I got mine about a month ago. I finally got a few logs to try it out on. I was very impressed. Very first core came out right at the depth I wanted. All of the bowls were the same diameter but some were deeper than others. I was able to adjust it to core the same width but not as deep. A friend of mine with the Oneway said he can’t do that with his. I heard a lot of horror stories about learning curve and problems but I thought it was very easy to use and accurate right out of the box. A friend gave me three Mamosa logs and I cored out six bowls.

Thanks for the update @RustyFN!

Nice review.  Thanks.

I'm impressed! I had the Mcnaughton system and just never figured it out.

This is what I have done that made it easy. I bent wire to match the curve of each blade. I hold the wire at the depth and where I want the cut to start. I line the cutter up to match and lock down the banjo.
