Last night’s lathe practice was about making my own tools. All 622’s wheels need a ridge at the edge of the tyre, and so, I made a little boring tool to create that.
Once done, I tried it out and made the test wheel shown here. The wheel is the size of 622’s engine truck wheels, minus the flange. I was surprised by how small these wheels are: they look way bigger on the computer screen. They say that television adds ten pounds, but I didn’t realize it applied to wheels too.
The back of the tool even knocked off the hub, and somehow, eight spokes need to be cut into the wheel too. I may have to rethink the design of these little guys.
