Milling Perfect matching grooves

I describe below a very simple method to mill such grooves, which does not require high technology and delivers perfect results.

Since I currently do not build furniture, where do I need such a construction, I show the procedure to some remnants of beech laminated wood.

First, the groove position is marked precisely. If in this example would be the groove used for a false floor, it does not matter whether one anzeichnet the top or bottom edge. You just have to be considered only in accordance with what has been characterized in the further course.

A board with a straight edge is aligned as closely as possible to the bottom line

Just on the line you now spans a board with a straight and clean cut edge. The material thickness of the board should be more than 12mm. Something can be found as always. In this case, it is a remnant of 18mm multiplex. For exact alignment is a universal fine a position to use: The Hammer. With this, the board edge can be aligned very closely on the line. Is everything that previously only lightly tightened clamps are pulled neatly laid.

At the edge of the board you now provides the einzunutende board, for example, a middle ground. A second board, as thick as the first applied to the upright floorboard and also fixed with clamps. Is the board upright slightly crooked, you push it to the second board straight.

The board is placed on the stop edge

Now is milled. The real trick is the router used. You need a trim bits with overhead ball bearings. This one drives from the board edges and so transmits the exact dimensions of the false floor on the side wall. which spanned boards serve as splinter protection and ensure a splinter edge.

The two board edges form the stop for the router

I have now several of these mills and use them very much for such things. If you have no router with appropriate length, takes you thicker, or thinner bulletin boards and balances the cutter length thus accordingly.

The results, which are achieved are so accurate that you should pre-grinding the items only roughly necessarily before milling. Otherwise, the Grooved board gets back unnecessary air.

Passt perfekt
A perfect fit

Fast schon zu perfekt
Almost too perfect

I hope this tip has been helpful to many readers.
