Depending on your situation, you may need to upgrade to 200 amp electrical service in order to meet the needs of your house and your shop. It may also be in your interests to add in a separate electrical service meter on your shop so that you can clearly write off electrical use for your business, or in future rent the space out and clearly separate out the utilities for billing your tenant. Generally, you don’t want to skimp on the power to your shop or on the lighting you include.
Perhaps the most satisfying move I made was to automate the dust collection system. I used the iVACPro system to link all machines to the dust collector. When I turn on any machine in the shop, the dust collector fires up and whisks the dust into the bin. The system also has a programmable delay to allow the dust to make it to the bin before the dust collector shuts down. I set my system for a five-second delay. The system works flawlessly for my band saw, planer, and router table at 115 volts, and also my table saw and jointer at 240 volts.
Let’s be clear about one thing: No workshop is perfect for everyone. If there were, I could simply give you a precise plan to follow with clear dimensions. Every person who comes to the hobby, avocation, or profession of woodworking has his own particular collection of tools and his own peculiar work style, skills, and desires for the kind of woodworking he wants to do that gives him a unique approach as to how he will lay out a shop: where the tools should go, where lumber and supplies are stored, and how much bench area he needs.
