It started out as a Korber kit. I replaced the wood angle with styrene angle and the floral wire with brass wire. Also replaced the wooden dowel with a styrene tube. I made new footings out of styrene and a wooden footing for the delivery pipe. I bought the ladder and cage from Plastistruct. Dave wanted to have graffiti on the tank so he designed a walkway and railing which he cut on the laser. Dave then striped the legs, did lots of weathering and made custom brackets to hold the ladder at the right angle. By the way the picture of the water tank in the before state is Korber’s catalog picture. I would never bring a built model to The Center that clean!! The guys get on me for not dirtying up my models enough as it is.

I started making the storage container for the distillery. I’ll actually get double the number of tanks because it’ll sit next to the mirror. I certainly wouldn’t want to make a second one after the past several days of head scratching and rebuilding.

I wanted a set of spiral steps because it looks more realistic. But I had trouble calculating the length of the spiral stair risers for the tank. For the first try I made them the same length and angle. WRONG!

I found a spiral staircase calculator on line and after playing with it I realized just how simple it really was. It is simply 2 right triangles. One with the base length of the inner riser and one with the length of the outer riser. I drew the tank circle and then added the steps going around based on a scale 9 inches of tread and rise. That meant I would need 43 steps for my desired height. The steps would be 3/4" wideso the radius of the inner riser would be 2” or the radius of the 4” PVC pipe and the radius of the outer riser would be plus 3/4" or 2-3/4”. A little trigonometry and I’m done. A squared + B squared = C squared, the square root of C squared was the length of the riser. Ah my old surveying days back at work.

I wanted a landing half way up so the weary hiker would have a rest area. So I just added a half inch to the outer base length.

I drew the risers in cad and Dave cut them on the laser. They’re made from 1/64” laser board. I made 2 sets for the inner and outer and glued them together to get a thicker piece. I also added an outer piece.

Dave made me a soldering jig for the hand railings. Boy was that nice.

I thought the easier way to assemble the steps would be to glue each tread to the outer riser and glue the assembly to the inner one on the tank. I rolled the risers and the wire handrails to conform to the tank.

Here’s the inner riser on the tank.

And the completed outer and steps added.

The hand rail has been added and the sample walkway is just for testing.

I’m using a 3” PVC pipe cap for the dome. I added styrene strips to make up the 1/8” difference in diameter.

Ok we’re getting closer to the proposed finished look with a walk way from the tower to the tank.

I added pieces of .010" styrene around the 4" PVC pipe to resemble sheets of steel welded together.

Isn’t math wonderful? You just find the right formula, plug in some numbers, and voila! the answer pops out. And the model looks so good and you look so smart. Of course the secret is knowing such a formula exists and finding it, not always easy. And then you have to attach all those steps. Well done, Frank.
