Here’s the start of the sluice. When I ordered the parts, I found that I had one sluice frame. Not wanting to wait for an order, I decided to use that as a master, and I cast eleven more. I’m using styrene for the boards.
Here I’ve added some flow controls. They work, but only by sliding up and down. I didn’t threat the rod!
Although I haven’t decided on the final height or length, this does show the supports.
