Shelf brackets were purchased to act as floor stands. Four were going to be purchased for each gear board so two could be put in front and two could be put in back. This way the gear board would be unlikely to tip. Only two were purchased since brackets on the front would interfere with the gears. The brackets were aligned using a nearby piece of lumber while the gear board and bracket were held on a table. Holes were marked and drilled.

Aligning the shelf bracket

The brackets were added with #10 (5mm) bolts. Wingnuts were used in place of standard nuts so the brackets could be removed for transport. Weight was added to the bracket to keep the gear board from tipping over. This method isn’t elegant but the backside of the gear board shouldn’t be visible during operation.

Once the brackets were added the board was stood up. The weight of the motor helped balance everything but it was unstable without weights holding it in place. Ultimately, this should be a suitable way to present the gears.
