D&RGW 50,000 gallon water tank, this one is a later version (post 1920's I believe) using an octagonal roof and individual concrete footing. Tank will have a pair of spout on opposite sides to service two tracks.
Interior form is a piece of PVC pipe to which three spacer rings were attached. These tanks tapered top to bottom so each spacer is a different diameter. Around this was fitted a Evergreen sheathing to provide an attachment point for the 2x6 tapered individual board sheathing. Then caps of more Evergreen. Tank form is painted black for two reasons, it masking any small gaps in the sheathing and when the Goo it placed on the paint it partially lifts it and forces it between to boards resembling pitch caulking on the staves. Floor is fitted next 2x8's all invidually stained before assembly then trimmed and sanded to match the profile of the sides.
