This style wheelbarrow (Plates [46] and [47]) is planned exceptionally strong and sturdy and will stand a large amount of hard usage. It is made larger and stronger than Type A, and is naturally a little more difficult to make, but well within the ability of an eighth grade boy. This type has removable sideboards.
The plate of details gives exact information how to make each piece, so it will not be necessary to give the directions here.
After all pieces are correctly made and all holes are bored at the places indicated, each part should be sanded very carefully and made ready for assembling.
Care should be taken to get good tight joints on the front brace, the wheel supports and the tops of the legs.
The metal braces can be made from strips of zinc 1" × 4", bent over the braces W, allowing a little freedom for removing the sideboards. Holes should be drilled in these braces, where shown, to receive 1/2" No. 6 round-head screws.
First attach the bottom boards to the handles with 1" No. 6 flat-head screws, placing the ends of the handles even with the front of the bottom board and flush with the side edges.
Next fasten the front and rear brace in place with 1-1/2" No. 8 flat-head screws, on the under side, and with 1-1/2" No. 8 round-head screws and washers from the outside of the handle to the brace ends.
