This Square Bowl is one of my first major woodturning projects. I had seen plenty of turnings which did not have a traditional round shape and I tried to figure out how they did it. This bowl is my first attempt at creating at turning of a non-round shape. In fact it is probably only my third piece I have ever turned.

This bowl is made from Walnut and was turned on my old ShopSmith (I have since moved up to a Nova 1624-44 lathe). The method I used here, as you can see from the photos, was to glue poplar wasteblocks to the edges so that I could turn the bowl round. Once the turning was complete, I used my father in laws bandsaw to remove the poplar.

If I was to return this project today, I would start with a square blank, skip the poplar waste blocks and turn at a much higher speed. I don’t think I went much above 800 rpm when I first turned this, but would probably turn close to 2000 RPM today.

That is a nice piece. But the way ‘they’ actually do it is to spin it square. ‘They’ call them knuckle busters… as you can see why.

Kerux – Totally agree. As you can see from my later work, I eventually figured it out. This is a case where as a newbie, you often do what makes sense to you at the time. If you had said I needed to turn at 1500 rpm on my ShopSmith, I would have run away screaming ;)

I have turned several “square bowls” of a slightly more complicated design than this one. See Project postings for about 8 days ago 12/29/08. I find that in order to avoid tear out of the cross grain at the corners of the feet you need to glue on at least a 1/4” waste strip on the edges of all 4 corners. Your method actually adds one useful feature in that you can sand the outer tips of the feet on the lathe. I have to sand mine by hand.
Looking at you other postings I see you are well on your way to bigger and better turnings.
