This should be just be a little inspiration how you could build one. I saw many different similar videos, but never to slow it down with this little, easy, selfmade gear. I think with two more axes it would also work without the panel --> cheaper!

And the best thing on this concept: in fact you need just 3 tools. An auger, screw driver and a saw.

Slides of a 18h duration over 1 meter are in theory possible! And of course everything faster. Depends on which axes you assure the hairline, moreover on the panel.
