Ok, starting with my reversed engineered model of the table, it was time to get to work (I am not a real-time blogger, so this and the last few posts cover about a week).
My design criteria -
1. Large (72×40) table extending to full-sized 108×40 table
2. Maintain design elements of original but highlight additional tooling and higher quality wood
3. Buildable (by me)
I decided to use equalizer slides rather than the ones where you move the legs. This causes some problems but avoids others. The biggest reason to use these is so one person can open the table and put in the or take out the leaves. Rocklear has these, I made a quick CAD version and dropped them in. Putting slides in means that the original cross truss under the table has got to go. I will pay homage to it with some paneling around the legs and support structure with similar angles.
I love the look of the legs in the original, but they are a little concerning structurally. I’ve put a panel in them which I think will look great with contrasting woods. I then rotated the legs to match the angles on the truss in the original. I had to learn a bunch of things about the CAD system to do that.
The original tabletop is quite bland. This seems like a great place to use contrasting wood colors. SketchUp (with some texture packs) lets you drop in some textures which was kind of fun. I really like the look of dark wood for the outer portion of the legs and the table edging. The striping thing was just a whim. I am planning making the table-top and the leaves have that interlocking offset pattern. It may be a bad idea (someone tell me please!), but that’s how I learn.
My biggest concern is if the cross pieces that the slides sit on is beefy enough to support this thing. Seems like it ought to work. I Also am not sure if a glue or glue and biscuit joint is going to be enough to hold the tabletop together – do I need rabbets or something similar? Maybe just some cross pieces under the top and above the slides…
I goofed somewhere on the height – I intended the top to be 30 inches and somehow got it to 31.1 Doh.
