Shop layout is all about making the best use of space. Place your machines so that you have adequate “safe space” that you need to work around them. The “buffer area” beyond that is the amount of room you need to run large stock though a given machine, keeping in mind that buffer areas can overlap between machines. If you want to get more organized, buy some 1/4-inch squared paper, make scale models of each machine including the safe space around each, and place them on your model shop layout. Remember that buffer areas need to be long enough to put an 8' sheet through a table saw, or a 6' plank through your planer, for instance. I raised my planer, so that I can use the area above my router table to pass long planks through the planer – all it takes is some modelling, and a little shuffling, and you will find the layout that works for you. Each space will have challenges; I had the area under the stairs that was wasted space, so I installed the dust collector there.
Use whatever image hosting service you like and post the link to /r/woodworking. The key here is it needs to be apparent that you've built the entry, and you follow the photo requirements listed in the contest rules. Submissions of finished photos only will not be accepted for entry. <-- I can't emphasize this enough, you absolutely need more than 2-3 photos for a valid submission. I will no longer accept entries that have albums that go from rough stock to 90% complete in one jump.
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.
