Repeat this procedure to fasten the other half-drum to this same disc, placing it opposite the first
half-drum and aligning the tips in the same way.
Repeat this whole procedure to fasten the two appropriate half-drums to the top wood disc,
MAKING SURE TO MIRROR THE CONFIGURATION ON THE BOTTOM DISC.
Complete the assembly of the drums and discs by bolting (or riveting if you wish) the remaining
half-drums into place between the two disc/half-drum assemblies. Follow your marks on the
half-drums to get the right joints together.Any changes in shape in the half-drums caused by
handling can be overcome by hand pressure.
Cut a triangular-shaped notch with 2" sides into each half-drum lid between stages, centered 4"
from the inside edge of each stack.These notches will fit around the pipe shaft.
