I’m going to rout some flutes into the legs of a table I’m making. This is a photo of a piece of mass-produced furniture I have. I like the way the flutes taper to a point.

Can I replicate that with a router?

I don’t think you can do that by ordinary routing techniques. I would suggest using a gouge on the ends of the channels to get that look.

I wonder if you made a guide that had a ramp on each end would bit ride up and cause a taper? I am shooting from the hip here, and have never done this before. A core box bit has a radius on it so as it rides up the ramp the radius would get smaller.

I saw it done with a router that had a custom square baseplate (plywood), while using a fence and a wedge acting as a cam at the end of the cut to slowly and consistently lift the spinning bit out of the work piece.

this is similar to what I was saying, only I would make it a fixture, and using a bushing so all the flutes are the same. You get the Idea

You could go for a sloped fixture like the ones used to rout kitchen sink drainboards, http://www.mtmc.co.uk/Trend-DG/JIG-Draining-Board-Groove-Jig__p-17378.aspx

Another option is to use a large diameter fluting bit, like this one: http://www.leevalley.com/en/Wood/page.aspx?p=30155

I used that bit to make the flutes on the side of this plane: http://lumberjocks.com/Iguana/blog/40731

Maybe not quite as tapered an end as you are looking for, but it is a straight cut, no ramp involved.

Harvey,

I’ve always done my fluting on my table saw. I purchased a used Craftsman molding head with a variety of interchangeable cutters. The old kit I had did not have an actual fluting cutter in it, but I took one of the old cutters and reground it to make my own fluting bit.

I’m sure I could have bought the regular fluting bit, but at the time I worked with what I had and it has worked so well that I’m still using it.

I never cared for the spoon look at the end of a flute when done with a router because it never looked like what you would see on furniture.
