Dan Cooper Posted September 15 Report Share Posted September 15 Hi Woodworker Friends, Here’s my latest project. I like to challenge myself, and this one did the trick. Again, I spent hours going down blind alleys but in the end came out pretty good. I had to leave a few problems because they would have required taking everything apart. They are mostly errors of 1/16 inch and don’t show. Next time, if there is a next time, I could cut my time in half. But also, now I’ve figured out some techniques that could be used on other projects. By the way, does anyone know what this kind of chair is called? I just came up with Padded Chair, but I’m sure there’s a more accurate term. I’ll be interested in your feedback as to how you would actually build this. Thanks, Dan Quote Link to comment Share on other sites More sharing options...
lew Posted September 16 Report Share Posted September 16 Nice job! I like the padding details. If I were going to build this, I think I would extend the legs up so that the sides attach to the legs with mortice and tenon joinery. I think that would eliminate a lot of stress where the legs meet the seat frame in your design. Also, not sure how the seat back is attached to the chair bottom. That might be a weak spot? The style seems to mimic these- https://www.chairish.com/product/8524736/pair-french-style-open-arm-parlor-chairs Quote Link to comment Share on other sites More sharing options...

Masonsailor Posted September 16 Report Share Posted September 16 A lot will depend on whether you are using machinery or hand carving it. I’m a machinery guy so it would involve pattern making along with some bandsaw work and a pattern sander. Cabriolet legs for me involve cutting the blanks out on a band saw and then either free handing them on the drum sander and belt sander or taking the time to make the pattern for the pattern sander. The same goes for the back and the arms. Paul lew 1 Quote Link to comment Share on other sites More sharing options...

Dan Cooper Posted September 16 Author Report Share Posted September 16 Hi Lew, I think that's a great idea. The original legs I created had a rectangular piece at the top, but I deleted it and just went for the smooth transition. Oh and thanks for the "cabriolet" term. And I looked at the chairs and would have been a good idea to pad the armrests. Surprisingly, making the legs was the easiest part, by intersecting the silhouette from 2 sides of a cube.

Dan Cooper Posted September 17 Author Report Share Posted September 17 Hi Lew, I'm not sure what you mean, but if you want to copy the model you're working on to have another one on the same page, or to move to a new page. First make sure the whole thing is grouped by making a box around it with the black arrow cursor and then "make group" Then, while it is still selected, press Command - C on a mac, then move your cursor to the spot you want the copy to be and press Command - V. There's another way to do it, which I'll give you if the above is not what you're thinking of. Dan Quote Link to comment Share on other sites More sharing options...
lew Posted September 18 Report Share Posted September 18 Thanks for the information. With a couple of projects I have worked on, I thought using the intersect capabilities would create the required geometry. However, I had to do a copy/paste in place to get the component to be a complete solid. Just couldn't wrap my head around what was happening. I have been using Sketchup for many years but am self taught. There's still a lot I don't know! Quote Link to comment Share on other sites More sharing options...
Dan Cooper Posted September 18 Author Report Share Posted September 18 Hi Lew, Yes, doing intersections is a pretty advanced technique. Of course it's fairly simple once you get the principle, but not easy to describe in words. Here's two photos which show the setup. You push the silhoutte through the cube from each side, then select the whole thing, go to Edit - Intersect, then erase everything except the leg which will be in the middle. This example creates a leg that is curved in two directions for the chair. Dan lew 1 Quote Link to comment Share on other sites More sharing options...
lew Posted September 19 Report Share Posted September 19 Thanks, That is easier than the method I was using. This is NOT my video but it is how I worked thru it. Project 1.mp4 Quote Link to comment Share on other sites More sharing options...
4DThinker Posted September 19 Report Share Posted September 19 To achieve the look of the posted render the top of the leg could have shoulders for the side and front stretcher to sit on and miter together, but the rise up on the inside where screws could pass through to fasten to the stretcher inside faces. The height of the arms appear too low to bother padding them. Hard to know without sitting on the chair. Still useful to push against when getting out of the chair or hold onto when skooching the chair around while in it. I have some ancient software that ran under DOS. It would let you create 3D wireframed figures to import into AutoCAD Called Mannequin and made by a company called HumanCAD. Very useful to check, at least visually, the ergonomic appropriateness of CAD chair designs. They do make updated software for SolidWorks. Not sure if they make anything for SketchUp.
