Has anyone used these Birds-Mouth Bits to make staved cylinders?

I want to make a few kaleidoscopes and these look like they would simplify the process. In the past I have used the table saw but for the smaller cylinders and narrow stock I thought these might be safer as well.

An interesting side bar …. Looks like “free Shipping” from Amazon actually costs about 18 bucks if you compare the cost from Amazon Vs Woodline.

Here is the corrected link for Amazon.


I didn’t know these bits existed so I haven’t ever used them but they are interesting to me.

Thanks Kyle.

I corrected the link. Looks like Amazon moves stuff around.

Hi Dave,

I appreciate the offer but I don’t have Excel, or any other spreadsheet, on my system.

I was able to find quite a bit of info and an online calculator for masts and spars. The math is interesting. It is located here if you would like to take a look.

I plan to use staved cylinders in combination with segmented sections. They should look good once I get them done. I’ll probably vary the count in each section based more on appearance then function.

Thanks Again,

Hi Dave,

I could give that a try but I’m not sure if there would be enough interest.

I’ll add to this post as I go along and we’ll see how it goes.

I have one of Eagle America’s bird’s mouth bits. Works like a champ.
