Just a short blog today to tell you what I’ve learned and to give you a few tips. Today I planed 6 stave’s concave and also cut out the dados in them for the bottom. As I mentioned in a past blog, it is easy to cut the lines marked out for the dado.
I first scored with a knife. It’s a good idea to just lightly score the lines much like the pressure you might use on a pencil, then cut deeper the 2nd time. This will keep you from wandering off the line on the first cut.
After that it’s using the lag knife. It is amazingly easy to use and you can get a lot of pressure on it with the long handle. You just have to be a little careful at the sharp outside edges of the staves so you don’t break them out.
The photo below shows me starting to chisel out the waste. Here again you need to be a little careful with the edges. I started the cut with the bevel up and then reversed it to bevel down about a third of the way into the cut. This makes it easier to follow the curve of the stave evenly. If you should take a chip from the edge, it will likely be near the inside edge which will be planed away when you plane the edge angles. I am doing the edge angles last for that reason.
Here is the first one finished.
And here it is with the bottom inserted.
And with a few staves set up. Please note that I have put the long handle stave’s at one end of the middle board and the other will be at the other end directly opposite. this will be the strongest way to mount the handle stave’s to reduce stress on the bucket bottom and structure when it’s filled with liquid.
One last point. I originally ground my plane iron to the same radius as the stave’s would be. In retrospect that was a mistake, although it worked ok, I still felt it wasn’t optimal so I reground my blade to a tighter radius and that made a significant difference. Better control, Faster and better. I’m sorry I miss-led you on this point and I hope it won’t create too much work for you if you choose to regrind and hone your plane iron.
I hope everyone participating in this project is having fun and learning something new, as I am. Thanks for reading.
