When you are trying to build a boat outside, you need, not just good weather, but some likelihood of good weather for the next few hours.
So with showers making a regular appearance, I set up a "lathe" in my garden shed using a 650 watt drill, and a bolt set into 3/4 inch ply as a chuck.
I quickly gave up trying to use a chisel, perhaps I needed a little instruction, but the chisel simply bit into the wood and bent the bolt.
Attempt number two with a stanley surform round plane worked a lot better. I was able to shape some nice covers for the Center Board pivot.
A Forstner bit allowed me to cut a rebate on the inside to hold a gasket, since this will be oak on oak, a little rubber should make a better seal.
Now it feels like I am making progress again.
