In the segment where he about to install the router under the table, he handles what appears to be a piece of material attached with cord, lowering it and then returning it to the top edge of the table. Once the router is secured via it's rails, he moves the object and places it over the centre of the router top cover. Later when the table is secure on the frame, he starts twiddling with the winder arm beneath the table at the front, and you see the winder operating a threaded rod and winding a block toward the front of the table.I couldn't quite see how the crank for the height was connected to the router, but it was a nice method.
I was thinking about it when the russian guy turned the RT from vertical to horizontal but his solution for the counterweight was simple.Wow! That's pretty much a masterpiece. The fence alone is wonderfully versatile. I couldn't quite see how the crank for the height was connected to the router, but it was a nice method. Put a bucket or wide pail underneath to pick up some of the sawdust. Even when you turn it vertical, the center of gravity is still within the base (I'd put a sandbag on the crosspiece just to be safe).
