The bits are available individually, or as a complete set with the two matched rail and stile cutters and a raised panel cutter. If you do not have a variable speed router, then this type of bit will still allow you to make raised panel doors with your existing tools. Some sets, like the Craftex Blue Tornado R917 ( ) combine a pair of matched rail and stile cutters and a horizontal panel raising bit.Ī vertical panel raising bit can rout the same profile as the other type but the panel is run vertically along a fence instead. Using jigs it is possible to create arched panels with this type of panel raising bit. The panel is routed face down on the router table. As the bit diameter increases, the surface speed of the carbide cutting edges increases as well and when the bit exceeds the optimum value, the bit will heat up and the wood will burn. Horizontal panel raising bits tend to be large in diameter, roughly three inches across, and these must be used with a multi speed router. Panel raising bits can be either horizontal or vertical. When selecting a bit to raise the panel, you will be faced with several options as well. I find that the additional messing about that the reversible bits require not to be worth the marginal savings to be had when purchasing these over a matched set. Modern router bits are all ground on CNC machines and this ensures that they are a perfect match for each other. As the name suggests, a matched set has been manufactured from the start to function as a pair. After making the first cuts, the user must remove the cutters, reassemble them with the proper shims and then tighten the nut. With the reversible bit, the cutters and bearings are stacked on a shaft in one configuration for the cross grain cuts on the rails, and then reassembled in another configuration for the remaining cuts. These are available in two forms, either a reversible bit, or set of matched cutters. The bits you’ll need to make doors on the router table offer several options as well.
A cross slide sled can be as elaborate and luxurious as the Jessem ( ) or as simple as my favourite, a block of MDF cut square on the table saw for the purpose. You will also need a cross slide sled to shape the end grain on the rails.I prefer to have a sacrificial fence that I can close up on the bits to act as a zero clearance insert this provides additional support to the piece being shaped while also reducing tear-out on the finished piece. It needs to have a solid fence that can be adjusted to the bit.The table should not be dished or have a crown or you will not be able to get accurate cuts. The router table you use can be anything from a basic shop-made table to a top of the line precision router table ( freud.ca, ), but it needs to meet three conditions.
