Is this chamfer possible with a router? Maybe with a template. It looks like it could be done after it is shaped and assembled. I’ve had this transition in my head all night. I would like to know how to keep those crisp edges intact across the corner and along the fair. Alternative methods?

Sure! run the sole of the router on the face nearest you in the picture with an outboard template bearing.

Shape the curve. route the chamfer after with a bearing-guided
bit. You’ll need a big one.

You’d probably want to make a router jig to make the
curved seat. You can do it by hand too but results
won’t be as consistent. More fun to hack it out
than hang onto a squealing router though.

Thanks guys. I my have dust off the big orange ugly I hid somewhere. I think it will be the only router I have to accept that much bit. I would like to see how big of a chamfer I could produce with appropriate tooling. I may try work this chamfer in a project, something bigger and carry the fair over vertically too perhaps. I dig the stool though.

I found your bio an intresting read REO, thanks again for the brain.

Doesn’t seem hard, iffn’ I was doing it i would probably “nibble” into it with several passes, and be just fine.

I suspect the power tool jocks would be more inclined to use one of these to make a moulding a big as that… http://www.thewoodwhisperer.com/videos/power-carving-with-the-arbortech-turboplane/

Hello woodcox.
The chamfer on the chairs is not able to be done with a router, meaning a hand held router.
In saying that is not possible because of the size of the bit needed the size of the actual router needed with a base plate able to accommodate it as well.
Imagine a triangular shaped bit ( quite common) but twice the size of the profile shown, now we have a “huge” bit mounted in a hand held machine. Scary!!...Don’t try this at home comes to mind!

Its highly likely if its a machine produced run, the profile was done in a tilting head spindle moulder/shaper using a straight bit , or flat bed and specialised bit, it will not need a bearing as posts as profile jigs would be fitted.
It could however be done with a band saw incrementally then final finished by sanding.
Or as Benvolio suggested by using the Arbortech turbo plane, but again will require final finishing as you would not get a finish first up as per the photo.

Also keep in mind the crisp edges on at least the top would have to be smoothed over or ladies would kill you if it laddered their stockings or snagged their attire

You may also wish to contact John Makepeace and ask as a fellow woodworker they may provide an answer.

I for one would be interested in hearing the result

Enjoy
They look like nice chairs

I agree with Joey… I think you could do this with a handheld router with light passes. It would take a while, but it could be done. Whiteside makes bits up to a 1 1/2” cutting length.

With a handheld router, I might temporarily attach some extra material, along the insides of the legs, to add support for the router base. You could attach extra wood with carpet tape. You could also quickly make a large MDF baseplate for the router to span the corners.

I’d prefer to do on a router table or shaper. I haven’t seen any router bits with longer than 1 1/2”, so a shaper may end up as the choice if the chamfered face is wider than available bits.

Spokeshave, either freehand using pencil marks at your extents to guide you, or using a chamfer spokeshave.

The alternatives sound labor intensive because all of the setup and jigs required.

Whiteside (and I’m sure others) sells a stock bit that would cut a chamfer that size, no problem.

As for using the bit in a hand held router…myself, I wouldn’t hesitate. A table mounted router (if you have access to one) would be a wiser choice though.
In hard Maple, 2 to 3 pass’s max, and it’s done.

Guessing on pricing, but it’s probably a 60 to 80 dollar bit.

I agree with me too, It can be done, and I have done it. BTW my favorite way to “nibble” in on it is to start with a round over to get most of the meat out. Then slowly lower the chamfer down in a number of passes until you have it done. No prob.

I would use a router table, and light passes.
It would be too hard to keep the router from tipping with a handheld operation.

Good luck.

Thanks joey for the nibble tips. My baby girl is in need of a chair for her room. In hindsight, I’m going to use the chamfer bit I have in a smaller scale before springing for such a large bit.

It looks too big to do with a router, even incrementally, by the time you have got near enough you might as well have roughed it out with bandsaw or bow saw then smoothed it out with compass plane and or hand sanding or scraping. That applies for just one or two: if one had many to do then the right thing is the shaper aka spindle moulder which would do it one shot….
