There are, of course, other useful forms of apparatus involving more or less woodwork, such as hanging poles, fixed upright and slanting poles or bars, and various contrivances which you can readily arrange without more special instruction than has been given.

Ladders are of course good, but it is usually as well for the amateur to buy these. A suggestion for a framework for hanging rings, trapeze, poles, rope ladders, and the like, with fixed ladders and horizontal bar, is given in Fig. 279.

Fig. 279.

Do not make such framework too light. Fasten the joints with bolts rather than screws or nails, and suspend the hanging apparatus from eye-bolts passing through the timber and with washers under the nuts. The dimensions for such framework must depend upon the circumstances. The suggestions about the construction of the other pieces of apparatus given above will assist you in designing and constructing something to suit the circumstances.
