It may not be clear yet, but you are building serious neural development in your arms, hands, brain, hips...whatever else it may be. The fastest way to get good at the fine work is to do a lot of the coarse work by hand early on, because the cost of inaccuracy or overdoing something is so evident and so fast. To rough saw 8/4 lumber and do it accurately so that planing is minimized is more difficult than cutting clean dovetails, but it's not more difficult to do rough sawing. Just to do it in a way that will minimize you're following on with a plane, and then the work keeping the plane in the cut and breaking chips to avoid unnecessary follow-on to that will make you better with a plane.Hard work and I’m constantly battling using hand tools when I’m surrounded by power tools! Still, it’s a challenge and ironically, I’m enjoying it because it’s hard not easy.
You're giving yourself free instruction more or less that you couldn't get from any guru at any price (partially because none of the gurus actually do much hand work - they do the work that beginners will do).
