Default chamfer bit routing

Looking for proper way to use a chamfer bit. I'm using a Kreg full sized table with a 7518 Porter Cable router. I'm looking at cutting a 45 degree cut on the end grain of red oak. The stock is 5/8 thick. Question is............I would like to cut the 45 in one pass. The end stock is 90 degrees and I was hoping to cut it only once. I realize that the 45 degree edge will be just shy of 1 inch in length after the cut is made. Can it be safely done and do I have to reduce the router speed. Any assistance would be great as I have several of these cuts to make. Thanks in advance. Ron

With a sharp cutter and enough power (and the P-C 7518) has bags of that I don't see why it wouldnt work. Personally I wouldn't reduce the cutter speed because you'd possibly find the router bogging down in the cut. If you hit a problem of scorching of the end grain then you're feeding too slowly

Hi Ron

Two things: Use a sacrificial backing piece to prevent the job tearing and use some sort of sled to hold the pieces firmly at 45deg to the fence. You don't have to buy one. They are easy enough to make. In fact, for 45degs you'll probably have to make one. I'm not sure the commercial ones do anything but 90deg.

Cheers

Peter
