I found a circular form with a similar radius to the deck extension curve. I soaked the quarter-inch stock in a thermos of water, then pressed it around the form, securing it with wide rubber bands and tape.
The wall is three inches tall, so that’s 12 lengths of quarter-inch stock.
Here are the first four courses.
And the subsequent ones. One of the boards cracked at the curve, so I need to soak and form the final course… tomorrow. The rest of the wall is a great opportunity to utilize the many lengths of quarter-inch siding I have piling up on my table.
I wonder if an actual woodworker cringes at the imprecision of my efforts as much as I as do, say, when encountering bad typography.

Cringe? I think not. More likely marvel at your ingenuity!
I’ve been having a go at making mini rocks with fossils in them out of the Crayola medium (I used to live beside a beach that is part of the Jurassic Coast). so I’m looking forward to seeing the final colours/finishes of your work.
Hah, Barbara, I knew I was being a bit dramatic when I wrote that :) Another example of my tendency to focus on my effort’s flaws rather than the overall good.
Rock fossils is a brilliant idea, and I hope you decide to show your process!
Maybe you can add something decorative to cover up that tiny crack or make it look like a seagull or other aquadic creature did some damage to it? Maybe a nest of birds is in the little hole now? Incorporate it into the design and just roll with it. Either way it looks awesome.
What a great idea, Bennie! You’ve given me a whole new way to think about imperfection. Thank you!
Your curved deck and the cladding all look Fabulous to me! However you appear to be a perfectionist and there is nothing wrong with making it the way you wish it to be presented either with or without the crack in the curve. Justification can be applied either way but the most important thing is this; that the results satisfy You! :D
Beautiful Work!
Many thanks, Elizabeth. I do tend towards perfectionism, however imperfectly. All the voices in my head…
An important aspect of showing my work-in-process is the opportunity to engage with others who share similar interests. I am inspired and learn so from other builders!
