I thought I would update on the results of my activities. Firstly a recap. I wanted a sit-stand desk for my study, plus one for my wife. Most are 1200mm+ wide, and I didn't want the desk to dominate, so needed one 1m wide (in black). I eventually found a manufacturer (in Croatia! with no reviews!!), and having bitten the bullet, I duly ordered it. To my relief, it turned up on schedule, excellently packed.
Putting it together was child's play, so I just had to make the top (25mm oak planks, 180mm wide, x4 for each top). I put a 45 degree bevel on three edges (using the tracksaw - I normally edge using the router table, but these tops were just to unwieldy to handle). A couple of holes (one for the monitor arm, one for the cabling). some sanding, and three coats of satin Osmo, and they were finished. Here the test fit.
The slowest part of the work was getting the cabling installed neatly. I had to add a panel on the non-rising frame for a mains extension block.
This extension block feeds two extension blocks fixed one under each (rising) top, with coiled cables enabling stretching as the table rises and falls. The panel also carries a small ethernet switch, again with one cable running to each computer. I would have liked this to be coiled, but such things don't exist in the length I wanted, so I settled for short cables which I made myself. One may I might coil the cable, but for now this works fine.
The computer CPUs are mounted vertically to maintain knee space under the desks. I considered making some frames myself, but in the end I thought that metalwork was more compact, neater, and easier to maneuver the CPU around in. Note my cases are very slim, so I needed some neoprene packing between the case and clamping arm. Incidentally, my computers have no moving parts - the case is designed to act as a heatsink, and the disks are SSD. You can also see the small enclosure (x2, everything is x2 on this project) to hold the PSU for the computer, fixed to the underside of the top.
The final installation is tolerably neat (as it ever can be with the nest of cables around a pair of computers), and with the over-monitor LED lights, I'm really happy with the result. It is very pleasant to be able to change one's position while working at the computer, and almost certainly better for my dodgy back to be able to work standing occasionally. With the monitor arms, it's possible to swing the monitors back against the wall very easily, providing a large flat surface for any other purpose.
