This is simply a stout frame on 4 legs 9-12 in. high, made of quartering which may vary from 2 in. sq. for small casks to 3 in. sq. for larger ones. The proportions given in the annexed illustration (Fig. 571) are suited to a 9-gal. cask. This should be 22 in. long, 15 in. wide, 9 in. high, and made of 2 1/2-in. stuff, of which it will consume about 9 1/2 ft. run. It will be seen that the sides a, b are joined to the legs c, d, e, f by mortice and tenon joints, while the ends g, h are dovetailed into the sides a, b. The joints are secured by pins of oak or red deal driven into holes bored by a gimlet. The stand thus made is only adapted to carry casks stood on end. For holding them steadily on their side, and at the same time giving them a tilt forward to allow all the clear contents lying above the sediment to be drawn out without disturbing the barrel, use is made of 2 pieces of board hollowed out to receive the barrel. For the sized cask mentioned (9-gal.), 15 in. will suffice in length and 1 in. in thickness for each piece. Both are prepared for letting down into the frame by cutting out a piece 2 1/2 in. sq. from each of the 2 bottom corners as at a, and can then be screwed to the cross piece b of the frame.
Previously the cradle is formed by describing on the piece of wood an are of a circle corresponding to the size of the cask at the point where it is to be supported. Supposing the diameter of the cask to be 15 1/2 in., the radius of the circle to be described will be 7§ in., as shown. This gives the correct arc, but as the cask will lie sloping and not flat, the foremost edge of the are must be shaved away till the cask will rest on the entire breadth of the edges of the cradle c. For the front cradle the board may be 6 1/2 in. wide, and for the back 8 1/2 in.
