A cheap, Effective, Easily Constructed Dry Box

An effective dry box can be constructed from a os glove bag, quarter inch a d . aluminum tubing, elec- ""7 trician's taoe and rubber tubing. The advantages

of the dry box are: The dry box is easily moved; ,%:; since i t is completely clear, i t gives a. good view of the

working area; the aluminum tubing can be bent once inside the glove bag tg accomodate various shaped objects; the glove bag is easily replaced if i t

rrm,. becomes punctured or contaminated; and the

I c,.ws n r r crossed rather than a square construction of the front

of the frank adds strength to the structure, and oer- mits the natural positi&ng and greater maneu;er- ability of the users' hands.

* ='+ The construction is ar follows, using a 37 X 37 X 25-in, glove hag.

1) Cut end bend the aluminum tubing as shown in the figure. 2) Attach the ends with rubber tubing and tape to prevent any sharp cutting edges and then tape - -

the joints. 3) The frame is bent in order to fit through the glove bag opening and then formed to the de- sired shape once inside the glove bag. 4) The gas inlet consists of apiece of aluminum tubing with the cut end taped to prevent punctur- ing the glove bag.

The typical cost of constructing such a dry box is: Aluminum tubing '/,-in. 0.d. X 50 ft, $4.00; rubber tubing and tape, $0.50; and Glove bag, $6.50, giving a total of $11.00.
