Then, using G as a center, strike an arc with a
11-1/2" radius. This forms the rest of the inner trace of
the bucket.

Cut the plywood along this line and along the lines that
form a quarter ellipse. Using this as a pattern, cut
several more quarter ellipses from scrap. Nail these to
stretchers to make a bending jig around which the buckets
may be formed.
Weld Wheel Parts
Welding of the various parts of the wheel produces an
exceptionally strong construction. After getting together
or making all the required parts, begin the assembly by
welding four clips to each end of the hub sleeve. Then weld
the required number of clips to the shroud plates for the
sole plate, and weld the shroud plates to the clips on the
hub sleeve. After welding both hub flanges to the shroud
plates and the sleeve with a continuous weld, attach the
sole plate to the clips on the shroud plates with No. 8
self-tapping screws. Also weld the sole plate to the shroud
plates with a continuous weld, and the bucket-support
angles to the sole plate.
Attach wooden buckets to the supports with 3/4" No. 10
roundhead wood screws, and then drill holes 2" from center
to center through the shroud plates for 1-3/4" No. 10
roundhead wood screws. If you use steel buckets, rivet or
screw 10 clips to each side of each bucket and attach the
buckets to the angles with No. 8 self-tapping screws. Then
drill holes through the shroud plates in the way of the
clips for the same type of screws.
Lubricate Bearings Well
Using locknuts and washers, fasten the hub sleeve to the
shaft with two 3/8" by 4-1/2" bolts, placed at right angles
to each other. Two bearing mountings having 2-3/8"
renewable liners with shoulders should be bolted to the
foundation. Place shims about 1/4"thick under the bearings.
Standard bearing mountings, variously called pedestals or
blocks, may be bought complete with wick oiler or cup oil
reservoir and with built-in self-aligning features.
Standard bronze bearing metal liners or inserts likewise
may be bought from any machine component supplier. Babbitt
liners are equally satisfactory.
Although the wheel turns slowly, it is heavy and will be
running almost constantly, so good lubrication of the
bearings is essential. To this end, care should be taken to
insure that the bearing liners are finished to the correct
fit. Porous inserts or inserts containing graphite are
excellent for this application, but may cost more than
regular bearing inserts.
