An inexpensive tripod holder, one that will prevent the tripod from slipping on a smooth floor, and prevent the points from doing damage to the polished surface or puncturing an expensive rug or carpet, can be made in a few minutes' time, says Camera Craft.
Secure two strips of wood, or ordinary plaster laths will do, and plane down to a thickness of 3/16 in., for the sake of lightness. Cut them to a length or 40 in. and round off the ends to improve their appearance. Take the piece shown in Fig. 1 and drill a 1/4-in. hole in the center, and eight small holes, 1 in. apart, at each end. In one end of the piece, Fig. 2, make the same series of eight small holes and, in the other end, drill six 1/4-in. holes, 3 in. apart. A 1/4-in. flat headed carriage bolt, about 1 in. long, completes the equipment.
The two pieces are bolted together, not too tight, and the points of the tripod legs inserted in their respective small holes. So set up, there is absolutely no danger of one of the legs slipping out of position. By moving the position of the bolt from, one to another of the larger holes in the strip, Fig. 2, almost any desired inclination of the camera can be secured.
The same sort of simple apparatus built slightly stronger, and with a small caster under each of the three series of small holes, makes an excellent tripod clamp for use when the camera has to be shifted about, as in portraiture and the like.
