Fixed Base Router Mortise,woodworking tools auburn wa,Japanese Garden Arch Plans - Good Point

Router mortising is very practical for small shop woodworking because it is efficient, produces great results and uses a highly versatile tool — the router. The plunge router is shown in its highest position in the photo immediately below and in its lowest position in the following photo.
The router collet is holding a sharp bit that is spinning at 25,000 RPM with the power of two horses so there is no room for compromise in quality. The 12-amp Elu router shown above has held up well over the years and is nearly identical to the current big DeWalt model DW625, which has a 15-amp motor. When mortising, the router bit must cut downward like a drill bit and cut laterally like a regular router bit. In upcoming posts, we’ll look at effective, inexpensive setups for mortising with the router. This is the type of router experience some of us might be familiar with but power tool design has come a long way in recent years and some of the most dramatic advances in precision have been in the field of routers. This article is the first of a series where we will be looking at every aspect of this versatile tool, from choosing your first router, to bit choices, to hand held use and router table operations and the various jigs that will help increase safety, speed and accuracy.
The current generation of routers offer more versatility, power and features than ever before and is without a doubt, the most versatile power tool you could own. The array of styles, prices and features available can make selecting the right router a confusing process – you do not want to overspend on features you do need, yet you also don’t want to find out your router choice is not ideal for the majority of the work you do.
The router is easily the most versatile power tool in your shop, and when used in combination with various accessories there is almost nothing that it cannot do.
In future articles in this series we will take a look at safely using the router for various hand held routing operations, routing using a router table and various router jigs and much more.
By Michael Kampen, Associate EditorMichael Kampen is an accomplished woodworker and writer based on Vancouver Island. In this post, we’ll look at the type of router you need for mortising, including some specific recommendations, and the right bits to use. This type of router differs from a regular fixed-base router in that the motor assembly can move up and down on steel posts while routing. Note that the fixed-base router, of course, has a vertical adjustment mechanism, but this is set before routing and is never used for plunging while routing.


Its slight taper fits into a matching recess in the router’s arbor (the third piece). Though the Bosch lacks this helpful feature, the 1617EVS motor can be used with the optional RA1165 base, which has an excellent micro depth adjuster designed for convenient use in a router table setup. The DW621 is another excellent, somewhat lighter, dedicated plunge router with integral dust collection, which the 625 lacks.
Like any other woodworking tool, routers can range from the most basic, inexpensive model with limited features to more expensive versions packed with features that come with accessories that expand the routers’ capabilities dramatically. If you intend on using your router all day long in a table or using a jig to cut joinery, your router choice will of course be different than were you to be primarily edge trimming counter-tops and panels.
This size of router will cover the widest possible range of operations the average woodworker might wish to perform. The advantage to this arrangement is that you can mount the fixed base in a router table and use the plunge base for hand held work giving you the best of all possible options.
Routers started out as single speed machines and with the advent of electronic speed control they have evolved into versatile machines capable of handling a wider variety of bits. From flattening large slabs of lumber to cutting functional as well as highly decorative joinery, the router can do it all. This allows you to plunge the rotating bit downward into the wood, lock that vertical position, then push the router to make the bit cut horizontally. Though each of these routers has a motor rated at 12 amps (120V), the plunge router is larger because of the plunge mechanism and has more widely spaced handles. Similarly, the Bosch 1617EVSPK is the 1617EVS fixed-base router plus the RA1166 plunge base.
These routers have the power to spin some larger diameter bits and as such are most often equipped with speed control.
When mounted in a router table, the big routers will eat raised panels all day long but when you remove that router from your table, it becomes a heavy cumbersome power tool. A fixed base router allows you to adjust the projection of the bit beyond the base plate while a plunge router allows you to retract the bit up above the base plate of the router. Plunge base routers allow the bit to be started above the work piece and then the bit is lowered into the work piece.


When buying a router, it is well worth it to get your hands on one to check out the features. In some cases you will need to fabricate specialized jigs and guides, but the creativity and control the router puts at your finger tips is unmatched by any other tool in your shop. Lacking spiral flutes, it also does not efficiently clear chips while cutting a deep mortise. They are limited in the work they can do and are only able to accept router bits with a ?” shaft but are light and easy to handle. Often sold as a kit with a plunge and fixed base, this is a cost effective way to get the most router for your money.
Consider what type of work you will be doing carefully before you choose one of these models as your only router.
This means that you can approach the material with a plunge cut from above where a fixed base router only allows you to approach the cut from the side. This is necessary when routing an opening inside a larger panel, cutting mortises, routing stopped dados and grooves and similar operations where it is not possible to bring the bit in from the edge.
Successive passes of plunging plus guided horizontal travel will produce a very clean, accurate mortise. At 2 ? hp, these routers will be able to work more effectively with harder woods, use larger bits and prove more reliable under sustained heavy use. Reducing the speed has the additional benefit of reducing the noise output of the router as well.
In most cases, the 2 ? hp kit is enough to handle most of the routing tasks the average woodworker will throw at it. In future articles we will take a closer look at router bits and their care and maintenance. While the increase in power increases the physical size of the router somewhat over the 1 ? hp models, the difference is negligible and they are still easily controlled during hand held use.
