hmmmmm – - – I googled “insect nesting aids” and now I understand.
I saw something like that on a Nature TV show a while back . . . .
here in Central Florida, we just leave the garage door open for a day or two. (joke).
best of luck in your projects – not too many people realize just how important
the beneficial insects are to our own ecosystem. without the proper pollination,
we could very well starve to death in less than a century.
~but~ I don t see any examples of insect nesting boxes that are perfectly smooth
and cylindrical on the inside (other than a pipe filled with straws or bamboo) – - – -
maybe you are overthinking your design just a little.


Well thank you John!
But the nesting boxes you described is exactly what I am doing. I fill the Pipe with bamboo and drill holes in the outer ring. I already sold some “prototypes” on a market and was pretty successful doing so. This is why I want to perfect the product and why I`m not too shy about investing some money.

You aren t going to be able to find a Forstner bit big enough to drill out a 4.7” diameter log on the lathe. You would have to drill multiple holes on the drill press and hog out the rest somehow. To use the wood lathe, you could drill a single hole in the middle and then use a hollowing tool to remove the rest, working in from both ends. With the 8” length, you will need a pretty long tool to safely reach halfway in from each end. (If I remember correctly the rule of thumb is 1 to 5 ratio of length past the tool rest to behind it.) A tool like the D-Way hollowing tool would give you a long enough reach. Sorby may make something similar and I ve seen some homemade versions of that tool online as well. You will need a chuck to mount the logs on the lathe.

Thank you for your feedback Lazyman!
I actually found a forstnerbit this big on the internet and I originally planned on making multiple drills and using a bigger bit each round.
But you actually brought up another idea in me! What if I use a metal lathe and drill a first small hole (2 inches) in the middle with a twist drill. After that i use a long wood turning tool, mount it on the cross slide of the lathe and increase the diameter a bit more each round?
