There are many routers available in the marketplace and the reality is that any one would probably work for a ProBox installation, but we recommend using a panel [trim] router. There are a number of reasons for this recommendation - inexpensive, easy to handle, lightweight, and they fit better on our jig.
Normal panel routers do not have a plunging mechanism which makes them a little less safer than a plunge router, we have sourced a small plunge router that has all of the characteristics of a panel router but with the addition of the plunge capability.
These routers are commonly available at places like Home Depot and sell for around $89! This router package includes an extra two handled transparent base that is perfect for doing ProBox installations.
This router is an amazing package, it is a variable speed lightweight plunge router that handles like a panel or trim router, but with the plunging ability. This is an ideal router for safely doing ProBox installations. The amazing thing about this router is that they can be bought for $100! This newer version is more powerful than the previous version. They are sold online from Klingspors Woodworking Shop, here is a link to their site Klingspors Woodworking Shop
In the coming months we are going to be offering a slightly modified version of this router that will feature a clear plastic insert for the router base that makes it easier to see what you are doing, as opposed to the metal one provided with the router. The modified base will feature an integrated router guide that eliminates the need for a bearing on the router bit!
Check back in the coming months for more details!
