Making cross table

Hello.
I would like to show you my idea for a cross table for the WS-15 bench drill.

The body of the table is a 15mm sheet of metal to which I screwed some prisms I found in a nearby scrapyard.

The second part of the body is made similarly, except that I added a square steel rod with threaded holes to be able to push one of the prisms to remove the slack.

The element that moves the table is a 16x4 trapezoidal screw which I threaded at the ends to a 10mm thread to be able to mount the knobs.
I made them from a piece of sheet metal, a pipe and a rod.

The second axis is a sled from some large lathe found on scrap.
After disassembling, cleaning and lubricating, they fit perfectly into the lower body of the table.

The WS15 does not have a pin on the top to hold the ER20 handle, so I came up with the idea of blocking the walrus cone using screws screwed into the handle's blade. The quill has a knockout socket at a slightly angle, thanks to which we tighten the handle by screwing in the screws.

The whole thing was extremely stiff and heavy (about 55 kg).

The entire stage of work on the table is in the video below.
