I installed an Avonite sink today and thought of a good question that could help me and others. Is there a better way to router those sinks that have a variable angle around the rim. In other words, the Avonite 3319 sink rim drops down at little angle and is consistant all the way around. Some vanity sinks will vary in angle from around the rim, ie, the angle keeps changing so a single bit doesn’t work well.

I saw a Wesly catalog the other day and they had recomended bits for different sinks, but how do you handle the ones with changing angles? Right now, I use a tilt base laminate trimmer with a 1/4″ shank bit and just keep changing the angle for the differnet sections of the sink.

Gotta be an easier way…… mabe something that floats with a spring loaded angle.

Any ideas out there?

Gee Al, Not sure what you really mean here? You have to be cutting a square edge in order to adjust the angle?? I just use a trim bit, not sure the number, it just trims the edge to an 1/8″ overhang. I then use the Roundover bit made for Avonite sinks, run it around. What is left does require sanding, there is a small lip, but a few minutes with my 3″ Dynabrade and I’m done

The sink will vary in angle in relationship to the deck. The avonite 3319 is almost square so it is easy to router. Some vanity sinks have a consistant angle so you use the appropriate angled bit for that sink. Some sinks angle will vary so the bearing on the cut out bit will be pushed away when the angle gets past a certain point, leaving the deck protruding in some areas and flush in others.

I’m not sure how much “protruding” you mean? I never get more that I can easily sand off. On the vanities I never have the roundover bit all the way down. Yes, it does not complete the full radius on top, but that is easily sanded to shape. When the bit is up a little, the bearing does ride closer to the corner where the two surfaces meet. Hope this helps KC

The important thing when trimming a sink for me, is to make sure the bearing has the same angle as the cutting edge. Most vanity bowls will change angles into the sink just a bit in the very front section. In the back of the sink it will be nice and flush. Take a DA sander with 80 grit and just sand the lip. It shouldn’t take more than 1-2 minutes to do. Then just switch to 220 grit and sand the rest of the bowl. If your fast you can sand a vanity bowl complete in 10 minutes.

We do the same as Andy describes.

On vanity bowls we run the bearing just below the glue line, then drop the bit to the deck for the radius and sand it in.

Maybe I am not explaining this well, but sometimes the sides of the bowl will angle out toward the center of the bowl. As the bit is dropped down past the glue, the angle of the bowl takes the bearing further away from the rim of the sink. We use a straight cut out bit, then an angled bit that will flush up most of it, but where the angle is the most severe, usually at both sides left and right, it leaves quite a ridge. With the avonite bowls it isn’t a problem, but with some of the imports it is. It is too much to sand. The only way we have found is to use a tilt base router and change the angle once or twice.

Next time I run into this, I will take some pics and post, perhaps that will help.

Al,

Just curious as to what import brands you might be using? That might help more than pictures.

[Andy Graves]

I only like to use sinks that are easily sanded. Otherwise it just takes too much time to finish the sink out. If you can’t just sand with 150 220 and scotchbrite the sink could be free and I wouldn’t use it.

[Virginia Fite]

Well, dovae has one that is a bargin till you start routing it. It is the worst offender, but the price can’t be beat. I don’t know how much extra it costs to sand out though.

[Shane Barker]

Anyone use the Atlas from Affinity that is advertised at $39.00.

Shane,

I have not used one yet. I did order one in and it seems to be a decent sink at least heavy like a acrylic or the like. I’m not sure about the platic peice left inside the overflow to the drain though. If you try one or get one mounted let us know what you think.

Reuben,

I have seen those plastic pieces like you are talking about
and they never have caused a problem for me in the past. Why haven’t you used
the one you ordered yet? Or was it just to check it out?

Shane

[Reuben Hoff III]

Shane,

. I had to order a sheet of their onyx color for a job, some template material so I thought just well add one on and have a little looksie. I have a small vaity job coming up so I think I will use it then.
