Ok, I tried making a few stopped flutes which terminate with a taper
using a wedge as discussed in a previous thread. (Suggested by SonomaProducts) Here is the result: http://www.garagewoodworks.com/shop_talk.php Came out ok. You can definitely see where the taper begins in the flute (not a completely smooth transition). This can probably be fixed with a piece of sandpaper or just leaving it alone. |

IMHO the stopped end looks better with out the taper. And you don't have the shutter as the router changes direction. I have an example on a.b.p.w. |

I think the source of the problem is the abrupt transition between the flat surface and the wedge. A three-fluted bit /might/ (or might not) help with the slight side "dwell" marks at the transition. If I were trying to do this on the CNC, I think I'd radius the transition rather than do it as two straight-line movements. -- Morris Dovey DeSoto Solar DeSoto, Iowa USA http://www.iedu.com/DeSoto/ |

Gravity will not be working against you and there should be less shutter. |

Gravity will not be working against you and there should be less shutter. Something you might also try. If the router is on an auxilary base, bevel the leading edge that meets the wedge to the same angle so that the base does not have as abrupt of an edge to catch. |

Hmm, I don't recall having these problems but it has been a while
since I used this detail. I just did my own fireplace and would have liked to do it but was in a bit of a hurry with other pending projects so I just did standarad stops. I do recall that I usually used a very large add-on base on the router to add more heft to the router so maybe the inertia overcame the stall at lift. I think beveling the front edge of the base and using a radiused ramp will both be added to my repitoire. Really nice work. Such a small little difference but it will please your eye forever; just like my round ended flutes on my firplace bug me every day... :-( On Nov 21, 3:53*pm, GarageWoodworks wrote: On Nov 21, 6:03*pm, Morris Dovey wrote: GarageWoodworks wrote: Ok, *I tried making a few stopped flutes which terminate with a taper using a wedge as discussed in a previous thread. *(Suggested by SonomaProducts) Here is the result: http://www.garagewoodworks.com/shop_talk.php Came out ok. *You can definitely see where the taper begins in the flute (not a completely smooth transition). *This can probably be fixed with a piece of sandpaper or just leaving it alone.

As the router starts to climb the ramp, it is only supported at two points due to the round base plate. Using a square baseplate will make transitions smoother. |

My router PC plunge is round on one side and flat on the other. Initially I was climbing with the round side and it had a tendency to wobble as you stated. I flipped my fence to the other side of the router and climb with the flat side. Much easier this way. Good tip. |

Then sharpen the tip of the wedge down to a micron, Brian. Voila! No transition marks. P.S: If the wedge is thick/tall enough, there is no need for a radius as the bit will be clear of the work before it gets to the top. -- We have too many high sounding words, and too few actions that correspond with them. -- Abigail Adams, letter to John Adams, 1774 |

How about sanding the edge of the plastic base plate on the router itself to make the transition smoother whether going up or down. |

If I were trying to do this on the CNC, I think I'd radius the transition rather than do it as two straight-line movements. Hmmm. *I'm not sure at the moment how to make a wedge with a radius, but I'm sure it can be done. * I need to think this one over. Even though the wedge is knife sharp, the router base still stops when it hits then I lift and climb. *At the transition point in the flute it almost makes a step. *It's as if any edge in the wedge is magnified in the flute. *I need to think about this one. *Thanks Morris! How about sanding the edge of the plastic base plate on the router itself to make the transition smoother whether going up or down. Not a bad idea. *I think this is what Leon suggested above. *In the process of making more practice cuts, I found that with the radius'ed wedge and a feathered edge on the wedge works nicely. *Coming down the wedge seems to be the best approach. Interesting note, that in discussing the tapered stopped flutes with the client, he wanted tapered stopped flutes on both ends of the flute (Uggghhhh) I would need a ramp at both ends (go down and then go up a ramp). Fortunately, I talked him out of it.- Hide quoted text - - Show quoted text - |
