Select a log with as few knots and defects as you can find. I ruled my pencil lines across the end-grain, parallel to the small crack you can see that has started to form - between the blue arrows.

Now cross-cut your log. My chainsaw will give me approx 245 mm length because I am cutting just insided the dashed blue line...

A few ax blows and the bump where the blue crosses were is gone. The mandrel can now bite into a fairly flat surface.Image

Depending on the depth of bowl I want, I can also split off the bottom...

I'll post a second series showing how I prepare the blanks with either an ax or the bandsaw :shock:

Thanks for these pics. Whilst I am nowhere near ready (time, tools etc) to try turning a bowl yet, though I will some day, your efforts to educate are greatly appreciated and I enjoyed learning a bit more than I knew this morning. The photos are great and the comments clear.

(This forum has more stuff in it than I can keep up with. So, in the better late than never department). Thanks Gavin, now I await Chapter 2, more-or-less circularizing the protobowl.
