workpicce. and backup scrap to the workbench.
4. Rout the mortise. Set the router on the template with the bushing in the slot. Switch on the router, plunge the bit, and rout the mortise. The routine 1 usually follow is to plunge-bore the corners of the mortise to full depth and then make a scries of increasingly deeper passes back and forth.
