When Bruce first mentioned his technique to me I was excited. Now when I actually see what he has developed I am blown away.
Way to go Bruce.

Great video, it really makes things easy to understand.
I love the "thinking out of the box" process.

Because you are cutting really in two directions at once, spiral blades work the best. We tried several times to make it work with flat blades, but we kept breaking them.

Mike has raised the question of using flat blades for cutting spirals. The answers are "no", and "probably not".

To cut the pattern shown in the video (and in the magazine), it is necessary to reverse direction of cutting while the blade is in the middle of the dowel, this is only possible with a spiral blade.

For an open spiral, e.g., one which runs all the way to the end of a dowel, it might be possible to use a straight blade provided that the depth of the blade is less than the kerf width (I don't know if such blades exist). If the blade is too deep it will bind and break and/or burn the wood.

Great artical!
I experimented with this exact thing about a year ago. I did not try a spiral blade, that looks like where I went wrong. I did it very similarly set up to what youve got in the video, and no, flat blades didnt work at all.I didnt really notice any binding during cutting and spinning, but because of the blades tendancy to drift, it was impossible to keep it going where it was supposed to. At any rate, I gave up toying with that idea.It is great Bruce conquered it, its something that really will add a 'new twist' to a lot of projects!!! Great job Bruce! And, thank you Fox Chapel for putting it in the pages for the rest of us! Now, I just got to wait for the new issue to arrive!!

WOW. This is one of the coolest techniques I have seen in a long, long time. This might actually get me back in the shop. Thank You Bod for showing the video.

Bruce,I've watched the video twice now but the speakers on my computer don't work properly so forgive me if you said this in the video- but what size spiral blade do you reccomend? Can't wait for my issue to come in and get to read more about it!

Thanks, Jerry

Actually...I did the voice over for the video and Ben Fink did the cutting in our creative director Troy's shop....and I didn't mention what size blade to use. The article suggests using a #3 spiral blade.

Bob,

Maybe you should warn Mike (FD) to stock up on spirals?
