Steven, Welcome to the forum. This is a diverse group of individuals from all "corners of the planet". We are glad you have joined and hope that we can help you and conversely, you can help us back. Routers are some really cool tools, but most of us; in addition to having an interest in routers and the work that can be done with them have an interest in woodworking and often utilize many other tools as well.
You mentioned "building the tools you use" and most of us do quite the same and enjoy every minute of it, Wood working encourages innovation and ideas that develop into helpful creations tend to open our minds to additional possibilities.
I am involved in product development and try to stay well aware of new tools with new ways of doing things. In most woodworking, there are numerous ways to accomplish a task and over time we all tend to choose a way that works best for each of us.
Sequencing projects is a bit more interesting and involves careful planning "seasoned" with experience. Try doing this: If you have numerous projects that are alike, time yourself on the ASSEMBLY of the first one (but do not take any safety shortcuts), then time yourself on each sequential one. You will probably notice the time durations decline with experience and familiarity. Often after milling parts or assembly we can look back on our work and see places for improvement. In reality, multiple similar projects often benefit from milling all similar parts at the same time - but only after you are certain that everything is cut to exact requirements. Have fun, Be safe and THANKS AGAIN FOR JOINING.
