well, it's a good idea, but since I have a lathe, I turn my own..up to 11" diameter and 33" long..(I 'can' piece them together using compressed air canisters, but 33" is enough for most applications)...I can also produce very small holes...down to ΒΌ" diameter...which are useful for things like garden stake holders and inserts for toothpick holders..(which I make from exotic woods.)
