Thanks for the explanation Soupysayso. Each of us finds joy in some part of the lure making process, for you it is in the "details". You made me realize too that I am not as much the spaz I thought I was for perfection, lol.
I respect your lure-building process, you have certainly done your homework, and reading different routes to the same ending (a cool lure) is how we learn. I will add though that some of the variation you strive to eliminate is exactly what I find most appealing. Wood is alive, and feeling a lure take shape in your hands is where the fun is at for me. By removing the wood from the center of the lure, you're removing the very "heart" of the critter.....in my humble opinion.
The measurements I make while building a lure are done to provide predictability, not certainty. If I were so serious as to want the wall thickness of my lures to be within .001mm, I would take out a bank loan, purchase machined molds, and begin plastic injection molding.
Why fool with wood? Sounds like you would very much enjoy the results from molds as they provide repeatability and precision, right down to the fingerprint you left on the prototype. I like them too for production, but for just "good ole traditional lure building fun", wood is impossible to beat.
Thank you for the exchange and best regards,
