Thanks!
If you’re going to buy these kits, be aware that the tube is a true 1”, NOT a 25mm, and if you bore the hole with a 1” Forstner bit, it’ll be a tight fit. I might try wrapping some 60 grit on a stick to open up that hole a bit on the next set, or maybe see if I can find a 26mm Forstner bit.
I like that both of the woods came from our lot, but I’m keeping my eye out for other overgrown lilacs in the neighborhood. It’s a pretty wood, but hard to source, go figure.
