Thank you all.

Thanks, gents.

Tuna's right. About the model and about shop classes.

That one I modeled uses a Gold's Gym Dumbbell handle cut in half for the screws. $6.87 with the knobs at WallyWorld. The T-track is for hold down clamps. The guy who designed it clamps a saddle square on one side to align the work with it. He uses another hold down clamp to hold the tailboard while he marks out for the pins. He was using a Veritas saddle square but he made a new one of wood today.

Thank you, Liam I will give that a shot. From perusing the site, I've not seen many requests for furniture as old as what I'm asking. But who knows. Chris

A weakness for chairs is much better than weak chairs.

I agree, David. I would use a round tenon, too. Or just a big nail.

Outstanding progress

Thanks, Tuna. It was really pretty easy. Took me less than an hour, and that includes time to eat my PB&J for lunch and to find a good brass texture.

@davidheim1 said: The Dave Method (invented by Dave Richards, a constant presence on this forum) is a technique for intersecting shapes without problems. It gets around a SketchUp shortcoming: The program creates a hidden network of rectangles and triangles to create surfaces. But it also has a limit, and can't fill in those hidden shapes if they are too small, something like 0.1mm. However, components in SketchUp possess a property that gets around that size limitation: A change to one component produces the same change in every instance of that component. So here's how the Dave Method uses that property of components to foil that shortcoming in SketchUp. Let's say you want to intersect two shapes to create a cabriole leg. Make the shapes a component, make a copy of the component, and scale the copy up 100x, 1000x, or even 10,000x. Perform the intersect command and erase the waste. That will produce a clean, solid shape with no microscopic voids. Delete the scaled-up copy. The original component will also be a clean, solid shape with no microscopic voids. The Dave Method also works with the Follow Me tool. If you want to use Follow Me to create a shape, like an elaborate table leg with lots of small beads and coves, make the profile a component, scale it up, and use Follow Me on the big copy. If you only work on the original profile, the extruded shape will almost certainly have some missing faces. Hope this helps. Best, dh Perfect! Thank you!

Thanks, all.

Yes, great Layout presentation. Nice

Thank you gentlemen.

I don't see your image, either. Is there a question about using SketchUp to model this?

Thank you, tuna.

Yes that is tiger maple on a desk I made. It is a photograph not a render. Guess I need to be clearer or learn to render.......

Amazing and as I said before the knurling is unbelievably good, as is the redndering

Thank you, David. It is a perspective view but my template is set up with the camera focal length set to 75mm so the perspective isn't quite as pronounced as with the default 57mm. FWIW, the screw threads are all drawn to match the specs for the jig. Funny thing is the specs for the jig are metric (16mm x2 left hand and right hand threads for the central screw) but the drill guides are all bored for imperial sizes.

Thank's all. I stumbled across this while I was researching something else, and was fascinated by the history of the desks.

Thank you, tuna. Most kind.
