I'm finishing up a Great Auk and am thinking about ways to hold down the flush mounted hatches. On my previous kayak I used the internal bungee method. That looks great, but I find it a little awkward to use in practice. The wooden cams pictured with the CLC flush hatch kit look like a good way to go--attractive yet easy to use. What's the best way to make cams like that? What hardware is used? I can probably figure something out on my own, but any advice would be appreciated. Thanks.
