@splintergroup I’ve never heard laminating refereed to as breadboarding before, haha. With that said, my father suggested effectively the same thing. It’s not a bad idea, but there are a variety of cutting operations that, according to my current plans, would come between laminating the blank and cutting the deep hole, and if any of those force me to rethink geometries or shave a little here or there, I don’t want to then have my tube off the necessary positions. Moreover, since my impression is that a forstner bit relies heavily on it’s central point- hence why using a forstner bit to upsize an existing hole is difficult- removing the central material would be strolling it of it’s guide as it digs deeper into the wood, no? And since I’m looking at using an odd number of boards for my layup, not sure how what you’re suggesting would be feasible. Still, very clever. I’m not closed off entirely to the idea, just doesn’t fit well within my current intended specifics.
